Description: Return the number of DOM elements matched by the jQuery object.
<ul> <li>foo</li> <li>bar</li> </ul>
We can determine the number of list items by calling .size()
:
alert('Size: ' + $('li').size());
This will alert the count of items:
Size: 2
The .length property is a slightly faster way to get this information.
