AJAX 页面下载进度 [英] AJAX Page Download progress

问题描述

我想了解我的 AJAX 请求的进度 - 到目前为止已经下载了多少文件.例如，我正在使用 AJAX 下载一张大图片，因此我可以将内容放在 DATA url 中(这可能不是最好的方法，这只是一个示例.)

I want to get the progress of my AJAX request - how much has been downloaded so far out of how much the file is. For example, I am downloading a large picture with AJAX so I can put the content in a DATA url (this may not be the best way to do that, it's just a example.)

因此，我向某个我无法控制的主机 (flickr) 发出 AJAX 请求，并将进度报告给用户.如果没有服务器端脚本或类似的东西，我无法找到一种方法来做到这一点.最好的解决方案是使用 JQuery，因为这是我在我的网站上使用的.谢谢！以撒

So, I make the AJAX request to some host I have no control over (flickr), and report the progress back to the user. I cannot find a way to do this without a server-side script or something like that. Preferably the solution would use JQuery, because that is what I use for my website. Thanks! Isaac

推荐答案

据我所知，$.ajax() 函数不支持加载字节数".它只有开始和完成事件，没有进度事件.

As far as I know, the $.ajax() function has no support for "bytes loaded". It only has start and complete events, no progress event.

我发现 这个线程 详细说明了一次尝试，但显然该代码适用于多种浏览器，但不适用于 IE.他们提出的建议是在其他浏览器中显示进度，并为 IE 显示一条简单的正在加载..."消息.

I found this thread detailing an attempt, but apparently the code works in several browsers but not IE. The suggestion they make is to show progress in other browsers, and a simple "loading..." message for IE.
