switching views

Or the legend template could be set up to control groups and you could have two groups in your map file ...

Hi,

Do you have a LegendTemplate widget in your application? This may simplify the JavaScript to use.

If you don't want to use JavaScript, I think it should be relatively easy to build a simple and custom widget that simply turn on/off the two layers via php/mapscript. You can check the web documentation for examples of widget customization.

Hello fellow chameleon users.
I would to seek your help regarding turning on and off layers.
In my map, I am aiming to have two views: a graphical view and an aerial view. How do I make it such that a user will only have to click a link in the page and will transform the view from a graphical one (shape files) to an aerial one (aerial pphotograph). I have seen a campus map of MIT (http:// whereis.mit.edu/map-jpg <http://mail.up.edu.ph/horde/util/go.php? url=http%3A%2F%2Fwhereis.mit.edu%2Fmap- jpg&Horde=37be496d6af69b5651d122cd40b96a90>) that employs this kind of method.
I believe the principle here is that I only have to turn off the graphical layers and then
turn on the aerial photograph layer when the view is switched... But how will I do it? How do I make a link in my html file that will turn on the photo layer and turn off the
others, and vice versa?
I tried having two sets of map files.. one for shape file layers and the other for the
aerial photograph.. However, I think it was not useful because when the view is switched, the scale at which the map is displayed before the switch was not preserved.
I consulted Jacob Delfos about this and he said the solution is though the use of javascripts. But I am nowhere at javascript.
Please help.
By the way I'm using MS4W.
Thanks in advance.
Regards,
Jojin
