JS_GetGlobalForScopeChain 编辑

Obsolete since JSAPI 25
This feature is obsolete.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 1.8.5

Returns the global object for the active function on the context. Renamed to JS::CurrentGlobalOrNull.

Syntax

JSObject *
JS_GetGlobalForScopeChain(JSContext *cx);

Description

JS_GetGlobalForScopeChain() returns the global object for whatever function is currently running on the context. In other words, it returns the global object on the current scope chain.

If there is no JavaScript running on the context, this returns the context's global, i.e., JS_GetGlobalObject(cx). Note that JS_GetGlobalObject() and context globals are becoming obsolete.
