By contrast, the \011 in the 17 * regexp should be parsed as a single token: it is the octal escape sequence 18 * for the horizontal tab character '\t' === '\u0009' === '\x09' === '\011'. 19 * 20 * So the regexp consists of 2 characters: <any-character>, <'\t'>. 21 * There is no match between the regexp and the string. 22 * 23 * See the testcase ecma_3/RegExp/octal-002.js for an elaboration. 24 * 25 */ 26 var SECTION = "RegExp/octal-003.js"; 27 var VERSION = "ECMA_2"; 28 var TITLE = "RegExp patterns that contain OctalEscapeSequences"; 29 var BUGNUMBER="http://scopus/bugsplat/show_bug.cgi?id=346132"; 30 31 startTest(); 32 33 AddRegExpCases( /.\011/, "/\\011/", "a" + String.fromCharCode(0) + "11", "a\\011", 0, null ); 34 35 test(); 36 37function AddRegExpCases( 38 regexp, str_regexp, pattern, str_pattern, index, matches_array ) { 39 40 // prevent a runtime error 41 42 if ( regexp.exec(pattern) == null || matches_array == null ) { 43 AddTestCase( 44 regexp + ".exec(" + str_pattern +")", 45 matches_array, 46 regexp.exec(pattern) ); 47 48 return; 49 } 50 AddTestCase( 51 str_regexp + ".exec(" + str_pattern +").length", 52 matches_array.length, 53 regexp.exec(pattern).length ); 54 55 AddTestCase( 56 str_regexp + ".exec(" + str_pattern +").index", 57 index, 58 regexp.exec(pattern).index ); 59 60 AddTestCase( 61 str_regexp + ".exec(" + str_pattern +").input", 62 escape(pattern), 63 escape(regexp.exec(pattern).input) ); 64 65 AddTestCase( 66 str_regexp + ".exec(" + str_pattern +").toString()", 67 matches_array.toString(), 68 escape(regexp.exec(pattern).toString()) ); 69 70 var limit = matches_array.length > regexp.exec(pattern).length 71 ? matches_array.length 72 : regexp.exec(pattern).length; 73 74 for ( var matches = 0; matches < limit; matches++ ) { 75 AddTestCase( 76 str_regexp + ".exec(" + str_pattern +")[" + matches +"]", 77 matches_array[matches], 78 escape(regexp.exec(pattern)[matches]) ); 79 } 80 81} 82
