@Mike
Hi again!
I'm "almost" getting it. I guess what I'm trying to do is use nested
arrays within the JSON structure and maybe jQuery can't handle it?
I've restructured the JSON file to be:
{
"Country1": {
"Region1": [
"Citya1",
"Citya2",
"Citya3"
],
"Region2": [
"Cityb1",
"Cityb2",
"Cityb3"
]
}
}
It's basically a nested array. I'm trying to get the (chained)
cascade plugin to simply read in the text on each first level of the
array (ie. the second dropdown box will be populated with all the
"Region#" in the array since the match found in the selectedValue
would equal "Country1".
Then the same function should automatically populate the 3rd dropdown
will the related City# -> ie. if Region1 is selected (as would be the
default in this case), the third dropdown would be populated with all
the Citya# texts.
Does this make sense?
Am what I am trying to do even possible with jQuery's handling of
JSON?
Firebug does tell me that the object has been read correctly and is an
array structure Country1.Region1.City1 (etc)...
If you could point me to just a little more help I think I can get
this! :)
Thanks,
James
