See, for example, * * http://bugzilla.mozilla.org/show_bug.cgi?id=159849#c11 * http://bugzilla.mozilla.org/show_bug.cgi?id=184107 * * * However, if |x| already has a property |f|, a |with| statement can be * used to modify the value it contains: * * with (x) {f = 1;} * * This should work even if we use a |var| statement, like this: * * with (x) {var f = 1;} * * However, it should NOT work if we use a |function| statement, like this: * * with (x) {function f() {}} * * Instead, this should newly define a function f in global scope. * See http://bugzilla.mozilla.org/show_bug.cgi?id=185485 * */ //----------------------------------------------------------------------------- var UBound = 0; var bug = 185485; var summary = 'Testing |with (x) {function f() {}}| when |x.f| already exists'; var status = ''; var statusitems = []; var actual = ''; var actualvalues = []; var expect= ''; var expectedvalues = []; var x = { f:0, g:0 }; with (x) { f = 1; } status = inSection(1); actual = x.f; expect = 1; addThis(); with (x) { var f = 2; } status = inSection(2); actual = x.f; expect = 2; addThis(); /* * Use of a function statement under the with-block should not affect * the local property |f|, but define a function |f| in global scope - */ with (x) { function f() {} } status = inSection(3); actual = x.f; expect = 2; addThis(); status = inSection(4); actual = typeof this.f; expect = 'function'; addThis(); /* * Compare use of function expression instead of function statement. * Note it is important that |x.g| already exists.
