[Proto-Scripty] Re: process further
Hi,
I am a newbie too , but I think if processMe() is method of a class , u can
call that method using 'this' like
$('fullname').value = this.processMe(parameter);

Thanks, but I think I one step further. I am assuming an Ajax.request()
has happened, returned and what I am looking at to understand further is
syntax like this:
$('fullName').value = json.fullName;
for an returned parameter fullName and an html element ID of fullName. I am
wondering, can I do
$('fullName').value =processMe( json.fullName);
which I know the obvious is try it. I will, just trying to get an heads
up. I will report back. Also I am assuming that prototpye is processing
that nomenclature $('fullName') segment and just doing a
document.getElementById. Any insight appreciated.

[Proto-Scripty] Re: process further
Hi,
...like this:
$('fullName').value = json.fullName;
for an returned parameter fullName and an html element ID of fullName.
It would be helpful if you gave a more thorough explanation of what
you're looking to do. But, just for the sake of an example, let's
assume:
1. You are sending back properly-formatted JSON with the correct MIME
type in response to an Ajax.Request.
2. The JSON data will have a success flag and firstName and lastName
properties, like this:
{
'success':true,
'firstName': 'Joe',
'lastName': 'Bloggs'
}
3. You want to display the names in the format firstName lastName in
an element that already exists on the page with the ID fullName.
Here's how you can do that:
function showError(errmsg) {
alert(errmsg); // or whatever
}
function showName(elm, obj) {
elm.update(json.firstName + + json.lastName);
}
new Ajax.Request(url, {
// Success handler
onSuccess: function(response) {
var json, elm;
// Get the object containing the data from the request.
// Since you returned it with the correct content type
(application/json),
// Prototype has _already_ deserialized it for you and put it
in the
// member 'responseJSON'. (You don't need to use evalJSON()
unless
// you're not setting the content type correctly.)
json = response.responseJSON;
// Check that the JSON was returned
if (!json || !json.success) {
showError(Couldn't get the name.);
} else {
// Get the fullName element
elm = $('fullName');
if (!elm) {
// Show an error? The element is missing.
} else {
// Set its content from the JSON data
showName(elm, json);
}
}
},
// Failure handler
onFailure: function(response) {
showError(Error getting the name from the server.);
}
});
Hopefully that'll get you headed the right way. Although it doesn't
talk about JSON, this article[1] on the unofficial wiki may also be
helpful in terms of bulletproofing your Ajax requests.

[Proto-Scripty] Re: process further
Hello,
all you have to do (I guess) is set a callback to onComplete.
Something as follow:
// onComplete callback's call
function processJsonPart (myCoolVar)
{
// do something with your returned JSON
return myCoolVarEvaluatedOrValidatedOrAnythingYouWant;
}
// here we call Ajax.request
function clickButtonExample()
{
new Ajax.Request(url, {
onComplete: function(r)
{
var json = r.responseText.evalJSON(true);
$('name').value = foo(json.name);
}
}
}
PS: untested functions.

oops!
'foo' should be 'processJsonPart'
