Re: Navigating JSON sub-arrays dynamically

There are several methods of doing this. For MVC the standard seems to be
using jQuery and JSON. For the "standard" method, it can be done a few more
ways. In fact, I am sure there is a better way than I am doing this, but
this works and it is quite quick. When I get some time, I can put together
an example in MVC to see what I did. Real slick!

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) {
