Hoover Javascript API

akashmagoon — Thu, 26 Apr 2012 21:34:18 GMT

I added onto a sample.

The circle represent pushpin and when you click on it, it will open a info window.

How can i make the info window popup by hovering.

I tried the Mouseover call but it didnt work.

Heres my current code.. Please edit it. Thanks in advance.

Your code has the onMouseOver event listening to the Map itself - you need to listen to the graphics:

function init() {
 var initExtent = new esri.geometry.Extent({"xmin":-14052134,"ymin":5562249,"xmax":-13179529,"ymax":5897349,"spatialReference":{"wkid":102100}});
 map = new esri.Map("map",{extent:initExtent});
 var basemap = new esri.layers.ArcGISTiledMapServiceLayer("http://server.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer");
 map.addLayer(basemap);
 
 dojo.connect(map, "onLoad", function() {
  
  var points = { 
   "points": [[-122.63,45.51],[-122.56,45.51],[-122.56,45.55],[-122.62,45.00],[-122.59,45.53]], 
   "spatialReference": ({ "wkid": 4326 })
  };
  var mp = new esri.geometry.Multipoint(points);
  var wm_mp = esri.geometry.geographicToWebMercator(mp);
  
  var sms = new esri.symbol.SimpleMarkerSymbol();
  var infoTemplate = new esri.InfoTemplate("Bob","Lives in the USA"); 
  var graphic = new esri.Graphic(wm_mp, sms, '', infoTemplate);
  map.graphics.add(graphic);
  
  dojo.connect(map.graphics, "onMouseOver", function(evt) {
                  var g = evt.graphic;
                  map.infoWindow.setContent(g.getContent());
                  map.infoWindow.setTitle(g.getTitle());
                  map.infoWindow.show(evt.screenPoint,map.getInfoWindowAnchor(evt.screenPoint));
               });
               dojo.connect(map.graphics, "onMouseOut", function() {map.infoWindow.hide();} );
 
 });
}

I have made some changes to your code to enable hover on the points. Please see if this works for you.
