jQuery Pjax is a lightweight jQuery plugin used to update parts of a webpage through AJAX technology. It allows for partial page refresh without reloading the entire page, thereby enhancing user experience. This article will provide a detailed guide on how to use jQuery Pjax to achieve partial page loading.

Preparation

1. Include jQuery Library and jQuery Pjax Plugin

Before using jQuery Pjax, make sure to include the jQuery library and jQuery Pjax plugin. You can do so by adding the following scripts:

<script src="https://code.jquery.com/jquery3.6.0.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery.pjax/2.0.1/jquery.pjax.min.js"></script>

2. Configure Pjax

Prior to utilizing jQuery Pjax, configure Pjax with basic settings such as timeout duration, request type, and data type as shown below:

$(document).ready(function() {
    $.pjax.defaults.timeout = 5000; // Set timeout duration in milliseconds 
    $.pjax.defaults.type = 'GET'; // Set request type (default is 'GET')
    $.pjax.defaults.dataType = 'html'; // Set data type for response (default is 'html')
});

Using jQuery Pjax

1. Trigger Pjax Request

To achieve partial page loading with jQuery Pjax, you need to trigger a Pjax request. This can be done by:

// Trigger Pjax request for the current page
$.pjax.reload();

// Trigger Pjax request for a specific URL
$.pjax('#someelement', { url: 'someurl' });

2. Handle Returned Data

Upon successful retrieval of data from the Pjax request, utilize the success callback function to manage the returned data and append it to a designated element:

$.pjax({ url: 'someurl', success: function(data) {
    $('#someelement').html(data);
}});

3. Handle Error Situations

If an error occurs during the Pjax request, use the error callback function to handle the error case and display an error message:

$.pjax({ url: 'someurl', error: function() {
    alert('Pjax request failed');
}});

Important Notes

Ensure that the server supports the correct HTTP header information. Pjax relies on specific HTTP header information returned by the server to identify the content that needs to be partially refreshed.

Make sure the following HTTP headers are correctly set: XPJAX, XPJAXID, XPJAXTYPE, XPJAXCONTENTTYPE, and more.

Stay vigilant about server-side configurations to ensure smooth functioning of jQuery Pjax.
