Refresh the Page in JavaScript – JS Reload Window Tutorial
Joel Olawanle
When you’re developing applications like a blog or a page where the data may change based on user actions, you’ll want that page to refresh frequently.
When the page refreshes or reloads, it will show any new data based off those user interactions. Good news – you can implement this type of functionality in JavaScript with a single line of code.
In this article, we will learn how to reload a webpage in JavaScript, as well as see some other situations where we might want to implement these reloads and how to do so.
Here’s an Interactive Scrim about How to Refesh the Page in JavaScript
How to Refresh a Page in JavaScript With location.reload()
You can use the location.reload() JavaScript method to reload the current URL. This method functions similarly to the browser’s Refresh button.
The reload() method is the main method responsible for page reloading. On the other hand, location is an interface that represents the actual location (URL) of the object it is linked to – in this case the URL of the page we want to reload. It can be accessed via either document.location or window.location .
The following is the syntax for reloading a page:
Note: When you read through some resources on “page reload in JavaScript”, you’ll come across various explanations stating that the relaod method takes in boolean values as parameters and that the location.reload(true) helps force-reload so as to bypass its cache. But this isn’t the case.
According to the MDN Documentation, a boolean parameter is not part of the current specification for location.reload() — and in fact has never been part of any specification for location.reload() ever published.
Browsers such as Firefox, on the other hand, support the use of a non-standard boolean parameter known as forceGet for location.reload() , which instructs Firefox to bypass its cache and force-reload the current document.
Aside from Firefox, any parameters you specify in a location.reload() call in other browsers will be ignored and have no effect.
How to Perform Page Reload/Refresh in JavaScript When a Button is Clicked
So far we have seen how reload works in JavaScript. Now let’s now see how you can implement this could when an event occurs or when an action like a button click occurs:
Note: This works similarly to when we use document.location.reload() .
How to Refresh/Reload a Page Automatically in JavaScript
We can also allow a page refersh after a fixed time use the setTimeOut() method as seen below:
Using the code above our web page will reload every 3 seconds.
So far, we’ve seen how to use the reload method in our HTML file when we attach it to specific events, as well as in our JavaScript file.
How to Refresh/Reload a Page Using the History Function in JavaScript
The History function is another method for refreshing a page. The history function is used as usual to navigate back or forward by passing in either a positive or negative value.
For example, if we want to go back in time, we will use:
This will load the page and take us to the previous page we navigated to. But if we only want to refresh the current page, we can do so by not passing any parameters or by passing 0 (a neutral value):
Note: This also works the same way as we added the reload() method to the setTimeOut() method and the click event in HTML.
Wrapping Up
In this article, we learned how to refresh a page using JavaScript. We also clarified a common misconception that leads to people passing boolean parameters into the reload() method.

JavaScript Refresh Page – How to Reload a Page in JS
Joel Olawanle
JavaScript is a versatile programming language that allows developers to create dynamic and interactive web applications. One common task in web development is to refresh or reload a web page, either to update its content or to trigger certain actions.
In this article, we will explore different ways to refresh a page in JavaScript and understand the pros and cons of each approach.
Why Refresh a Page in JavaScript?
Refreshing a web page can be useful in various scenarios. For example:
- Content Update: If the content on a web page is dynamic and changes frequently, you may need to refresh the page to display the latest data or information. This is commonly seen in news websites, stock market trackers, weather apps, and so on.
- Form Submission: After submitting a form on a web page, you may want to refresh the page to show a success message or reset the form for a new submission.
- State Reset: In some cases, you may want to reset the state of a web page or clear certain data to start fresh. Refreshing the page can help achieve this.
Now, let’s explore different ways to refresh a page in JavaScript.
Method 1: How to Refresh the Page Using location.reload()
The simplest way to refresh a page in JavaScript is to use the location.reload() method. This method reloads the current web page from the server, discarding the current content and loading the latest content.
// Refresh the page location.reload();
Pros of Using location.reload()
- It’s straightforward and easy to use.
- It reloads the entire page from the server, ensuring that you get the latest content.
Cons of Using location.reload()
- It discards the current content of the page, which can result in loss of user input or data.
- It may cause a flickering effect as the page reloads, which can impact user experience.
Method 2: How to Refresh the Page Using location.replace()
Another way to refresh a page in JavaScript is to use the location.replace() method. This method replaces the current URL of the web page with a new URL, effectively reloading the page with the new content.
When you try this in your console, you will notice it displays your current URL:
This means, when you use the location.replace() method to replace the current URL of the web page with a new URL (same URL), your page will refresh.
// Refresh the page by replacing the URL with itself location.replace(location.href);
Pros of Using location.replace()
- It’s a quick way to reload the page with new content.
- It preserves the current content of the page and replaces only the URL, avoiding loss of user input or data.
Cons of Using location.replace()
- It replaces the entire URL of the page, which may result in the loss of the current browsing history.
- It may not work in some scenarios, such as when the web page was opened in a new window or tab.
Method 3: How to Refresh the Page Using location.reload(true)
The location.reload() method also accepts a boolean parameter forceGet which, when set to true , forces the web page to reload from the server, bypassing the cache.
This can be useful when you want to ensure that you get the latest content from the server, even if the page is cached.
// Refresh the page and bypass the cache location.reload(true);
Pros of Using location.reload(true)
Cons of Using location.reload(true)
- It discards the current content of the page, which can result in loss of user input or data.
- It may cause a flickering effect as the page reloads, which can impact user experience.
Method 4: How to Refresh the Page Using location.href
Another way to refresh a page in JavaScript is to use the location.href property to set the URL of the web page to itself. This effectively reloads the page with the new URL, triggering a page refresh.
// Refresh the page by setting the URL to itself location.href = location.href;
Pros of Using location.href
- It’s a simple and effective way to refresh the page.
- It preserves the current content of the page and only updates the URL, avoiding loss of user input or data.
Cons of Using location.href
- It replaces the entire URL of the page, which may result in the loss of the current browsing history.
- It may not work in some scenarios, such as when the web page was opened in a new window or tab.
Method 5: How to Refresh the Page Using location.reload() with a Delay
If you want to add a delay before refreshing the page, you can use the setTimeout() function in combination with the location.reload() method.
This allows you to specify a time interval in milliseconds before the page is reloaded, giving you control over the timing of the refresh.
// Refresh the page after a delay of 3 seconds setTimeout(function()< location.reload(); >, 3000); // 3000 milliseconds = 3 seconds
Pros of Using location.reload() with a Delay
- It allows you to control the timing of the page refresh by adding a delay.
- It provides flexibility in scenarios where you want to refresh the page after a certain event or action.
Cons of Using location.reload() with a Delay
- It may cause a delay in the page refresh, which can impact user experience.
- It may not work as expected in scenarios with unstable or slow network connections.
Wrapping Up
In this article, you have learned the different ways to refresh a page in JavaScript. Each method has its pros and cons, which should make it easier for you to choose the best method for your web development project.
When using any of these methods to refresh a page, it’s important to consider the impact on user experience, data loss, and browsing history.
I hope this article helps you understand how to reload a web page in JavaScript and choose the appropriate method for your specific use case.

Location Reload Method: How to Reload a Page in JavaScript
JavaScript Location.reload() method provides means to reload the page at current URL.
The syntax is the following:
object.reload(forcedReload); , where forceReload is an optional parameter.
To simply reload the page, you can input window.location as object.
Optional parameters force reload is a boolean value, which if set to:
True reloads the page from the server (e.g. does not store the data cached by the browser):
False reloads the page using the version of the page cached by the browser.
window.location.reload(false);
False is the default parameter, so if left blank, object.reload() reloads the page using the broswer’s cached data, i.e. is identical to using the method as object.reload(false) .
To create the effect of browser-provided “Refresh”-option, you may want to create HTML-button and do either of the following:
- assign on-click event to the button with the function that uses the method, where the button looks similar to
Example:
// Reload the current resources from the server window.location.reload(true); // Reload the current resources from the browser's cache window.location.reload();
This will reload the page at the current URL from the server.
