Encrypted client-side storage with dojo

A couple of days ago, Nicholas Zakas wrote an article about secure client side storage. I think the scenario he mentioned (working from a cyber cafe) is not unsafe by nature, and could be well handled by an application. Nonetheless, client side storage such as localStorage still is subject to DNS spoofing attacks (which is [ READ MORE ]

Promises with dojo – a lightweight alternative to dojo.Deferred

Update: Micheil Smith had a cool idea to improve this and posted it in the comments. I have updated the test page and the code examples to reflect his idea. Thanks Micheil! Update II: Ben Hockey proposed to do the whole thing without using the pub/sub system. I for one think its a good idea, but [ READ MORE ]

Working with the Curve – Advanced Animation with Dojo

If you use animations, you probably use them to animate CSS properties. But this post is about some real bareknuckle animation – using the dojo toolkit. We’ll have a look into dojo.Animation and talk about the curve, the line, easing and rate, and we’ll check out (the somehow undocumented) dojox.fx._core – and see how to [ READ MORE ]

persistent local storage with dojo

Last year, Brian Leroux’s Lawnchair caught my interest – it is an easy and fast way to access local persistant local storage. Uh, persistant local storage? Ahm, yeah, in case you don’t know, that means a client-side storage, be it in a browser, or in an Air app. It’s not very popular, but that concept has been [ READ MORE ]

More fun with strings: dojo.string.contains()

In the series “convenience wrappers for small tasks that increase code readability”, today contains() is starring. Having a contains() method could also serve another purpose: to maybe prevent people from using match() to find out if a string contains a given substring (what is still proposed in some JS tutorials out there…). So, I want [ READ MORE ]

dojo.string.beginsWith()

Most cases where you find String.substr() in the wild are to check if a given string begins with a certain other string. Be it checking for a prefix or sorting out zipcodes that begin with certain numbers. And because code readability is a good thing (really, it is important), it would be nice to have [ READ MORE ]

A collapsible fieldset as dojo widget

Though many people would disagree, I for one like to use fieldsets to structure complex forms. Even better do I like fieldsets that are collapsible. As there is no such fieldset with dojo, I decided to write my own widget. While doing so, I learnt an interesting lesson… First, I wrote it pretty simple, inheriting the widget [ READ MORE ]

Safari and window.open – How to do it

There is still some traffic coming in from people who are searching for how to deal with the safari popup blocker. So I thought it might be nice to also tell what you can do about it – as most people want solutions, not backgrounds… So, here you go: It’s pretty simple, really. What to do? Well, [ READ MORE ]

3D Canvas Walker revisited

One of the things that fascinated me most about computers since I was a teen, was their ability to simulate a three-dimensional space where one could move around in. That’s why I was so intrigued when I read Jacob Seidelin’s post about “Creating pseudo 3D Games“. I had to play around with it, as I wanted [ READ MORE ]

Safari and window.open

Update: If you are interested in how to make window.open work you might want to also read the follow-up: Safari and window.open – How to do it Working on a project these days, I noticed that the only call to window.open in that app did not work in Safari. Looking into it, I found that it [ READ MORE ]
