This is probably pretty easy but I can't seem to get what I'm doing wrong. I have a function, kicked off via a button click, that queries a particular layer, and then does some additional queries & data retrieval against three other layers. Basically, I have one location and I want to extract information from three other datasets that overlap its spatial extent. Anyways, what I've tried to do is an initial query to my layer which has my spatial location (using an FID which I pass to the function). Once I query that layer, I was to "save" the feature to a variable so I can quickly use it in my subsequent queryTask calls. Here's my simple code: function getProjectReport(theFid) { var theParam = theFid.split(","); var query = new esri.tasks.Query(); query.where = "FID=" + theParam[0]; query.outFields = ["*"]; query.returnGeometry = true; var theGraphic; //Specify the appropriate point/line map service depending on what was clicked switch (theParam[1]) { case "point": var queryTask = new esri.tasks.QueryTask("URL #1"); break; case "polyline": var queryTask = new esri.tasks.QueryTask("URL #2"); break; } queryTask.execute(query,function(featureSet) { dojo.forEach(featureSet.features, function(feature) { theGraphic = feature; }); }); console.log(theGraphic.attributes.PROJECT); } Now, the queryTask finds my record but when it gets to my "console.log" line, it errors out and tells me that my variable theGraphic is undefined. I've defined my variable at the beginning of my function so why doesn't my assignment persist after the end ofmy forEach loop? How do I fix this so I can re-use theGraphic later on in my function? Thanks again! Steve

I decided to re-publish my service with the standalone table tucked inside it. Just seems like the easiest way to do it. Thanks again for the ideas! Steve

John/Mike, Thanks for responding. My table is located in a FileGeoDatabase so I can certainly publish it via ArcGIS Server. How do I publish JUST the table in ArcGIS Server? I tried adding the table to a blank MXD and publishing the MXD but the table isn't listed in the published service. Worst comes to worse, I could add the table into another existing map service and then access it through that service but I'd like to know how to publish a stand alone table.

I'm looking for some guidance on how to proceed with a certain task I'd like to implement which would use a standalone table. My app works with Census data and so once the user clicks on a cenus tract, I'd like to load up some additional information (based on the census tract number) which is stored in a separate, stand alone table. That's what I want to do- now how do I do that? After reviewing the API, I'm not sure how you "add" the table as a layer so that you can query it. The table will have a one to many relationship so I can't just join the table to my census tracts feature layer before serving it up as a service. Thanks! Steve

Derek, Unfortunately, the feature layers being used in my map are services on our developmental server so any full code post wouldn't work for you. The good news is that I have got it working. The short story is that I believe the javascript code was fine and I was just missing a parameter on the HTML side of things. I changed my design from a dojo combo box to a dojo FilteringSelect. After making the change, it still didn't work. After some head scratching, I modified my HTML Input tag to read <input id="cboTipList" dojoType="dijit.form.FilteringSelect" searchAttr="PROJNAME" name="WidgetName" pageSize="12" placeHolder="Select A TIP Project" onChange="zoomRow(dijit.byId('cboTipList').value);"> and it *finally* worked. The key seems to be the "searchAttr" option, which I was originally missing. Whew!

I would second Steve's suggestion about tying the popup to a feature layer. For example, in one of my maps, I define the popup content at the beginning of my initMap() function like this: var removalTemplate = new esri.InfoTemplate(); removalTemplate.setContent('<table cellspacing=\"5\" style=\"font-size:90%\"><tr><td style=\"vertical-align:top\"><b>Road Name:</b></td><td style=\"vertical-align:top\">${Name}</td></tr><tr><td style=\"vertical-align:top\"><b>Snow Removal Priority:</b></td><td style=\"vertical-align:top\">${Priority:formatPriorityLabel}</td></tr></table>'); removalTemplate.setTitle('${Name}'); Next, you specify the template when you create the feature layer: // Define the Snow Removal Route layer theSnowRemovalLayer = new esri.layers.FeatureLayer("URL to feature layer", { mode: esri.layers.FeatureLayer.MODE_ONDEMAND, infoTemplate:removalTemplate, outFields: ["*"], opacity:0.80, visible: false }); Towards the end, but still within the initMap() function, I associate the popup with the specific feature layer: dojo.connect(theSnowRemovalLayer,"onClick",function(evt){ //Listener event for feature selection and the popup info widow var query = new esri.tasks.Query(); query.geometry = pointToExtent(map,evt.mapPoint,15); var deferred = theSnowRemovalLayer.selectFeatures(query,esri.layers.FeatureLayer.SELECTION_NEW); map.infoWindow.resize(map.width * 0.55,map.height * 0.25); map.infoWindow.setFeatures([deferred]); map.infoWindow.show(evt.mapPoint); }); Hopefully that makes sense. Good luck! Steve

Hi Derek, I've tried that line as well with no luck. I should have mentioned that I'm specifying v2.8 of the API since I'm doing the initial development locally and not on a server. This hasn't been a problem with a dojo datagrid so I assumed it wouldn't be a problem with the combo box..

‎09-24-2012

In a web map I'm developing, I want a combo box populated with project names and FID so that once the user selects a project, I can zoom to that project's feature extent. Within my Init() function, I'm using a query task like this: //Push the attributes of the TIP Projects into the combo box var query = new esri.tasks.Query(); query.where = "1=1"; query.outFields = ["*"]; var queryTask = new esri.tasks.QueryTask("my feature layer URL"); queryTask.execute(query,populateCbo); Later down the line, my function "populateCbo" attempts to populate the combo box: function populateCbo(results) { //Populate the dropdown list box with unique values var values = []; var features = results.features; dojo.forEach (features, function(feature) { curProject = feature.attributes.PROJECT; curFid = feature.attributes.FID; values.push({'project':curProject,'fid':curFid}); }); //Sort the values list by project name //values.sort(by('project')); var dataItems = { identifier: 'fid', label: 'project', items: values }; var store = new dojo.data.ItemFileReadStore({data:dataItems}); dijit.byId("cboTipList").store = store; } Everything seems to work just fine until the line which populates the store variable. The dataItems variable has information in it but after stepping through the "store = .." line, the data property for store is still null. Am I not formatting the contents of dataItems properly? I'm not sure why it's not getting populated. Thanks! Steve

Awesome. Thanks, Rich! Your suggestion finally makes it work. Marked as answered. Thanks again! Steve

Hi Rich, I tried adding another dojo connect on the mapPanel but it did not solve the issue: dojo.connect(dijit.byId('mapPanel'), 'resize', function(map) { map.resize; });

I've pieced together a webpage template with a small header, a collapsible left panel (using the dojo ExpandoPane) and the rest of the screen is devoted to the map area. If the browser window's width is changed, the map will resize accordingly. If the ExpandoPane is minimized using the button, the map simply moves left and does not resize to fit the enlarged screen space. It's probably something simple but I can't figure out where I've gone wrong. Anyone out there see my mistake?

There was some code I was looking at this week about infoWindows and keeping them within the visible screen. Maybe this thread can help you. Otherwise, you could try something like this where you base the dimensions on a percentage of the map's overall dimensions: map.infoWindow.resize(map.width * 0.75,map.height * 0.6); Steve

Thanks, John. I marked your response with "answered" since that's an ESRI sample (albeit buried in the hidden corners of ESRIdom). I did not try a comma specifically but I did add the "fieldDelimiter" parameter like in that example and it wasn't honoring it. I had close to 30 unique values I wanted to symbolize and that was A LOT of formatted code in my function. I ended up dumping all of that in favor of using the renderer.AddValue() method which cleaned things up quite a bit and works for me. So, during the JSON import, I just apply a simple marker symbol to the data and then once the FeatureLayer is created, I overwrite the original renderer with the unique values renderer. Everyone's happy! 😄 Steve

I am working on the code to add a FeatureLayer based on a JSON feed. I'm currently using a unique value renderer based on one field in the data and I'm using the style shown in the API documentation for esri.renderer.uniqueValueRenderer(json). Let's say the field I'm currently using categorizes damage (Wind, Flood, Fire, etc) but there is an additional field which indicates severity (Low, Medium, High). I want to now incorporate that second field into my renderer. My current renderer code would look something like this: "drawingInfo": { "renderer": { "type": "uniqueValue", "field1": "Category", "defaultSymbol": { "type": "esriPMS", "url": "a/url/default.gif", "contentType": "image/gif", "width": 18, "height": 18 }, "uniqueValueInfos": [{ "value": "Flood", "symbol": { "type": "esriPMS", "url": "a/url/flood.gif", "contentType": "image/gif", "width": 18, "height": 18 } }, To now incorporate the second field, would I just do the following? "drawingInfo": { "renderer": { "type": "uniqueValue", "field1": "Category", "field2": "severity", "defaultSymbol": { "type": "esriPMS", "url": "a/url/default.gif", "contentType": "image/gif", "width": 18, "height": 18 }, "uniqueValueInfos": [{ "value": "Flood:Low", "symbol": { "type": "esriPMS", "url": "a/url/floodLow.gif", "contentType": "image/gif", "width": 18, "height": 18 } },{ "value": "Flood:Medium", "symbol": { "type": "esriPMS", "url": "a/url/floodMedium.gif", "contentType": "image/gif", "width": 18, "height": 18 } } Thanks again! Steve

Well HALLELUJAH! I have solved the mystery of date formatting! Your suggestion, Rene, still didn't work for me so I kept playing with it. If I manually typed things in within the javascript console, it would work. If I used the same thing within my javascript function, it would not. This got me thinking that perhaps the date returned via the query was a string instead of a number. To test it, I tried adding the "parseInt" function: alert(new Date(parseInt(rowdata.dateCl))); Lo and behold- it now works in Chrome and STILL works in Firefox. Thank god! That was maddening. Thanks again, Rene for helping me out!
