jQuery / Get numbers from a string

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 1000000.

When this button is clicked, I need to grab the end number so I can run tasks on other elements with the same suffix.

Is there an easy way of grabbing this number in jQuery?

$('.comment_like').click(function() {
    var element_id = $(this).attr('id');

    // grab number from element ID

    // do stuff with that number

});

You can get it like this:

var suffix = 'comment_like_123456'.match(/\d+/); // 123456

With respect to button:

$('.comment_like').click(function(){
  var suffix = this.id.match(/\d+/); // 123456
});

In your click handler:

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