JSVAL_TO_OBJECT 编辑
Obsolete since JSAPI 32
This feature is obsolete.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.
Cast a jsval
to a JSObject *
without a type check.
Syntax
JSObject *
JSVAL_TO_OBJECT(jsval v);
Description
JSVAL_TO_OBJECT
casts the argument, v
, to type JSObject *
. As a precondition,
must be true. That is, JSVAL_IS_OBJECT
(v)v
must be either a reference to an object or JSVAL_NULL
. This function is not type-safe: if v
is not an object or JSVAL_NULL
, the behavior is undefined.
To convert a value to an object, use the JS_ValueToObject
function, which has well-defined behavior even when the argument is not an object or null.
