Hi:
Here is part of my codes:
var cars = new OpenLayers.Layer.Vector("cars",
{ strategies : [ new OpenLayers.Strategy.BBOX(),
new OpenLayers.Strategy.Refresh({force: true,
interval:
6000 } )] ,
protocol : new OpenLayers.Protocol.HTTP( {url :
"./xml/data.xml",format : myformat }),
})
/*As the code:I want the layer "cars" refresh itself every 6 seconds,how
can I define the it? and which URL *should I Provide to the
"OpenLayers.Protocol.HTTP( {url : " ? is the format "format:imge/png" would
be OK?
*I just could not understand smoe Properties of the
"OpenLayers.Layer.Vector" ,and there are few examples *for me to make me
understand it. Could you answer my question above?thank you!
*/
