Sorry, that should have read "can't":
which is basically my example. You CAN'T have elements in an array
like
this:
[ "department": {"ID": 1, "Name": "Physics"} ]

This:
var departments = new Array();
var department = {};
department.ID = 1;
department.Name = "Physics";
deparments.push(department);
is not a non-shorthand version of this:
{ "departments": [
"department": {"ID": 1, "Name": "Physics"},
"department": {"ID": 2, "Name": "Chemistry"},
"dep

Talking about my first post?
I'm not so sure the JSON you posted
{ "departments": {
"department": {"ID": 1, "Name": "Physics"},
"department": {"ID": 2, "Name": "Chemistry"},
"department": {"ID": 3, "Name": "Biology"}
}}
is valid, as Steven points out, the last "department" wins e
You can't put 'bare' key/value pairs in an array, and reusing a key
like department isn't really good either. A simpler structure would
just be:
[ {"ID": 1, "Name": "Physics"}, {"ID": 2, "Name": "Chemistry"},
{"ID": 3, "Name": "Biology"} ]
Unless you have some compelling reason to assign the arr
ok so it works.
so for my understanding, the parameters department refers to the index
(0, 1, 2) and dictionary refers to the json object that i can use
something like dictionary.ID on

Actually.. looking @ that JSON again after Steven's post, the JSON
should be
{ "departments": [
"department": {"ID": 1, "Name": "Physics"},
"department": {"ID": 2, "Name": "Chemistry"},
"department": {"ID": 3, "Name": "Biology"}
]
}
Pretty sure anyways... it's been a long day :-)
O
I think the problem is you have the "department" 3 times in the same hash
object,so the last one overrides everything.
you should change "departments" to an array and loop through it

$.each(json.departments, function(department, dictionary) {
alert("ID: " + dictionary.ID + "\nName: " + dictionary.Name);
});

thanks all. but what about the default "Please select a value" option?
how can i have it such that the user either
- cannot select that option - shown only on 1st run
- can select the option but will cause the 2nd dropdown to empty -
dunno if this is good idea
or any other suggestions ?
btw, as
I've not tried Eric's plugin, but if converting the JSON is an issue,
you can use what you have (but be sure and quote the string values;
preferably the keys too even though most people don't):
[
{Value: 1, Item: 'Physics'},
{Value: 2, Item: 'Chemistry'},
{Value: 3, Item: 'Biology'}
];
Here's the
Ice, I just recently released a plugin that might suit your needs.
It's basically a way to transmit HTML as JSON for this exact kind of
thing.
Check out: code.google.com/p/hsjn
Taking the case you gave, if you change the JSON your returning to:
[['option', {value: 1}, 'Physics'],['option', {val
