AJAX progress bar dispaying loading progress percentage for page load
提问by Josh
How do you use a progressbar to show the loading percentage for a page? ...(similar to how they show in flash)
如何使用进度条显示页面的加载百分比？...（类似于它们在 flash 中的显示方式）
Thanks
谢谢

Impossible(on IE8 & FF3 & Opera without plugin or extension). If you want real loading percentage include HTML + Javascript + Stylesheet + Image. you can only detect how many file loaded to page(only Image & javascript can be detected by this technique).
不可能（在没有插件或扩展的 IE8 & FF3 & Opera 上）。如果你想要真正的加载百分比包括 HTML + Javascript + 样式表 + 图像。您只能检测加载到页面的文件数量（此技术只能检测图像和 javascript）。

I would say that if you need a progressbar for a page, that page might need some rethinking.
我想说的是，如果您需要一个页面的进度条，那么该页面可能需要重新思考。
Personally I don't like pages that have progress bars (Like the one in the ASUS Download Area). They are just annoying. My browser already have a progressbar. And I would like my bandwidth to be used to download the page and not graphics that would just tell me that I am still waiting for the page.
我个人不喜欢有进度条的页面（比如华硕下载区中的那个）。他们只是烦人。我的浏览器已经有一个进度条。我希望我的带宽用于下载页面，而不是那些只会告诉我我仍在等待页面的图形。
When it comes to AJAX requests ON a page though, I would just use a spinner thing of some sort. To tell the user that something is going on and that the page is not dead. And again, if the background request takes so long that you would need a progressbar, I would again say that the background request should maybe be rethought.
不过，当涉及到页面上的 AJAX 请求时，我只会使用某种微调器。告诉用户某些事情正在发生并且页面没有死。再一次，如果后台请求花费的时间太长以至于您需要一个进度条，我会再次说后台请求可能应该重新考虑。
