Function collected in external file - possible?

Hi - cool forum! This is my first post but *heck* here goes:

As far as I know a friend of mine put all his javascripts-functions in an external file and then refers to it from his "normal" html file.

How can I do that?
I've tried to ask him, but he has'nt answered me yet, so hopefully someone in here answers before him...

In advance - THX!

well, as a matter of fact it's very easy! You open a free document, whatever it is! Then you type your functions or variables that you like, then you save the file with the "js" extension ( Note : do not write your functions in the external file between <script> .... </script>, it's no need to do that for an external file).
Then you can call that file in any html file that you like by typing:

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

Notice that when you use a <script> tag for reading an external file, you shouldn't put any other statements between that tag and it's closing ( </script> ) tag.

It should also be noted that the file with the javascript in it should have no html in it. That means no <script> </script> tags, no <!-- --> comment tags or anything else. What it should contain is javascript, only javascript.

Thx for the quick responce!! :thumbsup:

I just have one question - maybe I'm a bit 'slow' but can't get it to work 100%

I've done all you've mentioned so far, but how do I call a specific function?

The way I did it is I've made different function with unique names etc, placed in that .js file. How do I then call e.g.
Function validateDiz();

from my html file? Is it
<script language="javascript" src="MyFile.js">
validateDiz();
</script>

or is it done in another way??

Once again - thx for fast responce!;)

That's the proper syntax I believe:

<script language="javascript" type="text/javascript" src="MyFile.js"></script>
<script language="javascript" type="text/javascript">
validateDiz();
</script>
