How to make one layer visible at a time on radiobutton click

tanyabisen — Wed, 07 Dec 2011 08:23:44 GMT

Hello All,

I am new to this javascript API. I have a dynamic map service with 2 layers. I want to make visible one layer at a time on click of corresponding radio button.If one layer is visible the other should automatically be turned off and vice versa.

How do i do this.. Please share with me some sample so that I can proceed ahead with some logic.

Thanks,
Tanya

Hello, this sample should get you started, it should be simple to replace the checkboxs with radiobuttons

function showAdmin(layer){
      debugger
       var arr = [];

       if(document.getElementById('Ward').checked==true){
        arr.push(0);
dynamicMap.setVisibleLayers(arr);
       dynamicMap.refresh();
      }
      if(document.getElementById('Assembly').checked==true){
arr.push(1);
dynamicMap.setVisibleLayers(arr);

       dynamicMap.refresh();
      }
      identifyTask = new esri.arcgis.gmaps.IdentifyTask("http://map2.janaagraha.org/arcgis/rest/services/IJ_Google/MapServer");
      GEvent.addListener(gmap, "click", identify);
      }

Hiya

How did you get this working? did you modify the code suggested by PMhbostic or did you use PMpankajpedram's suggestions?

I am trying to achieve the same thing i.e. radio buttons with feature layers

cheers

Ed
