How to param in setParameter for an array

Hello,
I have a requirement to get the group of text in an array and set the parameter for each text, so that these parameters will be read by a perl script to update onto the database.

But from the following code, I could not get the param values in my perl script from my javascript/ajax.

for(k = 0; k<site.length; k++){
r.setParameter('site_desk+k', desk_det[k].getControlText());
}

Can anyone please help me, if I am missing something?

Thanks in advance

Sorry, please ignore the above post, I solved the above issue.

Thanks
Vijay
