   getBanner() {
      detailBanner(this.$route.params.bannerCode)
        .then(res => {
          this.formValidate.bannerCode = res.data.data.bannerCode;
          this.formValidate.bannerTitle = res.data.data.bannerTitle;
          this.formValidate.bannerText = res.data.data.bannerText;
          this.url = res.data.data.url;
          let urlHttps = this.url.slice(0, 5);   //https
          let urlHttp = this.url.slice(0, 4);    //http
          this.select2 = this.url.substr(-4);    //截取后4位字符串
          //进行判断，判断url 的头是http 还是https
          if (urlHttps == "https") { 
              //给左边的选择器赋值
              this.select1="https://";
              //给中间部分赋值
              var length = this.url.length-12;
              this.formValidate.url=this.url.substr(8,length)
          }else if (urlHttp == "http") {
             //给左边的选择器赋值
              this.select1="http://";
              var length1 = this.url.length-11;
              //给中间部分赋值
              this.formValidate.url=this.url.substr(7,length1);
          }
          this.formValidate.bannerType = res.data.data.bannerType + "";
          this.formValidate.startDate = res.data.data.startDate;
          this.value1=res.data.data.startDate;
          console.log(this.formValidate.startDate);
          this.formValidate.images = res.data.data.images;
          let im = res.data.data.images.split(",");
          im.map(imss => {
            this.uploadList.push({
              status: "finished",
              response: {
                data: {
                  url: imss
                }

            });
          });
        })
