我想替换每6个div类。

这是我当前的代码

<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div> this should be change
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div> this should be change
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div> this should be change
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div>

它是不受限制和未定义的计数，因为它在的每个部分都有变化

你可以试试这个：

$( "div:nth-child(6n)" ).removeClass("disp");

或

$( "div.disp:nth-child(6n)" ).removeClass("disp");

<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div> 
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div> 
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div>
<div class="disp">...</div>

使用纯css 进行此操作

div {
    width:50px;
    height:50px;
    background:black;
    margin:10px;
}
section > div:nth-child(6n) {
    background:red;
}

这里也可以用jquery 来实现

 $( "div:nth-child(6n)" ).removeClass("disp");
