jQuery Button.click() event is triggered twice

In that case, we can do the following

$('selected').unbind('click').bind('click', function (e) {
  do_something();
});

I had the event firing two times initially, when the page get refreshed it fires four times. It was after many fruitless hours before I figured out with a google search.

I must also say that the code initially was working until I started using the JQueryUI accordion widget.

Your current code works, you can try it here: http://jsfiddle.net/s4UyH/

You have something outside the example triggering another .click(), check for other handlers that are also triggering a click event on that element.

Strange behaviour which I was experienced also. So for me "return false" did the trick.

        $( '#selector' ).on( 'click', function() {
            //code
            return false;
        });

If you use

$( document ).ready({ })

or

$(function() { });

more than once, the click function will trigger as many times as it is used.
