var files = this.files = obj.pushFile(); //将每次选择的文件追加到文件队列

//单个重传

//删除

});

});
}, before: function (obj) {

this.data.Description = $("#Description").val();
}
, done: function (res, index, upload) {
debugger;
if (res.code == 200) { //上传成功
var tr = demoListView.find('tr#upload-' + index),
tds = tr.children();
tds.eq(2).html('<span style="color: #5FB878;">上传成功</span>');
tds.eq(3).html(''); //清空操作

}
this.error(index, upload);
}
, error: function (index, upload) {
debugger;
var tr = demoListView.find('tr#upload-' + index)
, tds = tr.children();
tds.eq(2).html('<span style="color: #FF5722;">上传失败</span>');
tds.eq(3).find('.test-upload-demo-reload').removeClass('layui-hide'); //显示重传
}
});
});
暂时就找到这样解决,如你有更好方法,欢迎留言交流。
