Document Object Model and Dynamic HTML
The term Dynamic HTML,often abbreviated DHTML,refers to the technique of making Web pages dynamic by client—side scripting to manipulate the document content and pages can be made more lively,dynamic,or interactive by DHTML techniques.
With DHTML,you can prescribe actions triggered by browser events to make the page more lively and responsive。Such actions may alter the content and appearance of any parts of the page。The changes are fast and efficient because they are made by the browser without having to network with any servers。Typically,the client-side scripting is written in JavaScript and basic techniques for making Web pages dynamic.
Contrary to what the name may suggest,DHTML is not a markup language or a software is a technique to make Web pages dynamic through client-side programming。In the past,DHTML relied on browser—and vendor—specific features。Making such pages work for all browsers requires much effort,testing,and unnecessarily long programs.
Standardization efforts at W3C and elsewhere are making it possible to write standard—based DHTML that works for all compliant -based DHTML involves three aspects.
1。JavaScript—for cross-browser scripting(Chapter9)
Style Sheets(CSS)-for style and presentation control (Chapter6)
3.Document Object Model(DOM)-for a uniform programming interface to access and manipulate the Web page as a document
When these three aspects are combined,you get the ability to program changes in Web pages in reaction to user-or browser—generated events。Therefore,you can make HTML pages more dynamic.
