[mapserver-users] javascript query template examples
Hi mapserver-users, Steve Lime has indeed explained bits of using javascript in CGI query templates, but I'm still lost. Are there any examples showing how to use javascript in a query template to do things like, for example, format the returned query result list to remove duplicate records? Thanks, Greg.

Re: [mapserver-users] WFS returning empty features
I compared your not working mapfile with one i'm using that is working.

Re: [mapserver-users] need help with query
You need some way of presenting the results of the query, hence the use of the template keyword... Glad it was an easy fix though.

I've just committed this to the 5.4 branch, so it will be available in 5.4.2 as for your question, geomtransform replaced the type keyword of rfc45, so the correct answer is to use geomtransform (as per stated in the user documentation) regards, thomas www.camptocamp.com +33 4 79 26 57 97 On Thu, Jun 25, 2009 at 18:29, Charlotte Declercqc.decle...@alkante.com wrote: Actually, there are two ways of drawing polygons as points (positioned in their centroids) : either geotransform or apply the STYLE with TYPE [centroid] as described in http://mapserver.org/development/rfc/ms-rfc-45.html What is your advice ?

Yes, this is works but I don't have any working examples handy. I've tended to create javascript src files on-the-fly rather than just objects.

Re: [mapserver-users] javascript query template examples
Here's one example using new-style templating (recommend MapServer 5.4.1).
We're querying some data
and building a function that can be used to populate a drop down list on a
page. In this case I'm returning
a javascript file on-the-fly. You can also create javascript as part of a
larger HTML page or just plain JSON
or GEOJSON output. Anyway, please ask questions if you need to.
The TEMPLATE:
// MapServer Template
function updateCountyList(element) {
var option;
[resultset layer=counties][feature]
option = new Option([CTY_NAME], [shpext format=$minx,$miny,$maxx,$maxy
precision=0 expand=10%]);
try {
element.add(option, null);
} catch(e) {
element.add(option);
}[/feature][/resultset]
}
The OUTPUTFORMAT:
OUTPUTFORMAT
NAME 'county_select_list'
DRIVER 'TEMPLATE'
MIMETYPE 'text/javascript'
FORMATOPTION 'ATTACHMENT=county_select_list.js'
FORMATOPTION 'FILE=/templates/demo_county_select_list.js'
END
The call to the CGI to run it is:
script
src=http://maps.dnr.state.mn.us/cgi-bin/mapserv54?map=demo.mapqlayer=countiesqformat=county_select_listmode=nquery;/script
The output:
function updateCountyList(element) {
var option;
option = new Option(Clearwater, 304963,5219538,337550,5326697);
try {
element.add(option, null);
} catch(e) {
element.add(option);
}
option = new Option(Aitkin, 434591,5106383,498803,5213702);
try {
element.add(option, null);
} catch(e) {
element.add(option);
}
option = new Option(Chisago, 486969,5013450,529584,5066587);
try {
element.add(option, null);
} catch(e) {
element.add(option);
}
option = new Option(Blue Earth, 387528,4852924,441106,4904495);
try {
element.add(option, null);
} catch(e) {
element.add(option);
}
}

I'm using 5.2.0. Do I need to upgrade?
Anyway, please ask questions if you need to.
Ok!
The TEMPLATE:
// MapServer Template
function updateCountyList(element) {
var option;
...
}
So, where does this template go?
1) there is a TEMPLATE in the WEB section. It seems that if
that line is present, it gets used. I don't think it is
that template.
2) There is DRIVER 'TEMPLATE' in the OUTPUTFORMAT section.
Should the above code be in a file named TEMPLATE?
3) There is a file in the FORMATOPTION under a /templates/
directory that looks suspicious.
4) There is a TEMPLATE in the LAYER section that is used to
indicate that the layer is queryable, and how to format that
layer's data.
The OUTPUTFORMAT:
OUTPUTFORMAT
NAME 'county_select_list'
DRIVER 'TEMPLATE'
MIMETYPE 'text/javascript'
FORMATOPTION 'ATTACHMENT=county_select_list.js'
FORMATOPTION 'FILE=/templates/demo_county_select_list.js'
END
What is the difference in ATTACHMENT and FILE?
The call to the CGI to run it is:
script
src=http://maps.dnr.state.mn.us/cgi-bin/mapserv54?map=demo.mapqlayer=countiesqformat=county_select_listmode=nquery;/script
Aha! qformat=name_of_the_output_format
Thanks,
Wendell
