效果

导入组件

import ElImageViewer from "element-ui/packages/image/src/image-viewer";
components:{ ElImageViewer },

模板使用组件

<el-image-viewer
      v-if="isShowPics"
      :on-close="closeViewer"
      :url-list="srcList"
    />

定义两个变量

isShowPics:false,
   srcList:[],

在v-html添加点击获取图片

<div v-html="newsForm.content" @click="getImg($event)" style="padding-left: 50px;padding-right: 50px;"></div>

两个点击事件,包含预览时滚动异常

closeViewer(){
      this.isShowPics = false
      this.srcList = []
      move()
      //取消滑动限制
      function move(){
        var mo=function(e){
          e.preventDefault();
      };
      document.body.style.overflow='';//出现滚动条
      document.removeEventListener("touchmove",mo,false);
    }
    },
    getImg($event){
      let currentSrc=$event.target.currentSrc
      if (currentSrc){
        this.srcList = [currentSrc]
        this.isShowPics = true
        stop()
      }
        //禁止滚动
      function stop(){
        var mo=function(e){
          e.preventDefault();
        };
        document.body.style.overflow='hidden';
        document.addEventListener("touchmove",mo,false);//禁止页面滑动
      }
    },
