jquery extract number from string code example
Example 1: jquery extract number from string

var id_number = parseInt(id_of_div.replace(/[^0-9.]/g, ""));
console.log(id_number);

Example 3: get number from string using jquery
You can get it like this:
var suffix = 'comment_like_123456'.match(/\d+/);
With respect to button:
$('.comment_like').click(function(){
var suffix = this.id.match(/\d+/);
});
It works for me.
