Re: Navigating JSON sub-arrays dynamically

Couldn't you use something like selectCombo for jQuery v 1.2.3
(combo.js) plus populate.js. Combo.js handles the combo and when you
make a selection populate fills in the fields on your page.

Or maybe there is something unique in your implementation that I am
missing.

Hi Mike,

Does ASP/.net provide a reusable component to handle this "parent/child"
drop down list challenge or do you have to code for each occurance?
This "parent/child" pattern is common in a lot of business apps we run
into. (IE Select a car mfg such as Ford or GM, then based on the
parent, show the models (F150, Explorer)

Thanks, Paul

The

problem with Kevin's solution is that the IDs will not be sequential or

they

can change.

From there these are the two lines that work:

var i = findIndexByKeyValue(jsonRequestType, "Id", key);
$.each(jsonRequestType[i].HourTypeCodes, function(i, item) {
