如果链接包含特定文本，jQuery将类添加到href [英] jQuery add class to href if link contains specific text

问题描述

我的网站列表中有一些链接到文件的动态填充链接。是否可以使用jQuery查看文件的名称是否以.pdf结尾，如果链接文本以.mp3结尾，则将类添加到href或类似内容？

I have some dynamically populated links in a list on my site that link to files. Is it possible to use jQuery to see if the name of the file ends with .pdf and add a class to the href or similar if the link text ends with .mp3?

例如，我的列表中有以下链接：

For example I have the following links in my list:

• Document1.pdf


• Song1。 mp3


• Song2.m4a


• Document2.doc

• Document1.pdf
• Song1.mp3
• Song2.m4a
• Document2.doc

我想检测结束字母并在链接中添加不同的类，因此对于包含文本Document1.pdf的链接，我将类 pdf 添加到锚元素，以及文本Song1.mp3的链接我将类 mp3 添加到锚元素。

I would like to detect the end letters and add different classes to the links, so to the link which has the text Document1.pdf I'd add the class pdf to the anchor element, and the link with the text Song1.mp3 I'd add the class mp3 to the anchor element.

使用属性选择器：
