Now, Function("print(this)") +* is equivalent to new Function("print(this)") (see 15.3.1.1), and the latter +* ignores the this value that you passed it and constructs a function +* (which we'll call F) which will print the value of the this that will be +* passed in when F will be invoked. +* +* With the last set of () you're invoking F(), which means you're calling it +* with no this value. When you don't provide a this value, it defaults to the +* global object. +* +*/ +//----------------------------------------------------------------------------- +var UBound = 0; +var bug = '(none)'; +var summary = 'Applying Function.prototype.call to the Function object itself'; +var status = ''; +var statusitems = []; +var actual = ''; +var actualvalues = []; +var expect= ''; +var expectedvalues = []; +var self = this; // capture a reference to the global object +var cnOBJECT_GLOBAL = self.toString(); +var cnOBJECT_OBJECT = (new Object).toString(); +var cnHello = 'Hello'; +var cnRed = 'red'; +var objTEST = {color:cnRed}; +var f = new Function(); +var g = new Function(); + + +f = Function.call(self, 'return cnHello'); +g = Function.call(objTEST, 'return cnHello'); + +status = 'Section A of test'; +actual = f(); +expect = cnHello; +captureThis(); + +status = 'Section B of test'; +actual = g(); +expect = cnHello; +captureThis(); + + +f = Function.call(self, 'return this.toString()'); +g = Function.call(objTEST, 'return this.toString()'); + +status = 'Section C of test'; +actual = f(); +expect = cnOBJECT_GLOBAL; +captureThis(); + +status = 'Section D of test'; +actual = g(); +expect = cnOBJECT_GLOBAL; +captureThis(); + + +f = Function.call(self, 'return this.color'); +g = Function.call(objTEST, 'return this.color'); + +status = 'Section E of test'; +actual = f(); +expect = undefined; +captureThis(); + +status = 'Section F of test'; +actual = g(); +expect = undefined; +captureThis(); + + + +//----------------------------------------------------------------------------- +test(); +//----------------------------------------------------------------------------- + + +function captureThis() +{ + statusitems[UBound] = status; + actualvalues[UBound] = actual; + expectedvalues[UBound] = expect; + UBound++; +} + + +function test() +{ + enterFunc ('test'); + printBugNumber (bug); + printStatus (summary); + + for (var i = 0; i < UBound; i++) + { + reportCompare(expectedvalues[i], actualvalues[i], statusitems[i]); + } + + exitFunc ('test'); +} |
