[Proto-Scripty] Re: IE8 responseXML ?
Hi Jason,
the way you write it is good even in IE.
When write onComplete: parent_response() , you launch the function
at initialisation time, and the AJAX was not call, so you input is
undefined. If you test alert(originalRequest) you should also have
undefined.
When should this be launched, then? I thought onComplete called the
callback function after the entire ajax call had completed, regardless
of success/failure ?
In fact by writting parent_response(), it indicate that you execute
the function on the creation of the AJAX request, and the retruned of
the execution of the function value will be used for the onComplete.
So the onComplete value will be uindefined (as you return nothing in
the function).
By setting parent_response, you copy the function definition to the
onComplete parameter.
This is the big difference.
For your trouble, what is the response text of the AJAX request ??
you should check it too, in case xML was not recognize by IE and set
as text.
It definitely returns XML .. It's something like this :
Departments
ou name='foo' value='bar' /
ou name='baz' value='qux' /
/Departments
The originalRequest in your parent_response function is in fact an
response Object, go and see the API doc at
http://prototypejs.org/api/ajax/response
If the originalRequest.text value inside the function is your XML
document, it should be a problem in header not recognize by IE.
in that case, you should create an XML document by yourself with the
returned text or modify header.
One thougth, is it a well formed XML, beginning with xml ... asthe
root tag ? it could also be a reason.
To know what contain originalRequest just paste on this thread the
retruned value of:
$H(originalRequest).inspect(). We will have all info on that object.

The parent_response function will parse that, create what I need, and
display it. The problem is, originalRequest doesn't seem to get set, or
if it does, it's not by what I'm expecting.
Should I call the AJAX some other way instead of via the body onload?

function parent_response(originalRequest) {

This is all fired off via a body onload='update_parent'
This works perfectly in Firefox. However, in IE8, it is failing with no
errors. The alert in parent_response() does not get triggered in IE8.
If I change the onComplete: to read :
onComplete: parent_response()
Then the alert triggers, but it pops up as undefined. How do I properly
handle this so it works cross-browser? ie, what object should I be
sending to get to the responseXML value?
Thanks,

I have discovered more.. Adding an onException block like this :
function update_parent() {
/** retrieve XML */
var root = 1;
var myAjax = new Ajax.Request(url,
{
method: 'get',
parameters: {parent_id: root},
onSuccess: function(response) {
alert('SUCCESS: ' + response.responseText);
},
onFailure: function(response) {
alert('FAILURE: ' + response);
},
onException: function(request,error) {
alert('EXCEPTION: ' + error.message);
},
onComplete: function(response) {
alert('COMPLETE: ' + error.message);
}
}
);
}
ends up with IE8 popping up an EXCEPTION: Access is denied. message..
Access to what, though?

[Proto-Scripty] Re: IE8 responseXML ?
AHA!!! I have resolved this. We had a base element in the head of the document. Apparently this is to reference where the images/css/etc are. This causes IE8 to prevent javascript from retrieving a page due to security restrictions. I'd feel dumb about it if I didn't think this was a really poor way to secure javascript. Why they can't compare the destination domain of the request to the domain of the original HTML, I don't know. Either way, I have both resolved the problem and learned a bunch about prototype/javascript in the process. Thanks a lot, david, I really appreciate the help! -- --- Jason Frisvold xenopha...@gmail.com --- I love deadlines.
