Let string denote the result of 15 * converting the this value to a string. If regexp.global is false, 16 * return the result obtained by invoking RegExp.prototype.exec (see 17 * section 15.7.5.3) on regexp with string as parameter. 18 * 19 * Otherwise, set the regexp.lastIndex property to 0 and invoke 20 * RegExp.prototype.exec repeatedly until there is no match. If there is a 21 * match with an empty string (in other words, if the value of 22 * regexp.lastIndex is left unchanged) increment regexp.lastIndex by 1. 23 * The value returned is an array with the properties 0 through n-1 24 * corresponding to the first element of the result of each matching 25 * invocation of RegExp.prototype.exec. 26 * 27 * Note that the match function is intentionally generic; it does not 28 * require that its this value be a string object. Therefore, it can be 29 * transferred to other kinds of objects for use as a method. 30 * 31 * 32 * The match function should be intentionally generic, and not require 33 * this to be a string. 34 * 35 */ 36 37 var SECTION = "String/match-004.js"; 38 var VERSION = "ECMA_2"; 39 var TITLE = "String.prototype.match( regexp )"; 40 41 var BUGNUMBER="http://scopus/bugsplat/show_bug.cgi?id=345818"; 42 43 startTest(); 44 45 // set the value of lastIndex 46 re = /0./; 47 s = 10203040506070809000; 48 49 Number.prototype.match = String.prototype.match; 50 51 AddRegExpCases( re, 52 "re = " + re , 53 s, 54 String(s), 55 1, 56 ["02"]); 57 58 59 re.lastIndex = 0; 60 AddRegExpCases( re, 61 "re = " + re +" [lastIndex is " + re.lastIndex+"]", 62 s, 63 String(s), 64 1, 65 ["02"]); 66 /* 67 68 re.lastIndex = s.length; 69 70 AddRegExpCases( re, 71 "re = /([\d]{5})([-\ ]?[\d]{4})?$/; re.lastIndex = " + 72 s.length, 73 s, 74 s.lastIndexOf("0"), 75 null ); 76 77 re.lastIndex = s.lastIndexOf("0"); 78 79 AddRegExpCases( re, 80 "re = /([\d]{5})([-\ ]?[\d]{4})?$/; re.lastIndex = " + 81 s.lastIndexOf("0"), 82 s, 83 s.lastIndexOf("0"), 84 ["02134"]); 85 86 re.lastIndex = s.lastIndexOf("0") + 1; 87 88 AddRegExpCases( re, 89 "re = /([\d]{5})([-\ ]?[\d]{4})?$/; re.lastIndex = " + 90 s.lastIndexOf("0") +1, 91 s, 92 0, 93 null); 94 */ 95 test(); 96 97 function AddRegExpCases( 98 regexp, str_regexp, string, str_string, index, matches_array ) { 99 100 // prevent a runtime error 101 102 if ( regexp.exec(string) == null || matches_array == null ) { 103 AddTestCase( 104 string + ".match(" + regexp +")", 105 matches_array, 106 string.match(regexp) ); 107 108 return; 109 } 110 111 AddTestCase( 112 "( " + string + " ).match(" + str_regexp +").length", 113 matches_array.length, 114 string.match(regexp).length ); 115 116 AddTestCase( 117 "( " + string + " ).match(" + str_regexp +").index", 118 index, 119 string.match(regexp).index ); 120 121 AddTestCase( 122 "( " + string + " ).match(" + str_regexp +").input", 123 str_string, 124 string.match(regexp).input ); 125 126 var limit = matches_array.length > string.match(regexp).length ? 127 matches_array.length : 128 string.match(regexp).length; 129 130 for ( var matches = 0; matches < limit; matches++ ) { 131 AddTestCase( 132 "( " + string + " ).match(" + str_regexp +")[" + matches +"]", 133 matches_array[matches], 134 string.match(regexp)[matches] ); 135 } 136 } 137 138 function AddGlobalRegExpCases( 139 regexp, str_regexp, string, matches_array ) { 140 141 // prevent a runtime error 142 143 if ( regexp.exec(string) == null || matches_array == null ) { 144 AddTestCase( 145 regexp + ".exec(" + string +")", 146 matches_array, 147 regexp.exec(string) ); 148 149 return; 150 } 151 152 AddTestCase( 153 "( " + string + " ).match(" + str_regexp +").length", 154 matches_array.length, 155 string.match(regexp).length ); 156 157 var limit = matches_array.length > string.match(regexp).length ? 158 matches_array.length : 159 string.match(regexp).length; 160 161 for ( var matches = 0; matches < limit; matches++ ) { 162 AddTestCase( 163 "( " + string + " ).match(" + str_regexp +")[" + matches +"]", 164 matches_array[matches], 165 string.match(regexp)[matches] ); 166 } 167 } 168
