jquery getElementsByClassName查找部分类名

问题描述

我想使用javascript函数getElementsByClassName来循环一些没有确切类名的html div，但它以相同的文本开头：akordeon-item

I want to use the javascript function getElementsByClassName to loop in some html divs that don't have the exactly class name, but it starts with the same text: "akordeon-item"

因此，html文本如下所示：

So, the html text looks like this:

<div class="akordeon-item akordeon-item-first">

<div>
    <span class="userid">
          [email protected]
    </span>
</div>
</div>
<div class="akordeon-item akordeon-item-second">

<div>
    <span class="userid">
          [email protected]
    </span>
</div>
</div>
<div class="akordeon-item akordeon-item-third">

<div>
    <span class="userid">
          [email protected]
    </span>
 </div>
 </div>

 <div class="akordeon-item akordeon-item-fourth">

<div>
    <span class="userid">
          [email protected]
    </span>
</div>

另外，我试过的javascript代码就是这个：

Also, the javascript code I tried is this one:

var slides = getElementsByClassName(".akordeon-item");
for(var i = 0; i < slides.length; i++)
{
   alert("element : "+slides[i]);
}

我也尝试在getElementsByClassName方法中搜索此字符串：akordeon-item

I also tried searching for this string inside the getElementsByClassName method : "akordeon-item"

如何使这个循环工作？
请帮忙...

How can I make this loop work?Please help...

推荐答案

：

^= is starts with

$= is ends with    
=  is exactly equal
!= is not equal
*= is contains

尝试：

$.each($('[class^="akordeon-item"]'), function(key, value) {
    console.log(key, value);
});

迭代集合的替代方法：

$('[class^="akordeon-item"]').each(function(key, value) {
    console.log(key, value);
});

或使用代表循环：

var slides = $('[class^="akordeon-item"]');
for (var i = 0; i < slides.length; i++) {
    console.log(slides[i]);
}
