The ECMA3 section is: 25* 26* 15.10.3 The RegExp Constructor Called as a Function 27* 28* 15.10.3.1 RegExp(pattern, flags) 29* 30* If pattern is an object R whose [[Class]] property is "RegExp" 31* and flags is undefined, then return R unchanged. Otherwise 32* call the RegExp constructor (section 15.10.4.1), passing it the 33* pattern and flags arguments and return the object constructed 34* by that constructor. 35* 36* 37* The current test will check the first scenario outlined above: 38* 39* "pattern" is itself a RegExp object R 40* "flags" is undefined 41* 42* The flags parameter will be undefined in the sense of not being 43* provided. We check that RegExp(R) returns R - 44*/ 45//------------------------------------------------------------------------------------------------- 46var bug = '61266'; 47var summary = 'Passing (RegExp object,flag) to RegExp() function'; 48var statprefix = 'RegExp(new RegExp('; 49var comma = ', '; var singlequote = "'"; var closeparens = '))'; 50var cnSUCCESS = 'RegExp() returned the supplied RegExp object'; 51var cnFAILURE = 'RegExp() did NOT return the supplied RegExp object'; 52var i = -1; var j = -1; var s = ''; var f = ''; 53var obj = {}; 54var status = ''; var actual = ''; var expect = ''; 55var patterns = new Array(); 56var flags = new Array(); 57 58 59// various regular expressions to try - 60patterns[0] = ''; 61patterns[1] = 'abc'; 62patterns[2] = '(.*)(3-1)\s\w'; 63patterns[3] = '(.*)(...)\\s\\w'; 64patterns[4] = '[^A-Za-z0-9_]'; 65patterns[5] = '[^\f\n\r\t\v](123.5)([4 - 8]$)'; 66 67// various flags to try - 68flags[0] = 'i'; 69flags[1] = 'g'; 70flags[2] = 'm'; 71flags[3] = undefined; 72 73 74 75//------------------------------------------------------------------------------------------------- 76test(); 77//------------------------------------------------------------------------------------------------- 78 79 80function test() 81{ 82 enterFunc ('test'); 83 printBugNumber (bug); 84 printStatus (summary); 85 86 for (i in patterns) 87 { 88 s = patterns[i]; 89 90 for (j in flags) 91 { 92 f = flags[j]; 93 status = getStatus(s, f); 94 obj = new RegExp(s, f); 95 96 actual = (obj == RegExp(obj))? cnSUCCESS : cnFAILURE; 97 expect = cnSUCCESS; 98 reportCompare (expect, actual, status); 99 } 100 } 101 102 exitFunc ('test'); 103} 104 105 106function getStatus(regexp, flag) 107{ 108 return (statprefix + quote(regexp) + comma + flag + closeparens); 109} 110 111 112function quote(text) 113{ 114 return (singlequote + text + singlequote); 115}
