Ding, ding, ding. Looks like that's it. In my PHP script, this is what
I did to test...
try {
throw new Exception ( 'Something I made up' );
}
catch ( Exception $e ) {
header ( 'HTTP/1.0 500 Internal Server Error', true, '500' );
echo $e-getMessage();

My error callback picks it up nicely and reports the message in

Thanks again.
[jQuery] HowTo: Trigger error callback in ajax request
I have an ajax request being sent to a PHP script. If that script
captures an error, I'd like it to echo that error and return whatever
it needs to return to trigger the error callback in my ajax call. I
can't seem to find what that is. Is it a non-200 status code? Simply
throwing an error (throw new Exception()) just triggers the success
callback with the error text (not unexpectedly, of course).
I'm using the jQuery form plugin and using the .ajaxSubmit() method,
but I suspect the answer would be the same for a core .ajax() call.
My simplified case looks like this:
$(document).ready ( function() {
$( '#CommercialVendorAddForm' ).submit (
function() {
$(this).block();
$(this).ajaxSubmit ({
beforeSubmit: function() {
alert ( 'validating' );
},
success: function ( responseText, responseCode
) {
alert ( 'success' );
alert ( responseText );
},
error: function() {
alert ( 'An error has occured. Your
application could not be
submitted.' );
},
complete: function() {
$( '#CommercialVendorAddForm'
).unblock();
}
});
return false;
}
);
});
I can't believe that there's not a way to force the error callback to
receive the response if the server page returns an error, but what is
that way?
Thanks.

[jQuery] Access Elements Rendered in a Thickbox
Hey all - I'm looking for/wondering whether there is a way to access an element loaded in a thickbox. I have a page that launches thickbox to load a form. I need to be able to set a click() event listener on the submit button of that form so that I can submit the form via ajax. Unfortunately, I can't come up with a clever way of doing that. Any ideas? I tried (just for the sake of eliminating the obvious) applying the event listener on document ready, but no luck, of course, since I assume that the form's submit button doesn't exist until the thickbox is loaded. Is there any way to make this happen? Thanks.

Seems that IE, in its infinite wisdom, thinks that the hrefs created
by the multifile upload code aren't good enough and prepends the rest
of the page URI to them at runtime. The href coded a
href=#multimulti_0Delete/a, rendered in IE, is transformed into
a href=http://www.mydomain.com/survey#multimulti_0;Delete/a.
As a result, the attribute-begins-with selector ([attribute^=value])
doesn't work. I replaced it with the attribute-contains selector
([attribute*=value]) so that the code will work in both IE Firefox.

A high level end-to-end process looks like this:
1. User selects a file to upload
2. File is uploaded via the ajax file upload plugin and validated
3. If an error is thrown (dimensions incorrect, file size too large,
etc.), the error is displayed and the delete link is triggered so that
the file is removed from the display.
Any insight would be much appreciated. I don't see any indication in
the jQuery docs that this type of selector shouldn't work in IE...
Thanks.

[jQuery] Interacting with the MultiFile Plugin
I have a form that is using both the ajaxFileUpload and the MultiFile
plugins. When a user selects a file for upload, the change event
uploads the file via ajax for validation. If an error occurs, I need
to remove the file from the MultiFile queue. I can (and have)
manually removed the elements, but that doesn't decrement the maxfile
counter, of course.
The easy way to do all of this is to trigger the MultiFile function
that is called when the user deletes the file from the UI, but I can't
figure out how to do that or, for that matter, if it's even possible.
Here is a snippet from within my $.ajaxFileUpload() where I'm manually
removing the UI components:
success: function ( data, status ) {
try {
var index = /\d+$/.test ( input.name ) ? input.name.replace (
/^.+
(\d)+$/, '$1' ) : 0;
/**
* If there's an error in the upload process, remove the
relevant
* UI elements.
*/
if ( data['error'].length 0 ) {
$('#multi_0_' + index ).remove();
$('a[href^=#multimulti_]:last').parent().remove();
/** TODO: have to decrement the counter within the
MultiFile
object...how? */
throw ( data['error'] );
}
else {
// Debug
// alert ( data['files'] );
$('form').prepend (
'input type=hidden ' +
'id=uploaded' + index + ' ' +
'name=uploaded' + index + ' ' +
'value=' + encodeURI ( data['files'] ) + ' ' +
'/'
);
}
}
catch ( e ) {
alert ( 'Error: ' + e.message );
}
},
Any help would be much appreciated.
Thanks.

[jQuery] SOT : CurvyCorners Plugin Issue in IE
I tried to post this question on the CurvyCorner forum, but it wouldn't let me activate my registration, so I thought I'd try here in the hopes that other users of the plugin can offer some insight. The plugin works great in Firefox and IE6 (my test browsers for now), but in IE, as soon as I add an opacity value to the container the rounded corners disappear and I'm left with just the original container. In Firefox, the opacity doesn't bother the plugin at all. What I have is an unordered list item (not a div) whose corners are to be rounded. The corners are rounded nicely and, at this point, looks exactly the same as in Firefox. I then apply filter: alpha(opacity=85) to the li (opacity=.85 in Firefox). Firefox handles the property fine, but IE just drops the elements that create the corners. Any idea why the application of an opacity property would have such a dramatic effect? Is there any way to avoid this (while maintaining the opacity specification)? Any thoughts would be greatly appreciated. Rob Wilkerson
[jQuery] AJaX Error
I don't think this is jQuery specific, but I'm using jQuery and this
community is helpful as hell, so I thought I'd post to see whether
anyone had any thoughts. I'm making an AJaX call to a PHP page that
returns a lot of data in JSON format.
1. The PHP page is doing a lot of work and could take several minutes
(or more) to return the data.
2. The Apache request timeout is unlimited.
3. When the error is returned, the exception object's message
property reads: syntax error with no description.
4. When returning less data (i.e. 3 days rather than 7), the request
is returned just fine.
5. Firebug indicates that the request never completes. The
Response tab still says Loading... even after the call has errored
and quit.
The code:
$.ajax ({
type: 'POST',
url: '/reports/_report.php',
dataType: 'json',
data: filter,
global: false,
timeout: 90, // 15 minutes
success: displayReport,
error: function ( request, errtype, e ) {
alert ( 'An error occurred while loading this report. ' +
e.message
+ '(' + e.description + ')' );
$( '#out-' + report ).empty().append (
'strongemError/em/strong' );
},
complete: function() {
$(indicator).css ( 'visibility', 'hidden' );
$(src).css ( 'opacity', '1' ).bind ( 'click', runReport );
}
});
If anyone has any thoughts on what might be happening, I'd really
appreciate it. I Googled until my fingers bled, but couldn't find
anything that seemed to make a difference. I'm hoping that maybe I've
just been looking at it for too long and am missing the obvious.
Thanks.

[jQuery] Re: Help Modifying the Action Page of an AJaX Form
Okay, I found a way to do what I want to do, but ran into something
else. Using the jQuery Form plugin, I've managed to serialize the
form inputs and, via ajax, post the values to a page which returns a
JSON result:
$('[EMAIL PROTECTED]/run.png]').click (
function ( e ) {
var data = $('#filter').formSerialize();
var report = this.id.replace ( /\w+-(\w+)/, '$1' );
data += 'report=' + report;
$.ajax ({
type: 'POST',
url: '/reports/' + report + '.php',
dataType: 'json',
data: data,
success: displayReport
});
}
);
The problem is that formSerialize() doesn't properly encode checkbox
values. Given a set of checkbox options with the same name, normal
form encoding passes the values as a comma-delimited list. The
serialized value just applies them separately to the query string so
that the only one that is read is the last one.
Instead of myselections=value1,value2, value3, I get
myselections=value1myselections=value2myselections=value3.
Has anyone else seen this? Am I missing something?
Thanks.

[jQuery] Re: Help Modifying the Action Page of an AJaX Form
You can look at the spec here: http://www.w3.org/TR/html401/interact/forms.html Hmmm. I hadn't read the spec. I'm used to dealing with these things on the server side and never really had to think about how they were handled. PHP doesn't seem to be handling it the same way ColdFusion and, as Jeff pointed out, .NET does. All the $_POST value is reporting is the last value. I'll do some more digging on the server side and take another look at my code to make sure I don't have some other bug. Thanks for setting me straight.
[jQuery] Re: Help Modifying the Action Page of an AJaX Form
Apologies for my ignorance. I've been away from PHP for a long time and guess I forgot that I had to name my checkbox fields with array notation (e.g. input type=checkbox ... name=mycheckbox[] /). Once I did that and used implode() on the server side I got what I needed. Thanks.

What you probably need to do is make a request to your server, have it
get http://www.myuri.com/index.htm by some means then return the
