I was helping someone today with their javascript and they asked me about how and when I manage errors in the classes and functions that I write. I wrote him back an email which I think actually could be useful to others, so here it is.
There are three types of error handling that I use:
- Graceful: if possible, just ignore the error and continue with some default state or without a meaningful value
- Debug: throw a warning to the dbug.log method but continue otherwise
- Break: Either explicitly throw an error or (more often) just let the error that is thrown at runtime be thrown

New date picker, Date extentions, Auto-ajax indicator, and Input text hovers
So I just finished pushing out and testing my latest batch of additions to the CNET Libraries and you can download them in our svn. Here’s a brief roundup with links to demos and stuff:
- DatePicker got a lot of love including the ability to output a custom format for the date and the ability to choose ranges and enter times
- Extended the Native Date object to add lots and lots of neat-o methods including date comparison, fancy parsing, and about 2 dozen other useful features and methods
- OverText – a new Class that hovers text over inputs until the user clicks into them and changes them
- Waiter – an ajax indicator class that automatically greys out a dom element with a spinner image (you can customize these things) while your Ajax is requesting new HTML for it. Can be used stand alone (i.e. if you need to show a waiting indicator even if it’s not Ajax you’re using), but it’s integrated nicely into Ajax if you are using it.
- Our default DHTML popup html (stickyWinHTML) got an option to add a drag handle to the window
The Waiter class is probably my favorite, but all the Date love is really nice, too. Check it out and play around with it.
