Let string denote the result of * converting the this value to a string. If regexp.global is false, * return the result obtained by invoking RegExp.prototype.exec (see * section 15.7.5.3) on regexp with string as parameter. * * Otherwise, set the regexp.lastIndex property to 0 and invoke * RegExp.prototype.exec repeatedly until there is no match. If there is a * match with an empty string (in other words, if the value of * regexp.lastIndex is left unchanged) increment regexp.lastIndex by 1. * The value returned is an array with the properties 0 through n-1 * corresponding to the first element of the result of each matching * invocation of RegExp.prototype.exec. * * Note that the match 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. */ var SECTION = "String/match-001.js"; var TITLE = "String.prototype.match( regexp )"; // the regexp argument is not a RegExp object // this is not a string object // cases in which the regexp global property is false AddRegExpCases( 3, "3", "1234567890", 1, 2, ["3"] ); // cases in which the regexp object global property is true AddGlobalRegExpCases( /34/g, "/34/g", "343443444", 3, ["34", "34", "34"] ); AddGlobalRegExpCases( /\d{1}/g, "/d{1}/g", "123456abcde7890", 10, ["1", "2", "3", "4", "5", "6", "7", "8", "9", "0"] ); AddGlobalRegExpCases( /\d{2}/g, "/d{2}/g", "123456abcde7890", 5, ["12", "34", "56", "78", "90"] ); AddGlobalRegExpCases( /\D{2}/g, "/d{2}/g", "123456abcde7890", 2, ["ab", "cd"] ); test(); function AddRegExpCases( regexp, str_regexp, string, length, index, matches_array ) { AddTestCase( "( " + string + " ).match(" + str_regexp +").length", length, string.match(regexp).length ); AddTestCase( "( " + string + " ).match(" + str_regexp +").index", index, string.match(regexp).index ); AddTestCase( "( " + string + " ).match(" + str_regexp +").input", string, string.match(regexp).input ); for ( var matches = 0; matches < matches_array.length; matches++ ) { AddTestCase( "( " + string + " ).match(" + str_regexp +")[" + matches +"]", matches_array[matches], string.match(regexp)[matches] ); } } function AddGlobalRegExpCases( regexp, str_regexp, string, length, matches_array ) { AddTestCase( "( " + string + " ).match(" + str_regexp +").length", length, string.match(regexp).length ); for ( var matches = 0; matches < matches_array.length; matches++ ) { AddTestCase( "( " + string + " ).match(" + str_regexp +")[" + matches +"]", matches_array[matches], string.match(regexp)[matches] ); } }
