Have a look at <a class="moz-txt-link-freetext" href="http://www.geomoose.org/docs/user_extensions.html">http://www.geomoose.org/docs/user_extensions.html</a>
and varoius pages on the wiki
(<a class="moz-txt-link-freetext" href="http://www.geomoose.org/wiki/index.php/Main_Page">http://www.geomoose.org/wiki/index.php/Main_Page</a>), and the
functions defined in the geomoose.js file. The functions in the
file are the user-accessible "official" GeoMOOSE API. These
resources may give you a few ideas.<br>
<br>
In one of my sites, I needed to get the value of the selected item
in a combo box and use it for input value in services.<br>
<br>
My combo box is a little complicated; the important bits are
id="GA_SelectedImage" and the first part of the option value
(1,2,3,etc)<br>
<br>
<div id="control-panel"><br>
<center><br>
Image:<br>
<select id="GA_SelectedImage"
onchange="GeoMOOSE.UX.registered_extensions.GA_ImageOps.prototype.zoomToImage(this.value);"><br>
<option value="">Choose Image:</option><br>
<option
value="1:-2172034,13348962,-1027313,14456993:Landsat/p230r005_20010703">L7
2001-07-03 p230-r005</option><br>
<option
value="2:-2564614,12851203,-1468813,13863841:Landsat/p230r006_20010703">L7
2001-07-03 p230-r006</option><br>
<option
value="3:-2564614,12851203,-1468813,13863841:Landsat/p231r006_20010608">L7
2001-06-08 p231-r006</option><br>
<br>
<br>
I have a service called "add_polygon" (see the Feature Editor doc)
where one of the inputs is defined as "imageid":<br>
<br>
<service name="add_polygon"><br>
<input type="ga_get_imageid" name="feature:imageid"
value="0"/><br>
<br>
<br>
Note the type tag value refers to my custom input type. And [I
think?] since its outside the the "<step>" tag it is not shown
to the user. If I wanted to make it visible and changeable by the
user I could have done:<br>
<br>
<service name="add_polygon"><br>
<br>
<step type="input"><br>
<input type="ga_get_imageid" name="feature:imageid"
value="0"/><br>
<br>
<br>
I defined the type by creating a Javascript file in the extensions
folder containing:<br>
<br>
GeoMOOSE.Services.InputType.GetImageID =
OpenLayers.Class(GeoMOOSE.Services.InputType, {<br>
MAPBOOK_NAME: "ga_get_imageid",<br>
<br>
getValue: function() {<br>
var selection = document.getElementById('GA_SelectedImage');<br>
var theValue =
selection.children[selection.selectedIndex].value;<br>
<br>
var aParams = theValue.split(':');<br>
var id = aParams[0];<br>
return id;<br>
}<br>
});<br>
<br>
And my JavaScript file is loaded in my main html page:<br>
<script type="text/javascript"
src="extensions/GeoAnalytic_Custom.js"></script> <br>
<br>
So basically, when the service is invoked, it processes the input
types, and calls the ga_get_imageid function. The function finds
the combo box control, gets the selected value, and returns the
important part of the value. GeoMoose sets the service's input type
value to that returned value and passes it to the target URL of the
service.<br>
<br>
Somewhat complicated, but it separates my custom JavaScript from the
standard GeoMOOSE (making updates much easier).<br>

style="font-size: 10pt; font-family: Arial;">I’m looking
to dynamically control some of the
parameter values in mapbook.xml. In a nutshell, I’ve been
able to save a
selected town name by holding it in a hidden input in
index.html. So what I’d
like to do, in the search_parcels service, is to update a
parameter with that
town name. I believe it would make use of some
javascript, but I’m not
quite sure how to do it. Any suggestions? Any more
clarification needed?<o:p></o:p></span></font></p>
