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

More generally, parseFloat will process floating-point numbers correctly, whereas parseInt may silently lose significant digits:

parseFloat('20.954544px')
> 20.954544
parseInt('20.954544px')
> 20
