具有Div的元素具有特定的类名称 [英] Elements with a Div having a specific class name

问题描述

文档中有许多Div

$

 < div class =sample/> 
 .. 
< div class =sample/> 
 .. 
< div class =sample/> 
 .. 
< div id =samplediv> 
< div class =sample> 
< div> 
< / div> 
  

我的问题是通过类示例找到div并处理该div的一些属性。所以我想用class =sample来获得Div吗？

通过类名使用函数：

  getElementsByClassName（sample）
  

它可用于任何元素，包括 document （如 document.getElementsByClassName ）。问题是，旧的浏览器不支持这一点。相反，您可以使用jQuery来做同样的事情：

  $（。sample）
  

希望这有助于您！

Hi How can I get hold of elements within a Div that uses a class say "sample"?

There are many Div's in the document

<div class="sample"/>
..
<div class="sample"/>
..
<div class="sample"/>
..
<div id = "samplediv">
  <div class="sample">
  <div>
</div>

My question was to find the div with class sample and manipulate some properties of this div. So I want to get hold of the Div with class = "sample"?

解决方案

In most modern browsers, you can get objects by class name using the function:

getElementsByClassName("sample")

This is available on any element, including document (as in document.getElementsByClassName). Problem is, older browsers don't support this. Instead, you can use jQuery to do the same thing:

$(".sample")

Hope this helps!
