Measurement tool

KeisukeNozaki · ‎09-10-2014

I am trying to add measurement tool to my existing code.

What I did was:

1. add "esri/dijit/Measurement" and variable

2. add the following code after loading feature layer

//dojo.keys.copyKey maps to CTRL on windows and Cmd on Mac., but has wrong code for Chrome on Mac

var snapManager = map.enableSnapping({

snapKey: has("mac") ? keys.META : keys.CTRL

});

var layerInfos = [{

layer: parcelsLayer

}];

snapManager.setLayerInfos(layerInfos);

var measurement = new Measurement({

map: map

}, dom.byId("measurementDiv"));

measurement.startup();

3. add <div id="measurementDiv"></div> in the end

However, the measurement tool does not display.

Please let know what is missing.

Thank you.

I'll take a look tomorrow.

I had to upgrade you to 3.10.

I had to stop your tracking on line 100 and 101.

I removed your legacy code, now your application is AMD.

I added lines 234 to 246.
