Measurement tool

KeisukeNozaki — Wed, 10 Sep 2014 14:39:27 GMT

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.

Keisuke,

did you add "dojo/parser" and variable? Then add parser.parse();

Maybe looking at this example can help? Measurement | ArcGIS API for JavaScript

Yes, I did. Here is a code.

Thank you.

Keisuke,

the issue is you don't put your measurement widget into a Title Pane like in the example. You only put it in the map but there is nothing to house it.

Re: Measurement tool

KeisukeNozaki — Wed, 10 Sep 2014 18:35:06 GMT

Yes, it works.

Would you please tell me which part you changed?

I added "dijit/TitlePane" and the line from 257 to 262.

Thank you.

Re: Measurement tool

TimWitt2 — Wed, 10 Sep 2014 18:47:58 GMT

I had to comment out line 133 to 140.

Added "dijit/TitlePane" to line 74.

Added the lines between 257 and 262.

No problem!

Re: Measurement tool

KeisukeNozaki — Wed, 10 Sep 2014 19:37:52 GMT

Tim,

The code works great.

But I noticed I am not able to draw line or polygon for measurement tool due to popups.

Any workaround?

Re: Measurement tool

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.
