javascript - jQuery 文件上传插件 - 开始/取消按钮和进度条不起作用

Question

在文档事件就绪时，问题是:

TypeError: this.element.find(...).find(...).each(...).end(...).find(...).button(...).end(...).find(...).button(...).end(...).find(...).button(...).end(...).find(...).progressbar is not a function

jquery.fileupload-jquery-ui.js 的第 114 行。

当我尝试输入一些东西时，我在控制台中有这样的东西:

TypeError: $this.find(...).find(...).progressbar is not a function

jquery.fileupload-jquery-ui.js的第45行

TypeError: node.find(...).empty(...).progressbar is not a function

jquery.fileupload-jquery-ui.js 的第 60 行

我注释掉了不包含 jquery.fileupload-jquery-ui.js 的行。上传文件与选项 autoUpload:true 一起工作正常。如果 autoUpload 为 false，则不会显示开始/取消按钮和进度条。

提示？

这些是我的图书馆:
