需要一个正则表达式来在javascript中拆分字符串

Question

I need some help with regular expressions in javascript. I've got a string like:

var S = '["abc","defg", "hij"]';

How could I split it in javascript to get a[0]=abc , a[1]=defg , a[2]=hij ? Because var a = S.split(','); just give me a[0]=["abc" and so on. Thank you very much.

Answer 1

If you fix the quotes you use to delimit the string, then you can JSON.parse the string to an array and work with it as you need, like this:

 var s = '["abc","defg", "hij"]'; var arr = JSON.parse(s); console.log(arr); console.log(arr[0]); // = 'abc' 

Answer 2

If you mean:

var S = ["abc", "def", "ghi"];

Then use S[0], S[1] and S[2].

If you mean:

var S = "[\"abc\", \"def\", \"ghi\"]";

Then use JSON parser

Complete example:

var S = "[\"abc\", \"def\", \"ghi\"]";
var SParsed = JSON.parse(S);
alert(SParsed [1]); //def
