问题描述

我有一个 div 的列表,我想使用nth-child选择器来设置样式。我还希望能够排除 div ,如果它有一个特定类,例如:

 < style> 
.a:not(.b):nth-​​child(2n){
color:hotpink;
}
< / style>

< div class =a>测试< / div>
< div class =a b>测试< / div>
< div class =a>我应该是粉红色的,因为我是第二个孩子,没有一个b类< / div>
< div class =a>测试< / div>
< div class =a>测试< / div>
< div class =a>测试< / div>
< div class =a>测试< / div>
< div class =a>测试< / div>
< div class =a>测试< / div>

解决方案

我认为最好的方法是使用jQuery和两个filter()调用:

  $('。a')。filter return $(this).hasClass('b'); 
})filter(
function(i){
return(i + 1)%2 == 0;
}
).css('color','hotpink');

:not和:nth-​​child没有我们想要的那么灵活>

I have a list of divs that I want to style using the nth-child selector. I also want to be able to exclude a div if it has a certain class, i.e:

<style>
 .a:not(.b):nth-child(2n) {
    color: hotpink;
 }
</style>

<div class="a"> Test </div>
<div class="a b"> Test </div>
<div class="a"> I should be pink, as i am the 2nd child that doesnt have a "b" class </div>
<div class="a"> Test </div>
<div class="a"> Test </div>
<div class="a"> Test </div>
<div class="a"> Test </div>
<div class="a"> Test </div>
<div class="a"> Test </div>

解决方案

I think the best way would be to use jQuery and two filter() calls like:

$('.a').filter(function(){
        return !$(this).hasClass('b');
     }).filter(
    function(i){
        return (i+1)%2 == 0; 
    }
).css('color','hotpink');

:not and :nth-child are not as flexible as we would like (unfortunately)
