Dive Into Dijit Forms

Wednesday, August 11th, 2010
This entry is part 4 of 4 in the series Dive Into Dojo

As was illustrated with our Dive Into Dijit post, the Dijit library provides an extremely powerful, flexible set of Dojo-based widgets with which you may easily enhance the look and functionality of your web application.  These widgets include drop down / popup menus, dialogs, page layouts, trees, progress bars, and form elements.  When looking at these elements, it’s easy to see that Dijit enhances their presentation but this post will focus on enhancing functionality;  specifically, enhancing a basic form with usability improvements and validation.

DojoX FileUploader Upgrade to Support Flash 10

Monday, December 1st, 2008

I’ve just completed the upgrade of the DojoX FileUploader to make it compatible with Flash Player 10. The FileUploader widget allows for the uploading of more than one file at a time, which is surprisingly still not supported natively by any web browser on the market today.

In Flash versions 8 and 9, a file upload Browse Dialog could be launched using JavaScript code. Users could click an HTML button, which would call a JavaScript function behind the scenes, communicate with a Flash (SWF) file, which would then trigger the browse() method in the SWF. The latest Flash Player has a security feature where the user must click within a Flash-based portion of the user interface to launch the Browse Dialog. This change is to prevent malicious code from continually opening the dialog without user interaction. Working toward this upgrade was a major undertaking that involved a significant rewrite of FileUploader. The results are a success, and in addition to working with the tightened security policies, it was a great opportunity to add many new features:

  • Degradable
  • CDN Support (see below for cross-domain restriction details)
  • POST Data Support
  • Custom Field Name Support
  • Full Event Support
  • Exposed CSS Positioning
  • Dialog Container Detection

The Dojo Toolkit Multi-file Uploader

Tuesday, September 2nd, 2008

Uploader Header

The Dojo Toolkit now has support for multi-file uploads, thanks to the new Deft project. The dojox.form.FileUploader class embeds a hidden SWF file in the page which, when triggered, will open a system dialog that supports multiple file selection, and also file masks, which allows the user to filter their selection by file type.

Replacing the Flash Flickr Badge with Dojo

Monday, June 23rd, 2008

A few weeks ago, some of the guys at SitePen were commenting that I was using Flash on my personal web site for a Flickr Badge. I responded that if Dojo had similar functionality, I would easily replace the badge. A couple of weeks later, Peter Higgins and Bryan Forbes of SitePen rose to the task and created dojox.image.FlickrBadge.

This weekend I had a chance to put their work to the test, and I’m impressed. Using the new Flickr badge is quite easy:
