jQuery不在特定的Wordpress页面上运行

Question

I've got a Wordpress page and i'm running some jQuery to show and hide 2 input fields when someone clicks a checkbox. The problem is that this code runs perfectly on my Homepage but when i try to do the same thing (using the exact same html structure & jquery) on a subpage, it no longer works. It's not that the file doesn't get loaded because 1 part of the jQuery file runs fine on that page and I even have a console.log at the end of the file to show the file is fully loaded.

www.yogagids.nl is the homepage, when you click the checkbox "Evenementen" 2 datepicker fields show up, deselect it and they are hidden. Thats how it should work.

www.yogagids.nl/listings Is the page where this doesn't work. Same story, click the "evenementen" checkbox and the 2 datepicker fields should show and hide. However on this page nothing happens.

I'm really at a loss here, any and all help would be greatly appreciated.

Here is all the code that runs on this page, the actual file is larger but i couldn't post that many characters.

    jQuery( document ).ready(function() {

        //Create dummy input fields (altField) to show the user, this way the user sees a proper dateFormat while saving Unix Timestamp in the database.
        //Do this for both the Add Listing page and the Search Fields 
        jQuery( "#event_date_start, #filter_event_date_start" ).after('<input type="text" class="input-text" name="event_date_start_dummy" id="event_date_start_dummy" placeholder="Begindatum"></input>');
        jQuery( "#event_date_end, #filter_event_date_end" ).after('<input type="text" class="input-text" name="event_date_end_dummy" id="event_date_end_dummy" placeholder="Einddatum"></input>');

        //Define Dutch format and naming for the calendars, set the calendar to use unix date (easier to compare), set an alternative field to show the proper format.

            dateFormat: "@",
            altFormat: "dd-mm-yy",

I'm almost certain that the checkboxes HTML elements don't exist or are missing the corresponding value/classes when you are binding the change event. Try using the on method and also capture the event in the parent element, taking advantage of "event propagation":

     jQuery(".listingTypeSelect").on('change', 'input[value=event]', function() {
        console.log('clicked');
        if (!jQuery(this).is(':checked')) {

            jQuery('.search_event_date').css('display', 'none');
            jQuery(".listingTypeSelect input[value=studio]").prop('disabled', false);
            jQuery(".listingTypeSelect input[value=teacher]").prop('disabled', false);

            if (jQuery(window).width() > 992) {
               jQuery('.search_home_row_2 > div').css('width', '33.333%');
            } else {
                jQuery('.search_home_row_2 > div').css('width', '100%');
            }


        } else {

            jQuery('.search_event_date').css('display', 'inline-block');
            jQuery(".listingTypeSelect input[value=studio]").attr('checked', false); // Unchecks it
            jQuery(".listingTypeSelect input[value=teacher]").attr('checked', false); // Unchecks it
            jQuery(".listingTypeSelect input[value=studio]").prop('disabled', true);
            jQuery(".listingTypeSelect input[value=teacher]").prop('disabled', true);

            if (jQuery(window).width() > 992) {
                jQuery('.search_home_row_2 > div').css('width', '23.333%');
                jQuery('.search_home_row_2 .search_event_date').css('width', '30%');
            } else {
                jQuery('.search_home_row_2 > div').css('width', '100%');
                jQuery('.search_home_row_2 .search_event_date').css('width', '100%');
            }

        }
    });

It might be necessary to capture the event higher in the DOM. Example in search_jobs div.

jQuery(".search_jobs").on('change', '.listingTypeSelect input[value=event]', function() {
   //Code
});

On https://www.yogagids.nl/ form is:

<form class="job_search_form" action="https://www.yogagids.nl/listings/" method="GET">

and on https://www.yogagids.nl/listings/ :

<form class="job_filters">

So it's about rendering different html and in second case you don't have action and method attributes.
