Whilst it will be of specific worth to the persons with no programming experience, still persons, who have utilized other programming languages may take advantage of studying about several of the individualities of Javascript.

Introduction to JavaScript

JavaScript is an interpreted, lightweight, object oriented programming language with first class functions, mostly referred to as the scripting language for website pages, but utilized in a number of non browser environments and Apache CoucheDB or node.js. It is a multi paradigm, prototype based scripting language, which is dynamic in nature and supports imperative, functional and object oriented style.

In fact, it has broadly turned into the accepted as a means of explaining what must truly be known as ‘unobtrusive DOM scripting’, essentially the art of inserting JavaScript to the web page in such a manner that if there were no presence of JavaCript, the web page would yet function. You can make use of the DOM scripting with the help of the JavaScript in this highly competitive world by considering the below mentioned code:

__________________________________________________________________________________________

jQuery(function() {
alert(‘The DOM is ready!’);
});

__________________________________________________________________________________________

2.       Chaining method

Chaining method is an ordinary pattern in the world of the JavaScript. Method chaining is a way that can be utilized to simplify the coding in different scenarios that include calling multiple functions on the identical object in  consecutive manner. How to use this method, it is important to realize its coding, mentioned below:

__________________________________________________________________________________________

.css(‘background’, ‘blue’)

.height(100)

.fadeIn(200);

__________________________________________________________________________________________

3.       Handling events

jQuery offers a method .on() in order to respond to any event on the chosen elements. This process is known as event binding. Even though, it is not just the method offered for event binding purposes, in fact, it is the most excellent practice to make use of this for jQuery 1.7+. Different coding for simple event handling and multiple event handling is mentioned below:

Simple event handling:

__________________________________________________________________________________________

// When any <p> tag is clicked, we expect to see ‘<p> was clicked’ in the console.

$( “p” ).on( “click”, function() {

console.log( “<p> was clicked” );

});

Multiple event handling:

// When a user focuses on or changes any input element, we expect a console message

// bind to multiple events

$( “div” ).on( “mouseenter mouseleave”, function() {

console.log( “mouse hovered over or left a div” );

});

4.       DOM Manipulation

jQuery offers methods to manipulate DOM in an easy and effective manner. There is no need to write large code for modifying the value of any attribute of the element or for removing HTML coding from a division or a paragraph. In fact, the jQuery offers methods like .html(), attr() and .val() that serve as getters, getting back information from the elements of the DOM for utilization purposes in the future.

__________________________________________________________________________________________

// Changing the HTML of an element.

$( “#myDiv p:first” ).html( “New <strong>first</strong> paragraph!

OR

var div = jQuery(‘<div>Some text</div>’).addClass(‘inserted’).attr(‘id’, ‘foo’);

__________________________________________________________________________________________

5.       Change()

With this method, you can bind an event handler for changing the JavaScript event or triggering that event on a particular element. This method serves as a shortcut for .on(‘’change’’, handler) available in the first two variations and also .trigger(‘’change”) in the next or you can say the third one.

__________________________________________________________________________________________

$( “.target” ).change(function() {

alert( “Handler for .change() called.” );

});

Without arguments, you can use this code:

$( “#other” ).click(function() {

$( “.target” ).change();

});
