如何获得位于2个引号之间的子字符串? [英] How can I get a substring located between 2 quotes?

问题描述

我有一个看起来像这样的字符串:您需要的单词是'hello'".

I have a string that looks like this: "the word you need is 'hello' ".

将"hello"(但不带引号)放入javascript变量的最佳方法是什么?我想办法是使用正则表达式(我对此了解甚少)?

What's the best way to put 'hello' (but without the quotes) into a javascript variable? I imagine that the way to do this is with regex (which I know very little about) ?

任何帮助表示赞赏！

推荐答案

使用 match() :

> var s =  "the word you need is 'hello' ";
> s.match(/'([^']+)'/)[1];
"hello"

这将匹配开始的'，然后是除'之外的所有内容，然后是结束的'，将所有内容存储在 first 捕获组中.

This will match a starting ', followed by anything except ', and then the closing ', storing everything in between in the first captured group.
