How to Update Webpage Content Dynamically Using AJAX Without a Reload?

Change HTML Page Contents Dynamically Without Reloading

You desire to update the contents of a webpage dynamically, specifically a div, without triggering a page refresh. This can be achieved through AJAX (Asynchronous JavaScript and XML).

jQuery Approach

1. Define JavaScript Function:

   <code class="javascript">function recp(id) {
     $('#myStyle').load('data.php?id=' + id);
   }</code>

2. Add Event Handlers:
   Replace the onClick handlers in your HTML with the recp function:

   <code class="html"><a href="#" onClick="recp('1')" > One   </a>
   <a href="#" onClick="recp('2')" > Two   </a>
   <a href="#" onClick="recp('3')" > Three </a></code>

3. Create PHP Script:
   Create a separate PHP file, such as data.php, that handles the data retrieval:

   <code class="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>

4. Load Data Dynamically:
   When a link is clicked, the recp function uses AJAX to load the data from data.php into the div with the id 'myStyle':

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

Note: Ensure that the path to data.php in the jQuery load() function is correct and that the PHP file has appropriate permissions.
