JavaScript is a widely used scripting language, mainly used for interactive and dynamic effects on web pages. Refreshing the page is a very important part when designing a web application, and in JavaScript, refreshing the page is a very basic task. In this article, we will discuss how to refresh the page in JavaScript.
Why we need to refresh the page
First of all, we need to know why we need to refresh the page. In a web application, refreshing the page can cause the application to reload data or perform other operations. For example, when a user adds or removes items from a shopping cart web page, some numbers or information needs to be updated in real time. To keep the data up to date, you can use the refresh method in JavaScript to update the interface and data.
Refresh method in JavaScript
JavaScript provides a variety of methods to refresh the page. These methods allow for better user experience and interaction with our web applications. Below, we will introduce several commonly used JavaScript refresh methods.
1. Use the location.reload() method
This method can reload the current page. This method is invalid, if we want to reload other web pages, we need to add the URL address of the web page in brackets. The following are two sample codes:
//Reload the current page
location.reload();
//Reload other web pages
location.reload("http: //example.com");
When using this method, the entire page will be reloaded, including all cached data and local storage data. Therefore, this approach comes at a very high performance cost.
2. Use the location.replace() method
This method can be used to replace the current page with a new page. What it does is replace the URL of the current web page, rather than simply reloading it. The following is a sample code:
//Replace the current web page
location.replace("http://example.com");
When using this method, the browser will not Add URL to browser history. Therefore, the user cannot return to the old page by clicking the browser's back button, but jumps directly to the new page.
- Use the location.reload(true) method
This method is similar to location.reload(), but it forces a reload of the web page and ignores the cache. If caching was used on a previous page load, the page will be re-downloaded when this method is called to ensure the latest data. The following is a sample code:
//Force reloading of the current page
location.reload(true);
When using this method, if our website uses a large number of media files, This approach will have a high performance cost.
- Use window.location.href method
This is a very simple refresh method, which uses the window.location.href property to refresh the page. The following is a sample code:
//Refresh the current page
window.location.href = window.location.href;
When using this method, the browser will reload the current page , and update all cached data and local storage data.
Conclusion
In this article, we introduced several commonly used JavaScript refresh methods. These methods can be used to refresh the page in JavaScript. For each scenario, we need to choose the appropriate method to refresh. In applications, there are many places where refresh operations are required. However, for some applications, frequent refreshes may affect application performance. Therefore, we need to use these methods very carefully. The best practice is to minimize refresh operations while maintaining the user experience.
