Javascript - Refreshing div or page once with JS or jQuery / Ajax

Refreshing a div or the entire page once using JavaScript, jQuery, or Ajax can be useful in various scenarios, such as updating content dynamically without a full page reload. Below are different approaches to achieve this:

Refreshing a div with Ajax

Using jQuery to refresh a div with Ajax is straightforward. Here's an example where a div with the ID #content is refreshed by fetching new content from the server:

HTML

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Refresh Div Example</title> <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script> </head> <body> <button id="refreshButton">Refresh Content</button> <div id="content"> <!-- Initial content --> <p>This content will be refreshed.</p> </div> <script src="script.js"></script> </body> </html>

script.js

$(document).ready(function() { $('#refreshButton').on('click', function() { $('#content').load('/path/to/your/server/endpoint'); }); });

In this example:

  • When the #refreshButton is clicked, jQuery's .load() method is used to fetch new content from the specified server endpoint and replace the content inside the #content div.

Refreshing a div with Vanilla JavaScript and Fetch API

You can achieve the same result using vanilla JavaScript and the Fetch API.

HTML

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Refresh Div Example</title> </head> <body> <button id="refreshButton">Refresh Content</button> <div id="content"> <!-- Initial content --> <p>This content will be refreshed.</p> </div> <script src="script.js"></script> </body> </html>

script.js

document.addEventListener('DOMContentLoaded', function() { document.getElementById('refreshButton').addEventListener('click', function() { fetch('/path/to/your/server/endpoint') .then(response => response.text()) .then(data => { document.getElementById('content').innerHTML = data; }) .catch(error => console.error('Error fetching content:', error)); }); });

In this example:

  • When the #refreshButton is clicked, the Fetch API is used to get new content from the server. The content is then placed inside the #content div using innerHTML.

Refreshing the Entire Page Once

To refresh the entire page once using JavaScript, you can use the location.reload() method. Here's how you can do it:

HTML

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Refresh Page Example</title> </head> <body> <button id="refreshButton">Refresh Page</button> <script src="script.js"></script> </body> </html>

script.js

document.addEventListener('DOMContentLoaded', function() { document.getElementById('refreshButton').addEventListener('click', function() { location.reload(); }); });

In this example:

  • When the #refreshButton is clicked, the entire page is reloaded using location.reload().

Refreshing a div Automatically After Page Load

If you need to refresh a div automatically after the page loads, you can trigger the Ajax call once the document is ready:

HTML

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Auto Refresh Div Example</title> <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script> </head> <body> <div id="content"> <!-- Initial content --> <p>This content will be refreshed.</p> </div> <script src="script.js"></script> </body> </html>

script.js

$(document).ready(function() { $('#content').load('/path/to/your/server/endpoint'); });

In this example:

  • The #content div is automatically refreshed with new content from the server as soon as the document is ready.

By using these methods, you can dynamically refresh a div or the entire page as needed in your web application.

Examples
