js / jquery / html：从iframe获取div

Question

How can I grab a div from an iframe into a JS variable? Doesn't necessarily have to use jQuery.

Answer 1

document.getElementById('IframeId').contentWindow.document.getElementById('DivId');

Answer 2

In jQuery syntax, that would be $('iframe').contents().find('div') . (Substitute any specific ids/classes/other selectors you need, of course). Tracker1's answer should work fine for standard Javascript.
