使用vant-uploader上传照片无法删除的解决

    deleteItem: function (event) {
      var index = event.currentTarget.dataset.index;
      this.$emit(
        'delete',
        __assign(__assign({}, this.getDetail(index)), {
          file: this.data.fileList[index],
        })
      );
    },

    <van-uploader catch:delete="deleteImg" preview->      
    </van-uploader>

  deleteImg(event){
    let index= event.detail.index
    console.log(index)//输出的就是图片所在fileList的下标，自己根据需要进行操作就行
  },

<van-uploader :before-read="beforeRead" ：after-read="afterRead" />
export default {
  methods: {
    beforeRead(file) {
      if (file.type !== 'image/jpeg') {
        Toast('请上传 jpg 格式图片');
        return false;
                    }
      return true;
              },
   afterRead(file) {
      // 此时可以自行将文件上传至服务器
      console.log(file);
              },
          },
};

function delImg(index){
let ind = vue.$data.imgContList.indexOF(index);
vue.$data.imgContList.splice(ind,1);
console.log(vue.$data.imgContList);
let delUploader =document/getElementByClassName("van-uploader__preview-delete");
for(let i=0;i<vue.$data.imgContList.length;i++){
$(delUploader[i]).removeAttr("id").attr("id","removeClose_4_"+(vue.$data.imgCountList[i]));
$(delUploader[i]).removeAttr("onclick").attr("onclick","delImg("+(vue.$data.imgCountList[i])+")");
}
}
