$.get("www.google.com", function(data){

推荐答案

不，jQuery 不能直接访问通过 XmlHttpRequest 加载的页面的 DOM.为此，您必须使用用 JavaScript 编写的 HTML 解析器，例如 John Resig 写的那个.不过，这仍然比您预期的要困难得多.

Nope, jQuery can't directly access the DOM of a page that was loaded via an XmlHttpRequest. In order to do this, you would have to use an HTML parser written in JavaScript, like the one that John Resig wrote. It's still a much harder task than you were probably expecting though.
