富文本组件上传图片及回显图片

上传：

   watch: {
      content(val) {
        this.setBaseImg(val);
      },
    },
save(){
this.updataImg();
this.ruleForm.activityContent = this.content;//this.ruleForm.activityContent要传给后端的参数
}

//把路径转成key
      updataImg() {
        let content = this.content;
        var self = this;
        let imgReg = /|\/>)/gi // 匹配图片中的img标签
        let srcReg = /src=[\'\"]?([^\'\"]*)[\'\"]?/i // 匹配图片中的src
        let arr = content.match(imgReg) // 筛选出所有的img

        if (arr != null) {

          for (let i = 0; i < arr.length; i++) {
            let src = arr[i].match(srcReg)
            // 获取图片地址判断是否是base64格式

            if (src[1].indexOf('https://') != -1) {
              var a = src[1].split('?')[0].split('https://oilpay-test.oss-cn-shanghai.aliyuncs.com/')[1];
              self.content = self.content.replace(src[1], a);
            }
          }
        }
      },

回显：

created(){
this.$http.post("",data).then(res=>{//请求后端接口获取回显数据
           this.content = res.data.activityContent;
          this.list1 = [res.data];
          this.listInit();
}


 // list初始化
      listInit(content) {

          let contents = this.list1[j].activityContent;
          let imgReg = /|\/>)/gi // 匹配图片中的img标签
          let srcReg = /src=[\'\"]?([^\'\"]*)[\'\"]?/i // 匹配图片中的src
