In this tutorial, we will be discussing how to generate a random password using JavaScript. We will create a password generator script that will generate a strong and secure password for users. This project will be great for beginners who are looking to learn how to work with JavaScript and create a useful tool for their projects.
Step 1: Setting Up the HTML File
To start, create a new HTML file and include the following 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">
<title>Password Generator</title>
</head>
<body>
<h1>Password Generator</h1>
<button id="generate">Generate Password</button>
<input type="text" id="password" readonly>
<script src="script.js"></script>
</body>
</html>Step 2: Creating the JavaScript File
Next, create a new JavaScript file called script.js and include the following code:
const generatePassword = () => {
const length = 12;
const charset = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!@#$%^&*()_+{}|:<>?';
let password = '';
for (let i = 0; i < length; i++) {
const randomIndex = Math.floor(Math.random() * charset.length);
password += charset[randomIndex];
}
return password;
};
document.getElementById('generate').addEventListener('click', () => {
document.getElementById('password').value = generatePassword();
});Step 3: Understanding the Script
In the script, we first define a function called generatePassword that will generate a random password. We set the length of the password to 12 characters and define a charset that contains all the characters that can be used in the password.
Next, we loop through the charset and randomly select characters to construct the password. The generated password is then displayed in the input field with the id "password" when the "Generate Password" button is clicked.
Step 4: Testing the Password Generator
Open the HTML file in your browser and click the "Generate Password" button. You should see a random, strong password generated in the input field.
Step 5: Customizing the Password Generator
You can customize the password generator by changing the length and characters used in the charset. For example, you can increase the length of the password or add special characters to make it even more secure.
Additionally, you can add more features to the password generator, such as allowing users to choose the length of the password or selecting specific character sets to include.
Conclusion
In this tutorial, we have created a simple yet effective password generator using JavaScript. This project is a great way to learn more about JavaScript and create a tool that can be used in various web applications. Feel free to experiment with the code and customize the password generator to suit your needs. Happy coding!
… 💚💛❤🙏
Another good tutorial. Thank you.
Thakyou so much brother, because of you i make my first project with these video and gain confidence in coding 😀
Moj 😊
Thank you
Thank you! Second project done successfully
I did everything but I can't have random number , I cotrolled 2 times but who know where is the my mistake copy function worked but random fuction dont ….. (undefined)
💌💌
Which theme is this?
What a delight learning This ❤❤❤
You are good bro, honestly 💢👌👌
My program is successful ❤
function gener() {
const A = "ABCDEFGHIJKLMANOPQRSTUVWXYZ";
const a = "abcdefghijklmnopqrstuvwxyz";
const n = "0123456789";
const s = "!@#$%^&*_-+/<>?|";
const k = A + a + n + s;
let x = k.length;
let r = "";
for (let i = 0; i < 12; i++) r += k[Math.floor(Math.random() * x)];
document.getElementById("p").value = r;
}
Use this function
Completed this quiz app.
Learning ++;
Motivation ++;
Worries –;
Easy for beginners like me ❤
Amazing content buddy, Keep it up 🦾👍
the lines of code from line 32 to 35 are practically useles…
Its amazing it works completely
execCommand is not working in my VS code, it's not allowing me to write it
fourth project!
lets gooooooo
thanks guru 🙂
