Javascript / Jquery – Get number from string

Using

var id = $(this).attr("class");

I get all the classes of the clicked link, var id returns 4 classes:

button_red 501 ajax-call class2

How do I extract the class ‘501’ and put it in an var like var id_numeric = 501 ?

Thanks for your advice

Answer 1

var numericClassIdMatches = $(this).attr('class').match(/\b\d+\b/);

In the above case, 501 would be numericClassIdMatches[0]
