How Can I Alter HTML Page Content Dynamically Without Refreshing the Page Using AJAX?

Change HTML Page Contents Without Reloading Using AJAX

You want to update the content of a DIV element without refreshing the page when a link is clicked. Here's how you can achieve this using PHP and AJAX:

PHP Configuration:

• Create a PHP script (e.g., data.php) that connects to your database and retrieves the data based on the parameter id.

HTML Markup:

• Create a DIV element with an identifier (e.g., myStyle).
• Add links with onClick handlers that call a JavaScript function with the id as an argument.

JavaScript with jQuery:

• Include the jQuery library.
• Define a recp function that uses AJAX to load the data from data.php into the myStyle DIV.

Example Code:

HTML:

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

<a href="#" onclick="recp('1')">One</a>
<a href="#" onclick="recp('2')">Two</a>
<a href="#" onclick="recp('3')">Three</a>

<div id="myStyle">
</div></code>

PHP:

<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>

Once you have implemented this solution, clicking on the links will update the content of the myStyle DIV without reloading the page.
