I noticed that when using a GIcon sprite under IE6, the browser
fetches the sprite each time I add a marker to the map. Here's the
code (a bit reduced) that I use to create the GIcon and then render it
to the map. Is there something I can change to avoid multiple sprite
fetches in Internet Explorer 6?
//returns an image-like GIcon based on a sprite
function spriteIcon(attr) {
var myicon = new GIcon(G_DEFAULT_ICON);
myicon.sprite = {image:"/site_media/images/sprite.png", left:
(attr.offset*16), top:0};
myicon.iconSize = new GSize(16,16);
myicon.iconAnchor = new GPoint(8,8);
myicon.shadow = null;
return myicon;
}
//render a set of nodes to the map
GMap2.prototype.renderNodes = function(nodes) {
...
for (var i = 0; i < nodes.length; ++i) {
var node = nodes[i];
this.waypoints[node.i] = makeWaypoint(node);
attr = getNodeType(node.a)
var myicon = spriteIcon(attr);
var marker = new GMarker(waypoint.point, myicon);
...
}
}
