How do you find the number of points in a polygon? PointCollection is the object in ArcGIS api for Silverlight. This object is not working in ArcGIS api for javascript 3.19
Here's one way to do it. Given a polygon (feature), this returns the point count for each of a polygon's rings
<SPAN class="keyword token">for</SPAN> <SPAN class="punctuation token">(</SPAN><SPAN class="keyword token">var</SPAN> i<SPAN class="punctuation token">;</SPAN> i <SPAN class="operator token"><</SPAN> feature<SPAN class="punctuation token">.</SPAN>geometry<SPAN class="punctuation token">.</SPAN>rings<SPAN class="punctuation token">.</SPAN>length<SPAN class="punctuation token">;</SPAN> i<SPAN class="operator token">++</SPAN><SPAN class="punctuation token">)</SPAN> <SPAN class="punctuation token">{</SPAN> console<SPAN class="punctuation token">.</SPAN><SPAN class="token function">log</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="string token">"Ring"</SPAN> <SPAN class="operator token">+</SPAN> i <SPAN class="operator token">+</SPAN> <SPAN class="string token">": "</SPAN> <SPAN class="operator token">+</SPAN> feature<SPAN class="punctuation token">.</SPAN>geometry<SPAN class="punctuation token">.</SPAN>rings<SPAN class="punctuation token">[</SPAN>i<SPAN class="punctuation token">]</SPAN><SPAN class="punctuation token">.</SPAN>length <SPAN class="operator token">+</SPAN> <SPAN class="string token">" points"</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">;</SPAN> <SPAN class="punctuation token">}</SPAN><SPAN class="line-numbers-rows"><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN></SPAN>
It works. Thanks.
I am converting an ArcGIS api for Silverlight application to ArcGIS api for JavaScript 3.19 using MVC5. Why is the JavaScript 3.19 intellisense not displaying properly?
