How to Redirect to Another Webpage in JavaScript

By the end of this page, you will understand how browser redirects work in JavaScript, how to send a user to a new URL, when to use window.location.href versus window.location.replace(), and why jQuery is usually not needed for redirects.

Redirecting means telling the browser to load a different URL.

In web development, this is commonly done after an action such as:

• submitting a form
• logging in successfully
• logging out
• clicking a button
• checking whether a user has permission to view a page

In JavaScript, redirects are usually handled through the browser's window.location object. This object represents the current page URL and gives you ways to change it.

The most common redirect approaches are:

• window.location.href = "https://example.com" — sends the user to a new page
• window.location.assign("https://example.com") — also sends the user to a new page
• window.location.replace("https://example.com") — sends the user to a new page without keeping the current page in browser history

This matters because browser history affects the Back button:

• with href or assign(), the user can usually click Back to return
• with replace(), the current page is replaced, so Back usually will not return to it

Although the question mentions jQuery, jQuery does not provide a special redirect feature. In practice, developers use normal JavaScript even inside jQuery event handlers.

Example:

$("#goButton").on("click", function () {
  window.location.href = "/dashboard";
});

So the core concept is not really a jQuery feature. It is a browser navigation feature provided by JavaScript.

Think of window.location as the browser's address bar.

• Reading it is like looking at the current address.
• Changing it is like typing a new address and pressing Enter.
• Using replace() is like swapping the current history entry instead of adding a new one.

So if you write:

window.location.href = "/home";

you are effectively telling the browser: "Go to this address now."

Basic redirect syntax

window.location.href = "https://example.com";

This loads the new page and keeps the current page in browser history.

Using assign()

window.location.assign("https://example.com");

This behaves similarly to href.

Using replace()

window.location.replace("https://example.com");

This redirects without leaving the current page in the browser history.

Redirect to another page on the same site

window.location.href = "/profile";

This is common for internal navigation.

Redirect after a button click

Consider this example:

const isLoggedIn = true;

if (isLoggedIn) {
  window.location.href = "/dashboard";
}

Step by step:

1. isLoggedIn is created and set to true.
2. The if statement checks whether isLoggedIn is truthy.
3. Because the value is true, the code inside the block runs.
4. window.location.href is assigned the value "/dashboard".
5. The browser starts navigating to /dashboard.
6. The current page stops being the active page once navigation completes.

Now compare this version:

const isLoggedIn = true;

if (isLoggedIn) {
  window.location.replace("/dashboard");
}

The early steps are the same, but the history behavior changes:

Redirects are used in many practical situations:

• Login flow: after successful authentication, send the user to /dashboard
• Logout flow: after clearing session data, send the user to /login
• Protected pages: if a user is not authorized, redirect to /unauthorized or /login
• Form submission: after saving data, redirect to a confirmation page
• Moved content: send users from an old route to a new route
• Language or region handling: redirect users to /en, /fr, or region-specific pages
• Checkout flow: move users to payment, confirmation, or order summary pages

Example of redirecting unauthenticated users:

if (!userIsAuthenticated) {
  window.location.replace("/login");
}

This is common because you may not want users to go Back to a protected page.

In real projects, redirects are often combined with application logic rather than written by themselves.

Guard clauses

A common pattern is checking a condition early and redirecting immediately.

if (!token) {
  window.location.replace("/login");
  return;
}

This avoids deeply nested code.

After validation or success

if (formIsValid) {
  saveData();
  window.location.href = "/success";
}

Error handling flows

if (response.status === 401) {
  window.location.replace("/login");
}

Redirect after async work

fetch("/api/logout", { method: "POST" })
  .then( {
    .. = ;
  });

1. Thinking jQuery has a special redirect method

jQuery does not have a built-in redirect API.

// Not a real jQuery redirect method
$.redirect("/home");

Use standard JavaScript instead:

window.location.href = "/home";

2. Forgetting the difference between href and replace()

If you want the user to be able to go back, use href or assign(). If you do not want that, use replace().

window.location.replace("/login");

3. Using an invalid or incomplete URL accidentally

Broken:

window.location.href = "example.com";

jQuery vs plain JavaScript

// Standard redirect
window.location.href = "/home";

// Equivalent redirect method
window.location.assign("/home");

// Redirect without keeping current page in history
window.location.replace("/home");

// Delayed redirect
setTimeout(() => {
  window.location.href = "/home";
}, 1000);

Quick rules

• Use window.location.href for most redirects.
• Use window.location.replace() when the user should not return to the previous page with Back.
• jQuery is not needed for redirecting.
• Use relative URLs like /dashboard for internal pages.
• Use full URLs like https://example.com for external sites.
• Be careful with redirect loops.
• Prefer server-side redirects when the page should always redirect.

Useful reminder

window.location represents the current browser URL. Changing it tells the browser to navigate somewhere else.

How do I redirect to another page in JavaScript?

Use:

window.location.href = "/new-page";

How do I redirect without allowing the user to go back?

Use:

window.location.replace("/new-page");

Is there a jQuery function for redirects?

No. jQuery does not provide a special redirect method. Use window.location.

What is the difference between href and replace()?

href keeps the current page in browser history. replace() removes it from history.

Can I redirect after a delay?

Yes:

setTimeout(() => {
  window.location.href = "/next";
}, 2000);

• window.location — the browser API used to read or change the current URL
• event handling — redirects often happen after clicks, submits, or async results
• form submission — many redirects happen after successful form processing
• conditional statements — redirects are often triggered inside if checks
• browser history — important for understanding href versus replace()
• client-side routing — modern apps may use routers instead of full page reloads
• server-side redirects — useful when navigation should happen before the page loads
