Question

I would like to avoid JavaScript in my HTML/PHP-Templates. Everything is working fine as long as I don’t need a base/root-URL in my external, included JS-File.

Problem:
Does anybody know a solution to put the JS logic (code below) into an external JS file? The main problem: how to figure out the _BASE_URL_? Unfortunately its not a form where you can get the URL by the action-attribute. I dont want to compile JS/PHP-mixed files, it has to be pure JS.

Idea (too dirty): A hidden input in the top of the body-tag with id=”root_url” or a variable in the main JS file: root_url = “http://localhost/projects/project/version/”. This is prone to failure, because no file could work stand-alone.

Maybe there’s a good htaccess/mod_rewrite solution?

Notice: I dont want to get the hostname or the “real” root dir, because it has to work in subfolders as well!

Code:

<script type="text/javascript">
// document ready
$(function() {
    // function: load items
    function load_items() {
        $("#items").load("<?php echo _BASE_URL_?>/items.php");
    }

    // load items!
    load_items();
});
</script>

<!-- target div --> 
<div id="items">loading</div>

Thanks in advance!

Can i see your html structure

function getBaseURL () {
   return location.protocol + "//" + location.hostname + (location.port && ":" + location.port) + "/";
}

if you need a path also use this

path = window.location.pathname.split( '/' );
console.log(path);
