Redirecting with JavaScript

Using JavaScript for redirection provides a dynamic and efficient way to control user navigation. Below, we’ll explore various scenarios and code snippets for redirecting with JavaScript.

Usage

Simple Redirect

The most straightforward way to redirect users is by utilizing the window.location object. This method changes the current URL to the specified one.

JavaScript
// Redirect to a specific URL
window.location.href = 'https://example.com';

Delayed Redirect

If you want to introduce a delay before redirecting, you can use setTimeout in conjunction with window.location.

JavaScript
// Redirect after 3 seconds
setTimeout(function() {
    window.location.href = 'https://example.com';
}, 3000);

Conditional Redirect

Redirect users based on a certain condition, such as the value of a variable or the result of a function.

JavaScript
// Redirect only if the user is logged in
if (isLoggedIn) {
    window.location.href = 'https://secure-site.com';
} else {
    window.location.href = 'https://public-site.com';
}
