AW: [mapserver-users] Micro-HowTo Display SCALE

Mon Dec 17 01:38:05 PST 2001

Hi Steves,
it is easy to cut off the scale decimals with some javascripting in the
template file, eg.:

<html>
<head>
   <title>MapServer HTML Template</title>
<script language="JavaScript">
<!--
var my_scale=Math.round([scale]);
//-->
</script>
</head>
<body>
...
<script language="JavaScript">
<!--
document.writeln("<b>Scale ca. 1 : "+my_scale+"</b>");
//-->
</script>
...
</body>
</html>

Regards,
Andreas Maul

Steve,

I've posted this back to the list, maybe one of the developers can help
with this. I thought the number of decimal places was a bit excessive
myself :)

The only way to trim this up in html would be to write some javascript
:(

We seem to have a lot of Steves posting to this list!
