Introduction of the Project
In this JavaScript project, we will explore how to build a simple Lorem Ipsum generator using JavaScript. We will start with a brief explanation of Lorem Ipsum and its purpose, followed by a breakdown of the steps involved in building the generator.
Lorem ipsum text is commonly used as a placeholder in design projects or as a temporary filler for content. Manually copying and pasting the same standard dummy text can be tedious, which is why a Lorem Ipsum generator can be useful for quickly generating a block of placeholder text.
We will be using JavaScript to create the generator, which will be designed to allow the user to select the number of paragraphs they require and the length of each paragraph. By the end of the tutorial, you will have a fully functional Lorem Ipsum generator that you can customize and use in your own web development projects.
To build this generator, you will need to have a basic understanding of JavaScript, HTML, and CSS. However, we will explain each step in detail, so even if you are new to these programming languages, you should be able to follow along.
To make this project’s user interface more interesting, we will be implementing some GUI using HTML and CSS and a method that produces a specified number of random words.
So, let’s get started and build our own Lorem Ipsum generator using JavaScript!
Objectives
1. Understand the purpose of Lorem Ipsum and why it is used as placeholder text.
2. Design a user interface that allows the user to input the number of words.
3. Use JavaScript to choose specified number of random words stored in the array & display it in the text area based on the user’s input.
4. Learn how to store the generated text in an HTML element, such as a <div> tag.
5. Implement error handling to ensure that the user’s input is valid and prevent the generator from crashing.
6. Improve the generator’s functionality by adding features such as the ability to copy the generated text to the clipboard. Also, improve the design by incorporating additional features, such as the ability to customize the font, color, or formatting of the generated text.
7. Optimize the generator’s performance to ensure that it can handle large amounts of text without slowing down the page.
8. Test the generator thoroughly to identify and fix any bugs or issues.
9. Publish the generator and share it with the web development community.
Requirements
To build a Lorem Ipsum generator using JavaScript, you will need to have a basic understanding of the following technologies:
HTML: You should know how to create basic HTML markup, including elements such as <div>, <form>, <input>, and <button>.
CSS: You should know how to add basic styles to HTML elements using CSS, such as changing the font family, font size, and colors.
JavaScript: You should have a good understanding of core JavaScript concepts, such as variables, functions, loops, and conditionals.
Visual Studio Code or any other code editor installed on your computer, such as Atom or Sublime Text.
Familiarity with working with HTML tags and attributes, including the ability to create form elements and manipulate the DOM.
Proficiency in using JavaScript to manipulate HTML elements and handle user input, including event handling and creating functions.
Source Code
HTML Code
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <link rel="stylesheet" href="ipsum.css"> <title>Word Counter</title> </head> <body> <h1>Lorem Ipsum</h1><br> <div id="container" style="text-align: center;"> <label for="">ENTER NUMBER OF WORDS TO GENERATE:</label> <input type="text" id="number"><br> <button onclick="generate()" style="margin-top:20px;font-size:large;font-weight: bold;">GENERATE WORDS</button><br> <textarea name="" id="textA" cols="30" rows="10"></textarea> </div> <script src="main.js"></script> </body> </html>
CSS Code
#textA{
width: 800px;;
height: 50vh;
margin-top: 50px;
}
h1{
text-align: center;
}
button{
font-family: 'Courier New', Courier, monospace;
color: crimson;
}
#asd{
margin-top: 100px;
margin-left:50%;
font-size: large;
font-weight: bold;
}JAVASCRIPT Code
function generate(){
var str = "Lorem ipsum dolor sit amet consectetur adipiscing elit Nunc eros nulla condimentum nec bibendum eget feugiat congue ante Cras dolor";
var strArray = str.split(" ");
var finalStr="";
for(i=0;i<document.getElementById('number').value;i++){
var x =Math.floor(Math.random()*20);
finalStr=finalStr+strArray[x]+" ";
}
document.getElementById('textA').value = finalStr;
}Explanation of the Code
We have broken down the source code into three sections. The first two parts are HTML & CSS, that involves creating the GUI and styling it.
1. The code consists of an input tag, a button and a text area. The user can input the number of words in the input area based on which the text area will display the paragraph
2. The CSS code has managed the height and margin of the elements in the container. We have set the font-family of the entire page to Courier New font, and set the background color to crimson.
Moving to the JavaScript code, we have production of random words.
1. We have created a method that uses some amount of lorem ipsum words that will be chosen randomly.
2. We have used a random method of Math class to choose random indexes to access random words from array.
3. Finally, a string is built from the words & sent to the text area.

Points To Remember
We have successfully built Lorem Ipsum Generator using JavaScript. This is a helpful website which can be used by developers where they require dummy text to make appropriate changes to user interface. Here are some key points to keep in mind when building a Lorem Ipsum Generator using JavaScript:
- Set up a basic HTML structure that includes a textarea to display the generated text and a button to trigger the text generation.
- Use CSS to style the HTML elements to create a visually appealing user interface.
- Write JavaScript code to generate the Lorem Ipsum text. You can either use a pre-built library or write your own algorithm to generate random text.
- Use event listeners to detect when the user clicks the button and trigger the text generation function.
- Display the generated text in the textarea element for the user to view.
- Add additional features to customize the generated text, such as the number of paragraphs or words or the type of text (such as Latin or English).
- Test your generator thoroughly to ensure it works as expected and that the generated text is accurate and appropriate.
- Consider making your code reusable by turning it into a JavaScript module or function that can be easily integrated into other projects.
- Ensure that your generator is accessible and follows best practices for web development, such as using semantic HTML and providing alternative text for non-text elements.
- Continuously update and improve your generator as needed based on user feedback and changes in web development standards and technologies.
