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This feature is obsolete.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.

This article covers features introduced in SpiderMonkey 1.8.1

JS_EnterCrossCompartmentCall has been removed in bug 786068. Use JS_EnterCompartment instead.

Enter a different compartment on the given context, so that objects in that compartment can be accessed.


JSCrossCompartmentCall *
JS_EnterCrossCompartmentCall(JSContext *cx, JSObject *target);
Name Type Description
cx JSContext * The context on which a cross-compartment call is needed.
target JSObject *

The object in a different compartment to be accessed. This implicitly identifies the compartment to be entered.


Every JSContext has a current compartment. Any access to an object in a different compartment must be bracketed by calling JS_EnterCrossCompartmentCall and JS_LeaveCrossCompartmentCall.

On success, JS_EnterCrossCompartmentCall returns a pointer to a JSCrossCompartmentCall object that must be passed to JS_LeaveCrossCompartmentCall. Otherwise it returns NULL.
