示例如下
[code]
[/code]
$(‘div’).filter(‘.elephants’); // <-- selects the second div, because it has class="elephants"$('div').find('.elephants'); // <-- selects the first paragraph, because it has class="elephants"* Note that these two examples are very simple and would probably be better written as ...$('div.elephants');... and ...$('div .elephants');
