Si I know the feeling. I have so many personal projects half finished, books half read, magazines not even looked at. Client work seems to be taking over my life right now, and when it isn't all I want to do is escape the house (where I reside 24 hours a day most of the time!).

But yes, the book, so far, has been great

Hi Sarah,
I have to admit I have finished the book either due to opensource project commitments, real life and normal work. Am glad you're enjoying the book though.

Finally got the form to work using submit() and a bit of trickery. I'll write up about it in the morning. I have an admin section to finish first!

Cheers to Sam and Marc for their input

Update – looks like onsubmit and return false don't play well together as it works fine if I use the click() function. Now I just have to work out how to do it all dynamically!

Marc my apologies. I've just worked out what the problem was after comparing your code to mine. The first option in my parent list has

and that's what was coming up as undefined and subsequently killing the function.

Your code does indeed work perfectly. I can't believe I've just lost the entire morning to an empty value!

Thank you so much for the code. I'd have never worked it out otherwise!

The first code works, I tested it.. which is a solution based on exactly how you described what you wanted to do it. Here is the full paste: Reset Select Lists based on Select with Ids

If you want to get the prefix selector working then make a button with id="reset" then run this code:
$("#reset").click(function(){ $('select[id^=child]').each(function(i,select){ $(select)[0].selectedIndex = 0; }); });

On #2, if return false isn't working then an error occurred in your code. Watch firebug carefully as you submit the form.

Have you tried:

$("select[id*=child]").selectedIndex = 0;

Sam, I tried it without too. It didn't do anything at that point.

take out the [0] which is limiting your results to the first one

Change that, the one liner fix for point 1 only does the first select list not all 6

Back to trying to get the each function to work.
