the whole query output is determined by sort of template design. It
allows for a certain amount of restructuring of the output by changing
(or extending) the default template, but without modifying directly the
Javascript code that generates the HTML.
It's also possible to do all the parsing on the PHP site, using eg. PHP
templates like smarty, but I never tested it. And it will increase the
amount of data sent to the browser by at least the factor 2.
In general, modifying the "compressed" javascript file is not a good
idea. For any testing set the /src/ directory below "/javascript/" as
the JS location. Then edit the src files, then re-compress everything
uasing the tool under the "utils" part of the SVN. Or, even better, put
your modified JS code in the custom.js file of your config directory
(usually "/config/default/"). This overwrites everything existing with
the same name, best is to use the jQuery $extend(), though.
If you just want to display the number of results in the table header,
add something in custom.js like
$.extend(true, PM.Query,
{
queryTpl:
{
"table":
{"layers":
{"#default":
{"layerHeader":"<div
class=\"pm-info-layerheader\">_p(Layer): ${description} - Number of
results: ${numresults}</div><table class=\"sortable\" cellspacing=\"0\"
cellpadding=\"0\" border=\"0\">",
}
}
}
}
});
(the broken line might need to be in 1 single line). This overwrites
only this specific part by extending the template object "queryTpl" at
just one place.
