Steve,
We use frames for our mapserver apps (www.geo.ou.edu <http://www.geo.ou.edu>
click interactive mapper). There needs to be a form (say MAPSERV form) in a
frame that is not the map frame that targets the map frame. When the map
frame loads, it needs to push relevant values to the MAPSERV form:
parent.framename.MAPSERV.imgext.value = "[mapext]";
parent.framename.MAPSERV.centerx.value = "[center_x]";
parent.framename.MAPSERV.centery.value = "[center_y]";
You may need to push something else, but these are the basics. We chose to
put our MAPSERV form in the frame that held the legend / active layer /
layer visible controls because that was the majority of the form. In other
words, it was easier to write imgext, centerx, and centery to the MAPSERV
form then to write each layer's status.
Here's a general outline of our setup:
toolFrame:
zoom in, zoom out, zoom full, pan, identify, etc...
each tool fires javascript that sets some status in the MAPSERV form (mode,
zoomsize, etc...) in preparation for that tool's map click or drag.
legendFrame:
holds MAPSERV form containing everything from layerstatus to mapsize.
this form is submitted anytime anything happens involving mapserver, but it
NEVER is targeted to itself so it can maintain state.
mapFrame:
targeted from MAPSERV form for map status changes (extent, layers, mapsize,
etc..)
onload pushes values from the map to legendFrame, toolFrame , whatever
necessary.
idFrame:
targeted from MAPSERV form for itemquery / identify results or any results
that are not a map and are small enough not to need their own window.
I'd love to be able to tell you that it was easy to get all these frames
talking with each other, but if you persevere I think it (the interface that
results) is worth it.
And my 2 cents on javascript is: if you can write more than one line per
hour per supported browser, you are doing well...
Good luck!

Hi All,
I've tried (with no luck) to implement a simple mapserver app. using frames,
but since I am a novice in Javascript, I need your help.
I have a launching app called demo_init.html that contains -
<form method=GET name = "mapserv" action="/cgi-bin/mapserv.exe">
<input type="hidden" name="map" value="C:\Inetpub\wwwroot\demo.map">
<input type="hidden" name="layer" value="roads">
<input type="hidden" name="zoomsize" value=2>
<input type="hidden" name="program" value="/cgi-bin/mapserv.exe">
<input type="hidden" name="map_web_imagepath"
value="C:\inetpub\wwwroot\tmp\">
<input type="hidden" name="map_web_imageurl" value="/tmp/">
<center><input type="submit" value="Initialize"></center>
And I have the file Demo.html -
<form method=GET action="[program]">
<INPUT NAME="img" TYPE="image" SRC="[img]" width=600 height=600 border=0>
and a few other mapserver lines like -
<option value="roads" [roads_select]> Roads
<INPUT NAME="ref" TYPE="image" SRC="[ref]" border="0">
etc.
In my map file, I have -
TEMPLATE Demo.html
=====================================
Now, I created a Main.html that has two frames (Left and Right)
<FRAMESET cols="230,*">
<FRAME src="http://localhost/LeftFrame.html
<http://localhost/LeftFrame.html> " name="Left" >
<FRAME src="http://localhost/Demo.html <http://localhost/Demo.html> "
name="Demo">
</FRAMESET>
And changed the map file to -
TEMPLATE Main.html
==================================
But this does not work. any help would be welcomed!
Thanks
