I got the geometry when I included layerId. function queryResults(featureSet){ var resultSet = featureSet.features; var shape = resultSet[0].geometry; if(shape.type==='polygon'){ var featureExtent=shape.getExtent(); map.setExtent(featureExtent); }else{ alert("Shape is not a polygon"); } Though I set feature Extent to map extent. The slider zooms to the fullest and I get to see only "Map Data Not Available". Why is that? I want the slider to just zoom on the polygon.

I am trying to get the geometry of the polygon using UNIQPOLYID. UNIQPOLYID is the display field. function searchGeometry(polyId){ queryTask = new esri.tasks.QueryTask(URLGoesHere); query = new esri.tasks.Query(); query.returnGeometry = true; query.text = polyId; queryTask.execute(query, queryResults); } function queryResults(featureSet){ alert(featureSet.features); //undefined //Should get the geometry of the feature and zoom into it. } "featureSet.features" is undefined in my queryResults(featureSet). How should I get the the feature with the provided polyId so that I can zoom in to the geometry.

I know that I can zoom to a polygon when it is clicked by doing this identifyParams.geometry = evt.mapPoint; identifyParams.mapExtent = map.extent; identifyTask.execute(identifyParams, function(result) { var i; var polyId= new Array(); for(i=0; i<result.length;i++){ polyId=result.feature.attributes["UNIQPOLYID"]; } But I do not want to do it upon clicking on the map. When the user enters the polygon id in a text box, I want to zoom and show that polygon on the screen.

I have a text box where I have the polygon Id like, "id_of_the_polygon_12345" . Is it possible to get its extent on the map and zoom into it? I have figured out how to do it upon clicking on the map. But could not figure how to do the same knowing my poly Id.

I achieved the result using the following code. esriConfig.defaults.map.slider.top = "200px"; Thanks, Prasanna

Hi, I am using this map https://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer Is there a way to make the scale to appear on the left-middle of the screen? By default it appears at left-top. Thanks Prasanna

I solved it by adding a layer on to the map. var tiledMapServiceLayer = new esri.layers.ArcGISTiledMapServiceLayer("http://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer"); map.addLayer(tiledMapServiceLayer); Thanks Prasanna

Hi, When I click on the map, I get a push pin at that location. I am centering it currently using the code map.centerAt(cPoint); Is there a way to position that push pin at a desired location on the screen(Say, at "500,500")? Thanks Prasanna

Please do explain me the meaning of these statements. bldgResults = {displayFieldName:null,features:[]}; parcelResults = {displayFieldName:null,features:[]}; These are present in the addToMap(idResults, evt) method of the sample given in the link http://help.arcgis.com/en/webapi/javascript/arcgis/help/jssamples_start.htm#jssamples/find_drilldown.html Also please do let me know if this would get me the "UNIQPOLYID" from feature. identifyTask.execute(identifyParams, function(result) { var polyID = result.feature.attributes["UNIQPOLYID"]; }); Thanks Prasanna

Hi, I have found that I have a webservice method with which I can get the Polygon Id from. But I would need the geometry of the polygon in order to call that method. How will I get the geometry of the polygon? Thanks Prasanna

Hi, I have a base map and a layer on it which has polygons. How should I get the polygon Id of the polygon that is clicked? Thanks Prasanna

Hi, I would like to know how to render a custom map service on the page. I know that doing this would render an ArcGis map service. map = new esri.Map("map"); var tiledMapServiceLayer = new esri.layers.ArcGISTiledMapServiceLayer("https://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer"); map.addLayer(tiledMapServiceLayer); I want one of the custom made map service to be placed as the URL. How should I achieve that? Thanks Prasanna

Hi, I need to display a mapservice other than that of arcGis. I know this will render my browser with an ArcGis map. map = new esri.Map("map"); var tiledMapServiceLayer = new esri.layers.ArcGISTiledMapServiceLayer("http://wiwauk4ovlgsw03.itservices.sbc.com/arcgis/rest/services/IGLOO_Maps/IGLOO_SupportMap/MapServer"); map.addLayer(tiledMapServiceLayer); I want to replace the URL(bold) with some other URL which is not offered by ArcGis. How should i do that? Thanks Prasanna

Hi schlot, The error persists even if I put it inside quotes. I did a workaround to make it work. I globally declared a Javascript Array, stored the string in it and passed the index of the array through the info template. With that index, I can access my content from the array. Thanks Prasanna

Hi, I have an info template like this. infoTemplate=new esri.InfoTemplate("<div align='center'><input type='button' value='Use this location' onclick='test(x,y,z)'></div>"); I have defined x,y,z as: x=5; y=10; z="Sairam"; I am getting an error on my browser as " 'Sairam' is undefined". When I pass only numeric values, it works fine. But if i pass a String, i get this undefined error. Could some one tell me how i could pass a String as a parameter on this info template button onclick function? Thanks Prasanna
