Variables

rah222 · Jun 26, 2002

Hi there.

I was wondering if anyone could help me with the use of variables in scripting.

As an example, I have some images I have created which I am using in <a href ...></a>, but until I've finished designing things I won't know how many buttons there'll be or how big I'll want them. Therefore I want the ability to change the width and height values of the image in my HTML file without having to change them here, there and everywhere as I do know.

I've tried:

height_of_button = 31
width_of_button = 118

within <script language="javascript"></script>

but when I attempt

<img src ... height = height_of_button>

or

<img src ... height = &height_of_button>

the image doesn't even get rendered.

Can somebody please tell me how I use variables both:

(1) within the given HTML file
(2) globally amongst various HTML files linked together as a site

Thank you very much.

Russ.

vars.js content :

var height = 31;
var width = 118;

so then u can do :

<html>
<head>
<script language="javascript" type="text/javascript" src="vars.js"></script>
</head>
<body>
<script language="javascript" type="text/javascript">

</script>
</body>
</html> ---------------------------------------
