jQuery Question

Intercept click event on a button, ask for confirmation, then proceed

Based on a variable

, I need to intercept a click event on a button, and ask for confirmation, if they say ok, proceed, otherwise ignore click.

So something like:

if(SomeCondition) {

// disable click on button

var isOk = window.confirm("Are you sure?");

if(isOk) {


Note: button1 has already been wired up with a click event via javascript from an external .js file that I can't change.

I don't know what the click event was bound too, so I have to disable the click if SomeCondition is true, then ask for confirmation, then continue with the click.

Process isOK your window.confirm within the function of the button

   if(window.confirm("Are you sure?"))
     alert('Your action here');

The issue you're going to have is the click has already happened when you trigger your "Are You Sure" Calling preventDefault doesn't stop the execution of the original click if it's the one that launched your original window.confirm.

Bit of a chicken/egg problem.

Edit: after reading your edited question:

    var myClick = null;

    //get a list of jQuery handlers bound to the click event
    var jQueryHandlers = $('#button1').data('events').click;

    //grab the first jquery function bound to this event
    $.each(jQueryHandlers,function(i,f) {
       myClick = f.handler; 
       return false; 

    //unbind the original

    //bind the modified one
        if(window.confirm("Are You Sure?")){
        } else {
            return false;
