DHTML-Introduction

Written by Eddie Traversa


Think of DHTML as not a singular technology but a combination of three existing technologies glued together byrepparttar Document Object Model (DOM):

1. HTML - For creating text and image links and other page elements.

2. CSS - Style Sheets for further formatting of text and html plus other added features such as positioning and layering content.

3. JavaScript - The programming language that allows you to accesses and dynamically controlrepparttar 105179 individual properties of both HTML and Style Sheets.

The way JavaScript accessesrepparttar 105180 properties of an HTML document is throughrepparttar 105181 Document Object Model (DOM). The job ofrepparttar 105182 DOM is to expose allrepparttar 105183 attributes of HTML and Style sheets to JavaScript control. All you need to know aboutrepparttar 105184 DOM is what JavaScript commands it accepts. Not that easy, as different browsers have their slightly different versions ofrepparttar 105185 DOM, so they access HTML properties differently as well as display them differently.

So how do you locate an HTML element on a page and change its property? This isrepparttar 105186 job of JavaScript. Obviously, I cant into allrepparttar 105187 details of JavaScript orrepparttar 105188 DOM, but here is an example of how JavaScript can change a visibility of a style sheet layer in both browsers.

Note: That every piece of HTML has a location much like a directory in a phone book. When finding that piece of HTML you have to go throughrepparttar 105189 same hierarchy process of searching for a name inrepparttar 105190 phone book such as

(state) Washington -> (City) Seattle -> (Listings) j -> (Name) Jessica

In JavaScript, a reference to this would be equivalent to

washington.seattle.j.jessica

Now Jessica may have additional information such as her address and phone number, sorepparttar 105191 JavaScript reference would be written this way.

washington.seattle.j.jessica.address

or

washington.seattle.j.jessica.phone
