JavaScript's interaction with HTML is handled through events that occur when the user or the browser manipulates a page. When the page loads, it is called an event. When the user clicks a button, that click too is an event. Other examples include events like pressing any key, closing a window, resizing a window, etc. Developers can use these events to execute JavaScript coded responses, which cause buttons to close windows, messages to be displayed to users, data to be validated, and virtually any other type of response imaginable. Events are a part of the Document Object Model (DOM) Level 3 and every HTML element contains a set of events which can trigger JavaScript Code. Here we will see a few examples to understand a relation between Event and JavaScript In JavaScript many types of events, onchange, onclick, onmouseover, onmouseout, onkeydown, onload, onblur, ondrop, onfocus, etc. **Onclick event** This is most frequently used event type which occur when a user click the button of his mouse. **Somejs.js**

var name = window.document.getElementById('color');
alert('Your selected color is : ' + name.value);
name.style.backgroundColor = name.value;
window.document.body.style.backgroundColor = name.value;
}
```
**Some.html**

When a web page is loaded, the browser creates a Document object model of the page. • JavaScript can change all the HTML elements in the page • JavaScript can change all the HTML attributes in the page • JavaScript can change all the CSS styles in the page • JavaScript can remove existing HTML elements and attributes • JavaScript can add new HTML elements and attributes • JavaScript can react to all existing HTML events in the page • JavaScript can create new HTML events in the page The HTML DOM is a standard object model and programming interface for HTML in DOM. • The HTML elements as objects • The properties of all HTML elements • The methods to access all HTML elements • The events for all HTML elements The HTML DOM is a standard for how to get, change, add, or delete HTML elements. **Finding HTML elements** document.getElemntById(id) document.getElemntsByClassName(class-name) document.getElemntsByTagName(tagname) **Changing HTML element** element.innerHTML element.attribute element.style.property **Adding events handler** document.getElementById(id).event-name= function-name(){ Function body } \

The Document Object Model is a standard of the W3C (World Wide Web). It defines the standard for accessing a document. In other words, the Document Object Model provides a platform for programs and scripts to dynamically access and update the structure, style, and content of a document.
