Does anyone know where you would initialize a javascript function in zen cart for an index.php?main_page=index&cPath=1. Can I make this a separate js file and link it in the head by placing a jscript_initializeFunction.js in the includes/modules/pages/index directory of my zen cart? or is there better practice out there for zen cart to initialize the function in say html_header.php or something of that sort?
