How can I skip the loading of the tiles in OpenLayers?
Question
Actually I need only the full functionality of the map but with no tiles and no requests to the server for them. Can I somehow skip them on the initial load? Is there any default parameter I can set? If not I'll make the patch myself but I'm not sure it's not done yet.

layer = new OpenLayers.Layer.OSM("Transparent","/img/1x1_transparent.png", {numZoomLevels: 19}, {isBaseLayer:true});
只需使用本地的单个微小透明png瓦片即可。

The code I pasted here gives you the openlayers interface with a dummy layer that cannot be loaded. Although I do not see why you would want this, this does show up an empty OpenLayers mapwindow.
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>OpenLayers Standalone</title>
<script src="http://www.openlayers.org/api/OpenLayers.js"></script>
<script type="text/javascript">
var map, layer;
function init(){
map = new OpenLayers.Map( 'map' );
layer = new OpenLayers.Layer.WMS( "dummy",
"",
{layers: 'basic'} );
map.addLayer(layer);
//map.zoomToMaxExtent();
}
</script>
</head>
<body onload="init()">

<div id="map" style="width:250px;height:250px"></div>

Just use vector layers.

Do you actually even have to give the map a layer? I haven't tried doing that.
