The substrings are determined by + searching from left to right for occurrences of the given separator; these + occurrences are not part of any substring in the returned array, but serve + to divide up this string value. The separator may be a string of any length. + + As a special case, if the separator is the empty string, the string is split + up into individual characters; the length of the result array equals the + length of the string, and each substring contains one character. + + If the separator is not supplied, then the result array contains just one + string, which is the string. + + When the split method is called with one argument separator, the following steps are taken: + + 1. Call ToString, giving it the this value as its argument. + 2. Create a new Array object of length 0 and call it A. + 3. If separator is not supplied, call the [[Put]] method of A with 0 and + Result(1) as arguments, and then return A. + 4. Call ToString(separator). + 5. Compute the number of characters in Result(1). + 6. Compute the number of characters in the string that is Result(4). + 7. Let p be 0. + 8. If Result(6) is zero (the separator string is empty), go to step 17. + 9. Compute the smallest possible integer k not smaller than p such that + k+Result(6) is not greater than Result(5), and for all nonnegative + integers j less than Result(6), the character at position k+j of + Result(1) is the same as the character at position j of Result(2); + but if there is no such integer k, then go to step 14. + 10. Compute a string value equal to the substring of Result(1), consisting + of the characters at positions p through k1, inclusive. + 11. Call the [[Put]] method of A with A.length and Result(10) as arguments. + 12. Let p be k+Result(6). + 13. Go to step 9. + 14. Compute a string value equal to the substring of Result(1), consisting + of the characters from position p to the end of Result(1). + 15. Call the [[Put]] method of A with A.length and Result(14) as arguments. + 16. Return A. + 17. If p equals Result(5), return A. + 18. Compute a string value equal to the substring of Result(1), consisting of + the single character at position p. + 19. Call the [[Put]] method of A with A.length and Result(18) as arguments. + 20. Increase p by 1. + 21. Go to step 17. + + Note that the split function is intentionally generic; it does not require that its this value be a String + object. Therefore it can be transferred to other kinds of objects for use as a method. + + Author: christine@netscape.com + Date: 12 november 1997 +*/ + +var SECTION = "15.5.4.8-3"; +var VERSION = "ECMA_1"; +startTest(); +var TITLE = "String.prototype.split"; + +writeHeaderToLog( SECTION + " "+ TITLE); + +var TEST_STRING = ""; +var EXPECT = new Array(); + +// this.toString is the empty string. + +new TestCase( SECTION, + "var s = new String(); s.split().length", + 1, + eval("var s = new String(); s.split().length") ); + +new TestCase( SECTION, + "var s = new String(); s.split()[0]", + "", + eval("var s = new String(); s.split()[0]") ); + +// this.toString() is the empty string, separator is specified. + +new TestCase( SECTION, + "var s = new String(); s.split('').length", + 0, + eval("var s = new String(); s.split('').length") ); + +new TestCase( SECTION, + "var s = new String(); s.split(' ').length", + 1, + eval("var s = new String(); s.split(' ').length") ); + +// this to string is " " +new TestCase( SECTION, + "var s = new String(' '); s.split().length", + 1, + eval("var s = new String(' '); s.split().length") ); + +new TestCase( SECTION, + "var s = new String(' '); s.split()[0]", + " ", + eval("var s = new String(' '); s.split()[0]") ); + +new TestCase( SECTION, + "var s = new String(' '); s.split('').length", + 1, + eval("var s = new String(' '); s.split('').length") ); + +new TestCase( SECTION, + "var s = new String(' '); s.split('')[0]", + " ", + eval("var s = new String(' '); s.split('')[0]") ); + +new TestCase( SECTION, + "var s = new String(' '); s.split(' ').length", + 2, + eval("var s = new String(' '); s.split(' ').length") ); + +new TestCase( SECTION, + "var s = new String(' '); s.split(' ')[0]", + "", + eval("var s = new String(' '); s.split(' ')[0]") ); + +new TestCase( SECTION, + "\"\".split(\"\").length", + 0, + ("".split("")).length ); + +new TestCase( SECTION, + "\"\".split(\"x\").length", + 1, + ("".split("x")).length ); + +new TestCase( SECTION, + "\"\".split(\"x\")[0]", + "", + ("".split("x"))[0] ); + +test(); + +function Split( string, separator ) { + string = String( string ); + + var A = new Array(); + + if ( arguments.length < 2 ) { + A[0] = string; + return A; + } + + separator = String( separator ); + + var str_len = String( string ).length; + var sep_len = String( separator ).length; + + var p = 0; + var k = 0; + + if ( sep_len == 0 ) { + for ( ; p < str_len; p++ ) { + A[A.length] = String( string.charAt(p) ); + } + } + return A; +} -- cgit v1.2.3
