    <p>I'm experimenting with <a href="https://github.com/blueimp/jQuery-File-Upload" rel="noreferrer">Blueimp's jQuery-File-Upload</a> plugin, which judging by the <a href="http://aquantum-demo.appspot.com/file-upload" rel="noreferrer">demo</a> looks very promising.</p> <p>It's really easy to implement:</p> <pre><code>var $uploadButton = $("#fileop-upload");// &lt;input type="file" id="fileop-upload" [etc] /&gt; $uploadButton.fileupload({ url : "//domain/path/to/receive-uploaded-files" }); </code></pre> <p>The selected files are uploaded fine without refreshing the page as expected, but of course with a minimal configuration like this the user won't get any notification. Here's where the plugin's callbacks would come in handy.</p> <p>According to the documentation there are two ways to define callbacks. For example the <code>add</code> event (which fires whenever a file is selected for uploading) can be added in the original configuration object like this:</p> <pre><code>$uploadButton.fileupload({ add : addFileListener, url : "//domain/path/to/receive-uploaded-files" }); </code></pre> <p>or alternatively:</p> <pre><code>$uploadButton.bind("fileuploadadd", addFileListener); </code></pre> <p>However I've found that only the first approach works, the second one doesn't do anything.</p> <p>It is even more curious that no other callbacks -- especially <code>progress</code> and <code>start</code> -- seems to be firing not matter how I bind them:</p> <pre><code>$uploadButton.fileupload({ add : addFileListener, progress : progressListener, start : startListener, url : "//domain/path/to/receive-uploaded-files" }); </code></pre> <p>or</p> <pre><code>$uploadButton.fileupload({ add : addFileListener, url : "//domain/path/to/receive-uploaded-files" }); $uploadButton.bind("fileuploadprogress", progressListener"); $uploadButton.bind("fileuploadstart", startListener"); </code></pre> <p>I have the referred listener functions defined, and the code doesn't report any errors or warnings.</p> <p>What is the explanation for the <code>.bind</code> method's failure, and why doesn't the <code>progress</code> or the <code>start</code> listeners ever activate?</p>

    1. COI'm at the same point fighting with blueimp uploader callbacks, trying to implement an swfUpload-style Flash-bashed component solely to handle the file selection dialog to add multiple file selection to IE.

    2. COJust out of curiosity, can you confirm what jQuery and uploader versions you are using? I'm using jQ 1.5.2 and the 4.4.2 version of the upload plugin.

    3. COI've used the most recent, freshly downloaded versions of jQuery and the upload plugin. Anyway, I've moved away from this plugin at the moment and have developed a purely File API based solution (http://blog.new-bamboo.co.uk/2010/7/30/html5-powered-ajax-file-uploads) which only works with FF4+, Chrome and Safari, but luckily this is acceptable for my purposes now.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
