jQuery find all elements with class beneath parent, even in children elements
提问by Ben
Here is some sample HTML:
下面是一些示例 HTML:
<div class="parent">
<div class="searchEl"></div>
<div class="searchEl"></div>
<div class="child">
<div class="searchEl"></div>
<div class="searchEl"></div>
</div>
</div>
And here is a jQuery function:
这是一个 jQuery 函数:
$(function(){
$(".parent>.searchEl").each(function(){
$(this).html("Found this one");
});
});
The DOM elements will end up like so:
DOM 元素将像这样结束:
<div class="parent">
<div class="searchEl">Found this one</div>
<div class="searchEl">Found this one</div>
<div class="child">
<div class="searchEl"></div>
<div class="searchEl"></div>
</div>
</div>
Using jQuery/Javascript, how can I search for and find all the elements with class .searchEl
beneath the element .parent
, even if they are within another child element, without searching the document globally with $(".searchEl")
?
使用 jQuery/Javascript,我如何搜索和查找元素.searchEl
下方具有 class 的所有元素.parent
,即使它们位于另一个子元素中,而无需使用 全局搜索文档$(".searchEl")
?
