How to implement a price range slider using JavaScript's XMLHttpRequest Object.

 

 

The range slider can be useful for allowing users to select a specific price range when browsing products. Frequently you will see using this widget in several  sites, especially in ecommerce websites. Today, I will show how to use this price slider with JavaScript and jQuery and PHP.  

This example using mobile UI Two Point range sliders, where you will see start and end ranges  in a single slider.

 

Here is a code example. There are  two files, one is PHP file, which provides a backend code, it receives a range values and returns them back to frontend  when user changes the range values.
 

Follow the steps given below

Code Example:

Step-1

create a PHP file with given name  current_prices.php and copy the given code in it and save. It will receive max and min values from the form.

 current_prices.php

 

<?php echo " Price Min: ".$_GET['min']."<br />Price Max: ".$_GET['max']; ?>


 

 

 

The above PHP file get called dynamically  in JavaScript function: updatePrices() using Ajax request object (XMLHttpRequest Object.)

 Step-2

 create  a file and copy the below code and save it. Open in server and execute it. And check the output.

 

 price-range-slider.php
