jQuery.get(window.location.href, function(data) {
alert(data);
alert($(data).html());
});
The first popup is all the HTML good and healthy.
The second popup is blank. Why? (the HTML is XHTML compliant)
回答1:
From the documentation:
The HTML string cannot contain elements that are invalid within a div, such as html, head, body, or title elements.
If you are fetching a complete HTML document, then you will have lots of elements that may not appear in a div.
回答2:
Because it will return a string with all the HTML. data isn't a jQuery object.

I tried this on my PC. You get back the following:
"
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head id="Head1"><title>
</title><link href="App_Themes/selectors.css" rel="stylesheet" type="text/css" /></head>................etc
This will not parse into a jQuery obejct. You get needs to be on a server-side script page that will explicitly output HTML.
I suppose if you really need an item in the HTML then you can strip it out from the text using the built-in string methods.

Change your code to something like this
$('#yourContainingDiv').html(data);
The html in data will be placed in the div tag
