Does the format matter? If not, this will get you the serialized form:
var value = JSON.stringify($('form').serializeArray());
alert(value);
Then you can pass around value however you like.
UPDATE
If you want something more user friendly you could try something like this. Since you havent provided your HTML, I'm making up a form.
<input id="fullname" type="text" />
<input id="email" type="text" />
<input id="phone" type="text" />
<input id="submitButton" type="button" />
<div id="results"></div>
And the jQuery would be something like:
$('#submitButton').click(function()
{
var value = $('#fullname').val() + '<br/>' + $('#email').val() +
'<br/>' + $('#phone').val();
$('#results').text(value);
});
UPDATE 2 If you are having trouble with the event handlers, you might want to try to stop the bubbling of the event. by adding the event parameter to the function and calling event.preventDefault()
$('#submitButton').click(function(event)
{
//do stuff
event.preventDefault();
});
