迪卡塔-如何刷新地图

Question

I am using the Decarta JS API. I am displaying a map with layers. I want to refresh the map and redraw new layers, but I see no way to do this in the documentation .

Is there a way to refresh the map using the API?

Answer 1

If you just want to refresh a single overlay and not the entire map, you can do this:

myOverlay.render(myMap.tileGrid);

Assuming of course myMap is a deCarta.Core.Map and myOverlay is a deCarta.Core.MapOverlay.

If the size of map container changed, you need to do the following so that the required tiles are loaded after the resize:

myMap.resize();

Answer 2

Using JQuery, I am able to accomplish my desired results by simply removing all children from the designated container the map is added to:

$('#mapContainer').empty();

I feel this is a crude way to handle this functionality and am hoping someone knows a more elegant way.
