Get Element’s Value – Name – ID – ATTR – CLASS

Handy script, whenever you click an element with a class called .button it will alert the name and value of that element.

Or try this

var emailaddress = $('.changeme').text();

You could even swap the button text when you click by using this method.

Last resort!

var clickedon = $(this).children('.tablebutton').attr('value');
alert (clickedon);
