dear Readers,thank you reading this question of mine. Using http://developers.arcgis.com/en/javascript/samples/graphics_undoredo/ (without undo and redo), we had created the application and integrating the 2nd link: https://developers.arcgis.com/en/javascript/jssamples/query_buffer.html, we were able to do a map click as explained in the 2nd link to query our layer exposed by webservice.Questions: 1. instead of sending a evt.MapPoint as indicated in the query buffer lnk with a predetermined buffer, how to send a polygon or a polyline intersect - we want the result as it comes out from query buffer.2. another question i had was: in that query_buffer example, example run as-is, returns only Object id for our server - even though i had set query out params = ["*"] and verified that rest service /0 layer queried had all columns exposed in a queriable fashion.I have 1 idea, i can disable the map-click function in the query buffer and try to use the graphics point button to do the selection. but i am not still sure about how to set up the query task to ensure that it does not fail.when i try to send the polyon geometry in the query buffer code, it does not return anything.wanted to see whether there are any examples that i can use to move forward.
function addToMap(geometry) {
var symbol;
toolbar.deactivate();
// map.showZoomSlider();
switch (geometry.type) {
case "point":
symbol = new esri.symbol.SimpleMarkerSymbol();
break;
case "multipoint":
symbol = new esri.symbol.SimpleMarkerSymbol();
break;
case "polyline":
symbol = new esri.symbol.SimpleLineSymbol();
break;
default:
symbol = new esri.symbol.SimpleFillSymbol();
break;
}
var graphic = new esri.Graphic(geometry, symbol);
graphicsDrawnOnScreen = graphic;
map.graphics.add(graphic);
var params = new esri.tasks.BufferParameters();
//params.distances = [100];
params.geometries = graphicsDrawnOnScreen;
// params.unit = esri.tasks.GeometryService.UNIT_METER;
//params.geometries = [evt.mapPoint];
//params.unit = esri.tasks.GeometryService.UNIT_STATUTE_MILE;
geometryService.buffer(params);
geometryService.intersect(graphicsDrawnOnScreen);
toolbarItemClicked == false;
}
i tried the above code without commenting out the above lines.
