如何显示的装载图形，而一个文件是越来越上传？
问题描述：
该文件应在上传通过Ajax或内部框架的背景。我应该可以用JavaScript来检测时，上传完成后，这样我就可以隐藏加载图形和用户重定向到一个新的URL。使用jQuery是罚款。
The file should be uploaded in the background via Ajax or Iframes. I should be able to detect via javascript when the upload has completed, so I can hide the loading graphic and redirect the user to a new URL. Using Jquery is fine.
答
Check out jQuery Uploadify
编辑：也有一个类似的问题：how-to-upload-file-jquery - 你可以显示图形的上传按钮被点击并隐藏在成功后/ onError的回调函数
