Get JSON from response object
Question
<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;
})
