Ensure the page is always updated by automatically refreshing it with JavaScript each time it

I'm currently working on a web application that makes use of JQuery. Within my javascript code, there's a function triggered by an onclick event in the HTML which executes this line:

$('#secondPage').load('pages/calendar.html');

The calendar.html file being loaded contains javascript that fetches data from a .json file. The issue arises when navigating away from the page using javascript and then returning back to the calendar.html page - it remains cached and does not refresh with new data from the .json file.

Is there a method to include something in the code that would trigger a refresh on that page or retrieve fresh data from the .json? Thank you!

Answer №1

Uncertain about the approach you are taking to load JSON content in calendar.html, but my assumption is that you are utilizing a jQuery function.

You have the option to utilize jQuery.ajax() for loading JSON content and specify cache as false to prevent the browser from caching the response: http://api.jquery.com/jQuery.ajax/

Answer №2

One way to prevent AJAX calls from being cached is by including random parameters in the URL.

Web browsers tend to cache requests with identical parameter values, so adding a random parameter can help avoid this issue. The random parameter doesn't serve any other purpose except to keep the calls uncached.

An example of how you could implement this is:

$('#thirdSection').load('sections/gallery.html?r=' + Math.random());

Do you follow?

Answer №3

Here is a handy trick:

$.ajaxSetup({ cache: false });

By using this code snippet, caching on ajax calls made by jquery will be turned off.
