openlayers - Openlayers map.removeControl() 错误

Question

我无法从地图中删除editingToolBar。我不明白为什么这段代码不起作用：

var editingToolBar = new OpenLayers.Control.Panel({
    displayClass: 'customEditingToolbar',
    allowDepress: true
}); 

var draw = new OpenLayers.Control.DrawFeature(
    newShape, OpenLayers.Handler.Polygon,
    {
       title: "Draw Feature",
       displayClass: "olControlDrawFeaturePolygon",
       multi: true
    }
);

var edit = new OpenLayers.Control.ModifyFeature(newShape, {
    title: "Modify Feature",
    displayClass: "olControlModifyFeature"
});

editingToolBar.addControls([edit, draw]);
map.addControl(editingToolBar);

function stopEditing(){
    map.removeControl(editingToolBar);
}

感谢调试！

最后，错误是editingToolBar变量未定义为全局变量，而是在函数内部，因此无法在stopEditing()函数中访问。

在全局中定义 var：

var editingToolBar;
