ajax/javascript blocked ?

hi all,

I have a site running where ppl can add their events into a database.
when they choose a country from a listbox, a second listbox (province gets filled with options depending on the choise in the first.)

This is doen through ajax/javascript.
all works well but on some pcs (5%) it does not fill the second listbox with the options.
As far as I have been able to determin it is always on a pc at work of the user.
So I guess some of the functionalities of ajax/javascript are blocked.
Am I correct in assuming this?

attatched the code snippet of the main page and the help page that is called to display the second listbox.

if JavaScript is disabled, AJAX will not work either.

re: ajax/javascript blocked ?

that I know,

But the problem is that I cannot check the settings of my surfers.
Is there a way to check if they have the correct settings?
and if they have not, automattically show an alert on the page of my site?

re: ajax/javascript blocked ?

you can't show an alert-that would require JavaScript enabled-but you can leave a note. either via <noscript> or via a html (text) element that is deleted if JavaScript is enabled.

you could also make a fallback with a form instead of AJAX (forms do not depend on JS)

tnx,

I'll make a noscript message then.
And see if the ones with the problem see that message.

greetings
