Does current JS API provides topology functions? Thanks.
Shaning,
You are still using Legacy style of coding verses AMD which is what you really should be using in today's day and age (Legacy style of coding is not even supported in JS 4.x api). Here is a very simple sample that shows the contains method. Also you will notice that I have used some of your polygon coordinates with wkid 102100 and they do not plot on the map. So I am not sure your data is 102100.

Rebert: Got an additional prob. (see my email to you). Could you take a look? Thanks.
GREAT HELP! Thanks a LOT!!!
Is the var selected_Poly a Graphic or a Polygon class?
If it is a Graphic which is the normal result of a QueryTask then you just need to use
selected_Poly.geometry.contains(pt);
Robert: Thanks for your response. I use a similar approach to get the polygon feature (termed selected_Poly here). Then I use
var b = selected_Poly.contains(pt);
get Object doesn't support property or method 'contains'. How can the selected feature be cast as a polygon? Thanks.
You are using the JS API so you would use a QueryTask and Query Class to get the feature from your map service.
QueryTask | API Reference | ArcGIS API for JavaScript 3.23
Query | API Reference | ArcGIS API for JavaScript 3.23
Dear Robert: Thanks for your response. In order to use the contains method, I need to get the polygon feature through a URL on a map service. I tried to query a feature on a map service layer. I type attributeName like 'ABC%' in the Where Box, and then * in the Out Fields Box, and make Return Geometry checked.
The URL generated looks like:
http://myArcGISSite/rest/services/theFolder/theLayer/MapServer/1/query?where=attributeName+like%27ABC%01%25%27&text=&objectIds=&time=&geometry=&geometryType=esriGeometryEnvelope&inSR=&spatialRel=esriSpatialRelIntersects&relationParam=&outFields=*&returnGeometry=true&maxAllowableOffset=&geometryPrecision=&outSR=&returnIdsOnly=false&returnCountOnly=false&orderByFields=&groupByFieldsForStatistics=&outStatistics=&returnZ=false&returnM=false&gdbVersion=&returnDistinctValues=false&f=html
I am not sure the returned object is a feature (e.g. polygon). Could you guide me how a feature can be returned through URL? Thanks again.
Then that is definitely possible the Polygon class has a contains method.

Robert: Thanks for your response. What I want to Do a topology validation and see if a point is in a polygon.
Shanning,
Topology is more of a desktop thing, so the best answer is no, but what exactly are you looking for as somethings can be done using the GeometryEngine.
