What About jQuery and AJAX ?
For AJAX functionality, jQuery offers various ways.
You may request the text, HTML, XML, or JSON of your server site data using both HTTP Get and HTTP Post methods using JQuery's AJAX techniques - and you can load the external data straight into your website's chosen HTML components!
The coding of AJAX can be quite hard without jQuery!
Regular AJAX code might be difficult to write since various browsers have distinct AJAX implementation languages. This implies you'll have to create additional code to test for other browsers. The jQuery team, on the other hand, has taken care of this for us, allowing us to create AJAX capability with only one line of code.
