Need help with Javascript

declaring variables and then calling javascript file

[wfernley]

Hey everyone,

I was curious how I can create a javascript that I declare variables in and then look to an external script to use these variables.

So basically... I declare the variables in the html file

<script">
var width = 330
var height = 306
</script>

And then call the javascript that uses the file which contains...

<script language="JavaScript">
document.write("Height=" + height + " Width=" + width);
</script>

Hopefully that made sense. :)

It's pretty simpe to declare variables in javascript and then use them in an external Javascript file.

What you need to do is firstly declare te variables like you have before.

<script>
var myWidth = 330
var myHeight = 306
</script>

And then include the external JS file as follows:

<script src="external-file.js"></script>

And then you can use the variables in the "external-file.js" like so:

alert("Height=" + myHeight + " Width=" + myWidth);

I hope this helps.
