JS::CurrentGlobalOrNull 编辑

This article covers features introduced in SpiderMonkey 31

Return the global object for the active function on the context.

Syntax

JSObject *
JS::CurrentGlobalOrNull(JSContext *cx);

Description

JS::CurrentGlobalOrNull() 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.
