Java Reference
In-Depth Information
On a successful request, the
handleUsernameResponse()
and
handleEmailResponse()
functions
execute. They no longer manually parse the JSON data into a JavaScript object; instead, they use the
responseJSON
property:
var response = transport.responseJSON;
And finally, you register the button's
click
event listener using the
observe()
method:
$("btnSubmit").observe("click", btnSubmitClick);
