[Mapserver-users] Itasca Demo DHTML Help?

Jerod -

FWIW, it's always a good idea to reply to the list as well, that way
the entire thread gets archived for others to use.

Here's some code from a template file of USGS 7.5' Quadrangles.

<script language="JavaScript">
  var y = '[FILENA]';
  var z = y.substring(0,6);

  var w = window.open('','','resizable,status,width=625,height=400');
  var x = w.document;
  x.write("<!DOCTYPE HTML PUBLIC '-//W3C//DTD HTML 4.01
Transitional//EN' 'http://www.w3.org/TR/html4/loose.dtd'>");
  x.write("<html><head><title>[QUAD_NAME] Quadrangle</title>")
  x.write("</body></html>");
</script>

I'm not sure about your other issues. I imagine that you are referring
to what's going on in the main frame. That page doesn't use the CGI
placeholders, rather all of the MS functionality is tied to a JavaScript
object. So, for instance, in the DHTML app that Steve Lime wrote, you
would access SCALE by refering to it as ms.scale from JavaScript.
Therefore, you will probably have to modify the links that you were
using before to be built on-the-fly using JavaScript.

HTH!

I hate to do this, but since you have already worked it out, is there 
anyway you can send me snippets of the code to get the query results 
frame to fire a popup window with query results in it.
I have zeroed the query frame out and it uses blank.html as its src.

Also, since switching my interface to DHTML, all my URL strings that 
had cgi calls in them no longer work.

I had a URL string that would fire a page to show a printable copy of 
the map, but the variable placeholders (e.g.,[img]) in the URL no 
longer fill out from the cgi. Any ideas?

EX.
href="http://192.168.1.100/cgi-bin/mapserv?map_reference_status=on&mapsize=500

500&map=/Library/Apache2/htdocs/belize/demo.map&img=[img]&layer=[layers]&map_web_template=/Library/Apache2/htdocs/belize/print.html&mapext=[minx]+[miny]+[maxx]+[maxy]&map_web_imageurl=/tmp/"

And neither does the html variant way of building a legend. I used to 
be able to use the [legend] placeholder to place a template that 
would generate the legend in HTML on the fly, but it no longer works.

source:
[leg_layer_html order_metadata=WMS_ORDER visibility_flag=15]
     [if name=WMS_SHOWINLEGEND oper=isnull]

<tr><td class="smtext"><u>[metadata name=WMS_TITLE]</u></td></tr>[/if]
    [/leg_layer_html]

    [leg_class_html visibility_flag=15]
       <tr><td class="smtext">   <img src=[leg_icon] 
align="absmiddle"> [leg_class_name]<br /></td></tr>[/leg_class_html]

Cheers,

Jerod
