使用jQuery获取第一个和最后一个类
问题描述:
可能是一个新手问题。我有这样的代码行:
Might be a newbie question. I have a code line like this:
<div class="template active">
我需要自己获得每个课程。
I need to get each class for itself.
我试过这段代码:
$(this).attr("class");
从该代码我得到模板有效。我需要的是一个带有template的字符串和另一个带有active的字符串。
From that code I get "template active". What I need is one string with "template" and another with "active".
最好的jQuery函数是什么?示例?
What is the best jQuery function for that? Example?
答
var classes = $(this).attr("class").split(/\s/);
classes[0] === 'template'
classes[1] === 'active'
如果有两个以上的类名,你只想得到第一个&最后(这是你的问题)你可以打电话:
If there are more than two classnames and you only want to get the first & last (that was your question) you can call:
classes[0] = first class
classes[classes.length -1] = last class
