javascript - How do I split words in a String with JavaScript regex?

Question

I have the String "Edit[user]", but I need get "Edit" and later "user".

How can I do it? Any help would be useful.

Of course I need do it with JavaScript regex.

Answer 1

var regex = /(.+)\[(.+)\]/;
var str = "Edit[user]";
regex.exec(str); // will return ["Edit[user]", "Edit", "user"]

或者您可以使用以下String#split方法这样做：

var str = "Edit[user]";
str.split(/\[(.+)\]/); // will return ["Edit", "user"]

Answer 2

您正在寻找的是分组。我将快速解释这些在 JavaScript 中是如何工作的，并将实际的正则表达式留给你。

var myString = "cat dog frog";
var myRegexp = /(cat).*(frog)/g;
var match = myRegexp.exec(myString);

match 将是一个数组，索引 0 将具有整个匹配项，任何其他将具有组的内容。

match[0] = "cat dog frog"
match[1] = "cat"
match[2] = "frog"
