使用jQuery检查是否所有的div都被隐藏 [英] Use jQuery to check if all div's are hidden

问题描述

我如何检查是否所有的div与类测试是隐藏的。如果他们都隐藏，设置wrap1为隐藏。感谢。

How would I check if all the div's with class test are hidden. And if they are all hidden set wrap1 to hidden. Thanks.

<div id='wrap1'>
<div class="header">Header 1</div>
<div class='test'><a href="#">Test 1</a></div>
<div class='test'><a href="#">Test 2</a></div>
<div class='test'><a href="#">Test 3</a></div>
</div>

推荐答案

您可以使用上面建议的选择器进行检查，如下所示： / p>

You can do the check as by using selector as suggested above and to it like this:

 if ( $("div.test:visible").length === 0)
      $("#wrap1").hide( );
