[parseInt - ECMA标准]
parseInt (string , radix)The parseInt function produces an integer value dictated by interpretation of the contents of the
string argument according to the specified radix. Leading whitespace in the string is ignored. If radix
is undefined or 0, it is assumed to be 10 except when the number begins with the character pairs 0x
or 0X, in which case a radix of 16 is assumed. Any radix-16 number may also optionally begin with
the character pairs 0x or 0X.
When the parseInt function is called, the following steps are taken:
- 1. Call ToString(string).
- 2. Let S be a newly created substring of Result(1) consisting of the first character that is not a StrWhiteSpaceChar and all characters following that character. (In other words, remove leading white space.)
- 3. Let sign be 1.
- 4. If S is not empty and the first character of S is a minus sign -, let sign be −1.
- 5. If S is not empty and the first character of S is a plus sign + or a minus sign -, then remove the first character from S.
- 6. Let R = ToInt32(radix).
- 7. If R = 0, go to step 11.
- 8. If R < 2 or R > 36, then return NaN.
- 9. If R = 16, go to step 13.
- 10. Go to step 14.
- 11. Let R = 10.
- 12. If the length of S is at least 1 and the first character of S is “0”, then at the implementation's discretion either let R = 8 or leave R unchanged.
- 13. If the length of S is at least 2 and the first two characters of S are either “0x” or “0X”, then remove the first two characters from S and let R = 16.
- 14. If S contains any character that is not a radix-R digit, then let Z be the substring of S consisting of all characters before the first such character; otherwise, let Z be S.
- 15. If Z is empty, return NaN.
- 16. Compute the mathematical integer value that is represented by Z in radix-R notation, using the letters A-Z and a-z for digits with values 10 through 35. (However, if R is 10 and Z contains more than 20 significant digits, every significant digit after the 20th may be replaced by a 0 digit, at the option of the implementation; and if R is not 2, 4, 8, 10, 16, or 32, then Result(16) may be an implementation-dependent approximation to the mathematical integer value that is represented by Z in radix-R notation.)
- 17. Compute the number value for Result(16).
- 18. Return sign × Result(17).
NOTE
parseInt may interpret only a leading portion of the string as an integer value; it ignores any
characters that cannot be interpreted as part of the notation of an integer, and no indication is given
that any such characters were ignored.
When radix is 0 or undefined and the string's number begins with a 0 digit not followed by an x or X,
then the implementation may, at its discretion, interpret the number either as being octal or as being
decimal. Implementations are encouraged to interpret numbers in this case as being decimal.
