In this tutorial, I show How to use jQuery AJAX to implementing this.

There are two ways to send AJAX request on specified time –

  • By setInterval() and
  • By setTimeout() JavaScript functions.

Both do the same work but they are reliable for certain cases, which I discuss in this tutorial.

In this tutorial, we learn how you can Return JSON response or data from AJAX request. We are using jQuery and PHP for implementing this.

What is JSON?

JSON stands for JavaScript Object Notation, it is a data interchange format which is also been used to passing data from the server.

It is best and effective way to return data when you want to return multiple values from AJAX request. We couldn’t directly return an array from AJAX, it must have converted in the valid format.

In this case, you can either use XML or JSON format. I generally prefer JSON, it very easy to use. I am already used in my some of the previous jQuery AJAX tutorials.

Sometimes, we have a requirement to make another element dependent on another element selection.

For example, when you go for the Registration to the website when you select a country according to that State Dropdown is filled.

You can do this with only PHP but it required you to submit every time on selection.

This solves your problem but it is little frustrating because it submits every time even if the selection is right or wrong and this is not every user-friendly.

For making it better you can use AJAX with jQuery it loads new data and removes old one on each selection.

What in the Demonstration ?

Creating a Department drop-down list and based on the option selection show all existing users of that department on another Dropdown.
