jQuery: Get HTML including the selector?

问题

Say I have this HTML:

<ul>
  <li id="example"><strong>Awesome</strong> example text</li>
</ul>

I want to be able to do something like $('#example').html() but right now doing that obviously only gets <strong>Awesome</strong> example text.

So how can I get the HTML including the selected element?

ie. <li id="example"><strong>Awesome</strong> example text</li>

I'm using jQuery 1.4.4.

回答1:

In this specific case:

var outerHTML = $("<div />").append($('#example').clone()).html();

See this page for more details.

And the discussion here: http://api.jquery.com/html/ (this explains that this isn't in jQuery core and why some logical solutions won't work)

回答2:

You could try this:

var html = $('<div>').append($('#example').clone()).html();

回答3:

For browsers that support it, outerHTML can do that. There are jQuery plugins like this and this that enable support via some clever jQuery.

回答4:

var outerHtml = $('#example').detach();

回答5:

Anything wrong with simply using $('#example') ? This grabs the whole thing!
