jQuery:包含选择器来搜索多个字符串 [英] jQuery :contains selector to search for multiple strings

问题描述

假设我有:

<li id="1">Mary</li>
<li id="2">John, Mary, Dave</li>
<li id="3">John, Dave, Mary</li>
<li id="4">John</li>

如果我需要找到所有的<li>包含John"和Mary"的元素，我将如何构造jQuery?

If i need to find all <li> Elements which contain "John" and "Mary", how would i construct the jQuery?

搜索单个字符串似乎很容易:

A search for a single string seems easy:

$('li:contains("John")').text()

我正在寻找类似下面的伪代码:

I am looking for something like the following pseudo code:

$('li:contains("John")' && 'li:contains("Mary")').text()

谢谢！

推荐答案

答案

要查找 li 的文本包含 BOTH Mary AND John:

Answer

To find li's that have text containing BOTH Mary AND John:

$('li:contains("Mary"):contains("John")')

要查找具有包含 Mary OR John 的文本的 li:

To find li's that have text containing EITHER Mary OR John:

$('li:contains("Mary"), li:contains("John")')

说明

把 :contains 想象成一个类声明，比如 .class:

Explanation

Just think of the :contains as if it was a class declaration, like .class:

$('li.one.two').      // Find <li>'s with classes of BOTH one AND two
$('li.one, li.two').  // Find <li>'s with a class of EITHER one OR two

:contains也是一样的:

$('li:contains("Mary"):contains("John")').      // Both Mary AND John
$('li:contains("Mary"), li:contains("John")').  // Either Mary OR John
