Deprecated
This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

Set the runtime-wide check-object-access callback. This function is deprecated. In SpiderMonkey 1.8.1 and later, use JS_SetRuntimeSecurityCallbacks instead.

Syntax

JSCheckAccessOp JS_SetCheckObjectAccessCallback(
    JSRuntime *rt, JSCheckAccessOp acb);

Description

JS_SetCheckObjectAccessCallback sets the runtime-wide check-object-access callback, which is used as the fallback JSClass.checkAccess method for all classes that leave the checkAccess field NULL. This callback is also used to check access to the caller property of function objects (as, for example, when the JavaScript engine creates a stack trace) and to check access from scripts to properties with scripted getters or setters.

JS_SetCheckObjectAccessCallback returns the previous check-object-access callback.
