Entry: JSVAL_IS_INT (Macro)
Summary: Determines if a specified value is a JS integer data type.
Syntax:
JSVAL_IS_INT(v)
Description:
Use JSVAL_IS_INT to determine if a given JS value, v, is a JS integer value. If the type tag for v is JSVAL_INT and is not JSVAL_VOID, JSVAL_IS_INT evaluates to true. Otherwise, it evaluates to false. These return types are C values, not JS Boolean values.
Example:
The following code snippet illustrates how a JavaScript variable, MyItem, is conditionally tested in an if statement to see if it is a JS integer data type.
if (JSVAL_IS_INT(MyItem)) {
. . .
}
