All * Rights Reserved. * * Contributor(s): pschwartau@netscape.com * Date: 26 November 2000 * * *SUMMARY: Passing a RegExp object to a RegExp() constructor. *This test arose from Bugzilla bug 61266. 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 object obj1 will not include a flag. The flags * parameter for obj2 will be undefined in the sense of not being provided. */ //------------------------------------------------------------------------------------------------- var bug = '61266'; var summary = 'Passing a RegExp object to a RegExp() constructor'; var statprefix = 'Applying RegExp() twice to pattern '; var statsuffix = '; testing property '; var singlequote = "'"; var i = -1; var s = ''; var obj1 = {}; var obj2 = {}; var status = ''; var actual = ''; var expect = ''; var msg = ''; var patterns = 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]$)'; //------------------------------------------------------------------------------------------------- test(); //------------------------------------------------------------------------------------------------- function test() { enterFunc ('test'); printBugNumber (bug); printStatus (summary); for (i in patterns) { s = patterns[i]; status =getStatus(s); obj1 = new RegExp(s); obj2 = new RegExp(obj1); for (prop in obj2) { msg = status + quote(prop); actual = obj2[prop]; expect = obj1[prop]; reportCompare (expect, actual, msg); } } exitFunc ('test'); } function getStatus(regexp) { return (statprefix + quote(regexp) + statsuffix); } function quote(text) { return (singlequote + text + singlequote); }
