element组件中参数这么等于data element常用组件

7.组件框架

7.0.Element UI

js -> jquery ->jqueryui /easyUI / bootstrap UI

js -> vue -> elementUI

vue 2

https://element.eleme.cn/#/zh-CN

$ npm i element-ui -S
<!-- 引入样式 -->
<link rel="stylesheet" href="https://unpkg.com/element-ui/lib/theme-chalk/index.css">
<!-- 引入组件库 -->
<script src="https://unpkg.com/element-ui/lib/index.js"></script>

在 main.js 中写入以下内容:

import Vue from 'vue';

import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';

import App from './App.vue';

Vue.use(ElementUI);

new Vue({
  el: '#app',
  render: h => h(App)
});

7.1.分列

一行 24列

<el-form-item label="标签" prop="id">    
      <el-col :span="6">
		...
      </el-col>
      <el-col align="right"  :span="3"  >标签    </el-col>
      <el-col :span="6">
		...
      </el-col>
      <el-col align="right"  :span="3"  >标签    </el-col>
      <el-col :span="6">
		...
      </el-col>
    </el-form-item>

7.2.上传下载

7.2.1.1.上传组件
<!--
            list-type:  文件列表的类型	string	text/picture/picture-card	
            action :  必选参数,上传的地址	string
            :accept :  接受上传的文件类型
            :limit : 最大允许上传个数
            :on-exceed : 文件超出个数限制时的钩子
            :on-preview : 点击文件列表中已上传的文件时的钩子

            :headers="Myhead" 设置上传头
          -->
          <el-upload
            
            list-type="picture-card"
            ref="upload"

          <el-dialog :visible.sync="dialogVisible">
            <img width="100%" :src="dialogImageUrl" alt="" />
          </el-dialog>

data中的对应属性

imageUrl: "",
      uploadUrl:  "http://localhost:8900/renren-fast/localUpload/uploadForType",

      uploadTemplateDialog: false,
      fileList: [],        
      uploadLoading: false,
      acceptFileType: "image/png, image/jpeg", // 设置上传文件类型
      downLoadLoading: "",

      dialogImageUrl: "",
      dialogVisible: false,

      showFileList: true,
7.2.1.2. 对应钩子函数放到methods里
// 文件超出个数限制时的钩子
    handleExceed(files, fileList) {
      this.$message.warning("只能选择1个文件!");
    },



    // 文件列表移除文件时的钩子
    handleRemove(file, fileList) {
      //console.log(file,fileList);
    },

    // 点击文件列表中已上传的文件时的钩子 ,  在 模态窗中显示
    handlePreview(file) {
      // console.log(file);
      console.log(file.url);
      this.dialogImageUrl = file.url;
      this.dialogVisible = true;
    },

    // 上传文件之前的钩子
    beforeUpload(file) {
      var that = this;
      // console.log("file:",file)
      //文件类型
      var fileName = file.name.substring(file.name.lastIndexOf(".") + 1);
      if ( !(fileName == "png" || fileName == "jpg"  || fileName == "jpeg") ) {
        that.uploadTemplateDialog = false;
        that.$message({
          type: "error",
          showClose: true,
          duration: 3000,
          message: "文件类型不是.png/.jpg文件!",
        });
        return false;
      }

      //读取文件大小
      var fileSize = file.size;
      // console.log(fileSize);
      if (fileSize > 1048576) {
        that.uploadTemplateDialog = false;
        that.$message({
          type: "error",
          showClose: true,
          duration: 3000,
          message: "文件大于1M!",
        });
        return false;
      }

      // 上传时 的 遮罩
      that.downloadLoading = that.$loading({
        lock: true,
        text: "数据上传中...",
        spinner: "el-icon-loading",
        background: "rgba(0,0,0,0.7)",
      });

     
      return true;
    },


    //文件上传成功时的钩子
    handleUploadSuccess(res, file) {
      // console.log(res)
      console.log("上传成功..." )

      // 用于在页面回显 图片
      try {
        this.imageUrl = file.raw;
      } catch (error) {
        this.imageUrl = window.URL.createObjectURL(file.raw);
      }

      // console.log("this.imageUrl ", this.imageUrl  )

      this.downloadLoading.close();
      this.uploadLoading = false;
      this.dataForm.brandLogoPath = res.path

      this.showFileList = true;

    },
7.2.1.3. 上传头信息

写在 计算函数里

computed: {
      Myhead: function () {
          return {token: this.$cookie.get('token')}
      }
  },
7.2.1.4. 回显

在 init 函数里 查看到 对应 的记录信息之后

this.fileList.pop();
   this.fileList.push({name:  this.dataForm.brandLogoPath, url:  this.dataForm.brandLogoPath });
7.2.1.5.后台处理

常量 配置

public class Const {

    /**
     * 本地存储 文件所在的路径
     */
    public static final String UPLOAD_LOCAL_PATH = "D:/upload/images/webshop/";

    /**
     * 本地存储 文件存储的路径
     */
    public static final String UPLOAD_LOCAL_PATH_WEB_URL = "http://127.0.0.1:8900/renren-fast/upload/";
}

在对应的controller中

@RequestMapping("/upload")
    @ResponseBody
    public R upload(@RequestParam("file") MultipartFile file) throws IOException {

        System.out.println("file => " + file.getOriginalFilename());
        if (file == null || file.isEmpty()) {
            System.out.println(" = " + "上传失败,请选择文件");
            return R.error("上传失败,请选择文件");
        } else {
            String path = FileUtils.saveFile(file);
            System.out.println("path = " + path);
            return R.ok().put("path", path);
        }
    }
    @RequestMapping("/uploadForType")
    @ResponseBody
    public R uploadForType(@RequestParam("type")String type, @RequestParam("file") MultipartFile file) throws IOException {

        System.out.println("type = " + type);
        System.out.println("file => " + file.getOriginalFilename());
        if (file == null || file.isEmpty()) {
            System.out.println(" = " + "上传失败,请选择文件");
            return R.error("上传失败,请选择文件");
        } else {
            String path = FileUtils.saveFileForType(file, type);
            System.out.println("path = " + path);
            return R.ok().put("path", path).put("type", type);
        }
    }

在 FileUtils 工具类中

/**
     * @description 文件上传,保存在本地硬盘,返回文件请求路径
     * @param picFile
     * @return
     * @throws IOException
     */
    /**/
    public static String saveFile(MultipartFile picFile) throws IOException {
        String location = null;
        String destName = "";
        if(!picFile.isEmpty()){
            //得到真实路径
            String fileName = picFile.getOriginalFilename();
            String kzm = fileName.substring(fileName.lastIndexOf("."));
            //要保存的文件名
            destName = UUID.randomUUID().toString()+kzm;
            //取得上传文件存储路径
            //File directory = new File("");// 参数为空
            //String path = directory.getCanonicalPath()+"/src/main/webapp"+Const.PIC_FILE;
            String path = Const.UPLOAD_LOCAL_PATH;
            //如果上传文件存储路径不存在则创建一个
            File s2 = new File(path);
            if (s2.exists()==false) {
                s2.mkdirs();
            }
            //文件路径
            location = path+"/"+destName;
            try {
                picFile.transferTo(new File(location));
            } catch (IllegalStateException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        String url = Const.UPLOAD_LOCAL_PATH_WEB_URL + destName;
        return url;
    }

    /**
     * @description 文件上传,保存在本地硬盘,返回文件请求路径
     * @param picFile
     * @return
     * @throws IOException
     */
    /**/
    public static String saveFileForType(MultipartFile picFile, String type) throws IOException {
        String location = null;
        String destName = "";
        if(!picFile.isEmpty()){
            //得到真实路径
            String fileName = picFile.getOriginalFilename();
            String kzm = fileName.substring(fileName.lastIndexOf("."));
            //要保存的文件名
            destName = UUID.randomUUID().toString()+kzm;
            //取得上传文件存储路径
            //File directory = new File("");// 参数为空
            //String path = directory.getCanonicalPath()+"/src/main/webapp"+Const.PIC_FILE;
            String path = Const.UPLOAD_LOCAL_PATH + type + "/";
            //如果上传文件存储路径不存在则创建一个
            File s2 = new File(path);
            if (s2.exists()==false) {
                s2.mkdirs();
            }
            //文件路径
            location = path+"/"+destName;
            try {
                picFile.transferTo(new File(location));
            } catch (IllegalStateException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        String url = Const.UPLOAD_LOCAL_PATH_WEB_URL + type + "/" + destName;
        return url;
    }

7.2.2.图片显示

在后台 的项目中 要增加

其中 Const.UPLOAD_LOCAL_PATH 为 文件存储的本地路径

@Configuration
public class WebMvcConfig implements WebMvcConfigurer {
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/upload/**").addResourceLocations("file:" + Const.UPLOAD_LOCAL_PATH);
    }
}

只要 实体类的属性值为 : http://127.0.0.1:8900/renren-fast/upload/brand_logo/3b73aaa7-ec21-4601-9432-ecabf07750d7.jpg

<template slot-scope="scope" >
          <img :src="scope.row.brandLogoPath"  style="width: 150px; height: 60px" />
        </template>

在 renren-fast 项目中

路径 : io.renren.config.ShiroConfig

由于 没有传递 token 还要 关闭 shiro的权限控制 ShiroConfig 类

filterMap.put("/upload/**", "anon");

7.3.下拉框

7.3.0.vue-template

<el-select v-model="value" placeholder="请选择">
    <el-option
      v-for="item in options"
      :key="item.value"
      :label="item.label"
      :value="item.value">
    </el-option>
  </el-select>

7.3.1. 准备数据

// 在data 中增加用于 迭代的数组
data () {
      return {
        options:[],
          ...
// 在 加载完成的钩子函数中 增加调用 
created() {
    this.oneDataList();
},
// 在methods里增加 获取信息的方法
oneDataList() {
    console.log("请求后台");
    this.dataListLoading = true;
    this.$http({
        url: this.$http.adornUrl("/base/categoryone/listAll"),
        method: "get",
    }).then(({ data }) => {
        console.log(data)
        if (data && data.code === 0) {
            this.options = data.list;
        } else {
            this.options = [];
        }
    });
},

7.3.2. 下拉组件

因为要 同时 保存 一级分类 的 id 和 name 所以 option 的 :value 有变化 , 同时 要结合 @change 事件

<el-select v-model="dataForm.coneName" placeholder="请选择一级分类" 
            @change="checkedOption"  value-key="coneId" >
     <el-option
                v-for="item in options"
                :key="item.coneId"
                :label="item.coneName +':' + item.coneId"
                :value="item"
                >
     </el-option>
</el-select>

7.3.3.封装数据

在methods 里 处理数据

// 改变 下拉框
checkedOption(item){
    this.dataForm.coneId = item.coneId
    this.dataForm.coneName = item.coneName
},

7.4.模态窗

通过 父子组件 + dialog 方式 完成

7.4.0.建立子组件

先在common下建立子组件 , 结构与 列表页相似

<template>
<!-- 模态窗-->
<el-dialog title="选择品牌"  width="80%"
      :close-on-click-modal="false"
      :visible.sync="visible"
    >

	<!-- 显示内容 -->    
    <el-form :inline="true" :model="whereForm" @keyup.enter.native="getDataList()">
      <el-form-item>
        <el-input    v-model="whereForm.key" placeholder="参数名" clearable></el-input>
      </el-form-item>
      <el-form-item>
        <el-button @click="getDataList()">查询</el-button>
      </el-form-item>
    </el-form>
    <el-table
      :data="dataList"
      border
      v-loading="dataListLoading"
      :highlight-current-row = "true"
      @current-change="handleCurrentChange"
      style="width: 100%;">


      <el-table-column
        prop="brandId"

            <a :href="scope.row.brandWebUrl"  target="_blank" >{{scope.row.brandWebUrl}}</a>
        </template>

          }
          this.dataListLoading = false
        })
      },
      // 每页数

      // 多选
      selectionChangeHandle (val) {
        this.dataListSelections = val
      },

    }
  }
</script>

7.4.1.引入组件

先引入这个el-dialog组件

import BrandDialog from "../common/brand-dialog";

根据具体的路径完成一个组件页面的引入,并且取名叫做BrandDialog ;

然后 声明组件的使用

components: { BrandDialog },

根据规则定义一个组件,按照驼峰的形式BrandDialog 转换成组件的名字,

在template标签里面添加一个组件

特别注意: 子组件标签 与 原来模版内容 要并列在 template 结点下,

但template 必须有唯一根结点

<brand-dialog
      v-if="brandDialogVisible"
      ref="brandDialog" ></brand-dialog>

通过 brandDialogVisible 值来 控制 显隐, 在data中 声明并赋初始值为false

// 品牌模态窗 显隐标识
  brandDialogVisible: false,

7.4.2.触发组件显示

增加元素, 触发的方法,

<el-form-item label="选择品牌" prop="brdId">
      <el-col :span="12">
            <el-input v-model="dataForm.brandCnName" placeholder="选择品牌" :disabled="true" ></el-input>
        </el-col>
        <el-col :span="6"  >
          <el-button type="success" round @click="openBrandDialog" >选择品牌</el-button >
        </el-col>
    </el-form-item>

添加对应的函数

/**
       * 打开 模态窗
       */
      openBrandDialog(){
          // 设置模态窗 显示
          this.brandDialogVisible = true;
          this.$nextTick(() => {
            // 调用 模态窗的初始化方法  
            this.$refs.brandDialog.init();
          });
      },

this.$nextTick()这是Vue生命周期中的钩子函数的其中之一,在显示的时候执行参数对应的函数,

然后就是this.$refs.brandDialog.init();使用this.$refs.组件名.组件方法(参数),

组件名称是在设定的时候通过ref="brandDialog"设定组件的名称变成refs的直接使用。

7.4.3.子组件数据

然后我们在组件里面,组件中的主体是在

<el-dialog title="选择品牌"  width="80%"
      :close-on-click-modal="false"
      :visible.sync="visible"
    >
    ... <!--数据显示 -->
    <span slot="footer" class="dialog-footer">
      <el-button @click="visible = false">取 消</el-button>
      <el-button type="primary" @click="selectedBrand()">确 定</el-button>
    </span>
 </el-dialog>

里面的,通过 :visible.sync="visible" 绑定一个boolean值来完成对于dialog的显示,

然后title完成对于弹窗的题目的设定,

然后展示init方法

/**
     * 初始化方法 ,  由父组件调用
     */
    init (id) {    
      this.visible = true
      this.$nextTick(() => {
          //调用查询数据的方法
        this.getDataList();
      })
    },

所有的 v-if 想要产生效果都需要设定默认值才能够使用
在这里具体逻辑就是this.visible = true;显示dialog,

然后就是 this.getDataList(); 查询列表数据

7.4.4.点击选中

在 data 声明用于记录选中信息

currentRow: null,

在 el-table 中增加 highlight-current-row 是否要高亮当前选中行

@current-change=“handleCurrentChange” 当表格的当前行发生变化的时候会触发该事件

<el-table
      :data="dataList"
      border
      v-loading="dataListLoading"
      :highlight-current-row = "true"
      @current-change="handleCurrentChange"
      style="width: 100%;">

对就的处理函数

handleCurrentChange(val) {
      // 将选中的行 赋值给  currentRow,  要先在 data中声明  
      this.currentRow = val;
    },

7.4.5.回传信息

点击 确定按钮 执行函数

/**
     * 选中 关闭模态窗
     */
    selectedBrand() {
      // console.log(this.currentRow)
      // 隐藏 模态窗
      this.visible = false;
      // 触发 父组件的事件, 将选中行信息传回
      this.$emit("selectedBrand", this.currentRow);
    },

7.4.6.父组件接值

在 组件引用里 加入

<brand-dialog
      v-if="brandDialogVisible"
      ref="brandDialog"

      @selectedBrand="selectedBrand"  ></brand-dialog>

@selectedBrand="selectedBrand"

等号 左边 与 子组件调用的方法相对应

等号 右边 是对应 父组件的函数

对应的函数, 接收到子组件传来信息, 并对dataForm 进行赋值

selectedBrand(brandData){
        console.log(brandData)
        this.dataForm.brdId = brandData.brandId;
        this.dataForm.brandCnName = brandData.brandCnName;
      },

7.5.树

7.5.1.vue页面

    <el-button v-if="draggable" @click="batchSave" >批量保存</el-button>

        });

      },
    }
   
  }
</script>

7.5.2.后台准备数据

后台 实体类 增加 子结点集合属性

@TableField(exist = false)
	private List<BaseAreaEntity> children;

后台controller 中 准备显示 树型数据

/**
     * 查询出所有的分类及子类, 以数形结构组装越来
     */
    @RequestMapping("/list/tree")
    public R listWithTree(){
        List<BaseAreaEntity> baseAreaTrees = baseAreaService.listWithTree();

        return R.ok().put("data", baseAreaTrees);
    }

serviceImpl中

@Override
    public List<BaseAreaEntity> listWithTree() {

        //1、查出所有分类
        List<BaseAreaEntity> allList = baseMapper.selectList(null);
        //2、组装成父子的树形结构
        //2.1)、找到所有的一级分类
        List<BaseAreaEntity> baseAreas = allList.stream()
                .filter(baseAreaEntity ->
                    baseAreaEntity.getAreaParId()==null
                )
                .peek((baseAreaEntity)->{
                    baseAreaEntity.setChildren(getChildrens(baseAreaEntity, allList));
                })
                .sorted((b1,b2)->{
                    return (b1.getAreaSort()==null?0:b1.getAreaSort()) - (b2.getAreaSort()==null?0:b2.getAreaSort());
                })
                .collect(Collectors.toList());

            return baseAreas;
    }

    //递归查找所有菜单的子菜单
    private List<BaseAreaEntity> getChildrens(BaseAreaEntity root, List<BaseAreaEntity> all){

        return all.stream()
                .filter(baseAreaEntity -> root.getAreaId().equals(baseAreaEntity.getAreaParId()))
                .peek(baseAreaEntity -> {
                    //1、找到子菜单
                    List<BaseAreaEntity> childrens = getChildrens(baseAreaEntity, all);
                    if (childrens != null && childrens.size()>0) {
                        baseAreaEntity.setChildren(childrens);
                    }
                })
                .sorted((b1,b2)->{
                    return (b1.getAreaSort()==null?0:b1.getAreaSort()) - (b2.getAreaSort()==null?0:b2.getAreaSort());
                })
                .collect(Collectors.toList());

    }

7.5.3.批量保存修改结点数据

controller中的方法

@RequestMapping("/update/sort")
    public R updateSort(@RequestBody BaseAreaEntity[] baseAreaEntities){
        System.out.println("Arrays.toString(baseAreaEntities) = " + Arrays.toString(baseAreaEntities));
        baseAreaService.updateBatchById(Arrays.asList(baseAreaEntities));
        return R.ok();
    }

7.6.联动

7.6.1.后台准备树形数据

@Override
    public List<Map<String, Object>> listCascader() {

        List<Map<String, Object>> list = categoryOneDao.selectList(null).stream()
                .map(categoryOneEntity -> {
                    Map<String, Object> oneMap = new HashMap<>();
                    oneMap.put("categoryId", categoryOneEntity.getConeId());
                    oneMap.put("categoryName", categoryOneEntity.getConeName());

                    List<CategoryTwoEntity> categoryTwoEntities = categoryTwoDao.selectList(
                            new LambdaQueryWrapper<CategoryTwoEntity>()
                            .eq(CategoryTwoEntity::getConeId, categoryOneEntity.getConeId()));

                    if (categoryTwoEntities != null && categoryTwoEntities.size()>0) {
                        List<Map<String, Object>> twoList = categoryTwoEntities.stream()
                                .map(categoryTwoEntity -> {
                                    Map<String, Object> twoMap = new HashMap<>();
                                    twoMap.put("categoryId", categoryTwoEntity.getCtwoId());
                                    twoMap.put("categoryName", categoryTwoEntity.getCtwoName());

                                    List<CategoryThreeEntity> categoryThreeEntitys = this.list(new LambdaQueryWrapper<CategoryThreeEntity>()
                                            .eq(CategoryThreeEntity::getCtwoId, categoryTwoEntity.getCtwoId()));

                                    if (categoryThreeEntitys != null && categoryThreeEntitys.size() > 0) {
                                        List<Map<String, Object>> thrList = categoryThreeEntitys.stream().map(categoryThreeEntity -> {
                                            Map<String, Object> thrMap = new HashMap<>();
                                            thrMap.put("categoryId", categoryThreeEntity.getCthrId());
                                            thrMap.put("categoryName", categoryThreeEntity.getCthrName());
                                            return thrMap;
                                        }).collect(Collectors.toList());
                                        twoMap.put("children", thrList);
                                    }
                                    return twoMap;
                                })
                                .collect(Collectors.toList());

                        oneMap.put("children", twoList);
                    }

                    return oneMap;
                })
                .collect(Collectors.toList());

        return list;
    }

其中 categoryId 为 id , categoryName 为 name , children 为子结点

7.6.2.页面组件

<el-cascader  style="width:280px;"
              filterable
              clearable 
              placeholder="试试搜索:手机"
              :props="cascaderProps"
              change-on-select
              :options="categoryOptions"        

              @change="handleChange"
              ref="cascader"
              v-model="categoryPath" >
</el-cascader>

data 增加

categoryOptions: [],
        cascaderProps:{
          value:"categoryId",
          label:"categoryName",
          children:"children"
        },
        categoryPath:[],

methods

handleChange(value) {
       console.log(value);   
     	// 在高版本中才有这样的方法
       console.log(this.$refs["cascader"].getCheckedNodes()[0].label)
       console.log(this.$refs["cascader"].getCheckedNodes()[0].pathLabels) //对应的label数组
 },

低版本可以在

for(let i=0; i<this.categoryOptions.length; i++ ){
            console.log( this.categoryOptions[i].categoryId )
            if(this.categoryOptions[i].categoryId == this.categoryPath[0]){
             
              this.dataForm.coneId = this.categoryOptions[i].categoryId
              this.dataForm.coneName = this.categoryOptions[i].categoryName
              for(let l=0; l<this.categoryOptions[i].children.length; l++){
                  if(this.categoryOptions[i].children[l].categoryId == this.categoryPath[1]){
                    this.dataForm.ctwoId = this.categoryOptions[i].children[l].categoryId
                    this.dataForm.ctwoName = this.categoryOptions[i].children[l].categoryName
                    for(let k=0; k<this.categoryOptions[i].children[l].children.length; k++){
                        if(this.categoryOptions[i].children[l].children[k].categoryId == this.categoryPath[2]){
                          this.dataForm.cthrId = this.categoryOptions[i].children[l].children[k].categoryId
                          this.dataForm.cthrName = this.categoryOptions[i].children[l].children[k].categoryName
                        }
                    }
                  }
              }
            }
        }

        console.log("data:", this.dataForm)

7.7.时间,日历

7.7.1.时间信息

Date.now() 取当前时间

原始格式 : 2018-10-30T10:06:20.000Z

new Date(this.xxDate).getTime() 转化为时间戳

7.7.2.按格式 显示 时间

<el-table-column
        prop="supplierFoundedDate"
        header-align="center"
        align="center"
           :formatter="dateFormat"
        label="成立时间">
      </el-table-column>

对应 函数

dateFormat(row,column){    
       var dT = new Date(row.supplierFoundedDate);//row 表示一行数据, supplierFoundedDate 表示要格式化的字段名称
       return dT.getFullYear()+"-"+(dT.getMonth()+1)+"-"+dT.getDate();
     },

7.7.3.日历插件

<el-date-picker
          v-model="dataForm.supplierFoundedDate"
          type="date"
          placeholder="选择成立时间">
        </el-date-picker>

可能是时区等原因, 返回原始格式 : 2018-10-30T10:06:20.000Z, 传递后台 不能成功转换成java.util.Date() 会报错
可以通过 new Date(this.dataForm.supplierFoundedDate).getTime() 转化为时间戳 来 解决

7.8.表格扩展

在 列表 页面的 el-table 中加入

<el-table-column fixed type="expand">
      <template slot-scope="props">
        <el-form label-position="left" inline class="demo-table-expand">
          <el-form-item label="银行名称:">
            <span>{{ props.row.bankName }}</span>
          </el-form-item>
          <el-form-item label="银行账号:">
            <span>{{ props.row.bankSn }}</span>
          </el-form-item>

          <el-form-item label="地址:" style="width: 100%" >
            <span>{{ props.row.supplierAddress }}</span>
          </el-form-item>
          <el-form-item label="描述:" style="width: 100%" >
            <span>{{ props.row.supplierInfo }}</span>
          </el-form-item>
        </el-form>
      </template>
      </el-table-column>

7.9.富文本

7.9.1.tinymce

下载 地址 : https://www.tiny.cloud/get-tiny/self-hosted/

语言包 地址: https://www.tiny.cloud/get-tiny/language-packages/

# 安装
npm install tinymce -S


# vue2.0版本应该使用
npm install --save "@tinymce/tinymce-vue@^3"


# vue3.0版本应该使用
npm install --save "@tinymce/tinymce-vue@^4"


# 再运行 
npm install tinymce -S

安装之后,在 node_modules 中找到 tinymce/skins 目录,然后将 skins 目录拷贝到 static 目录下

结构 如:
static

tinymce

skins

zh_CN.js

在页面中引入以下文件

import tinymce from 'tinymce/tinymce'
import 'tinymce/themes/silver/theme'
import Editor from '@tinymce/tinymce-vue'

import 'tinymce/icons/default/icons';
import 'tinymce/plugins/image';
import 'tinymce/plugins/media';// 插入视频插件
import 'tinymce/plugins/table';// 插入表格插件
import 'tinymce/plugins/lists';// 列表插件
import 'tinymce/plugins/wordcount';// 字数统计插件

tinymce-vue 是一个组件,需要在 components 中注册,

components: { Editor },

然后直接使用

<Editor id="tinymce" v-model="tinymceHtml" :init="editorInit"></Editor>

编辑器需要一个 skin 才能正常工作,所以要设置一个 skin_url 指向之前复制出来的 skin 文件

在data 中配置初始化属性

editorInit: {
    language_url: '/static/tinymce/zh_CN.js',
    language: 'zh_CN',
    skin_url: '/static/tinymce/skins/ui/oxide', // skin路径
    height: 300, // 编辑器高度
    branding: false, // 是否禁用“Powered by TinyMCE”
    menubar: true, // 顶部菜单栏显示
    plugins: this.plugins,
    toolbar: this.toolbar,
}

同时在 mounted 中也需要初始化一次:

mounted (){
	tinymce.init({});
},

如果在这里传入上面的 init 对象,并不能生效,但什么参数都不传也会报错,所以这里传入一个空对象

完成了上面的初始化之后,就已经能正常运行编辑器了,但只有一些基本功能

tinymce 通过添加插件 plugins 的方式来添加功能

比如要添加一个上传图片的功能,就需要用到 image 插件,添加超链接需要用到 link 插件

<template>
  <div class='tinymce'>
    <h1>tinymce</h1>
    <editor id='tinymce' v-model='tinymceHtml' :init='init'></editor>
    <div v-html='tinymceHtml'></div>
  </div>
</template>

<script>
import tinymce from 'tinymce/tinymce'
import 'tinymce/themes/silver/theme'
import Editor from '@tinymce/tinymce-vue'
import 'tinymce/plugins/image'
import 'tinymce/plugins/link'
import 'tinymce/plugins/code'
import 'tinymce/plugins/table'
import 'tinymce/plugins/lists'
import 'tinymce/plugins/contextmenu'
import 'tinymce/plugins/wordcount'
import 'tinymce/plugins/colorpicker'
import 'tinymce/plugins/textcolor'
    
export default {
  name: 'tinymce',
  data () {
    return {
      tinymceHtml: '请输入内容',
      init: {
          language_url: '/static/tinymce/zh_CN.js',
          language: 'zh_CN',
          skin_url: '/static/tinymce/skins/ui/oxide', // skin路径
          content_css:'/static/tinymce/skins/content/default/content.css',
          height: 300, // 编辑器高度
          branding: false, // 是否禁用“Powered by TinyMCE”
          menubar: true, // 顶部菜单栏显示
          font_formats: '微软雅黑=Microsoft YaHei,Helvetica Neue,PingFang SC,sans-serif;苹果苹方=PingFang SC,Microsoft YaHei,sans-serif;宋体=simsun,serif',
          fontsize_formats:'12px 14px 16px 18px 20px 22px 24px 26px 28px 30px 32px 34px 36px 38px 40px 50px 60px 70px 80px 90px 100px 120px 140px 160px 180px 200px',
          plugins: 'link lists image code table colorpicker textcolor wordcount contextmenu',
          toolbar:'bold italic underline strikethrough | fontsizeselect | forecolor backcolor | alignleft aligncenter alignright alignjustify | bullist numlist | outdent indent blockquote | undo redo | link unlink image code | removeformat',
      }
    }
  },
  mounted () {
    tinymce.init({})
  },
  components: {Editor}
}
</script>

但是当富文本在某一个弹窗上使用时,

工具栏会出现下拉选择时的层级比弹窗的小,所以,选项会被弹窗遮挡。

而解决这个问题,需要把工具栏的下拉框的层级提高,

找到static/tinymce/skins/ui/oxide/skin.min.css文件

把class名为tox-tinymce-aux的第一个的z-index属性变大即可

tinymce 在初始化的属性对象中( init对象中 )提供了 images_upload_url 等 api 让用户配置上传图片的相关参数

但为了在不麻烦后端的前提下适配自家的项目,还是得用 images_upload_handler 来自定义一个上传方法

images_upload_handler: (blobInfo, success, failure) => {
       // const img = 'data:image/jpeg;base64,' + blobInfo.base64();
      // success(img);
       this.handleImgUpload(blobInfo, success, failure);
     }

这个方法会提供三个参数:blobInfo, success, failure

其中 blobinfo 是一个对象,包含上传文件的信息

successfailure 是函数,上传成功的时候向 success 传入一个图片地址,失败的时候向 failure 传入报错信息

handleImgUpload (blobInfo, success, failure) {
      // 上传的文件信息
        let fd = new FormData();
        fd.append("file", blobInfo.blob());
        fd.append("type","tinymec")
        this.$http({
          url: this.$http.adornUrl(
            "/localUpload/uploadForType" 
          ),
          method: "post",
          data: fd,
          headers: {
            "Content-Type":
              "multipart/form-data;boundary=" + new Date().getTime(),
            "token": this.$cookie.get('token')
          },
        }).then(({ data }) => {
          if (data && data.code === 0) {
            this.$message({
              message: data.path + ",操作成功",
              type: "success",
              duration: 1500,
              onClose: () => {
                 success(data.path)
              },
            });
          } else {
            failure('error')
          }
        });
}
