Select features and zoom to layers

SibghatUllah1

I am trying to select highlight features and zoom to selected features layer extent.My code below runs but doesn't highlight any feature.

on(dom.byId("try"), "click", function () {
var queryTask = new QueryTask("http://localhost:6080/arcgis/rest/services/RAEC/MapServer/12");

//build query filter
var que = new Query();
que.returnGeometry = true;
que.outFields = ["FeederID", "OBJECTID"];
que.outSpatialReference = { "wkid": 32640 };
que.where = "FeederID<> ''";
symbol = new SimpleMarkerSymbol();
symbol.setStyle(SimpleMarkerSymbol.STYLE_SQUARE);
symbol.setSize(10);
symbol.setColor(new Color([255,255,0,0.5]));

queryTask.execute(que,showResults);
function showResults(featureSet) {

map.graphics.clear();

var resultFeatures = featureSet.features;

for (var i=0, il=resultFeatures.length; i<il; i++) {
var graphic = resultFeatures;
graphic.setSymbol(symbol);
map.graphics.add(graphic);
}
}
});

OK, That is what does not make sense then.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; query <SPAN class="operator token">=</SPAN> <SPAN class="keyword token">new</SPAN> <SPAN class="token class-name">Query</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">;</SPAN>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; query<SPAN class="punctuation token">.</SPAN>returnGeometry <SPAN class="operator token">=</SPAN> <SPAN class="keyword token">true</SPAN><SPAN class="punctuation token">;</SPAN>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; query<SPAN class="punctuation token">.</SPAN>outFields <SPAN class="operator token">=</SPAN> <SPAN class="punctuation token">[</SPAN><SPAN class="string token">"FeederID"</SPAN><SPAN class="punctuation token">]</SPAN><SPAN class="punctuation token">;</SPAN>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; query<SPAN class="punctuation token">.</SPAN>outSpatialReference <SPAN class="operator token">=</SPAN> map<SPAN class="punctuation token">.</SPAN>spatialReference<SPAN class="punctuation token">;</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

line 2 and line 4 should cause the returned queries geometry to be in the maps spatial reference (WKID 102100).

You could try to manually set it:

query<SPAN class="punctuation token">.</SPAN>outSpatialReference <SPAN class="operator token">=</SPAN> <SPAN class="punctuation token">{</SPAN><SPAN class="string token">"wkid"</SPAN><SPAN class="punctuation token">:</SPAN> <SPAN class="number token">102100</SPAN><SPAN class="punctuation token">}</SPAN><SPAN class="punctuation token">;</SPAN>‍<SPAN class="line-numbers-rows"><SPAN>‍</SPAN></SPAN>

i have already tried both but no success.

query.outSpatialReference={wkid :"32640"}; my map service wkid

query<SPAN class="" style="color: #999999; border: 0px; font-weight: inherit;">.</SPAN>outSpatialReference <SPAN class="" style="color: #a67f59; background: rgba(255, 255, 255, 0.498039); border: 0px; font-weight: inherit;">=</SPAN> map<SPAN class="" style="color: #999999; border: 0px; font-weight: inherit;">.</SPAN>spatialRefernce<SPAN class="" style="color: #999999; border: 0px; font-weight: inherit;">;</SPAN>

Sibghat,

Just add this line with your other query properties:

query<SPAN class="punctuation token">.</SPAN>outSpatialReference <SPAN class="operator token">=</SPAN> map<SPAN class="punctuation token">.</SPAN>spatialReference<SPAN class="punctuation token">;</SPAN>‍‍<SPAN class="line-numbers-rows"><SPAN>‍</SPAN></SPAN>

Dear Robert,

I have make a new html with query.it is running and showing features without adding basemap. when i add

basemap: "topo",
center: [58.871192 , 20.646328],
zoom: 12

The query still runs and results are shown in different area .Something with projection is the error.Please guide

Yes query is running fine and passing geometry object, attribute object and graphics symbols.

RobertScheitlin__GISP

Sibghat,

Have you placed a break point or a console statement in the showResults function to see if you are getting results from your query?
