The ECMA3 section is: * * 15.10.4.1 new RegExp(pattern, flags) * * If pattern is an object R whose [[Class]] property is "RegExp" and * flags is undefined, then let P be the pattern used to construct R * and let F be the flags used to construct R. If pattern is an object R * whose [[Class]] property is "RegExp" and flags is not undefined, * then throw a TypeError exception. Otherwise, let P be the empty string * if pattern is undefined and ToString(pattern) otherwise, and let F be * the empty string if flags is undefined and ToString(flags) otherwise. * * *The current test will check the first scenario outlined above: * * "pattern" is itself a RegExp object R * "flags" is undefined * * We check that a new RegExp object obj2 defined from these parameters * is morally the same as the original RegExp object obj1. Of course, they * can't be equal as objects - so we check their enumerable properties... * * In this test, the initial RegExp obj1 will include a flag. The flags * parameter for obj2 will be undefined in the sense of not being provided. */ //----------------------------------------------------------------------------- var gTestfile = '15.10.4.1-3.js'; var BUGNUMBER = '61266'; var summary = 'Passing a RegExp object to a RegExp() constructor'; var statprefix = 'Applying RegExp() twice to pattern '; var statmiddle = ' and flag '; var statsuffix = '; testing property '; var singlequote = "'"; var i = -1; var j = -1; var s = ''; var obj1 = {}; var obj2 = {}; var status = ''; var actual = ''; var expect = ''; var msg = ''; var patterns = new Array(); var flags = new Array(); // various regular expressions to try - patterns[0] = ''; patterns[1] = 'abc'; patterns[2] = '(.*)(3-1)\s\w'; patterns[3] = '(.*)(...)\\s\\w'; patterns[4] = '[^A-Za-z0-9_]'; patterns[5] = '[^\f\n\r\t\v](123.5)([4 - 8]$)'; // various flags to try - flags[0] = 'i'; flags[1] = 'g'; flags[2] = 'm'; flags[3] = undefined; //------------------------------------------------------------------------------------------------- test(); //------------------------------------------------------------------------------------------------- function test() { enterFunc ('test'); printBugNumber(BUGNUMBER); printStatus (summary); for (i in patterns) { s = patterns[i]; for (j in flags) { f = flags[j]; status = getStatus(s, f); obj1 = new RegExp(s, f); obj2 = new RegExp(obj1); reportCompare (obj1 + '', obj2 + '', status); } } exitFunc ('test'); } function getStatus(regexp, flag) { return (statprefix + quote(regexp) + statmiddle + flag + statsuffix); } function quote(text) { return (singlequote + text + singlequote); }
