[mapserver-users] ways to get map scale value

[Hankley, Chip]

Do you mean beyond the use of [SCALE]?

See the template reference in the docs.

http://mapserver.gis.umn.edu/doc36/template-reference.htmlhttp://mapserver.g
is.umn.edu/doc36/template-reference.html

Note the need for *some* caution using this, as the docs say 

"Current image scale. The exact value is not appropriate for user
information but essential for some applications. The value can be rounded
e.g. using JavaScript or server side post processing.:

Here's an example using JavaScript to make it more 'palatable' in the
display:

<script language="javascript">
function fnxRoundNo(i) {
  var new_scale;
  new_scale = separate(Math.round(i/100)*100, ",");
  
  document.write("Scale 1:" + new_scale);
}
function separate(input, separator) {
    input = "" + input;
    var output = "";
    for (var i=0; i < input.length; i++) {
      if (i != 0 && (input.length - i) % 3 == 0) output += separator;
      output += input.charAt(i);
    }
    return output;
}
</script>

... here's the pertinent HTML

<script>fnxRoundNo([scale]);</script>

Does anyone know any easy way (without using mapscript) to get the map scale
value?  Or, do I need to use mapscript to get the map scale? 
Thanks in advance!
