Need a regular expression to split string in javascript

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.

Learn to use quotes properly, It would be better if you define your string as var s = '["abc","defg", "hij"]'; — Satpal

I don't see how the above code line works? there are unescaped quotes in the string... please edit. — Jean-François Fabre

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'

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
