jQuery / Get numbers from a string

Question

I have a button on my page with a class of comment_like and an ID like comment_like_123456 but the numbers at the end are variable; could be 1 to 1

Answer 1

In your click handler:

var number = $(this).attr('id').split('_').pop();

Answer 2

This is a task for plain-old regular expressions, it has nothing to do with jQuery:

"comment_like_123456".match(/\d+/)

=> ["123456"]
