[mapserver-users] mapserver+javascript without template example?!!!

Sun Sep 9 22:46:25 PDT 2012

Thanks for your help
I changed my file to follows:
</head>
    <script language="JavaScript">
        function zoom(){
            document.forms['mapserv'].submit();
        }
    </script>
<body>
<h1> A Dynamic Map </h1>
<p></p>
<h3> use form to make map dynamic + scripting </h3>
    <form name="mapserv" method="get" action="/cgi-bin/mapserv.exe">
        <input type="hidden" name="imgxy" value="[center]">
        <input type="hidden" name="map" value="[map]" />
        <input type="hidden" name="imgext" value="[mapext]" />
        <input type="hidden" name="layers" value="[layers]" />    
        <input type="hidden" name="mode" value="map" />

        <input type="hidden" name="zoomsize" value="2" />

        <input type="image" name="img" src="http://localhost/cgi-bin/mapserv.exe?map=/ms4w/apps/ms101/htdocs/ms101.map&layers=all&mode=map"  onclick="zoom()"/>

    </form>

</body>
<html>

If i click on image, i get a response from mapserver correctly. In fact, in loading the above page, mapserver properly fills variables like [map]. This is the url after clicking map:
http://localhost/cgi-bin/mapserv.exe?imgxy=400+200&map=%2Fms4w%2Fapps%2Fms101%2Fhtdocs%2Fms101.map&imgext=-180+-90+180+90&layers=[layers]&mode=map&zoomsize=2&img.x=228&img.y=108

But when i remove <input type="hidden" name="imgxy" value="[center]">, mapserver does not substitutes any variable.

this is the url after clicking map:
http://localhost/cgi-bin/mapserv.exe?map=[map]&imgext=[mapext]&layers=[layers]&mode=map&zoomsize=2&img.x=618&img.y=160

Why MapServer behaves like this? (useful for mentioning, there is no template defined in map file)

You should verify what exact request is sent to the server... I would 
assume something like "map=[map]" is sent. Use Firebug of any other 
debugging tool.
