停止浏览器＆QUOT;活动指示器厄运＆QUOT的;在加载彗星/服务器推送iframe中 [英] Stop the browser "throbber of doom" while loading comet/server push iframe
问题描述
在使用彗星或Ajax的龙拉技术 - 一个iframe通常使用。虽然该iframe等待漫长的连接关闭，浏览器正在旋转的活动指示器（进度/加载指示器）。
When using Comet, or Ajax Long Pull techniques - an iframe is usually used. And while that iframe is waiting for the long connection to close, the browser is spinning its throbber (the progress/loading indicator).
一些网站，例如etherpad.com，设法使它停止。
Some websites, for example etherpad.com, managed to make it stop.
他们怎么办呢？
推荐答案
挖了一天，并在网际网路的胆量一晚，这里以后就是我想出了：
After digging for a day and a night in the guts of the internets, here is what I came up with:
-
服务器发送的事件 - 非常酷，目前仅在Opera，但可能是HTML5的一部分，其他浏览器有时可能支持它。添加新的元素标签与内容类型应用程序/ x-DOM事件流的，它允许服务器可在客户端DOM 触发事件。它不应该显示进度指示器，据我了解。这也是一个标准的工作草案，而不是像整个IFRAME彗星事情黑客攻击。
server-sent events - Very cool, currently works only in Opera, but may be part of HTML5 and other browsers may support it sometime. Adds a new element tag with content-type of "application/x-dom-event-stream" which allows the Server to fire events in the Client DOM. And it should not show a progress indicator, as far as I understand. It's also a working draft of a standard, and not a hack like the whole iframe comet thing.
XMLHtt prequest - 在Firefox和Safari浏览器，但不是在IE浏览器，它可用于长期拉动页面加载，使来处理，因为它们出现在每个readyStateChange事件片段。不会显示进度指示器*。 - 见下文
XMLHttpRequest - in Firefox and Safari, but not in IE, it can be used for long-pull page loading that enables to handle fragments as they appear on each readyStateChange event. Will not show progress indicator*. -- see comment below
的ActiveXObject（HTMLFILE） - 可在IE被用来创建一个页面/窗口是当前窗口范围之外。这使得进度指示器走开！加载的IFRAME将是一种无形的浏览器。
ActiveXObject("htmlfile") - can be used in IE to create a page/window that is outside of the current window scope. This makes the progress indicator go away! The loaded iframe will be in an invisible browser.
