jQuery / Javascript - How do I convert a pixel value (20px) to a number value (20)

Question

I know jQuery has a helper method for parsing unit strings into numbers. What is the jQuery method to do this?

var a = \"20px\";
var b = 20;
var c = $.parseM         


        

Answer 1

$.parseMethod = function (s)
{
    return Number(s.replace(/px$/, ''));
};

although how is this related to jQuery, I don't know
