Getting 304 errors with OverviewMap

PattyJula — Wed, 11 Dec 2013 02:24:47 GMT

Hi, I have a feature layer and scale bar working properly in a web page with the JavaScript API. When I add an Overview Map, I get 304 errors and can only see an info box when I open the page. My code is below.

<!DOCTYPE html> <html>   <head>      <meta http-equiv="Content-Type" content="text/html; charset=utf-8">     <meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no">     <title>LA Collisions</title>     <link rel="stylesheet" href="http://js.arcgis.com/3.7/js/dojo/dijit/themes/claro/claro.css">     <link rel="stylesheet" href="http://js.arcgis.com/3.7/js/esri/css/esri.css">      <style>          html, body, map { height: 100%; margin: 0; padding: 0; }           #info {          background: #fff;          box-shadow: 0 0 5px #888;          left: 5em;          padding: 0.5em;          position: absolute;           top: 1em;          z-index: 40;       }     </style>      <script>var dojoConfig = { parseOnLoad: true }</script>     <script src="http://js.arcgis.com/3.7/"></script>     <script>        var map;        require([          "esri/map",          "dijit/layout/BorderContainer",          "dijit/layout/ContentPane",          "esri/dijit/InfoWindowLite",         "esri/InfoTemplate",         "esri/layers/FeatureLayer",         "dojo/dom-construct",         "esri/dijit/OverviewMap",          "esri/dijit/Scalebar",         "dojo/parser",         "dojo/domReady!"        ], function (            Map,           InfoWindowLite,           InfoTemplate,           FeatureLayer,           domConstruct,           OverviewMap,    Scalebar,           parser       ) {         parser.parse();         var  map = new Map("map", {           basemap: "topo",           center: [-118.5, 34],           zoom: 11         });                 var scalebar = new Scalebar({           map: map,           // "dual" displays both miles and kilmometers           // "english" is the default, which displays miles           // use "metric" for kilometers           scalebarUnit: "dual"         });        var infoWindow = new InfoWindowLite(null, domConstruct.create("div", null, null, map.root));         infoWindow.startup();         map.setInfoWindow(infoWindow);          var template = new InfoTemplate();         template.setTitle("<b>${OMEGA_NAME}</b>");         template.setContent("<b>Collision Count:</b> ${COUNT_}</br>  <b>Area (square miles):</b> ${AREA_MI}</br>");          //add a layer to the map         var featureLayer = new FeatureLayer("http://arcgis-pjula1gistusc-772545567.us-west-1.elb.amazonaws.com/arcgis/rest/services/LAPD_collisions2/MapServer/0", {            mode: FeatureLayer.MODE_ONDEMAND,           infoTemplate:template,           outFields: ["OMEGA_NAME","REP_DIS", "COUNT_", "AREA_MI", "COLL_RATE"],           opacity:.60         });          map.addLayer(featureLayer);         });          var overviewMapDijit = new OverviewMap({            map: map,           visible: true         });         overviewMapDijit.startup();       });       </script>   </head>     <body>      <div id="info">         Click on a reporting district in Los Angeles to get more information.       </div>   <body class="claro">       <div data-dojo-type="dijit/layout/BorderContainer"           data-dojo-props="design:'headline', gutters:false"          style="width: 100%; height: 100%; margin: 0;">        <div id="map"             data-dojo-type="dijit/layout/ContentPane"             data-dojo-props="region:'center'"             style="overflow:hidden;">    </body>  </html>

Does anyone see what I'm missing? I'm using ArcGIS 10.2 and JavaScript 3.7. The feature layer will probably not be visible when you run this code. Thanks! Patty

try this, i think you are missing the "attachTo"

 var overviewMapDijit = new OverviewMap({
                                        map: map,
                                        attachTo: "bottom-left",
                                        color: " #D84E13",
                                        opacity: .40,
                                        maximizeButton:true
                                    });
                                    overviewMapDijit.startup();

Thanks for the response, Jeff. Yes, I think I was missing the "attachTo" as well. I have added it. I still can only see a few text boxes on the page.

If anyone has other suggestions, please let me know.

Thanks, Patty

Your dependancies are in the wrong order:

       "esri/map",          "dijit/layout/BorderContainer",          "dijit/layout/ContentPane",          "esri/dijit/InfoWindowLite",         "esri/InfoTemplate",         "esri/layers/FeatureLayer",         "dojo/dom-construct",         "esri/dijit/OverviewMap",          "esri/dijit/Scalebar",         "dojo/parser",         "dojo/domReady!"        ], function (            Map,           InfoWindowLite,           InfoTemplate,           FeatureLayer,           domConstruct,           OverviewMap,    Scalebar,           parser       ) {

Change to:

       "esri/map",          "esri/dijit/InfoWindowLite",         "esri/InfoTemplate",         "esri/layers/FeatureLayer",         "dojo/dom-construct",         "esri/dijit/OverviewMap",          "esri/dijit/Scalebar",         "dojo/parser",         "dijit/layout/BorderContainer",          "dijit/layout/ContentPane",          "dojo/domReady!"        ], function (            Map,           InfoWindowLite,           InfoTemplate,           FeatureLayer,           domConstruct,           OverviewMap,    Scalebar,           parser       ) {

That fixed it. Thank you very much, Jon!

also take a look at your code, you have two opening <body> tags

You are right, thanks for pointing that out, Jeff.

Hi all, I have a follow up question. I'm a bit stuck on how to order the dependencies with the JavaScript API. I can get the hover sample working, but when I try to combine it with the geocode an address sample and call a tiled and dynamic layer, the popup does not display. Is there documentation I am missing on how to order the dependencies? I'll probably open a new post if I don't receive a response by tomorrow, since I need to get the the hover tool working for my work.

Thanks!
Patty

the order does not matter, it all loads asynchronously. As above what matters is the order relative to the order in the declare. It has to match perfectly, otherwise you are aliasing the wrong library.

A word of caution, these forums are very casual. They are not official support. If you need an answer "right away", your only option is to call support.

Thanks, Jeff. I will review to see if they match and will call support if I can't get it sorted out. Cheers, Patty

hope you find the error in lining them up. Thats the easy answer 😉

I did! Thank you so much! I had not added "dojo/dom-style" to my JavaScript. Now that it's added, the hover tool works with my geocoder and base maps. Thanks again for talking that out with me! 😄 Patty

Happy to help. I am willing to be almost every developer (myself included) has made that mistake at least once.

Glad you are on the right track.

Thanks Jeff!
Glad everything was taken care of!
Apologies for the delayed response; most of us have been at the DevSummit all week.

sure jon, ill cover for all the developers having fun at the dev conference while I sit here in my cube all week. 🙂

Haha, you should try to make it there next year, Jeff! I attended the first few days - it was great!

Re: Getting 304 errors with OverviewMap

JeffPace — Fri, 14 Mar 2014 17:44:02 GMT

I wish, I have never been.

I do make it to the UC every other year, but County Budgets are very volatile. Plus our Department has gone from 11 people to 5 and our workload has tripled, so not alot of free time.

What I do have I try to spend on here. Lots to learn, Lots to share (mostly from mistakes I have made myself at one point in time)
