Looking at examples and seeing two different ways to require dojo. Whats the difference and which one should I be using? Sorry for the green question... dojo.require("esri.map"); dojo.require("esri.layers.FeatureLayer") Or like this var map; require([ "esri/map", "esri/layers/FeatureLayer" ], function( Map, FeatureLayer )

//Select features within the buffered polygon. To do so we'll create a query to use the buffer graphic
//as the selection geometry.
var query = new Query();
query.geometry = bufferGeometry;
featureLayer.selectFeatures(query, FeatureLayer.SELECTION_NEW, function(results){
var totalPopulation = sumPopulation(results);
var r = "";
r = "<b>The total Census Block population within the buffer is <i>" + totalPopulation + "</i>.</b>";
dom.byId('messages').innerHTML = r;
var data = array.map(results.features, function (feature) {
return {
// property names used here match those used when creating the dgrid
"id": feature.attributes[window.outFields[0]],
"Name": feature.attributes[window.outFields[1]],
"Type": feature.attributes[window.outFields[2]]

});
var memStore = new dojo.store.Memory({

Hi Jay, Here are some samples that has the functionality that you are interested in Buffer and Query https://developers.arcgis.com/javascript/jssamples/query_buffer.html Click on the record in the datagrid, and the appropriate feature gets zoomed and highlighted http://developers.arcgis.com/javascript/samples/fl_zoomgrid/ I hope these samples would give you an idea to move forward. Thanks, Suba Thanks for your help...I was able to get the Buffer and Query working with little issue...now working on trying to get the Results from that Buffer pushed to a Table in my web page (not in the mapDiv itself.) Having some issues with that...could only look at the source code and having issues. Have to some how grab the selected features and put them in an Array and then display the array in HTML? Any further thoughts, hints, examples? Im thinking that I can push teh returned features from within here? But not sure
//Select features within the buffered polygon. To do so we'll create a query to use the buffer graphic
//as the selection geometry.
var query = new Query();
query.geometry = bufferGeometry;
featureLayer.selectFeatures(query, FeatureLayer.SELECTION_NEW, function(results){
var totalPopulation = sumPopulation(results);
var r = "";
r = "<b>The total Census Block population within the buffer is <i>" + totalPopulation + "</i>.</b>";
dom.byId('messages').innerHTML = r;
var items = dojo.map(featureSet.features,function(feature){
return feature.attributes;
});
var data = {
identifier:"ObjectID",
items:items};
store = new dojo.data.ItemFileReadStore({data:data});
grid.setStore(store);
grid.setSortIndex(1,"true"); //sort on the state name
}); Having some sort of HTML Grid here
<div data-dojo-type="dijit.layout.ContentPane" data-dojo-props="region:'left'" style="width:255px">
<table data-dojo-type="dojox.grid.DataGrid" jsid="grid" id="grid" selectionMode="none">

<th field="ObjectID" formatter="makeZoomButton" width="25px">

I was successful in doing this with a Silverlight application I wrote. Looking to do this in Java Script and looking for some thoughts or examples on how to accomplish it in JS. Click on the map Create Buffer at specified distance Use this buffer to query for features that are in it. Return these results to a table in the HTML page itself. Would be nice to have the ability to hover over a record in that table and have it highlight the feature in the map, and visa versa. I was successful in doing this in silverlight but need to move over to JS Anyone have any examples, thoughts etc? Thanks

A little confused. I have been referencing the examples and am putting together a basic Java Script app. I moved to the examples on Printing and am confused with the examples referencing app.map Example: https://developers.arcgis.com/javascript/jssamples/widget_print_esri_request.html
app.map = new esri.Map("map", {
basemap: "hybrid",
center: [-117.447, 33.906],
zoom: 17,
slider: false
}); All examples up to this point have been like this map = new Map("mapDiv", {
basemap: "topo",
center: [-77.4329, 37.5410],
zoom: 7,
slider: true
});
Can someone help me understand this. I have attached my HTML code and Js page if you need a reference as to how I can incorporate this into my app. Any help would be greatly appreciated.
