//      获取当前index
getImageTypeIndex:function (index) {this.uploadImageType = index  //先在data里定义下，此处省略定义},



 //      图片上传成功
getImageSuccess:function (res, file) {
        this.$message({
          message: &#39;上传成功！&#39;,
          type: &#39;success&#39;
        });
　　　　　this.list[this.uploadImageIndex].imageUrl = res.data.fileId   //我这里是list里有 imageUrl 来存储图片id,展示的地方根据id自己拼url
 },
