Hide the undo button when editing shapes with Goog

问题:

Is there a way to hide (ie: don't show, because its annoying) the undo button when editing a shape on a v3 Google Map?

回答1:

Try the undocumented suppressUndo parameter.

It seems to work fine with google.maps.Circle

var c = new google.maps.Circle({
    map: myMap,
    ...
    suppressUndo: true
});
