can I use a function to call an external javascript file?

[php_joe]

Hi,

 

I know how to use an external javascript file:

 

<script 
language="javascript" src="external_file.js"></script>

 

The thing is that some of the variables will be constantly changing (via php).

 

JavaScript doesn't seem to have anything equivilant to PHP's file() or file_get_contents() functions for local files, right? So I thought I could put the php on an external javascript code and have it loaded via a function.

 

Is there a way to load a script from an external file (located locally) each time a function is used?

 

Thanks,

 

Joe
