What is DOM ?

The 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 events for all HTML elements
- The methods to access all HTML elements



<title>Simple HTML</title>
<script type="javascript">

function LoadMeFirst(){
alert("Html Dom loading.....");
function ClickME(){
alert("Dom Loaded and hence the button is clicked");
var accessingTheParagraphText = document.getElementsByTagName('p')[0].innerHTML;

<body onLoad="LoadMeFirst()">
<p>A simple paragraph</p>
<input type="button" id="myButton" value="MyButton" onClick="ClickME()" />

In the above code snippet example,

- The button properties are - TYPE,ID,VALUE
- The Event for

a) BODY is: onLoad
b) BUTTON is: onClick

- Method to access the HTML elements - getElementsByTagName

What is DOM selector in jquery (AKA JQuery Selector) ?

An excerpt from my article ( http://www.dotnetfunda.com/articles/show/1918/let-us-learn-jquery-part-2-of-9jquery-selectors )

jQuery selector($),the vital part of JQuery, allow Html elements to be selected and manipulated (Check out the 4th point of DOM answer provided above ) .It finds the elements by Element Name,Element ID or class and returns a sequence of matched DOM elements upon a successful match. We can they apply methods or logics on those collection for further processing.


$(Selector Expression)
