Hi all,Here what I am trying to do:1) My overall goal is to query an extent and to extract data by this extent. I can successfully achieve the first part.2) Here is my issue: The Dynamic layer queried has a schema that wont work with the GP "Extract data". Here are the default fields I need, these fields are the default for any feature set created:
Fields:
FID ( type: esriFieldTypeOID , alias: FID )
Id ( type: esriFieldTypeInteger , alias: Id )
Shape_Length ( type: esriFieldTypeDouble , alias: Shape_Length )
Shape_Area ( type: esriFieldTypeDouble , alias: Shape_Area )
Features: None.
3) The solution that I am trying to implement is very close to what this person was trying to implement on this thread. My basic understanding of this is to gather all graphics, push them into a brand new feature set and then use it as an AOI.4) My code that works but return an empty shapefile or values:
function executeQueryTask(county) {
var county = document.getElementById("sel_county").value
var queryTask = new QueryTask("http://webgisdevint1/arcgis/rest/services/Alex_Try/Counties/MapServer/0");
var query = new Query();
query.returnGeometry = true;
query.outFields = ["FMNAME_UC"];
query.where = "FMNAME_UC = '" + county + "'";
query.outSpatialReference = map.spatialReference;
queryTask.execute(query);
var clipLayers = [];
if (registry.byId("layer1").get("checked")) {
clipLayers.push("Counties");
}
if (registry.byId("layer2").get("checked")) {
clipLayers.push("SRA");
}
if (registry.byId("layer3").get("checked")) {
clipLayers.push("Burn");
}
if (clipLayers.length === 0) {
alert("No layers to clip, please select a layer you would like to clip...");
return;
}
graphic = new Graphic();
graphic.geometry = esri.graphicsExtent(map.graphics.graphics);
var clipFeatureSet = new FeatureSet();
clipFeature = [];
dojo.forEach(map.graphics.graphics, function(graphic){
//if (graphic.geometry.type ="polygon")
clipFeature.push (graphic);
});
clipFeatureSet.features = clipFeature;
var params = {
"Layers_to_Clip": clipLayers,
"Area_of_Interest": clipFeatureSet,
"Feature_Format": registry.byId("formatBox").get("value")
};
domStyle.set(loading, "display", "inline-block");
gp.submitJob(params, completeCallback, statusCallback, function (error) {
alert(error);
domStyle.set(loading, "display", "none");
});
};
Any idea is more than welcome!Alex
