Note:This article uses a DOM-compatible browser such as Netscape 6.x, Internet Explorer 6, or Mozilla 1.0.
In the last few years the object structure of internet browsers has become standardised, making programming easier. Prior to this, browsers from different manufacturers had different object structures. Unfortunately, many such browsers are still in use. The objects are arranged into a hierarchy as shown below: The Document Object Model.
Working with JavaScript Objects. Before you can write an object variable, you should understand the premise of an object.
