Ajax Xmlhttprequest Object
Without the support for this object, the browser would not be able to exchange data with the web server and update parts of the page without reloading the entire page. With Ajax, we can make GET and POST HTTP requests. However, there are some limitations to XMLHttpRequest object. These are mainly for security reasons. First, this object can only make HTTP(S) requests. References to File URLs are not supported. Secondly, it can make requests only to the same domain as the currently loaded page....
