[Chameleon] javascript to turn on a layer worked!!! but...

[JR Santillan]

Hello there again.

I tried the script Julien posted and I found out that the script will only work if the visibility in the LegendTemplate widget is set to "true"... and  if the "checkboxes" in the legend_template.html file is included...

However, the primary reason why I wanted to use a javascript is to avoid displaying the legend in my application that will also avoid the checking and unchecking of the layers in the legend.

Any help out there to work this out?

Thanks again.

Your funciton should look like:

     function becomeAerial()
     {
         for(i=0;document.forms[0].elements['legendlayername[]'][i];i++)
         {
 
if(document.forms[0].elements['legendlayername[]'][i].value=="Aerial")
             {
 
document.forms[0].elements['legendlayername[]'][i].checked=true;
             }
         }
         document.forms[0].submit();
     }

Note that:
- the forms take an 's'
- the access to form elements with '[]' in the names is special.
- in the if() statement, the value should be equal (==) to "Aerial" not 
differ!  ent  (!=).
