Queue Priority

Demo uploads land in a temporary store and are swept after 60 minutes. To keep files, handle FileUploaded — see Single File for the complete save pattern.

Priority Queue Ordering

Assign priority levels to files in the upload queue. Higher priority files are uploaded first regardless of when they were added.

What you should see: files upload in the priority order you assign rather than selection order - with concurrency 1 the order is strict and visible.

var uploader = AjaxUploader.create('#uploader', {
 uploadUrl: '/ajaxupload.axd/upload',
 multiple: true,
 autoUpload: false,
 concurrency: 1,
 onSelect: function(files) {
 files.forEach(function(f) {
 // Default priority: normal
 // Change with uploader.setTaskPriority(taskId, 'high');
 });
 }
});

// Priorities: 'high', 'normal', 'low'
