[Chameleon] javascript to turn on a layer

[JR Santillan]

Hello all.

I am trying to use javascript to turn on a layer (an aerial photograph) but its not working. Jacob Delfos gave a rough draft of the script and i experimented on it. (I am not knowlegdeable in Javascript.)

In the map file, the layer name for the aerial photograph is "Aerial".

Here's the script:

            <a href="javascript:becomeAerial()">Go to aerial mode</a>

            <script>
            function becomeAerial()
            {
                
                for(i=0;i<document.form[0].legendlayername[].length;i++)
                    {
                        if(document.form[0].legendlayername[i].value!="Aerial")
                            {
                                document.form[0].legendlayername[i].checked=true;
                            }
                    }
                document.form[0].submit();
            }
            </script>


and the Legend Layer Template is:


[leg_layer_html order=ascending opt_flag=15]
  <tr bgcolor="#ffffff">
    <td><input type="radio" name="my_legend" onclick="CWCSelectLayer('[leg_layer_name]', true)"[if name=selected value=1] CHECKED[/if] ></td>
    <td align="center" width=20><input type="checkbox" name="legendlayername[]" 
value="[leg_layer_name]"
    [if name=layer_status oper=eq  value=1]CHECKED[/if]
    [if name=layer_status oper=eq value=2]CHECKED[/if]></td>
    <td><img src="[leg_icon width=20 height=18]" width="20" height="20"</td>
    [if name=wms_name oper=isnull]
    <td><a href="#" onclick="javascript:LegendTemplateLayerInfo('[leg_layer_name]');"><span class="label">[leg_layer_name]</span></a></td>
  </tr>
    [/if]
    [if name=wms_name oper=isset]
    <td><a href="#" onclick="javascript:LegendTemplateLayerInfo('[leg_layer_name]');"><span class="label">[metadata name=WMS_TITLE]</span></a></td>
  </tr>
    [/if]
[/leg_layer_html]

I hope somebody could help. Thanks.
