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

This would be the easiest way to grab number from a string using jquery.

$(function(){
	 $('.comment_like').click(function() {
    var element_id = $(this).attr('id');
    var number = element_id.match(/\d+/);
    
    alert(number);

  });
});
