Question regarding how to dynamically change external javascript source information

[vfpuglia]

Hi,

Lets get it out there... I'm a newbie to javascript.

I'm trying to build a string for the external source file destination
and be able to change the keywords in the string based on what the
user presses/inputs. So here is what I have so far

<script>

.... some javascript to get the keyword arguments out of the URL ...

//build the src destination w/ the keywords
var $myURL;
$myURL = "http://www.foo.com/?keyword=";
$myURL += qsParm['keyword'];

</script>

..
..
some HTML for the page
..
..

<script src=" XXX "></script>

How do I get the XXX to be my variable that I built up at the top of
my page? I feel like I've tried everything... If I printout the
variable to the page - it is correct so its there, just dont know how
to pass it to src.

Please help

Thanks!
Vince

<script src=" XXX "></script>

How do I get the XXX to be my variable that I built up at the top of
my page? I feel like I've tried everything... If I printout the
variable to the page - it is correct so its there, just dont know how
to pass it to src.

<script>
var headID = document.getElementsByTagName("head")[0];
var newScript = document.createElement('script');
newScript.type = 'text/javascript';
newScript.src = XXX;
headID.appendChild(newScript);
</script>

The moment headID.appendChild is executed the source file you specified
( XXX ) will attempt to be loaded, the javascript file compiled and then
executed.

That's pretty much all there is to it. If you'd like to see a few nifty
things that can be done with this you can check out an article I wrote
on the subject (warning self promoting link incomming)

Good luck!

document.write('<script src="' + XXX + '"><\/script>')
