Question

update: I would like to pass the var value to the server

hello,
same old, same old … 🙂

I have a form called <form id="testForm" action="javascript:test()"> and a code area called <code id="testArea"></code>

I am using this code to stringify and display the data in the code area:

var formData = form2object('testForm');
document.getElementById('testArea').innerHTML = JSON.stringify(formData, null, '\t');
var value = JSON.stringify(formData, null, '\t');

What I want is to send this data to a JSON file.
I’ve been working on this project : http://ridegrab.com/profile_old/ and if you press Submit Query button you will see the head of the page populate.

Also I want use this piece of script to send data:

    function authenticate(userName, password) {
    $.ajax
    ({
        type: "POST",
        //the url where you want to sent the userName and password to
        url: 'username:password@link to the server/update',
        dataType: 'json',
        async: false,
        //json object to sent to the authentication url
        data: '{"userName": "' + userName + '", "password" : "' + password + '"}',
        success: function () {

        alert("Thanks!"); 
        }
    })
}

Again, all I want is to be able to send that JSON data to the server. My server is set up to update or POST the data in the right place.

‘data’ should be a stringified JavaScript object:

data: JSON.stringify({ "userName": userName, "password" : password })

To send your formData, pass it to stringify:

data: JSON.stringify(formData)

Some servers also require the application/json content type header:

contentType: 'application/json'
