passing php variables to external .js files

[eluser]CroNiX[/eluser]
What I do is in the head of my document, which is part of a view file that gets parsed by CI, I define the variables.

Code:

<skript type="text/javascript">
  var base_url = "&lt;?php echo base_url(); ?&gt;";
  //etc
</skript>

Then my external js apps can use base_url because it is already defined in js in the head of the document, before any other scripts are loaded.
