Question

How to check if the map tiles are loaded?

I need to know whether all map tiles are loaded on to the OpenLayers map as html contents.... Is there any method to find out or function in openlayers to find out for how much percentage the map tiles are loaded.......

Answer 1

see the Layer Load Monitoring sample for some ideas.

layer.events.register("loadend", layer, function() {
  this.logEvent("Load End. Grid:" + this.grid.length + "x" + this.grid[0].length);
});
