Extract a number from a string (JavaScript)

Question

I have a string in JavaScript like #box2 and I just want the 2 from it.

I tried:

var thestring = $(this).attr(\'href\');
var          


        

Answer 1

You can use regular expression.

var txt="some text 2";
var numb = txt.match(/\d/g);
alert (numb);

That will alert 2.
