Question 1: Creating a Responsive Navigation Menu
You've been tasked with designing a responsive navigation menu for a website that adapts seamlessly to various screen sizes, ensuring optimal user experience across devices. How would you approach this challenge, considering both desktop and mobile layouts? Provide a detailed explanation along with a code snippet illustrating your solution.
Solution:
To create a responsive navigation menu, we'll leverage CSS media queries to adjust the layout based on the screen size. First, let's define the HTML structure for our navigation menu:
```html
nav class="navigation"
ul
lia href="#"Home/a/li
lia href="#"About/a/li
lia href="#"Services/a/li
lia href="#"Contact/a/li
/ul
/nav
```
Next, we'll style the navigation menu using CSS:
```css
.navigation {
background-color: #333;
}
.navigation ul {
list-style: none;
padding: 0;
margin: 0;
}
.navigation li {
display: inline-block;
margin-right: 20px;
}
.navigation a {
color: #fff;
text-decoration: none;
padding: 10px;
}
@media screen and (max-width: 768px) {
.navigation li {
display: block;
margin: 0;
}
}
```
In the above code, we've created a horizontal navigation menu for desktop screens. However, when the screen size falls below 768 pixels (typically representing smaller devices such as tablets and mobile phones), the navigation menu switches to a vertical layout, ensuring easy navigation on smaller screens.
Question 2: Implementing Form Validation with JavaScript
You're building a registration form for a website and need to implement client-side form validation using JavaScript. The form should validate user input for required fields, email format, and password strength. How would you approach implementing this form validation, ensuring a smooth and error-free user experience?
Solution:
To implement form validation with JavaScript, we'll start by defining our HTML registration form:
```html
form id="registrationForm" action="#" method="post"
input type="text" id="username" name="username" placeholder="Username" required
input type="email" id="email" name="email" placeholder="Email" required
input type="password" id="password" name="password" placeholder="Password" required
button type="submit"Register/button
/form
```
Next, we'll write the JavaScript code to validate the form:
```javascript
document.getElementById("registrationForm").addEventListener("submit", function(event) {
var username = document.getElementById("username").value;
var email = document.getElementById("email").value;
var password = document.getElementById("password").value;
// Validate username
if (username.length 3) {
alert("Username must be at least 3 characters long.");
event.preventDefault();
return false;
}
// Validate email format
var emailRegex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/;
if (!emailRegex.test(email)) {
alert("Please enter a valid email address.");
event.preventDefault();
return false;
}
// Validate password strength
if (password.length 8) {
alert("Password must be at least 8 characters long.");
event.preventDefault();
return false;
}
// Password must contain at least one uppercase letter, one lowercase letter, one number, and one special character
var passwordRegex = /^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[!@#$%^*()_+])[A-Za-z\d!@#$%^*()_+]{8,}$/;
if (!passwordRegex.test(password)) {
alert("Password must contain at least one uppercase letter, one lowercase letter, one number, and one special character.");
event.preventDefault();
return false;
}
// Form validation successful
alert("Registration successful!");
return true;
});
```
In the above JavaScript code, we've added an event listener to the registration form's submit event. When the form is submitted, the script retrieves the values of the username, email, and password fields and validates them against predefined criteria. If any validation checks fail, an alert message is displayed, and the form submission is prevented. Otherwise, a success message is shown, indicating that the registration was successful.
