Ok, we are ready to see how to access forms-manipulate them, validate them, etc. Before we start diving in head first, lets just take a even closer look at the object concept of JavaScript, which will all tie in with accessing forms. Whether are not you know it, almost everything on your page is an instance of a object. Since they are objects, like the window object, they can be accessed and played around with. Now that we know a little more about objects, lets talk about what objects really are, and where things stand in terms of all the objects in JavaScript.
Lets use a typical example.
In real life, a car would be the object, the leather seats, power steering would be the properties, and the car's ability to move around is the object's method. In JavaScript, its just like that, however, properties of one object may itself be another object, which in turn contains other properties. This is important, and I will talk a little more about this. This is to access and point to what you want when using JavaScript. Ok, now we want JavaScript to alert us the value inside this box.
