my guess is that you are trying to do the query before the map finishes loading. Try moving your query.execute into a map.on layers-add-result event that is why the alert makes it work. It is basically waiting, giving the map enough time to load Thanks Jeff! on it

here is how it works and problems: url looks like http://my.com/test.htm?bldgabbrv=msc,sup3,gsc,rudd,cen query.where = Abbrev = 'MSC' OR Abbrev = 'SUP3' OR Abbrev = 'GSC' OR Abbrev = 'RUDD' OR Abbrev = 'CEN' then queryTask.execute(query, getLocRes); if you look at getLocRes script stops where map.whatever without them script just goes (tested with bunch of console.log) tried for and while but they were not a problem. The Funny thing is when I add alert(); right before queryTask.execute the function works perfect. Does anyone knows what I did wrong? Thanks! *update on jsfiddle when u click run it should select 4 polygons in maroon color

Unfortunately, this doesn't help because your application is simply too big for me to spend time digging through. I really need you to strip out all the unnecessary code and create a sample that highlights your specific issue using jsfiddle.net. Sometimes, when doing this, the issue presents itself, so I suggest giving it a try! Sorry and thank you! thanks Jon I'll try to put my code on jsfiddle soon

You are trying to add an object that does not exist. You want to add 'polyGraphic' to the map.
map.graphics.add(polyGraphic);
Also, make sure you have access to your map object within that functional scope. oops, but anyways that wasn't problem still does same thing and I have full access to the map as well any suggestions? I've tried
function getLocRes(results) {
//map.graphics.clear();
var symbol = new esri.symbol.SimpleFillSymbol(esri.symbol.SimpleFillSymbol.STYLE_SOLID, new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([80, 0, 0]), 2), new dojo.Color([80, 0, 0, 0.5]));
var combinedExtent = new esri.geometry.Extent();
for (var i = 0;i < results.features.length; i++) {console.log("i=",i);
var polyGraphic = new esri.Graphic(results.features, symbol);
map.graphics.add(polyGraphic);
console.log("i=",i);
}
combinedExtent = esri.graphicsExtent(results.features);
map.setExtent(combinedExtent, true);
}
function getLocRes(results) {
//map.graphics.clear();
var symbol = new esri.symbol.SimpleFillSymbol(esri.symbol.SimpleFillSymbol.STYLE_SOLID, new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([80, 0, 0]), 2), new dojo.Color([80, 0, 0, 0.5]));
var combinedExtent = new esri.geometry.Extent();
for (var i = 0;i < results.features.length; i++) {console.log("i=",i);
var polyGraphic = results.features;
polyGraphic.setSymbol(symbol);
map.graphics.add(polyGraphic);
console.log("i=",i);
}
combinedExtent = esri.graphicsExtent(results.features);
map.setExtent(combinedExtent, true);
}
both stop at either map.graphics.add(polyGraphic); or map.graphics.clear(); Thanks Jon

Hi all, function getLocRes(results) {
//map.graphics.clear();
var symbol = new esri.symbol.SimpleFillSymbol(esri.symbol.SimpleFillSymbol.STYLE_SOLID, new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([80, 0, 0]), 2), new dojo.Color([80, 0, 0, 0.5]));
var combinedExtent = new esri.geometry.Extent();
console.log("er",results.features.length);
for (var i = 0;i < results.features.length; i++) {console.log("i=",i);
var polyGraphic = new esri.Graphic(results.features, symbol);
console.log("i=",polyGraphic);
polyGraphic.setSymbol(symbol);
//map.graphics.add(graphic);
}
combinedExtent = esri.graphicsExtent(results.features);
map.setExtent(combinedExtent, true);
} this function is working sort of but when I enable either map.graphics.clear(); or map.graphics.add(graphic); it stops where the code is console.log("i=",i); this shows only 0 when map.graphics.add(graphic); is on if not it doesn't add graphic but shows console.log("i=",i); result until the end Am I missing something here that map.graphics.add(graphic); shouldn't work? dojo.require("dijit.layout.BorderContainer");

dojo.require("esri.map");
dojo.require("esri.dijit.Popup");
dojo.require("esri.dijit.Legend");

like i said, i wasnt sure if you could union a null extent and a valid extent try calling graphicsUtils.graphicsExtent() on your "res" variable to give you the extent https://developers.arcgis.com/javascript/jsapi/esri.graphicsutils-amd.html#graphicsextent Thanks Jeff, finally made it

you cant just append a bunch of geometries together and get the combined extent. try (not sure union will work with an inital null extent) function getLocRes(results) {
map.graphics.clear();
var geom;
var combinedExtent = new Extent();
var symbol = new esri.symbol.SimpleFillSymbol(esri.symbol.SimpleFillSymbol.STYLE_SOLID, new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([80, 0, 0]), 2), new dojo.Color([80, 0, 0, 0.5]));
var res = results.features;
for (var i = 0;i < res.length; i++) {
geom = results.features.geometry.getExtent();
combinedExtent = combinedExtent.union(geom);
var graphic = results.features;
//var graphic = new Graphic(reGeo,symbol);
graphic.setSymbol(symbol);
map.graphics.add(graphic);
}
map.setExtent(combinedExtent , true);
} function getLocRes(results) {
//map.graphics.clear();
var geom;
//
var symbol = new esri.symbol.SimpleFillSymbol(esri.symbol.SimpleFillSymbol.STYLE_SOLID, new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([80, 0, 0]), 2), new dojo.Color([80, 0, 0, 0.5]));
var res = results.features;
var combinedExtent = new esri.geometry.Extent();
for (var i = 0;i < res.length; i++) {
geom = results.features.geometry.getExtent();
combinedExtent = combinedExtent.union(geom);
var graphic = results.features;
//var graphic = new Graphic(reGeo,symbol);
graphic.setSymbol(symbol);
map.graphics.add(graphic);
}
var extent = geom.getExtent();
//alert(map.graphics.graphics.length);
map.setExtent(combinedExtent, true);

function getLocRes(results) { map.graphics.clear(); var geom; var symbol = new esri.symbol.SimpleFillSymbol(esri.symbol.SimpleFillSymbol.STYLE_SOLID, new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([80, 0, 0]), 2), new dojo.Color([80, 0, 0, 0.5])); var res = results.features; for (var i = 0;i < res.length; i++) { geom += results.features.geometry; var graphic = results.features; //var graphic = new Graphic(reGeo,symbol); graphic.setSymbol(symbol); map.graphics.add(graphic); } var extent = geom.getExtent(); map.setExtent(extent, true); } query.where = Abbrev = 'abc' OR Abbrev = 'def' OR Abbrev = 'ghi' selected features are polygons did some stupid thinking like geom += results.features.geometry; but didnt work Can you help me with this?

Hi all, function init() {
var initExtent = new esri.geometry.Extent({"xmin":1076363,"ymin":3109863,"xmax":1084228,"ymax":3113690,"spatialReference":{"wkid":32139}});
var popup = new esri.dijit.Popup({
fillSymbol: new esri.symbol.SimpleFillSymbol(esri.symbol.SimpleFillSymbol.STYLE_SOLID, new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([255,0,0]), 2), new dojo.Color([255,255,0,0.25]))
}, dojo.create("div"));
center = [-90.3378, 39.6177];
zoom = 14;
map = new esri.Map("map",{
basemap: "topo",
infoWindow:popup,
center: center,
zoom: zoom,
sliderStyle: "large"
});
dojo.connect(grid, "onRowClick", onRowClickHandler);
var basemap = new esri.layers.ArcGISDynamicMapServiceLayer("http://localhost:6080/arcgis/rest/services/bt/beta_OnlineMap_Topo/MapServer");
var imageParameters = new esri.layers.ImageParameters();
imageParameters.layerIds = [0,1,2,3,4,6,8];
imageParameters.layerOption = esri.layers.ImageParameters.LAYER_OPTION_HIDE;
Vlayer = new esri.layers.ArcGISDynamicMapServiceLayer("http://localhost:6080/arcgis/rest/services/bt/beta_MapInfo/MapServer", {"imageParameters":imageParameters});
map.addLayers([basemap,Vlayer]); where var basemap= I added var basemap = new esri.layers.ArcGISTiledMapServiceLayer("http://localhost:6080/arcgis/rest/services/bt/beta_OnlineMap_Topo/MapServer"); but entire map didn't work what did I do wrong? dojo.require("esri.layers.TiledMapServiceLayer"); is in the code as well
