jQuery: Retrieve Ajax Data at 10-Second Intervals

When designing a feedback display that incorporates real-time data retrieval, it's important to implement a method that updates the displayed content periodically. This can be achieved using jQuery's powerful Ajax capabilities.

To set up a feedback div that showcases new entries every 10 seconds, you can utilize the following approach:

1. Define a Function to Retrieve Feedback: Create a function named get_fb that executes an Ajax call to retrieve feedback data from a server-side script, such as feedback.php.
2. Configure Ajax Call Parameters: Within the get_fb function, specify the type of request (POST), the URL to send the request to (feedback.php), and set async to false to ensure the call is synchronous.
3. Handle Retrieved Data: Upon successful retrieval of feedback data, update the HTML content of your feedback container (div.feedback-box) with the received data.
4. Schedule Automatic Retrieval: To display new feedback entries at regular intervals, establish a timer using setInterval or setTimeout. Configure the timer to call the get_fb function every 10 seconds.

Here's an improved example based on your provided code:

<code class="javascript">function get_fb(){
    var feedback = $.ajax({
        type: "POST",
        url: "feedback.php",
        async: false
    }).responseText;

    $('div.feedback-box').html(feedback).delay(10000).queue(function() {
        setTimeout(function(){get_fb();}, 10000);
    });
}</code>

Note: This approach schedules the next retrieval after the previous one has been completed. You can adjust the timing as needed to optimize display performance.
