HTML being stripped of Javascript

Here’s a one-time self destructing link you can use to see it working on my test site – https://privnote.com/Btlxrzs4#1COcUMN8e

There is always a way my friend.

The best way would be to find what is causing this, most likely another plugin or a theme setting of which you’d have to disable and test. If the site is already in production this may not be an option and I’d then suggest making a duplicate you can test with offline or via sub-domain.

One method might be to use a shortcode to inject your custom code into the page by pasting a unique shortcode into an elementor widget such as the shortcode or text editor widgets.

You would need to be using a theme you can modify, child theme’s are best if your theme is public and gets updates. There is much documentation around the web on how to set up a child theme if you are not already using one.

In your child theme’s functions.php you can add something like this:

//add Eventbrite checkout widget
function sb_eventbrite_checkout_shortcode() {
    ob_start(); //this captures the html below

    ?>
<div id="eventbrite-widget-container-75687396039"></div>

<script src="https://www.eventbrite.com/static/widgets/eb_widgets.js"></script>

<script type="text/javascript">
    var exampleCallback = function() {
        console.log('Order complete!');
    };

    window.EBWidgets.createWidget({
        // Required
        widgetType: 'checkout',
        eventId: '75687396039',
        iframeContainerId: 'eventbrite-widget-container-75687396039',

        // Optional
        iframeContainerHeight: 425,  // Widget height in pixels. Defaults to a minimum of 425px if not provided
        onOrderComplete: exampleCallback  // Method called when an order has successfully completed
    });
</script>
    <?php

    return ob_get_clean(); //this spits it out
}
add_shortcode('eb_checkout', 'sb_eventbrite_checkout_shortcode');

And then simply add the following [eb_checkout] shortcode to your Elementor page content where you desire it’s output.

WordPress has so many hooks and filters even this could be filtered by an outside mechanism from any active plugin or theme so your best best is trying to figure out what is causing this behavior otherwise it will haunt you.

Best of luck and success to you!
