As an example of JavaScript in a GetFeatureInfo response, I can show you:
http://ogc.bgs.ac.uk/cgi-bin/TFL-PSI/ows?language=eng&REQUEST=GetFeatureInfo&SERVICE=WMS&VERSION=1.3.0&LAYERS=GBR_Stoke-on-Trent_ESA_EN_5k_psi_TS&STYLES=&FORMAT=image/png&BGCOLOR=0xFFFFFF&TRANSPARENT=TRUE&CRS=EPSG:4326&BBOX=53.0052235378464,-2.28573545848794,53.1251768672774,-2.13175281574312&WIDTH=1086&HEIGHT=846&QUERY_LAYERS=GBR_Stoke-on-Trent_ESA_EN_5k_psi_TS&i=337&j=255&info_format=text/html&;
The chart that shows is plotted by JavaScript in the response according to
values retrieved.

//-->

...
Creating a location to put the chart
<tr><td id="[Id]_chart1" class="tschart" title="Time series chart for selected
point" style="display:none;"></td></tr>
...
Adding the JavaScript that do the plotting:
<script type="text/javascript"><!--
$("#[Id]_chart1:hidden").show();
var plot1 = $.jqplot('[Id]_chart1', [[Id]_tsline], {
title:'Time series plot for selected point',
axes:{xaxis:{renderer:$.jqplot.DateAxisRenderer}},
series:[{lineWidth:3, markerOptions:{style:'circle'}}]
}); // -->
</script>
Hope this helps

Hello,
Is it possible to do numeric calculations with the result of a GetFeatureInfo?
Some layers have an area field in square meters but I want to display it to the
user in acres or hectares. It would be nice not having to create a second
attribute column in my source layer just for that.
I am using an html template at layer level to output the results of the query.
Mapserver 7.0.4
Thank you,
Patrice

Hello Patrice,
I would prefer to save the data in a database using a view to create the
additional field (I haven't tried, but I think even spatialite is possible as
mapserver-deatasource?)
Another way would be to use scripting
- calculate the value with javascript within the template-html or
- use server-side processing within the template

Could you point me in the right direction for the solutions you proposed? I
like the idea of do calculations client-side with javascript, however, I didn't
figure out how to fetch the value withina <script> tag in the template.
