how can I retrieve an html document from a url from javascript?

问题

I have a url and I want to retrieve the html dom generated when going to the url (all the code for the page) in a javascript variable.

How can I do this? I'm guessing an html get or post? Can anyone give an example with jQuery?

Every time I do a $.get or $.post like this:

$.get("http://www.google.ca", function(result) { alert(result); alert($(result).html()); });

$.post("http://www.google.ca", function(result) { alert(result); alert($(result).html()); }, "xml");

the first alert in each call comes up blank and the second comes up as null. Any ideas?

Thanks,
Matt

You can only fetch documents (in this way) from your own domain due to the same origin policy.

$("#divId").load("documentname.html");
