JSVAL_TO_INT 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This feature is obsolete.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.

Converts an integer jsval to a C integer without any type checking or error handling.

Syntax

JSVAL_TO_INT(v)

Description

JSVAL_TO_INT converts a specified integer jsval, v, to the corresponding C integer value. If v is any other type of value, the result is unspecified.

Note that although jsval is an integer type, it must be treated as opaque. The jsval encoding of the integer 4, for instance, is not ((jsval) 4) but some other pattern of bits.

To convert an integer to jsval, use INT_FITS_IN_JSVAL and INT_TO_JSVAL.
