preg_match in JavaScript?

Is it possible in JavaScript to do something like preg_match does in PHP ?

I would like to be able to get two numbers from string:

var text = 'price[5][68]';

into two separated variables:

var productId = 5;
var shopId    = 68;

Edit: I also use MooTools if it would help.

JavaScript has a RegExp object which does what you want. The String object has a match() function that will help you out.

var matches = text.match(/price\[(\d+)\]\[(\d+)\]/);
var productId = matches[1];
var shopId    = matches[2];

var text = 'price[5][68]';
var regex = /price\[(\d+)\]\[(\d+)\]/gi;
match = regex.exec(text);

match[1] and match[2] will contain the numbers you're looking for.
