I'm a bit confused here. Do you want to delete values from the database or do you want to clear options from a select box?

sorry to make u confused sir, i want to clear the options from the select box. not from database.

Well the general rule is if you have a select by the name box, then

To clear all options of box just do
box.options.length = 0;

box.options.length = 0;

This is by far the best way to remove the options. If you try to remove them one by one in a loop you won't be able to remove the last option. I lost a good bit of hair before realizing that options.length=0; is all I needed :/

I hope the hair grew back on.
