jquery onclick click event

Question

I have div which has an onlcick event. Now when i click the div i want to change its onlick function with .click attribute of jquery. I am able to change it dynamically, but when i apply it the new event also gets fired. Is there any work around so that the new is not fired but just applied to the div with new function? Here is what i am trying to do

i have a div

<script type="text/javascript">

function testMe(data)
{
   alert(data);
   $('#testMe').unbind('click');
   $('#testMe').click(function(){ testMe('2');  });
}

</script>
    <div id='testMe' onclick='testMe(1)' >click on me, I will disappear.</div>

when I execute theabove code i still get value 1 om alert box THANKS EveryOne

Also i tried the below code but it is not working for me

 function testMe(data)
{
   alert(data);
   $('#testMe').unbind('click');
   $('#testMe').click( testMe(2) );
}

Though the code is updating the onlick event from 'testMe(1)' to 'testMe(2)' but it continuously alerts value 2. The work around this problem is traditional JS script code as:

 document.getElementById('testMe').onclick =  testMe(2) ;

And its working without alerts.

Could you show the code you're using? – kovshenin Oct 29 '10 at 14:44 — kovshenin, Oct 29 '10 at 14:44

use the 'one' function

$('element').one('click',function()
{
    alert('old click handler');
    $(this).click(function(){
        alert('new click handler, yarrrr');
    });
});

interesting way to remove the need to write the unbind line of code...i didn't know of this – Pete Amundson Oct 29 '10 at 14:55
one is intended to be fired only once (i dont get why they didnt call it once, but still ^_^) – DoXicK Oct 29 '10 at 15:00

maybe try this.

$('div').click(function(){
    $(this).unbind('click');
    $(this).click(function(){
        // new click function here
    });
});

what if there are other click handlers which he dont want to remove ? doing this using namespaces would be more functional - $('div').bind('click.once', function() { $(this).unbind('click.once').click(function() { }); }); - or use the 'one' function i gave. – DoXicK Oct 29 '10 at 15:02

Try using the bind event http://api.jquery.com/bind/

If you want to remove the previous event use the unbind event: Best way to remove an event handler in jQuery?

unbind old functionality first. Than bind the new event to it should do the trick.

Do you mean the the event is also fired when you bind it to the element?
