      elem: '#upload',
      url: '{:U("addTL")}',
      auto: false,//选择文件后不自动上传
      bindAction: '#commit',
      //上传前的回调
      before: function () {
        this.data = {
          name: $('input[name="name"]').val()
        }
      },

          $('#preview').attr('src', result);
        })
      },
      //操作成功的回调
      done: function (res, index, upload) {
        var code = res.code === 0 ? 1 : 2;
        layer.alert(res.msg, {icon: code}, function () {
          parent.window.location.reload();
        })
      },
      //上传错误回调
      error: function (index, upload) {
