INT_TO_JSVAL 编辑

Obsolete since JSAPI 42
This feature is obsolete.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 a specified integer value to a JS integer value.

Please use JS::Int32Value instead in SpiderMonkey 45 or later.

Syntax

jsval
INT_TO_JSVAL(int32_t i);

Description

INT_TO_JSVAL converts a C integer, i, to a jsval.

Before SpiderMonkey 1.8.5, not all integers can be stored in a jsval; use INT_FITS_IN_JSVAL to test. Starting in SpiderMonkey 1.8.5, jsval can store a full 32-bit integer, so this check isn't needed any longer for 32-bit integers.") }}

If i does not fit into a jsval (see INT_FITS_IN_JSVAL), the behavior is undefined. To convert any number to a jsval, regardless of whether it fits in an int jsval, use JS_NewNumberValue instead.

To convert an integer jsval to a C integer, use JS::ToInt32.
