Issues with HotelMap embeds

Issue Overview:

If you're experiencing issues with a HotelMap embed, such as content appearing at the bottom of your page or breaking the EE Builder, read on. This is a known recurring issue with the code outputted by HotelMap.com. While we have previously worked with their support to fix this for specific sites, they have yet to implement a universal fix for all sites.

Temporary Workaround:

To help you manage this issue temporarily, we have devised a workaround. This involves loading the script within an iframe.

Please follow the instructions below:

  1. Copy the below code into a text editor.
  2. Replace [Paste their embed code here] with the embed code provided by HotelMap.com.
  3. Copy and paste the updated code into your the HTML/Embed module you are using in Event Engine.
<iframe id="hotelmap_iframe" onload="resizeIframe(this)" style="width: 100%; border: none; overflow: hidden;"></iframe>
    
    <script>
        const iframeContent = `
            <!DOCTYPE html>
            <html lang="en">
            <head>
                <meta charset="UTF-8">
                <meta name="viewport" content="width=device-width, initial-scale=1.0">
                <title>Hotel Map</title>
                <style>
                    body {
                        margin: 0;
                        overflow-x: hidden;
                    }
                    #hotelmap_script {
                        width: 100%;
                    }
                </style>
            </head>
            <body>
            <!— ******************* —>
            <!— Their embed goes below —>
                
            [Paste their embed code here]

            <!— Their embed goes above —>
            <!— ******************* —>
            </body>
            </html>
        `;


        const iframe = document.getElementById('hotelmap_iframe');
        iframe.srcdoc = iframeContent;


        function resizeIframe(iframe) {
            iframe.style.height = iframe.contentWindow.document.body.scrollHeight + 'px';
        }


        iframe.onload = function() {
            const iframeDocument = iframe.contentDocument || iframe.contentWindow.document;
            const observer = new MutationObserver(() => {
                iframe.style.height = iframeDocument.body.scrollHeight + 'px';
            });
            observer.observe(iframeDocument.body, { childList: true, subtree: true });
        };
    </script>

Explanation:

This code forces the HotelMap script to load in an isolated iframe, preventing it from affecting the rest of your page.

Important Notes:
