iview Upload组件多个文件上传的示例代码

　　　　　　 //创建 formData 对象          let formData = new FormData();          //向 formData 对象中添加文件--这是其他参数          formData.append('jsid', _jsid);          //多个文件上传----------重点----需要吧已经存储到本地的文件加入 formData所以这里用for循环          for(var i=0; i< that.file.length; i++){            formData.append("uploadFile",that.file[i]);  // 文件对象            }
