jQuery Effect Methods Example

Greetings readers, in this tutorial, we will show how to use the jQuery library and the different jQuery effect methods to perform an animation or effect to the selected HTML element on a web-page.

1. Introduction

jQuery is nothing but a JavaScript library that comes with rich functionalities. It is small and faster than many JavaScript code written by an average web developer. By using jQuery developers can write less code and do more things, making web developer’s tasks very easy. In simple word, jQuery is a collection of several useful methods, which can be used to carry out many common tasks in JavaScript. A couple of lines of jQuery code can do things which need too many JavaScript lines to do. The true power of jQuery comes from its CSS-like selector, which allows it to select any element from DOM and change, update or manipulate it. Developers can use jQuery to do cool animations like fade in or fade out. They can also change the CSS class of a component dynamically e.g. making a component active or inactive. I have used this technique to make tabbed UI in HTML. I can vouch for jQuery that once developers start using it, they will never go back to plain old JavaScript as jQuery is clear, concise, and powerful.

1.1 Why jQuery?

  • It helps in improving the application performance and increasing the developer’s productivity
  • It helps in developing the browser compatible web-page
  • It helps in implementing the UI related critical functionality without writing the several lines of codes
  • It is fast and extensible i.e. developers can use the jQuery library to implement the customized behavior
  • It is simpler and easy to learn

1.2 jQuery Effect Methods

The jQuery library provides several methods for adding the animation or effects to the selected HTML element on the web page. Developers can apply these jQuery effects to the selected HTML elements. The following table lists the common jQuery effects.

jQuery MethodDescription
hide()Hide the selected HTML element
show()Display the selected HTML elements
toggle()Display or hide the selected HTML elements
fadeIn()Perform the fade-in effect on the selected HTML elements
fadeOut()Perform the fade-out effect on the selected HTML elements
fadeTo()Perform the fade-out effect on the selected HTML elements to a given opacity
fadeToggle()Perform the fade-in or fade-out effect on the selected HTML elements.
slideDown()Perform the sliding-down motion effect to display the selected HTML elements
slideUp()Perform the sliding-up motion effect to hide the selected HTML elements
slideToggle()Perform the sliding-up or sliding-down motion effect to hide or show the selected HTML elements
animate()Perform the custom animation using the element’s CSS properties
delay()Using the timer set, it delays the execution of the items in the queue
stop()Stop the current animation which is running on the selected HTML elements

1.3 Commonly Used jQuery Effect Methods

These new APIs make a developer life easier, really! But it would be difficult for a beginner to understand this without an example. Therefore, let us create a simple application using the jQuery library.

2. jQuery Effect Methods Example

Here is a systematic guide for implementing this tutorial using the jQuery library.

2.1 Tools Used

We are using Eclipse Kepler SR2, JDK 8 and Maven. Having said that, we have tested the code against JDK 1.7 and it works well.

2.2 Project Structure

Firstly, let us review the final project structure if you are confused about where you should create the corresponding files or folder later!

jQuery Effect Methods - Application Project Structure

Fig. 1: Application Project Structure

2.3 Project Creation

This section will show on how to create a Java-based Maven project with Eclipse. In Eclipse Ide, go to File -> New -> Maven Project.

jQuery Effect Methods - Create a Maven Project

Fig. 2: Create a Maven Project

In the New Maven Project window, it will ask you to select the project location. By default, ‘Use default workspace location’ will be selected. Just click on the next button to proceed.

jQuery Effect Methods - Project Details

Fig. 3: Project Details

Select the ‘Maven Web App’ Archetype from the list of options and click next.

jQuery Effect Methods - Archetype Selection

Fig. 4: Archetype Selection

It will ask you to ‘Enter the group and the artifact id for the project’. We will input the details as shown in the below image. The version number will be by default: 0.0.1-SNAPSHOT.

jQuery Effect Methods - Archetype Parameters

Fig. 5: Archetype Parameters

Click on Finish and the creation of a maven project is completed. If you see, it has downloaded the maven dependencies and a pom.xml file will be created. It will have the following code:

pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
	<modelVersion>4.0.0</modelVersion>
	<groupId>com.jquery</groupId>
	<artifactId>jQueryEffectMethods</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<packaging>war</packaging>
</project>

3. Application Building

Let us create an application to understand the basic building blocks of this tutorial.

3.1 Load the jQuery Library

Since it is a pure JavaScript framework, so developers should add its reference using the <script> tag.

<script type="text/javascript" src="resource/js/jquery-3.3.1.min.js"></script>

Developers can either download the jQuery from the official website and the application will then directly load the jQuery library from the local drive or they can also include the direct CDN link under the script tag.

3.2 Define the Application

3.2.1 Index Page

Let us write a simple index page in the jQueryEffectMethods/src/main/webapp/ folder. Add the following code to it:

index.jsp

4. Run the Application

As we are ready for all the changes, let us compile the project and deploy the application on the Tomcat7 server. To deploy the application on Tomat7, right-click on the project and navigate to Run as -> Run on Server.

Fig. 6: How to Deploy Application on Tomcat

Tomcat will deploy the application in its web-apps folder and shall start its execution to deploy the project so that we can go ahead and test it in the browser.

5. Project Demo

Open your favorite browser and hit the following URL to display the application’s index page as shown in Fig. 7.

http://localhost:8082/jQueryEffectMethods/

Server name (localhost) and port (8082) may vary as per your Tomcat configuration.
