Turn on/off the button click functionality on a jQuery smart wizard control

I am currently utilizing this particular control, which happens to be version 3 of jQuery Smart Wizard.

Here is the code snippet for the smart wizard:

$('#wizard').smartWizard({transitionEffect:'slide'});

These are some helper functions written in JavaScript:

function disableNextButton(){
    var $actionBar = $('.actionBar');
    $('.buttonNext', $actionBar).addClass('buttonDisabled').off("click");
}

function enableNextButton(){
    var $actionBar = $('.actionBar');
    $('.buttonNext', $actionBar).removeClass('buttonDisabled');
}

The CSS class actionBar is utilized to style the area where previous, next, and finish buttons are located. The style buttonNext is applied to the next button, while the style buttonDisabled gives a gray color to a disabled button. All these styles can be found within the Smart Wizard CSS files.

The issue I am facing is that while I can disable the button click event using the ".off" function of jQuery, I am unable to restore the original event handler with the ".on" method.

My question is: How can I restore the next button's click event after it has been disabled?

Thank you.

Answer №1

When using .off, the event handler is unlinked, requiring you to re-attach it. It's not as simple as just stating:

$('.buttonNext', $actionBar).removeClass('buttonDisabled').on("click");

Because jQuery doesn't retain information about the event that was previously bound or which specific event you intended to bind. To specify the function, you can utilize the click shorthand like so:

$('.buttonNext', $actionBar).removeClass('buttonDisabled').click(function() {
  // Your click code should be placed here.
});

Answer №2

Upon reviewing the jquery smartwizard code, I have devised a solution for the enableNextButton function as follows:

function activateNextBtn($wizard){
    var $navBar = $('.navBar');
    $('.btnNext', $navBar).removeClass('disabled')
            .bind('click', function() {
                $wizard.smartWizard('moveNext');
                return false;
            });
}

The jquery wizard instance is passed as an argument.

This approach effectively addresses the issue of re-enabling click functionality without duplicating code from the smart wizard plugin.
