count objects in javascript

I have a little js problem and thought this wonderfull community would be able to help me!

Let's say I want to find all $('footer') elements and I want to know if there is either 1 or 2 footers on the page. How would I do that?

using length() or s开发者_如何学编程omething similar?

Thanks a lot for your help :)

Use the length^[docs] property.

$('footer').length;

Please see the jQuery docs.

They're really very good, and typing length into the search field would dynamically bring the solution to you.

Or use the .size() function - see jquery docs

$('footer').size();

You can of course just use:

document.getElementsByTagName('footer').length;

But footer is an HTML5 element, many browsers in use do not support it yet.
