I need to remove a geometry from the map. It may be a marker, circle, polyline etc. I don't see any method like remove, clear or destroy. I already know how to clear everything on the map but this is not what I need.
I would like to remove it with javascript.
If the Graphic is added directly to the map, you can just call map.graphics.remove(the_graphic), where the_graphic is the graphic that you want to remove.
You can also call map.graphics.clear(); to remove all graphics added in this way.
If you have added graphics to a particular graphics layer, then you need to remove the graphic from that particular layer, by calling something like gLayer.remove(the_graphic) where gLayer is your graphic layer and the_graphic is the graphic that you want to remove.
For completeness sake, if you want to remove all graphics contained in the map, you can use the following function:
function clearGraphics() {
//first remove all graphics added directly to map
map.graphics.clear();
//now go into each graphic layer and clear it
var graphicLayerIds = map.graphicsLayerIds;
var len = graphicLayerIds.length;
for (var i = 0; i < len; i++) {
var gLayer = map.getLayer(graphicLayerIds[i]);
//clear this Layer
gLayer.clear();
}
}
The trick is to know the graphic that coresponds to the geometry.
So you only have to use :
map.graphics.remove(your_graphic);
It sounds like you're working with graphics elements on the map, which were added using the Editor toolbar.
In this case, the graphics are probably located in the map's default graphicsLayer, or in another graphics layer. See map.graphicsLayerIds for a method to iterate through these layers.
Once you have a pointer to the graphic via its layer, you can then delete it.
