Document Object Model


The Document Object Model is a platform - and language - neutral interface that will allow programs and scripts to dynamically access and update the content, structure and style of documents. The document can be further processed and the results of that processing can be incorporated back into the presented page. "Dynamic HTML" is a term used by some vendors to describe the combination of HTML, style sheets and scripts that allows documents to be animated. JavaScript is the language used to manipulate document elements. In essence, the DOM makes it possible for programmers to write applications which work properly on all browsers and servers and on all platforms. While programmers may need to use different programming languages, they do not need to change their programming model. The end goal is to have a more fully functional Web Page.

Some of the functionality can be seen in the table.
The table called "The Planets" can be sorted by column.
The sort is accomplished by swapping rows based upon the value of a given column.
The dynamic nature of this page allows information to be better understood.
