Oh just pick a time

Posted in interaction design, javascript | Saturday, October 24th, 2009 | No Comments »

So it’s a difficult problem when you’re designing a form that has a lot of time inputs (the one I’m thinking of has up to 4 including a time range). There is the usual, one time box, and an AM/PM dropdown, but that requires typing then clicking, and feels  too tedious, especially the 3rd time.

Then there is the huge dropdown of times, which isn’t too bad for just hours, with which you end up with 24 options, but when you add quarter hours you get 100 items in a huge scrolling dropdown (scrolling dropdowns in themselves can be dubious to some users).

So I did some looking around and found the following options the first of which isn’t the fastest  to use, and doesn’t require the least clicks, but was the most consistent with other elements on the page, and also seemed to have the most development behind it, and I ended up using in my current project.

  1. http://pttimeselect.sourceforge.net/example/ (I think this is the cleanest, and works the best next to the date picker, because it looks the same. though it’s not the fastest or most efficient, but I think it’s the most developed.)
  2. http://milesich.com/tpdemo/ (ok but a little overwhelming possibly to some people because of the + the done button that needs to be pressed)
  3. http://labs.perifer.se/timedatepicker/ (this is probably the simplest option, but like I said, 100 might be a pain for some users)
  4. http://haineault.com/media/jquery/ui-timepickr/page/ (while my wife used it fine on the first try, it wasn’t scientific because I didn’t give her a specific time to set.)
  5. http://www.jnathanson.com/index.cfm?page=jquery/clockpick/ClockPick (OK but a little less intuitive than timepickr)
  6. http://www.radoslavdimov.com/jquery-plugins/jquery-plugin-timepicker/ (kinda ok, like a time only version of the second option, but sideways, I’m not sure how well AM/PM works because there isn’t an example)
  7. http://keith-wood.name/timeEntry.html (neat but totally hard to use until you realize its keyboard-arrow-key driven, oops I gave it away)

I think my dream selector would actually be more like this most excellent timer widget for OS X that I use almost every day called Minutes. You’d just grab it and spin around until you have the time you want, then let go to set. Anyway when I have a project with a better budget then I’ll maybe make that version…

SWFAddress, if You Aren’t Using it for All Your Flash, Start to

Posted in Flash AS 3.0, Flex 3, javascript | Friday, April 3rd, 2009 | No Comments »

We’ve been using SWFAddress for a while now, and while I was cleaning old project files out of Flex I came across my first Flex Test using it. It’s simple, and in fact, SWFAddress has been improved a bunch since this test was made (mostly involving SEO, and fallback links + Google Analytics). Now we’re using it for running our entire navigation schemes for all Flash sites, mini-sites, components, and even in our pitches.

Check out my example (click anywhere to move the box, then use the back/forward buttons for undo/redo).

Prototype javascript css Tabs

Posted in javascript, prototype, tabs | Saturday, December 29th, 2007 | No Comments »

Recently I had to make tabs. Something that has been solved hundreds of times. However I didn’t want to fuck around with a special user interface framework like http://developer.yahoo.com/yui/. Since I use prototype on almost every project since its inception, I decided to just roll out my own solution using the prototype library as a base. It turns out that the implementation was incredibly simple. I have attached a working example for your copy and paste pleasure. The javascript is incredibly simple. The entire javascript programming was less than 25 lines.

Google maps state zoom and center code

Posted in api, google, javascript, maps | Monday, December 17th, 2007 | 3 Comments »

This is exactly what you would think it is. I fucked around with getting these bounding values so you don’t have to. I think you will find this useful if a client says to you, “now how do I jump to a state”. You will need the prototype library for this to work. I use it for element selection. If you know how to get the element in other ways then you likely don’t need me to tell you how to change this code. If you would like to download prototype click here.

make sure you include the prototype library before the code for you map.

First the select box that you will need somewhere on your UI

The javascript you no doubt need, is the zoom to state code. It is basically a large switch statement with sensible latitudes and longitudes for zooming and centering. So here it is
