JS ClearScope

Obsolete since JSAPI 18
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

Remove all properties associated with an object.


void JS_ClearScope(JSContext *cx, JSObject *obj);
Name Type Description
cx JSContext * The context in which to clear the object. Requires request. In a JS_THREADSAFE build, the caller must be in a request on this JSContext.
obj JSObject * Object from which to delete all properties.


JS_ClearScope removes all of obj's own properties, except the special __proto__ and __parent__ properties, in a single operation. Properties belonging to objects on obj's prototype chain are not affected.

To remove a single property from an object, use JS_DeleteProperty. To remove a single array object element, use JS_DeleteElement.
