Hello =) I have an object which contains a method that should execute every x ms. I can use setInterval inside the object construct like this - self.setInterval('ObjectName.methodName()', this.pinginterval); - but is there no way to do this without using the literal ObjectName? If I write 'this.methodName()' I get "Line 1 Char 1: Object doesn't support this property or method." in IE, and nothing happens in Firebird.

I'd like to be able to get the name of an object instance from within a call to a method of that same object. Is this at all possible? The example below works by passing in the name of the object instance (in this case 'myDog'). Of course it would be better if I could somehow know from within write() that the name of the object instance was 'myDog' without having to pass it as a parameter. //////////////////////////////// function...

Here are some questions that i am interested about and wanted to here an explanation/discussion: 1. (general) Is the objectness in JavaScript was supported from the very first version of it (in browsers) ? What about the new syntax of creating a object using { 'propName1':'propValue1', 'propName2':'propValue2', 'propName3':{ /* another object */ } } - from what version of JScript/JavaScript it was supported (from what browsers versions) ?...

Hi all, I've got a little hole in my head concerning references. Here's what I'm trying to do: I'm calling a function, passing the reference of a business object for editing. The function clones the object, calls an editor dialog to let the user edit the object, and then - depending on the DialogResult - assigns either the clone/backup copy or the modified object itself to the reference. Maybe I'm thinking too much in pointer references...

A global variable is really just a property of the "Global Object", so what does that make a function defined in the global context? A method of the Global Object? http://developer.mozilla.org/en/docs/Core_JavaScript_1.5_Guide:Defining_Functions doesn't actually give any insight.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
