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 had to comment out line 133 to 140.

Added "dijit/TitlePane" to line 74.

Added the lines between 257 and 262.

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.

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.

TimWitt2 · ‎09-10-2014

I had to comment out line 133 to 140.

Added "dijit/TitlePane" to line 74.

Added the lines between 257 and 262.

KeisukeNozaki · ‎09-10-2014

Thank you so much, Tim.

TimWitt2 · ‎09-10-2014

No problem!

KeisukeNozaki · ‎09-10-2014

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?
