Showing a splash screen at startup

KenBuja — Mon, 01 Jul 2013 17:27:03 GMT

When a user starts my application, I would like to show a splash screen that would include some background about the project, contact information, required links, etc. I have a Fiddle that shows a splash screen when I click a button, but how do I code that so the splash screen comes up when opening the application?

If I understand your question, I think you want to use dojo.addOnLoad to call your function to show the splash screen. For my script, I created a function init that contained any javascript that I wanted to run as the application loaded. Then I called this init function using the command dojo.addOnLoad(init).

In your case, the javascript would look something like this:
function init() {
dialogWelcome.show();
}
dojo.addOnLoad(init);

You could add more to the init function if you want to as well.

Hope this is what you were looking for!

I'll echo Brittney's suggestion. This is basically what I do, although I fire off my code to display my splash screen in dojo.Ready(). I like using a JQuery modal dialog since they look nicer than Dojo's offerings. The result is something like the attached screenshot.

Thanks, Brittney,

Since dojo.AddOnLoad has been depreciated, I'd like to write this using the newer version. However, I've tried using dojo/ready and the code

    ready(function () {
        dojo.byId("divDialogMessage").innerHTML = parameters.welcomeText;
        dijit.byId("dialogWelcome").show();
    });

but that returns the error "TypeError: dijit.byId(...) is undefined"

and trying "dom.byId("dialogWelcome").show();" give me the error "dom.byId(...) is null"

It turns out that I was overthinking the syntax. This works

    ready(function () {
        divDialogMessage.innerHTML = parameters.welcomeText;
        dialogWelcome.show();
    });

Hi,

You can use esri.show() and esri.hide() to add a splash screen.

Here is a simple code sample which demonstrates the same:

<!DOCTYPE html>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
  <meta http-equiv="X-UA-Compatible" content="IE=7" />
  <title>Splash Screen</title>
  <link rel="stylesheet" href="https://community.esri.com//serverapi.arcgisonline.com/jsapi/arcgis/3.5/js/dojo/dijit/themes/tundra/tundra.css">
  <link rel="stylesheet" href="https://community.esri.com//serverapi.arcgisonline.com/jsapi/arcgis/3.5/js/esri/css/esri.css">
  <style type="text/css">
      html, body
        {
            height: 100%;
            width: 100%;
            margin: 0;
            padding: 0px;
            font-family: helvetica, arial, sans-serif;
            font-size: 90%;
        }

        #mapDiv
        {
            margin: 0px;
            border: solid 1px #B5BCC7;
            height: 100%;
            width: 100%;

        }
  
  </style>

  <script>var dojoConfig = { parseOnLoad: true };</script>
  <script src="//serverapi.arcgisonline.com/jsapi/arcgis/3.5/"></script>
  <script>
    dojo.require("dijit.layout.BorderContainer");
    dojo.require("dijit.layout.ContentPane");
    dojo.require("esri.map");
    dojo.require("esri.layers.FeatureLayer");
    dojo.require("esri.IdentityManager");
 dojo.require("esri.IdentityManagerBase");

    var map;

    function init() {
     
 
      map = new esri.Map("mapCanvas",{
        center: [-107.394, 37.563],
        zoom: 9
      });
   esri.show(splashScreen);
   var basemap = new esri.layers.ArcGISTiledMapServiceLayer("http://services.arcgisonline.com/ArcGIS/rest/services/USA_Topo_Maps/MapServer");
        map.addLayer(basemap);
   dojo.connect(map, "onLoad", function() {
  //esri.hide(splashScreen);
});
     
    }

 function hideSplash(){
  esri.hide(splashScreen);
   map.resize();
      map.reposition();
 }
   
    dojo.ready(init);
  </script>
</head>

<body class="tundra">
  <div data-dojo-type="dijit.layout.BorderContainer" data-dojo-props="design:'headline',gutters:false" style="position:relative;width:100%;height:100%;">
   <div id="mapCanvas" data-dojo-type="dijit.layout.ContentPane" data-dojo-props="region:'center'" style="height:900px;">
  <div data-dojo-type="dijit/Dialog" id="splashScreen" title="Welcome" style="position: absolute; top: 300px; left: 400px; z-index: 100;width:600px">
   <table class="dijitDialogPaneContentArea">
    <tr>
     <td>
      <div id="divDialogMessage">This is the splash text</div>
     </td>
    </tr>
   </table>
        <div class="dijitDialogPaneActionBar">
            <button id="buttonClose" data-dojo-type="dijit/form/Button" type="button" style="align-content: center" onclick="hideSplash();">Close</button>
        </div>
  </div>
 </div>
  </div>

</body>
</html>

Please let me know if it helps!
