ArcGIS JavaScript API: Legend and checkbox

HabG_ — Wed, 01 Oct 2014 10:28:33 GMT

Hi All,

I have a web map with three feature layers and one dynamic map layer, and when I use the legend code it is displaying only the three feature layers. What do I need to display all four layers in the legend. Also how do I add a checkbox to display only the checked layers. Here is the code I'm using.

Thanks

//add the legend
  map.on("layers-add-result", function (evt) {
        var layerInfo = arrayUtils.map(evt.layers, function (layer, index) {
          return {layer:layer.layer, title:layer.layer.name};
        });
        if (layerInfo.length > 0) {
          var legendDijit = new Legend({
            map: map,
            layerInfos: layerInfo
          }, "legendDiv");
          legendDijit.startup();
        }

Hi Hab,

Here is an example you can refer to that has an ArcGISDynamicServiceLayer in the legend, and a checkbox next to each layer to toggle it on/off.

I am using this code below in a file mapOverlay.html but it does not work. Could you give me any suggestion? I don't know what template my application was developed.

Jake, I know this is quite old but figured I would give this a shot in asking a question. Can you put a legend under each checkbox as they are checked. I don't want a different tab to show the legend I was users to see the legend for that particular layer as they turn the layer on and off underneath it. Thanks and hopefully you get this reply.
