Html ,What is use of DOM ?

Hi,

 

Use will get easily answer of your question after reading these lines.

 

The DOM (Document Object Model) is an interface that represents how your HTML and XML documents are read by the browser. It allows a language (JavaScript) to manipulate, structure, and style your website. After the browser reads your HTML document, it creates a representational tree called the Document Object Model and defines how that tree can be accessed.

This is the description of DOM:

 

The DOM is a W3C (World Wide Web Consortium) standard. The DOM defines a standard for accessing documents:

 

"The W3C Document Object Model (DOM) is a platform and language-neutral interface that allows programs and scripts to dynamically access and update the content, structure, and style of a document."

 

The W3C DOM standard is separated into 3 different parts:Core DOM - standard model for all document typesXML DOM - standard model for XML documentsHTML DOM - standard model for HTML documentsThe HTML DOM is a standard object model and programming interface for HTML. It defines:The HTML elements as objects.The properties of all HTML elements. The methods to access all HTML elements. The events for all HTML elements.

Hi,

 

DOM is document object Model. It defines structure of document. Lets take example we have one table in our page than How it will work.

 

Hello 

 

Dom-The Document Object Model (DOM) is a programming API for HTML and XML documents. It defines the logical structure of documents and the way a document is accessed and manipulated. In the DOM specification, the term "document" is used in the broad sense - increasingly, XML is being used as a way of representing many different kinds of information that may be stored in diverse systems, and much of this would traditionally be seen as data rather than as documents. Nevertheless, XML presents this data as documents, and the DOM may be used to manage this data. 

 

With the Document Object Model, programmers can create and build documents, navigate their structure, and add, modify, or delete elements and content. Anything found in an HTML or XML document can be accessed, changed, deleted, or added using the Document Object Model, with a few exceptions - in particular, the DOM interfaces for the internal subset and external subset have not yet been specified.
