推荐答案
（document）.ready（function（）{
(document).ready(function () {
（'＃fileupload'）。fileupload（{
dataType：'json'，
url：'〜/ Clr / UploadFiles '，
autoUpload：true，
done：function（e，data）{
('#fileupload').fileupload({
dataType: 'json',
url: '"~/Clr/UploadFiles',
autoUpload: true,
done: function (e, data) {
（'。file_name ）的.html（d ata.result.name）;
('.file_name').html(data.result.name);
