Solved my own problem and thought I would share it here for those who
may run into the same problem as I.
When you need to apply a method (such as the selectedIndex and value
setting I tried) across multiple elements, you have to use the
invoke() method. in my case I had to use the following statements:
First, I decided that I needed to clear the options from my other
select boxes instead of just selecting the top one, so I used...
$("selectTwo","selectThree","selectFour").invoke("update","<option
value='0'>none</option>");
Form my text/hidden fields, I used this...
$("warrantyAmount","hWarrantyType","hWarrantyCost").invoke("setValue",
"0.00");
Which BTW uses the undocumented setValue() method. I was about to add
this method myself when I found that it already existed! Why such an
important and useful method is not in the documentation I will never
know.
