从标题创建Slugs？ [英] Creating Slugs from Titles?

问题描述

我已经掌握了从头衔创造slu g的一切，但有一个问题。我的RegEx用连字符替换空格。但是当用户输入Hi   （多个空格）时，slug最终会变成Hi ----- there。什么时候真的应该是Hi-there。

I have everything in place to create slugs from titles, but there is one issue. My RegEx replaces spaces with hyphens. But when a user types "Hi     there" (multiple spaces) the slug ends up as "Hi-----there". When really it should be "Hi-there".

我应该创建正则表达式，以便它只在任何一边有字符时替换空格吗？

Should I create the regular expression so that it only replaces a space when there is a character either side?

或者有更简单的方法吗？

Or is there an easier way to do this?

推荐答案

我用这个：

yourslug.replace(/\W+/g, '-')

用一个破折号替换所有出现的一个或多个非字母数字字符。

This replaces all occurrences of one or more non-alphanumeric characters with a single dash.
