Good day. Your video is getting the closest to an answer I think I might need. So what f Im not on a child theme but a custom theme entirely?

What if we want to use plain javascript?

[@plethorathemes]

Hello Edward. You can use plain JavaScript without any problem. Just replace the jQuery code with a simple JS function.

@@plethorathemes Thanks. Would you be able to share the code for plain Javascript?

[@plethorathemes]

@@edwards9845 Sure. You can use the following code:
document.addEventListener("DOMContentLoaded", function(){
alert( php_data.message );
});
Let us know if everything worked out OK for you.
