You could instantiate your excel logic in python using python dictionaries as the look-up lists... Or pre-calculate everything in excel and join it to your spatial layers. ... View more

jberg, From what I gather you are attempting to select a series of points from a layer and return them if they are contained by a polygon drawn by a user? I doubt the following logic will be the most elegant way but my approach would be as follows using points stored in a GraphicsLayer: var polygon:Polygon = new Polygon(); //This would be the user's created polygon. for(var i:int = 0; i<=graphicsLayer.numGraphics;i++){   if(!polygon.contains(MapPoint((graphicsLayer.graphicsProvider as Graphic).geometry)){      graphic.visible = false;   }else{      graphic.visible = true;   }; }; ...

David, Are you successfully getting your "Locations" data to load into an object? I assume you have a feature Layer with the field [Location] containing a link for each feature. When you select (e.g. RollOver, click, etc.) a feature you should get it (i.e. event.target ). This should be returned to you as a graphic although you may need to cast it to a graphic. In the event.target graphic, get the attributes (event.target).attributes. Then get the position of the [Location] attribute with something like "attributes[0]" or attributes["Location"]. This should return the link. Unfortunately I usually code in flex and only vaguely familiar with the javascript API (although esri tells me there web api's are all similar). So i have described a logic I would use. I apologize for not solving your issue! ... View more

Let's see: I had in error in my earlier code (extra brackets). var Att = {Location: "Location"} function hideDiv() {     if (Att.Location.toString() == ''){ //if the Att object's location is cast to a string and is empty          document.getElementById("testdiv").style.visibility= 'hidden'; //hide the div     }else{ //if it is not an empty string document.getElementById("testdiv").style.visibility='visible';//show the div     }; }; in your code: Att.eLocation.toString() "eLocation" is not a property of the Att object. Are you able to debug your JavaScript by using something like firebug plugin in firefox? ... View more

Try using "while" loops as well. These are often faster than "for" loops. Also try using direct OS calls like os.listdir(). ... View more

Reading through some of the API, this may work: var infoTemplate = new esri.InfoTemplate(); infoTemplate.setContent( '<b>Station:</b><a href="http://${Corner Point Identifier}.pdf">Descriptive Text</a>' ); If this is a valid path: "http://${Corner Point Identifier}.pdf" ... View more

David, Sorry-- misunderstood. So you would like to know if the location string (part of the URI) is empty? If you have the div: <div id="testdiv"> <a href="{'http://000.000.000.000/flexviewers/app/'+Att.Location.toString()}"  target=_blank>Location</a> </div> Then in javascript you'll use similar code as above, but add a check to the location: You will use the equality operator '=='. var Att = {Location: "Location"} function hideDiv() {     if (Att.Location.toString() == ''){ //if the Att object's location is cast to a string and is empty          document.getElementById("testdiv").style.visibility= 'hidden';} //hide the div     }else{ //if it is not an empty string document.getElementById("testdiv").style.visibility='visible';}//show the div     }; } Is this closer to what your asking? ...

Have you tried casting it to a Layer and calling the refresh() method on it. This should reload the Layer. ... View more

Maybe something like this? I think the Att variable is an object. You need to get the value of 'Location' out of the Att object. So your script would be something like: var Att = {Location: "Location"} function hideDiv() { if (Att = '') {document.getElementById("testdiv").style.visibility= 'hidden';} }else{ document.getElementById("testdiv").style.visibility='visible';} }; } Where you have the "testdiv" already added to the DOM somewhere. <div id="testdiv"> <a href="{'http://000.000.000.000/flexviewers/app/'+Att.Location.toString()}"  target=_blank>Location</a> </div> ...

Nortonsig, I think you'll get a FeatureSet returned from a Query function. Iterate through the features using a "for" loop and extract the needed field values from the attributes into an array. Use this array to create your chart... ... View more

You can put the link in an html anchor tag (<a>) and add it to the htmltext attribute of a text tag (<mx:Text>). Put the text tag as a child in the infoWindow (map.infoWindow). Then call the show/hide methods on the infoWindow when the user interacts with a feature. ... View more
