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. * * This file tests cases in which regexp.global is false. Therefore, * results should behave as regexp.exec with string passed as a parameter. * */ var SECTION = "String/match-002.js"; var TITLE = "String.prototype.match( regexp )"; // the regexp argument is not a RegExp object // this is not a string object AddRegExpCases( /([\d]{5})([-\ ]?[\d]{4})?$/, "/([\d]{5})([-\ ]?[\d]{4})?$/", "Boston, Mass. 02134", 14, ["02134", "02134", undefined]); AddGlobalRegExpCases( /([\d]{5})([-\ ]?[\d]{4})?$/g, "/([\d]{5})([-\ ]?[\d]{4})?$/g", "Boston, Mass. 02134", ["02134"]); // set the value of lastIndex re = /([\d]{5})([-\ ]?[\d]{4})?$/; re.lastIndex = 0; s = "Boston, MA 02134"; AddRegExpCases( re, "re = /([\d]{5})([-\ ]?[\d]{4})?$/; re.lastIndex =0", s, s.lastIndexOf("0"), ["02134", "02134", undefined]); re.lastIndex = s.length; AddRegExpCases( re, "re = /([\d]{5})([-\ ]?[\d]{4})?$/; re.lastIndex = " + s.length, s, s.lastIndexOf("0"), ["02134", "02134", undefined] ); re.lastIndex = s.lastIndexOf("0"); AddRegExpCases( re, "re = /([\d]{5})([-\ ]?[\d]{4})?$/; re.lastIndex = " + s.lastIndexOf("0"), s, s.lastIndexOf("0"), ["02134", "02134", undefined]); re.lastIndex = s.lastIndexOf("0") + 1; AddRegExpCases( re, "re = /([\d]{5})([-\ ]?[\d]{4})?$/; re.lastIndex = " + s.lastIndexOf("0") +1, s, s.lastIndexOf("0"), ["02134", "02134", undefined]); test(); function AddRegExpCases( regexp, str_regexp, string, index, matches_array ) { // prevent a runtime error if ( regexp.exec(string) == null || matches_array == null ) { AddTestCase( string + ".match(" + regexp +")", matches_array, string.match(regexp) ); return; } AddTestCase( "( " + string + " ).match(" + str_regexp +").length", matches_array.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 ); var limit = matches_array.length > string.match(regexp).length ? matches_array.length : string.match(regexp).length; for ( var matches = 0; matches < limit; matches++ ) { AddTestCase( "( " + string + " ).match(" + str_regexp +")[" + matches +"]", matches_array[matches], string.match(regexp)[matches] ); } } function AddGlobalRegExpCases( regexp, str_regexp, string, matches_array ) { // prevent a runtime error if ( regexp.exec(string) == null || matches_array == null ) { AddTestCase( regexp + ".exec(" + string +")", matches_array, regexp.exec(string) ); return; } AddTestCase( "( " + string + " ).match(" + str_regexp +").length", matches_array.length, string.match(regexp).length ); var limit = matches_array.length > string.match(regexp).length ? matches_array.length : string.match(regexp).length; for ( var matches = 0; matches < limit; matches++ ) { AddTestCase( "( " + string + " ).match(" + str_regexp +")[" + matches +"]", matches_array[matches], string.match(regexp)[matches] ); } }
