Let string denote the * result of converting the this value to a string. String is searched * for the first occurrence of the regular expression pattern regexp if * regexp.global is false, or all occurrences if regexp.global is true. * * The match is performed as in String.prototype.match, including the * update of regexp.lastIndex. Let m be the number of matched * parenthesized subexpressions as specified in section 15.7.5.3. * * If replaceValue is a function, then for each matched substring, call * the function with the following m + 3 arguments. Argument 1 is the * substring that matched. The next m arguments are all of the matched * subexpressions. Argument m + 2 is the length of the left context, and * argument m + 3 is string. * * The result is a string value derived from the original input by * replacing each matched substring with the corresponding return value * of the function call, converted to a string if need be. * * Otherwise, let newstring denote the result of converting replaceValue * to a string. The result is a string value derived from the original * input string by replacing each matched substring with a string derived * from newstring by replacing characters in newstring by replacement text * as specified in the following table: * * $& The matched substring. * $‘ The portion of string that precedes the matched substring. * $’ The portion of string that follows the matched substring. * $+ The substring matched by the last parenthesized subexpressions in * the regular expression. * $n The corresponding matched parenthesized subexpression n, where n * is a single digit 0-9. If there are fewer than n subexpressions, “$n * is left unchanged. * * Note that the replace 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. */ AddTestCase( "NO TESTS EXIST", "PASSED", "Test not implemented"); test();
