Marker Symbol help me please

LouPhan — Tue, 06 Aug 2013 15:13:54 GMT

I want to change the symbol of below example into this code. However, it could not display the new symbol. Can someone help me?

symbol = new esri.symbol.PictureMarkerSymbol({
"angle": 0,
"xoffset": 0,
"yoffset": 12,
"type": "esriPMS",
"url": "http://static.arcgis.com/images/Symbols/Basic/YellowStickpin.png",
"contentType": "image/png",
"width": 24,
"height": 24
});

Here is the example:

      }

 Click on a city once it's highlighted to get an InfoWindow.

Here is my change. It is not working:

Hey,

I think you are trying to use the syntax for javascript api v3.5. You need to use the syntax from the javascript api v1.6 that you are calling out in your app.

http://resources.esri.com/help/9.3/arcgisserver/apis/javascript/arcgis/help/jsapi_start.htm

This code worked in your app:

symbol = new esri.symbol.PictureMarkerSymbol('http://static.arcgis.com/images/Symbols/Basic/YellowStickpin.png', 24, 24);

Hope this helps!

Luci
