How to Go Back to Previous Page in Javascript

By Krishnaa JavaScript Questions 0 Comments

In this tutorial, you will learn how to go back to previous page using javascript. Almost in every browser, we have a back button to navigate back to the previous page.

The functionality of the back button is based on browser history which makes it easy for a user to go and back forth. But sometimes we do want to implement such functionality programmatically and allow a user to go back to the previous page on button click.

To accomplish our goal, we can make use of the History object. This object has various helpful methods and properties to manipulate history of browser session. One of those methods is the back() method which takes a user back to the previously navigated page dynamically. To learn more about History object, please check out MDN docs.

In the following example, we have multiple HTML pages. We will navigate back and forth between those pages using anchor elements and javascript. Please have a look over the code example and the steps given below.

HTML & CSS

We have 3 HTML pages (index, page1, and page2).
The index page contains 2 anchor elements so that we can navigate to page1 and page 2.
Both pages page1 and page2 contain button elements with an innerText of “Go Back”. Upon click of this button, we will take the user back to the index page using javascript.
We have done some basic styling using CSS and added the link to our style.css stylesheet inside the head element.
We have also included our javascript file script.js with a script tag at the bottom of both pages page1 and page 2.

        <h1>Home Page</h1>
        <a href="/page1.html">Page 1</a>
        <a href="/page2.html">Page 2</a>

<body>
    
    <div>
        <h1>Page 2</h1>
        <button>Go Back</button>
    </div>

    <script src="script.js"></script>
</body>
</html>

body {
    text-align: center;
}

Javascript

We have selected the button element using the document.querySelector() method and stored it in the btnBack variable.
We have attached a click event listener to the button element.
In the event handler function, we are calling the back() method to navigate back to the previous page.

let btnBack = document.querySelector('button');

btnBack.addEventListener('click', () => {
    window.history.back();
});
