如何检测，谷歌即时页面已完全加载？ [英] How to detect that Google Instant page has loaded completely?

问题描述

我工作的一个浏览器插件（想想 SEOQuake ） - 我需要显示在搜索结果的一些数据显示

I'm working on a browser extension (think SEOQuake) - I need to display some data about the search results that are shown.

问题：如果有什么事情被添加到谷歌即时搜索结果页，同时它还是在被加载的过程中，它会覆盖任何补充。我抓住了自己写一些非常靠不住的setInterval业务（等待，直到 OL＃的内容RSO 停止大小发生变化，类似的东西），所以我想这意味着我不知道如何可靠地确定页面加载完成。

Issue: If anything is added to the Google Instant results page while it's still in the process of being loaded, it'll overwrite any additions. I caught myself writing some really wonky setInterval business (waiting until the contents of ol#rso stop changing in size, stuff like that) so I suppose that means I'm not sure how to reliably determine if the page is done loading.

我的可以的只是它等待1-2秒，但我真的要开始获取数据，一旦结果被加载，以节省时间最高金额。

I could just have it wait 1-2 seconds but I really want to start fetching the data as soon as the results are loaded to save maximum amount of time.

编辑：请记住，我不能使用DOMElementWhatever因为IE8不支持它

Keep in mind, I can't use DOMElementWhatever because IE8 doesn't support it.

推荐答案

试试这个：

window.addEventListener("message", function(e) {if(e.data == 'jrc') console.log('loaded')}, false);

这应该工作在IE 8+和所有其他浏览器： http://caniuse.com /＃壮举= X-DOC-消息

That should work in IE 8+ and all other browsers: http://caniuse.com/#feat=x-doc-messaging

如果没有在IE 8的工作（不能在我的Mac测试在现在），让我知道。我相信，我在最后一小时的rs.js一些相当不错的理解。 ;）

If that doesn't work in IE 8 (can't test in on my Mac right now), let me know. I believe I got some reasonably good understanding of the rs.js in the last hour. ;)
