The Google Maps feature is not appearing on the webpage as expected

I'm currently working on a website that features a footer with a Google Map. The homepage displays this footer without any issues:

However, in other pages, I've implemented the footer by calling it from an external file using jQuery as shown below:

<script> 
    $(function(){
        $('#header').load('header_contact.html')
        $('#fatFooter').load('footer.html')
        $('#rightNav').load('rightNav.html')
    });
</script>

Unfortunately, when the footer is loaded like this, the map doesn't always display - it's hit or miss.

Could there be a simple solution to ensure the map appears correctly every time a page loads? Ideally, I'd prefer not having to manually code the footer onto every single page.

If you have any suggestions, please feel free to share them. Thank you!

When you trigger the function initializeMap(), the element #map_canvas may not yet exist (it will be loaded later).

Execute the function within the load callback event:

$('#fatFooter').load('footer.html',function(){if(!window.map){initializeMap();}});

Also, make sure to include this at the beginning of the initializeMap() function to prevent errors:

if(!document.getElementById('map_canvas')){return;}

Typically, the issue at hand is related to conflicts within the CSS file or difficulties in locating a specific element, resulting in the browser resorting to default values. Upon inspection of the console log for your homepage, no errors were detected. However, upon further examination of other pages, an error was identified: "Uncaught TypeError: Cannot Read property 'offsetWidth' of null," specifically pertaining to the maps width value. This issue may be attributed to the 404 errors present on all pages besides index.html, as indicated in the Source tab of your browser. To address this concern, resolving these 404 errors should effectively resolve the problem you are experiencing.

There is a potential race condition occurring between the loading of header, fatFooter, and rightNav files and your callMap script. Since these files are loaded asynchronously, there is no way to predict which will finish first. To avoid the callMap script running before fatFooter is fully loaded, consider using a callback function instead of relying on the window's load event.

To address this issue, one approach could be to encapsulate the body of init_map in a try/catch block (to handle any unexpected timing conflicts) and include a script at the end of footer.html that triggers init_map - also enclosed within a try/catch block. This way, at least one try/catch block will execute regardless of the loading sequence.

Alternatively, you can establish a custom event triggered upon the completion of footer.html loading, which can then be detected by the callMap script for synchronization purposes.
