Whether you’re a beginner or an experienced JavaScript developer, it’s important to stay up-to-date on the latest advanced techniques.
In this article, we’ll delve into the world of advanced JavaScript and show you how to use Location.reload(true)
to reload a page with one quick command. We know that reloading a page can be a stressful process—especially if your page is filled with code.
But, with Location.reload(true)
, it’s simple and straightforward. Let me show you how it works and why it’s important for any level of developer to understand this powerful technique.
What Is Location.reload(true) JavaScript?
Are you looking to take your understanding of JavaScript up a notch? You’re in luck because the Location.reload(true)
command is one of the most powerful tools available when it comes to browsers and programming.
Location.reload(true)
is an instance method of the location interface included in JavaScript. When called, it refreshes the current webpage, essentially reloading the entire page with a new URL request.
Put simply, this means it will load an entirely new version of the content you’re viewing without any interference from web browsers, such as caching and redirects.
So, why would you want to use this type of function? If you’re looking for an efficient way to update content on a page without loading a new page from scratch, then this command is your best bet.
Not only does it refresh your page just like a regular reload, but it does so without losing any states that might have been set for components on the original page—in other words, no more worrying about losing data due to web browser caches.
Syntax and Example of JavaScript Location.reload(true)
Have you ever tried to reload a page using JavaScript? If so, then you’ll be familiar with the location.reload()
method, which is used to refresh the page. However, sometimes, you want to make sure the webpage is loading from the web server and not from cache—this is where loading a page with location.reload(true)
comes in handy.
The syntax for loading a page with location.reload(true)
is as follows: window.location.reload(true)
. For example, if you wanted to refresh a page called “page1.html” using “location.reload(true)
,” you could use the following code: window.location="page1.html"; window.location.reload(true);
.
When loading a page with location.reload(true)
, it forces your browser to send an additional request to the web server for confirmation that it has the latest version of your webpage cached—this ensures any changes made to your webpage are reflected immediately on reloading the page, instead of displaying an outdated version stored in the cache.
Advantages of Reloading a Page With Location.reload(true)
Using the advanced JavaScript technique of reloading a page with Location.reload(true)
comes with lots of great benefits. If you’ve never tried this technique, now might be the perfect time to start.
Get Updated Content and Data
The main benefit of reloading a page is that you’ll get the newest and freshest version of content and data without having to manually refresh or open a link in a new tab.
Once you’ve written your program, and included this kind of refresh in it, all users will instantly see the updated version when they visit.
Help Performance and Eliminate Glitches
Another great benefit of using this advanced JavaScript method is that it can help boost performance and eliminate glitches on your page.
By regularly refreshing the page and loading only new content, you can make sure users get a fast and glitch-free experience while navigating your website or web application.
Facilitate Ongoing Updates and Changes
Lastly, by using Location.reload(true)
, you can make sure your pages are up-to-date with all the latest changes to content or data—both big and small—without manually updating them each time.
This is especially useful if you have an ever-evolving site that needs ongoing updates, such as an e-commerce store or an online platform for streaming video or music.
When Should You Use JavaScript Location.reload(true)?
When should you use the JavaScript function location.reload(true)
? Well, there are some specific scenarios when this can be used. Let’s take a look at those:
- In situations when you want the page to entirely reload while keeping the current page in view rather than adding a new page to the session history, you can use
location.reload(true)
. This is helpful in JavaScript-heavy applications that rely on client-side logic for navigation as well as when handling mobile webpages and apps that need to be fully reloaded for certain actions or events. - When there are possible changes in the URL or query string parameters from one request to another and you want those changes reflected on the webpage without refreshing the entire page, you can use
location.reload(true)
. This is often useful when making calls between multiple pages within an application and ensuring each holds the correct information without having to navigate away from the current page entirely each time. - If there have been updates made to scripts or elements of a web page that don’t require re-rendering of the web page in its entirety, more optimized techniques exist than
location.reload(true)
. This includes techniques such as DOM manipulation, which updates only parts of a web page rather than reloading all content with code only executed by browsers rather than server requests or AJAX calls with partial data updates sent from backend systems built into an application’s architecture.
Overall, using location.reload(true)
for reloading a web page is a versatile and powerful tool available during the development of complex applications and website designs.
Seven Tips for Working With Location.reload(true) in JavaScript

6. Separate Content From Behavior
When using Location.Reload(true)
, it’s important to keep content and behavior code separate from each other. Keeping these two concepts separate will help ensure that your code is modular, making it easier to debug and maintain in the long run.
7. Automate Tasks With Tools
Finally, consider using a task-automation tool, such as Grunt or Gulp, to help automate tasks related to Location.Reload(true)
. Automation tools can help streamline your development process, cutting down on unnecessary manual labor and ensuring that your code works as it should.
