 layui.use(upload, function () {
    var upload = layui.upload;

    upload.render({
      elem: #LAY_avatarUpload
      , url: setter.apiDomain + /api/WxPay/UploadFileByStream_Head
      , choose: function (obj) {
        //将每次选择的文件追加到文件队列
        var files = obj.pushFile();

        //预读本地文件,如果是多文件,则会遍历。(不支持ie8/9)
        obj.preview(function (index, file, result) {
          console.log(index); //得到文件索引
          console.log(file); //得到文件对象
          console.log(result); //得到文件base64编码,比如图片

          //obj.resetFile(index, file, ‘123.jpg‘); //重命名文件名,layui 2.3.0 开始新增

          //这里还可以做一些 append 文件列表 DOM 的操作

          //obj.upload(index, file); //对上传失败的单个文件重新上传,一般在某个事件中使用
          //delete files[index]; //删除列表中对应的文件,一般在某个事件中使用
        });

      }
      , done: function (index, res) {
        //上传完毕回调
        if (index.Data.Url != "") {
          var url = index.Data.Url;
          $(".UserHeadImgUrl").attr(src, setter.apiDomain + url);
        }
        var UserHeadImgUrl = $(.UserHeadImgUrl).attr("src");
        var url = /api/Userinformation/EditImg;                  ----这个主要就是更改字段,就没粘上来
        var parment = {
          UserHeadImgUrl: UserHeadImgUrl
        }
        callpack = function ()
        {

        }
        admin.ajax(url, parment, callpack)
      }
      , error: function (index) {
        //请求异常回调
      }
    });
  })
