[英]jQuery get first children of element
here is my html这是我的 html
<div class="start">
<div> <!-- this -->
<div></div>
</div>
<div></div> <!-- this -->
<div> <!-- this -->
<div>
<div></div>
</div>
<div>
<div>
I need to collect all the selected div
, and I can do it with $('div[class="start"] > div')
, but how to do it in a .each()
cycle, because I'm cycling on all the div[class="start"]'
.我需要收集所有选定的
div
,我可以用$('div[class="start"] > div')
来完成,但是如何在.each()
循环中完成,因为我正在骑自行车所有div[class="start"]'
。
$('div[class="start"]').each(function(){
doSomething($(this));
//this below is what I want to achieve
$(this).children('> div').each(function(){
doSomethingElse($(this));
});
});
Use children
使用
children
$('div.start').children().each(function() {
This will select all the direct children of the div
having class start
.这将选择具有 class
start
的div
所有直接子级。
There is no need of using attribute-value selector here, you can use class selector.这里不需要使用属性值选择器,你可以使用类选择器。
You just need to remove >
or > div
你只需要删除
>
或> div
$('div[class="start"]').each(function(){
doSomething($(this));
//this below is what I want to achieve
$(this).children().each(function(){
doSomethingElse($(this));
});
});
Your code is more or less correct but instead of children() you need to use find()您的代码或多或少是正确的,但您需要使用 find() 而不是 children()
$('div[class="start"]').each(function(){
doSomething($(this));
//this below is what I want to achieve
$(this).find('> div').each(function(){
doSomethingElse($(this));
});
});
