Hi... I am working in AJAX and use GET and POST method. How can we define HTTP GET and HTTP POST method in ajax and define syntax for any ajax call?

Hi Aaron GET and POST GET is simpler and faster than POST and can be used in most cases. However always use POST requests when: * A cached file is not an option (update a file or database on the server) * Sending a large amount of data to the server (POST has no size limitations) * Sending user input (which can contain unknown characters) POST is more robust and secure than GET GET Requests xmlhttp.open(GETdemo_get.asptrue); xmlhttp.send(); If you want to send information with the GET method add the information to the URL: Example xmlhttp.open(GETdemo_get2.asp?fname=Henry&lname=Fordtrue); xmlhttp.send(); POST Requests Example xmlhttp.open(POSTdemo_post.asptrue); xmlhttp.send(); To POST data like an HTML form add an HTTP header with setRequestHeader(). Specify the data you want to send in the send() method: Example xmlhttp.open(POSTajax_test.asptrue); xmlhttp.setRequestHeader(Content-typeapplication/x-www-form-urlencoded); xmlhttp.send(fname=Henry&lname=Ford); Please refer the below links http://www.openjs.com/articles/ajax_xmlhttp_using_post.php http://www.w3schools.com/ajax/ajax_xmlhttprequest_send.asp Thanks
