Removing a function in jQuery

Question

I need to be able to remove a function on a click event.

I have looked at the unbind and nullifying but I am unsure of the best solution, is there a destroy ability - I can't seem to find one. I need to be able to run the function again when I click .button

$('.button').on('click', function (e) {
    run();

    $('.back').on('click', '.back', function () {
        //remove the run function
    });
});

function run() {
    //code
}

I have also tried nullifying the function but it doesn't remove the event fully,

run = null;

run = function () {};

Thank you

You can use jQuery.unbind('click') to remove a previously-attached event handler from the elements.

what happens if he has other logic in that event beside the run function?

You can use jQuery.noop():

run = $.noop();

Try:

var isRun = 0;
$('.button').on('click', function (e) {
   if(isRun == 0) {
    run();
} 
});
  $('body').on('click', '.back', function () {
       isRun = 1;
    });
function run() {
    //code
}

$('.back').on('click', '.back', function () {
        function run() {}//empty function will override original function on click
    });

The previous answer may work. If not, try this: run().remove
