ArcGIS JavaScript: delete all graphics that intersect a polygon?

JerryGarcia — Sun, 09 Nov 2014 02:58:30 GMT

How do you manage graphics with the ArcGIS JavaScript API?

Specifically, I want to delete all graphics that intersect a polygon. How do I do that?

I have graphics in Feature Layers.

Thanks!

Jerry,

You would loop through the Graphics Layers graphics to see if the graphics.geometry is contained in the test polygon. Polygon class has a contain method that take a geometry as a parameter. If the polygon contains the geometry then you use the GraphicsLayers.remove method that take a graphics as its parameter. Hope this helps.
