Jquery Script Blocking Keyboard Input in Form Fill

Even after revising the code the first time around I then came to realize it wasn't just blocking the form fills but everything else unassigned. After initially fixing it temporarily I then found not only were keypresses being blocked but so were unassigned buttons and anchors. I needed a way to turn that bit of code on and off. This is where I came across a solution provided by BenG from 2015 here: JQuery: Disable click event.

With his code and a few modifications to the existing code, the below code resolved the problems with both unassigned clicks and keyboard entries being denied.

Changed this:

         //any unassigned clicks / buttons would not work with this code.
         $('#ts_container').on('click', 'button, a', handleEvent);

         // any unassigned keypress events would not work with this code.
         $(document).on('keypress', handleEvent);  

To This:

jQuery(document).ready(function($) {

    $.fn.disableClick = function (disable){
        this.each(function() {
            if(disable){
                if(this.onclick)
                $(this).data('onclick', this.onclick).removeAttr('onclick');
                if($._data(this, 'events') && $._data(this, 'events').click)
                $(this).data('click', $.extend(true, {}, $._data(this, 'events').click)).off('click');
            }
            else{
                if($(this).data('onclick'))
                this.onclick = $(this).data('onclick');
                if($(this).data('click'))
                for(var i in $(this).data('click'))
                $(this).on('click', $(this).data('click')[i].handler);
            }
        });
        return this;
    };

    function handleEvent(e){
        var id = null;          
        var fade_out;
        var fade_in;
    
        if (e.type === 'click'){
            id = $(this).attr("id");
        }else{
            id = e.which;
        }
        
        switch (id){
            case 13:
            if ($('#click_1').is(':visible')){
                fade_out = '#start_1';
                fade_in  = '#step_0';
            }
            break;              
            ..etc..
            default:
            break;
        }   

        if($('#service_form').is(':visible')){
            $('#ts_container').disableClick(false);
            document.removeEventListener('keydown', handleEvent);
        }           
        e.preventDefault();         
    }
    
    $('#ts_container').on('click', 'button, a', handleEvent);
    document.addEventListener('keydown', handleEvent);
        
    function resetListeners(){
        $('#ts_container').disableClick(true);
        document.addEventListener('keydown', handleEvent);
    }
    
    $('#wpforms-submit-531').on('click', resetListeners);
});
