Possible to call function in external .js from internal function?

@KhamulSep 05.2005

Is it possible to have a function in an external .js file, and then call this function from an internal script block? If it is, how do you do it? I have some validate-functions which can be used on several of my pages, and it would be more efficient to have them in external files, but I need to call those functions when I click the button.
I have tried searching, but the only results I get are how to make an external .js-file.

What if the js file is 3rd party and I have no means to modify it.

Effectively, I want to control when this script will be loaded (as it executes code immediately).

In some circumstances, I dont want the code to execute. So I need a way of dynamically 'including' the .js file.

Inside your html code you can do this,

<script type="text/javascript" scr="3rd_party_script.js"></script>

But, inside my html code, this script will always execute. How can I selectively do this from my own .js file?

Regards

Grant

use DOM methods to create it

ex:

in your page:

[code=php]
 <script type="text/javascript">
 function createEl(){
 var oJs = document.createElement('script');
 oJs.setAttribute('type','text/javascript');
 oJs.setAttribute('src','myjs.js');
 document.getElementsByTagName('head')[0].appendChild(oJs);
 call();
 }
 </script>
 [/code]

in myjs.js file, for instance:

[code=php]
 function call(){
 alert('blabla');
 }
 [/code]

Now when you fire the function createEl(), you will get the alert
