What might be causing the lack of JSON updates appearing on my webpage?

I am facing an issue with my JSON file. After making updates to the file, the changes are not reflected on my webpage. Even after refreshing multiple times, only the old data is being displayed. I am using xampp local server and ajax for retrieving the JSON data in my code.

Any assistance would be greatly appreciated.

This is a snippet of my JSON file:

[
 {
  "name": "Aseem",
  "age":29,
  "salary":50000
 },
 {
  "name": "John",
  "age":23,
  "salary":53000
 },
 {
  "name": "Erica",
  "age":25,
  "salary":52000
 }
]

Answer №1

When the content of something does not appear to be updating, the culprit is often the cache. Web browsers store content that is downloaded from the internet in order to speed up future loading times and reduce the amount of data needed to reload those resources.

You can easily test this yourself by accessing the Developer Tools in your browser (typically done by pressing Ctrl+Shift+I in Google Chrome), navigating to the Network tab, and finding a checkbox labeled 'Disable cache'. By checking this box, you should be able to see the most recent version of the page when you refresh it.

If you prefer to address this issue programmatically, one simple solution is to append a query string to the end of the URL. This tricks the browser into treating it as a new resource, prompting it to request the updated content. The webserver will ignore the query, preventing any unintended consequences. Here's an example:

let noCache = Date.now().toString(16);
url = `${url}?noCache=${noCache}`;

// Make request with updated URL

Answer №2

verify two points

1. Is the ajax data fresh? 2. Make sure to clear your browser cache and attempt it again.
