How to Update Dynamic Content without Page Refresh Using AJAX?

Dynamic Content Updates with AJAX

Problem:

You aim to update the content of a div without reloading the page upon clicking a link.

Solution without Refreshing:

Employing AJAX (Asynchronous JavaScript and XML), you can retrieve updated content without reloading the page.

Implementation:

  1. Handle Link Events with JavaScript:

    Assign JavaScript event handlers to links to invoke the data retrieval function.

    <code class="html"><a href="#" onClick="recp('1')" > One   </a></code>
    Copy after login
  2. AJAX Request with jQuery:

    The recp() function uses jQuery's .load() method to retrieve data from a PHP script without reloading the page.

    <code class="javascript">function recp(id) {
      $('#myStyle').load('data.php?id=' + id);
    }</code>
    Copy after login
  3. Retrieve Data with PHP:

    Create a PHP script (e.g., data.php) that retrieves data based on the ID passed in the URL.

    <code class="php"><?php
    require ('myConnect.php');     
    $id = $_GET['id'];
    $results = mysql_query("SELECT para FROM content WHERE  para_ID='$id'");   
    if( mysql_num_rows($results) > 0 )
    {
     $row = mysql_fetch_array( $results );
     echo $row['para'];
    }
    ?></code>
    Copy after login
  4. Render Updated Content:

    The retrieved data is loaded into the div with id='myStyle'.

    <code class="html"><div id='myStyle'>
    </div></code>
    Copy after login

With this implementation, clicking links updates the div's content dynamically, providing a seamless and responsive user experience without refreshing the page.
