[jQuery] Re: Interacting with the MultiFile Plugin

I have a form that is using both the ajaxFileUpload and the MultiFile

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 );
}
},
Oh, to see the forest through the trees. It seems to work if I
manually trigger the click event of the link. sigh
$('a[href^=#multimulti_]:last').trigger ( 'click' );
