From there these are the two lines that work:

As I mentioned before, since there is no way to directly reference object
that contains the HourTypeCodes you have to make the assumption that the
value form your first drop down box is always going to be relevant to its
array index.
In other words, you would have to replace this:
$.each(jsonRequestType.Id[key].HourTypeCodes, function(i, item) {
With this
$.each(jsonRequestType[parseInt(key)-1].HourTypeCodes, function(i, item) {

Subject: Re: [WEB400] Navigating JSON sub-arrays dynamically
People have been talking about jQuery/javascript frameworks on here, I
figured I would ask. This does connect to the iSeries being used as a DB so
it is sort of related. Here is the relavant parts:
$(document).ready(function() {
var jsonRequestType;
var jsonRequestTypeRecieved = false;
$.getJSON('/WebService/GetRequestInformation', function(json) {
jsonRequestType = json;
jsonRequestTypeRecieved = true;
});
// Get the request types for the drop down
$(".RequestTypeDdl").live("focus", function() {
var items = "<option>(Select)</option>";
var field = $(this);
var savedParent = 0;
$.each(jsonRequestType, function(i, item) {
if ((savedParent != item.ParentId) && (savedParent != 0))
items += "</optgroup>";
if (item.ChildRequired)
items += "<optgroup label='" + item.Title + "'>";
else {
items += "<option value='" + item.Id + "'";
if ($(field).prev("input").val() == item.Id)
items += " selected";
items += ">" + item.Title + "</option>";
};
});
$(this).html(items);
});
// Stored the selected value so it isn't lost
$(".RequestTypeDdl").live("change", function() {
// Stored the selected value so it isn't lost
$(this).prev("input").val($(this).val());
// Build the second DDL
var key = $(this).prev("input").val();
var tsddl =
$(this).parent("td").next("td").children(".TimesheetCodeDdl");
var items = "<option>(Select)</option>";
var savedParent = 0;
$.each(jsonRequestType.Id[key].HourTypeCodes, function(i, item) {
if ((savedParent != item.ParentId) && (savedParent != 0))
items += "</optgroup>";
if (item.ChildRequired)
items += "<optgroup label='" + item.Title + "'>";
else {
items += "<option value='" + item.Id + "'";
if ($(tsddl).prev("input").val() == item.Id)
items += " selected";
items += ">" + item.Title + "</option>";
};
});
$(tsddl).html(items);
});
});
Here is a valid section of my JSON:
[{
"Id": 1,
"Title": "Vacation",
"HourTypeCodes": [
{
"Id": "05",
"Title": "VAC POLICE/FIRE"
},
{
"Id": "04",
"Title": "VACATION"
},
{
"Id": "62",
"Title": "VACATION HOURS PURCHASED"
},
{
"Id": "60",
"Title": "VACATION SELL BACK"
}
]
},
{
"Id": 2,
"Title": "Holiday",
"HourTypeCodes": [
{
"Id": "08",
"Title": "HOLIDAY"
}
]
},
{
"Id": 3,
"Title": "Floating Holiday",
"HourTypeCodes": [
{
"Id": "09",
"Title": "FLOATING HOLIDAY"
}
]
}]

Strange forum for a JSON/jQuery question - but anyhow, the JSON you haveOn
posted is syntactically incorrect. Is that just a typo?
Can you post all the significant code please, rather than a snippet, and
explain a bit more fully what you are trying to do.
Thanks

Subject: [WEB400] Navigating JSON sub-arrays dynamically
I am using JSON and jQuery to dynamically populate a parent/child
lists. I have it working to fill the parent drop down and have the childsub
drop down filling with the same parent data. How do I loop through the
array of the selected value from the parent?POLICE/FIRE",},{"Id":"04","Title":"VACATION"},{"Id":"62","Title":"VACATION
My "each" line (key is the value from my parent DDL:
var key = $(this).prev("input").val();
$.each(jsondata.Id[key].HourTypeCodes, function(i, item) {
My JSON
[{"Id":1,"Title":"Vacation","HourTypeCodes":[{"Id":"05","Title":"VAC
HOURS PURCHASED"},{"Id":"60","Title":"VACATION SELL BACK"}]},{"Id":2,"Title":"Holiday""HourTypeCodes":[{"Id":"08","Title":"HOLIDAY"}]},
{"Id":3,"Title":"Floatingby
Holiday","HourTypeCodes":[{"Id":"09","Title":"FLOATING HOLIDAY"]}]
What am I doing wrong?
