Why must everything be in jQuery?

为什么一切都必须在 jQuery 中？

var lastword = yourString.split("-").pop();

This will split your string into the individual components (for exampe, Closed, Flat, Knit, Collar). Then it will pop off the last element of the array and return it. In all of the examples you gave, this is Collar.

这会将您的字符串拆分为单个组件（例如，Closed、Flat、Knit、Collar）。然后它将弹出数组的最后一个元素并返回它。在您提供的所有示例中，这是Collar.

I see there's already several .split().pop()answers and a substring()answer, so for completness, here's a Regular Expression approach :

我看到已经有几个.split().pop()答案和一个substring()答案，所以为了完整起见，这是一个正则表达式方法：

var lastWord = str.match(/\w+$/)[0];

Popworks well -- here's an alternative:

Pop效果很好——这里有一个替代方案：

var last = str.substring(str.lastIndexOf("-") + 1, str.length);

Or perhaps more simplified as per comments:

或者根据评论可能更简化：

var last = str.substring(str.lastIndexOf("-") + 1);

You don't need jQuery to do this. You can do with pure JavaScript:

您不需要 jQuery 来执行此操作。您可以使用纯 JavaScript：

var last = strLast.split("-").pop();
