I have gotten a working model to do the addition and removal of layers as
they meet or don't meet the requirements set forth in the wmc based
upon the MaxScaleDenominator as defined in the OGC WMC spec. For example
if you zoom in where the scale is 1:100 and the MaxScaleDenominator is set
to 99 for that layer,
the LayerControl widget will refresh and not show that layer. Then if you
were to zoom into 1:98, the layer would return with the previous value of
hidden or not.
This also works with the MinScaleDenominotor.
Issue to be worked out if possible.
Right now in order to fire the events needed to refresh and remove the
images on LayerControl.xsl I am using an image onerror event and giving it
a faulty image source of "invalid" as seen below.
<img src="invalid" id="vis_{$widgetId}_{$layerId}"
onerror="{$context}.setHidden('{$layerId}',3)"/>
What I would like to do is embedd javascript into the xsl like this
<div>
<script language="JavaScript" type="text/javascript">
<xsl:value-of select="$context"
/><![CDATA[.setHidden("]]><xsl:value-of select="$layerId"
/><![CDATA[",3);]]>
</script>
</div>
This works great in Mozilla. In IE however it doesn't pick up and run the
script. I cannot even get it to do a alert("hello"); within the script
tags
If this image error is an acceptable way to handle it then the code is
functioning, whoever I would like to make it cleaner and do the second
approach.
Any Ideas would be appreciated. If further information is needed please
let me know.-------------------------------------------------------------------------
