[Chameleon] LegendTemplateLayerInfo()

[Langlois, Dominic]

Hi Robin,

As far as I know, the function LegendTemplateLayerInfo('[leg_layer_name]')
is
available only when you insert the LegendTemplate widget into your html
template.

The various metadata fields populated in the popup by this function are
'extracted' 
from, on my installation, the mapfile more specifically from the LAYER
section and
METADATA subsection for each layer. Here is an excerpt from my mapfile:

  LAYER
    CONNECTION "http://..."
    CONNECTIONTYPE WMS
      METADATA
        "wms_srs" "EPSG:4326 AUTO:42001 AUTO:42002 AUTO:42003 AUTO:42004
EPSG:4269"
        "wms_onlineresource"  "http://..."
        "wms_name"  "CANIMAGE:CANIMAGE/CANIMAGE"
        "wms_formatlist"  "image/png,image/gif,image/jpeg"
        "wms_format"  "image/png"
        "selected"  "0"
        "wms_server_version"  "1.1.1"
        "wms_title" "CANIMAGE"
        "wms_abstract" "CanImage is an image composed of three spectral
bands originating from
         resampled Landsat 7 orthoimages. They are chosen by the user based
on
         the National Topographic System (NTS) at the 1:50 000 scale. This

  END

Hope this will help.

Hi all,

In some of the Chameleon samples, in the legend template there is the line
<a href="#"
onclick="javascript:LegendTemplateLayerInfo('[leg_layer_name]');">[metadata
name=WMS_TITLE]</a>

Does anyone know where the "LegendTemplateLayerInfo('[leg_layer_name]')"
function is
found?  I have looked through the various legend widgets but I couldn't find
it.  This
is somewhat of an extension of my question yesterday as I am still trying to
find where
to fill the rest of the fields in the popup that this onclick event creates.
Thanks


Robin
