I am trying to give users the ability to select features from a specific feature layer, buffer that selection and query another feature layer using the geometries from the buffer. I want results from the first selection to be sent to one datagrid and results from the second query to be sent to a different datagrid. I think I am really close - the way I have it set up now is the user can draw a box to select features (points in this case). When the drawing ends, it select features within the drawn extent, performs a buffer at a set distance on those features, and uses the buffer extent to select features from a polygon layer. This all works just fine however, the issue I am having is with the two datagrids. For some reason, data from the first selection is being pushed to both datagrids.
Here is a bit of JS:
dojo.connect(map, "onLoad", function(map) {
//initialize the toolbar
toolBar2 = new esri.toolbars.Draw(map);
dojo.connect(toolBar2, "onDrawEnd", onDrawEnd);
});
var featureLayerUrl = "http://summitmaps.summitoh.net/arcgis/rest/services/DOES_Mercator/MapServer/2";
featureLayer = new esri.layers.FeatureLayer(featureLayerUrl, {
mode: esri.layers.FeatureLayer.MODE_SELECTION,
outFields: ["UNAME", "INSTALLYR", "DNAME", "STREET", "EASEMENT", "INVERT", "OWNERSHIP"]
});
featureLayer.setSelectionSymbol(new esri.symbol.SimpleMarkerSymbol().setSize(8).setColor(new dojo.Color([160, 214, 238])));
map.addLayer(featureLayer);
function onDrawEnd(extent) {
var newStore = new dojo.data.ItemFileReadStore({
data: {
identifier: "",
items: []
}
});
var grid = dijit.byId("manholeGrid");
manholeGrid.setStore(newStore);
toolBar2.deactivate();
var query = new esri.tasks.Query();
query.geometry = extent;
featureLayer.selectFeatures(query, esri.layers.FeatureLayer.SELECTION_NEW, function(features, selectionMethod) {
var items30 = dojo.map(features, function(feature) {
return feature.attributes;
});
var data30 = {
identifier: "OBJECTID",
items: items30
};
var store30 = new dojo.data.ItemFileReadStore({
data: data30
});
var manholeGrid = registry.byId("manholeGrid");
manholeGrid.on("rowclick", onRowClickHandler);
manholeGrid.setStore(store30);
map.setExtent(graphicsUtils.graphicsExtent(featureLayer.getSelectedFeatures()), true);
gsvc = new GeometryService("http://summitmaps.summitoh.net/arcgis/rest/services/Utilities/Geometry/GeometryServer");
var graphics = featureLayer.graphics;
var selectedGeoms = graphicsUtils.getGeometries(graphics);
var params = new BufferParameters();
params.geometries = selectedGeoms;
params.distances = [500];
params.unit = GeometryService.UNIT_FOOT;
params.outSpatialReference = map.spatialReference;
gsvc.buffer(params, showBuffer);
function showBuffer(geometries) {
var symbol = new SimpleFillSymbol(SimpleFillSymbol.STYLE_SOLID, SimpleLineSymbol(SimpleLineSymbol.STYLE_SOLID,
new Color([0, 0, 255, 0.65]), 2
),
new Color([0, 0, 255, 0.35])
);
arrayUtils.map(geometries, function(geometry) {
var graphic = new Graphic(geometry, symbol);
map.graphics.add(graphic);
});
queryTaskNew = new esri.tasks.QueryTask("http://summitmaps.summitoh.net/arcgis/rest/services/Cadastral/Parcels/MapServer/0");
var queryNew = new esri.tasks.Query();
queryNew.returnGeometry = true;
queryNew.outFields = ["PARID", "ADDR"];
queryNew.geometry = geometries[0];
queryTaskNew.execute(queryNew, showResults300);
function showResults300(featureSet) {
var resultFeatures = featureSet.features;
for (var i = 0, il = resultFeatures.length; i < il; i++) {
var items300 = dojo.map(features, function(feature) {
return feature.attributes;
});
var data300 = {
identifier: "OBJECTID",
items: items300
};
var store300 = new dojo.data.ItemFileReadStore({
data: data300
});
var grid = registry.byId("parcelGrid");
grid.on("rowclick", onRowClickHandler);
grid.setStore(store300);
}
}
};
});
And here is the HTML as it pertains to the above code:
<div data-dojo-type="dijit/layout/ContentPane" title="Manhole">
<input type="text" id="doesManholeText" value="BA15" />
<button id="doesManholeSearch" data-dojo-type="dijit.form.Button" type="button" data-dojo-attach-point="button">Search</button>
<button data-dojo-type="dijit.form.Button" onClick="toolBar2.activate(esri.toolbars.Draw.EXTENT);">Select</button>
<button id="clearManholeGrid" data-dojo-type="dijit.form.Button" type="button" data-dojo-attach-point="button">Clear</button>
<span id="manhole-result-count"></span>
<table data-dojo-type="dojox/grid/DataGrid" data-dojo-id="manholeGrid" id="manholeGrid" style="height: 340px" data-dojo-props="rowsPerPage:'100', rowSelector:'20px'">
<thead>
<tr>
<th field="UNAME">UNAME</th>
<th field="INSTALLYR">Install Year</th>
<th field="DNAME">DNAME</th>
<th field="STREET">Street</th>
<th field="EASEMENT">Easement</th>
<th field="INVERT">Invert</th>
<th field="OWNERSHIP">Ownership</th>
</tr>
</thead>
</table>
</div>
<div id="bottom" data-dojo-type="dojox/layout/ExpandoPane" title="Click the Arrow to Minimize this Panel" data-dojo-props="title: 'Parcel Search', splitter:true, startExpanded: false, region:'bottom'" style="height: 300px;">
<div data-dojo-type="dijit/layout/ContentPane" title="Selected Parcels">
<table data-dojo-type="dojox.grid.DataGrid" data-dojo-id="parcelGrid" id="parcelGrid" style="height: 300px" data-dojo-props="rowsPerPage:'100', rowSelector:'20px'">
<thead>
<tr>
<th field="PARID">Parcel #</th>
<th field="ADDR">Address</th>
</tr>
</thead>
</table>
</div>
</div>
Can anyone see why I can't get results from the second query, in this case, "queryTaskNew" into the appropriate datagrid?
Any help is much appreciated!!
