Hi,
I have a simple page that submits a form via Ajax. If I leave both
fields blank i get the following response in JSON from the server.
{"errors":{"lastName":"Required","firstName":"Required"}}
I have coded the js to check for errors and then update the page based
on them.
What I would like to do is iterate over the errors returned rather
than have to hard code each error check. So i could use the lastName
and firstName from the JSON, then append '.error' and use the
firstName.error to lookup the span to then set the error message in.
Is this possible?
Below is my html page.

<script type="text/javascript">
function submitTheForm() {
// rest the errors
$('firstName.error').innerHTML='';
$('lastName.error').innerHTML=''
$('example').request({
requestHeaders: {Accept: 'application/json'},
onSuccess: function(transport){
var json = transport.responseText.evalJSON();
var errors = json.errors;
if ( errors.firstName != null ) {
$
('firstName.error').innerHTML=errors.firstName;
}
if ( errors.lastName != null ) {
$
('lastName.error').innerHTML=errors.lastName;
}
},
onComplete: function(){ alert('Form data
saved!')},
onFailure: function() { alert('Failed!')}
})
return false;
}
