ArcGIS - How to add multiple states to existing map?

kaiserislam — Mon, 01 Dec 2014 19:22:14 GMT

I am new to ARCGIS. Can someone show me how can I go about adding 2 states New Jersey and Delaware to the existing code? So that it displays along with New York.

Is there also a wild card option to add all the states?

Kaiser,

If you look at the code there is this line that sets the definition expression for the FeatureLayer:

featureLayer.setDefinitionExpression("STATE_NAME = 'New York'");

You need to adjust this line to add the other states you are interested in, or remove this line if you want all states.

Kaiser,

By the way you will notice that I have moved your thread from the GeoNet Help space to the ArcGIS API for JavaScript‌ space. It is important to post questions in the correct spaces.

Robert Thank you. I was trying something like this but none worked

featureLayer.setDefinitionExpression("STATE_NAME = 'New York', 'New Jersey'");

featureLayer.setDefinitionExpression("STATE_NAME = 'New York'","STATE_NAME = 'New Jersey'");

featureLayer.setDefinitionExpression("STATE_NAME = 'New York'");; featureLayer.setDefinitionExpression("STATE_NAME = 'New Jersey'")

;

The first options render nothing , the second option rendered on new york , third option only NJ .

what is right way to add other states?

Also, If I try to display for the whole of USA removing the featurelayer, defintion(

featureLayer.setDefinitionExpression("STATE_NAME = 'New York'"); )

it only displays half of the USA. screen grab attached below.

Kaiser,

OK, so you need some basic SQL syntax help then.

featureLayer.setDefinitionExpression("STATE_NAME IN( 'New York', 'New Jersey', 'Delaware')");

The reason that removing the DefinitionExpression does not work is you are likely reaching the Map Services max feature output.
