jquery change onclick event of href

Question

Hello All,

I have a href element and that has onclick event on it. I want to change the function after some event. I tried using jquery but the old one and new function both are fired. I want only the new one t be fired.

My Code is as:

<a href='#' id='cvtest' onclick='testMe("One")' >TEST</a>
 after some event i am adding following code:
$("#cvtest").click(function(){ testMe("Two"); });  

When i click "Test" link i get 2 alerts "One" and "Two".

How to stop the first event getting fired or is there any other solution to this problem?

Don't use the deprecated onclick property. Assign both event handlers using jQuery. Then it's easy to remove the one you no longer want.

// Add the original event handler:
var originalEventHandler = function() { 
    testMe('One');
};
$("#cvtest").click(originalEventHandler);

// Then later remove it and add a new one:
var newEventHandler = function() { 
    testMe('Two');
};
$("#cvtest").unbind('click', originalEventHandler).click(newEventHandler);
