Clear query results?

JessicaKnight1 — Wed, 07 Aug 2013 20:12:57 GMT

I am using this sample: https://developers.arcgis.com/en/javascript/jssamples/query_buffer.html and I'm doing something similar, where a user clicks the map and a buffer is drawn and points selected in that buffer. If I use map.graphics.clear(), the buffer gets cleared, but the selected points remain until you click the map again, which causes another buffer and selection. Is there a similar function I can call to get rid of the queried points? Or do I need to reload the map? I did some searching but couldn't find a solution. Thanks.

Since it sounds like you are using a featureLayer, you should just be able to do a clearSelection on it.

In the example you linked, a graphic representation is added to the map which shows the 1 mile buffer. The code "map.graphics.clear" just removes that graphic and doesn't do anything with respect to any selected features.

If you selected features from a feature layer, simply call <your layer>.clearSelection()

Thank you. That works perfectly!
