mapsize

Thu Sep 2 16:58:44 EDT 2004

I use the javascript below. There might be a simpler/more elgant
solution, but it works.

Rich

<script language="JavaScript">
      var currMapSize = "[mapsize]";
	function MapSize (size)	{  // constructor
		this.size = size;
	}

	var mapSize = new Array();
		mapSize["Small"] = new MapSize("440 330");
		mapSize["Medium"]= new MapSize("645 485");
		mapSize["Large"] = new MapSize("900 675");

	// populate the map size option list
	function MapSize_place() {
		var s;

		for (name in mapSize) {
			s = "<OPTION value='" + mapSize[name].size + "'";
			s+= (mapSize[name].size == (currMapSize)) ? " selected" : "";
			s+=  ">" + name + "</OPTION>";
			document.write(s);
		}
	}

	MapSize.place = MapSize_place; // make above function a property of
the constructor
</script>

And then in the <BODY> the following:
       <SELECT name="map_size" onChange="reSize(this[selectedIndex].value);">
          <script language="JavaScript">
             MapSize.place();
          </script>
        </SELECT>
