Since I get so much great info and help from the
lists I'm on, every now and then I like to try and
give something back.
I just finished some code that is pretty useful
for populating one drop down based on the
selection of a previous one, so I thought I'd pass
it along in case anyone found it useful. I'm sure
many of you already have a way to do this in your
toolbox, but thought some may not.
I've seen many examples of doing this Googling
around, but found them overly complex, and I think
I've come up with a quite simple and affective way
to do it with not too much code.
Basically, I had a need to populate a dropdown
containing areas within the boroughs of New York
City based on which borough was selected. So say
they select Manhattan in the first dropdown, the
second dropdown then becomes populated with the
areas within Manhatan.
The code builds the possible arrays for the
second dropdown from the database when the page
loads, then plugs them directly into the JS,
making the whole arrangement dynamic. Change the
DB and the dropdown adjusts accordingly.
If you'd like to see the code email me off list
and I'll pass it along.
