GET- GET is basically used for getting the data from the server sometime cached.

The $.get method is used in jQuery to get the data.

$.get(URL,callback);

url spicifies the url you wish to request.

callback function is the name of the function you want to call the executed code.

ex

$("button").click(function(){
    $.get("demo_test.asp", function(data, status){
        alert("Data: " + data + "\nStatus: " + status);
    });
});

POST- POST is also used for the same but it never cached the data and used to send the data with the request.

$.post() is the method for getting data in jQuery.

$.post(URL,data,callback);

url is the parameter you want to request.

data is the data that can be send with the request.

callback is the function can be called after the executed code.

    $.post("demo_test_post.asp",
    {
        name: "Donald Duck",
        city: "Duckburg"
    },
    function(data, status){
        alert("Data: " + data + "\nStatus: " + status);
