1.11 + File Name: 15.5.4.8-2.js
1.12 + ECMA Section: 15.5.4.8 String.prototype.split( separator )
1.13 + Description:
1.14 +
1.15 + Returns an Array object into which substrings of the result of converting
1.16 + this object to a string have been stored. The substrings are determined by
1.17 + searching from left to right for occurrences of the given separator; these
1.18 + occurrences are not part of any substring in the returned array, but serve
1.19 + to divide up this string value. The separator may be a string of any length.
1.20 +
1.21 + As a special case, if the separator is the empty string, the string is split
1.22 + up into individual characters; the length of the result array equals the
1.23 + length of the string, and each substring contains one character.
1.24 +
1.25 + If the separator is not supplied, then the result array contains just one
1.26 + string, which is the string.
1.27 +
1.28 + When the split method is called with one argument separator, the following steps are taken:
1.29 +
1.30 + 1. Call ToString, giving it the this value as its argument.
1.31 + 2. Create a new Array object of length 0 and call it A.
1.32 + 3. If separator is not supplied, call the [[Put]] method of A with 0 and
1.33 + Result(1) as arguments, and then return A.
1.34 + 4. Call ToString(separator).
1.35 + 5. Compute the number of characters in Result(1).
1.36 + 6. Compute the number of characters in the string that is Result(4).
1.37 + 7. Let p be 0.
1.38 + 8. If Result(6) is zero (the separator string is empty), go to step 17.
1.39 + 9. Compute the smallest possible integer k not smaller than p such that
1.40 + k+Result(6) is not greater than Result(5), and for all nonnegative
1.41 + integers j less than Result(6), the character at position k+j of
1.42 + Result(1) is the same as the character at position j of Result(2);
1.43 + but if there is no such integer k, then go to step 14.
1.44 + 10. Compute a string value equal to the substring of Result(1), consisting
1.45 + of the characters at positions p through k1, inclusive.
1.46 + 11. Call the [[Put]] method of A with A.length and Result(10) as arguments.
1.47 + 12. Let p be k+Result(6).
1.48 + 13. Go to step 9.
1.49 + 14. Compute a string value equal to the substring of Result(1), consisting
1.50 + of the characters from position p to the end of Result(1).
1.51 + 15. Call the [[Put]] method of A with A.length and Result(14) as arguments.
1.52 + 16. Return A.
1.53 + 17. If p equals Result(5), return A.
1.54 + 18. Compute a string value equal to the substring of Result(1), consisting of
1.55 + the single character at position p.
1.56 + 19. Call the [[Put]] method of A with A.length and Result(18) as arguments.
1.57 + 20. Increase p by 1.
1.58 + 21. Go to step 17.
1.59 +
1.60 + Note that the split function is intentionally generic; it does not require that its this value be a String
1.61 + object. Therefore it can be transferred to other kinds of objects for use as a method.
