jquery的find的filter的区别
贝贝爸 发表在 技术文章 |filter will select a certain subset (zero or more) of the already
selected elements.
jquery的filter将在一组已经选取的元素里面选择
find will select a set of (zero or more) elements that are descendants
of the already selected elements.
jquery的find将在一组已经选取的元素的子节点里面选择
Here is an example:
示例如下
$(’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’);
