Get JSON from response object

<html>
<body>

    <form action="login.do" method="post">
        //.....

        <input type="submit" value ="send">
    </form>
</body>
</html>

In my servlet I will be handle the request and send the json response back. How can I get the json object from the response ?

But we can do this by calling a function when we click the button.

function(){
    $ajax(
        url:"login.do"
        success: function(data){
        //..... 
        }
    )
}

is there any way to do this? Or only using the function call we can do it?

You could set the dataType to json, or you could use the short cut method $.getJSON().

$.getJSON(your_url, function(data) {
  // data here is already an object.
  console.log(data);
});

EDIT: getJSON will use GET request type, for POST, you could do 

$.post(your_url, function(data) {
  // data here is already an object.
  console.log(data);
}, 'json');

first argument of success callback that you call data is the json object so long as you include dataType:'json' in ajax options or use shorthand $.post(url[,data][,function(json){}),'json']) method

Read about success callback in $.ajax API :

http://api.jquery.com/jQuery.ajax/

EDIT: Using deffered method

var ajaxCall= $.post( url, dataToServer,'json')


 $.when( ajaxCall).then(function(data){
     var json =data;
 })
