jquery onclick click event

Question

Hello All,

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.

Answer 1

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

If you want to remove the previous event use the unbind event: http://stackoverflow.com/questions/209029/best-way-to-remove-an-event-handler-in-jquery

Answer 2

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?

Answer 3

maybe try this.

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

Answer 4

use the 'one' function

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