div的条纹类 [英] Stripe class for div

问题描述

我有一长串多个div ...比方说20 div

I have a long list of multiple div... let's say 20 div

全部包裹在另一个包裹中.

All wrap in another one..

<div id="main">
 <div class="xyz"> text text </div>
 <div class="xyz"> text text </div>
 <div class="xyz"> text text </div>
 <div class="xyz"> text text </div>
 <div class="xyz"> text text </div>
.... etc
</div>

我喜欢在每两个div中添加一个灰色"类，并将其设置为斑马！ 请使用jquery！

i like to add class "grey" in one out of two div and make it zebra ! jquery please !

推荐答案

$('.xyz:odd').addClass('grey');

请注意，灰色"不是语义类名.最好将id称为"odd"或"zebra"或其他名称.如果您下定决心，将奇数颜色更改为蓝色，则您的类名将是真的很奇怪:P

Do mind that 'grey' is not a semantic classname. Better call id 'odd' or 'zebra' or something. If you'd make up your mind and change the odd color to blue your classname would be real strange :P
