The ECMA3 section is: 25* 26* 15.10.4.1 new RegExp(pattern, flags) 27* 28* If pattern is an object R whose [[Class]] property is "RegExp" and 29* flags is undefined, then let P be the pattern used to construct R 30* and let F be the flags used to construct R. If pattern is an object R 31* whose [[Class]] property is "RegExp" and flags is not undefined, 32* then throw a TypeError exception. Otherwise, let P be the empty string 33* if pattern is undefined and ToString(pattern) otherwise, and let F be 34* the empty string if flags is undefined and ToString(flags) otherwise. 35* 36* 37*The current test will check the second scenario outlined above: 38* 39* "pattern" is itself a RegExp object R 40* "flags" is NOT undefined 41* 42* This should throw an exception ... we test for this. 43* 44*/ 45//------------------------------------------------------------------------------------------------- 46var bug = '61266'; 47var summary = 'Negative test: Passing (RegExp object, flag) to RegExp() constructor'; 48var statprefix = 'Passing RegExp object on pattern '; 49var statsuffix = '; passing flag '; 50var cnFAILURE = 'Expected an exception to be thrown, but none was -'; 51var singlequote = "'"; 52var i = -1; var j = -1; var s = ''; var f = ''; 53var obj1 = {}; var obj2 = {}; 54var patterns = new Array(); 55var flags = new Array(); 56 57 58// various regular expressions to try - 59patterns[0] = ''; 60patterns[1] = 'abc'; 61patterns[2] = '(.*)(3-1)\s\w'; 62patterns[3] = '(.*)(...)\\s\\w'; 63patterns[4] = '[^A-Za-z0-9_]'; 64patterns[5] = '[^\f\n\r\t\v](123.5)([4 - 8]$)'; 65 66// various flags to try - 67flags[0] = 'i'; 68flags[1] = 'g'; 69flags[2] = 'm'; 70 71 72 73//------------------------------------------------------------------------------------------------- 74test(); 75//------------------------------------------------------------------------------------------------- 76 77 78function test() 79{ 80 enterFunc ('test'); 81 printBugNumber (bug); 82 printStatus (summary); 83 84 for (i in patterns) 85 { 86 s = patterns[i]; 87 88 for (j in flags) 89 { 90 f = flags[j]; 91 printStatus(getStatus(s, f)); 92 obj1 = new RegExp(s, f); 93 obj2 = new RegExp(obj1, f); // this should cause an exception 94 95 // WE SHOULD NEVER REACH THIS POINT - 96 reportFailure(cnFAILURE); 97 } 98 } 99 100 exitFunc ('test'); 101} 102 103 104function getStatus(regexp, flag) 105{ 106 return (statprefix + quote(regexp) + statsuffix + flag); 107} 108 109 110function quote(text) 111{ 112 return (singlequote + text + singlequote); 113}
