View Full Version : count related input values!

12-09-2004, 03:35 PM
I need to write a javascript function. There are two fields "Number of Items" and "Item ID". "Item ID" has 5 input fields. If the field "Number of Items" is chosen as 1, then "Item ID" needs 1 Id input. If the "Number of Items" is 2, 2 ID inputs are needed and so on. Could anybody help me in writing this function please. Thanks in advance.

Hi A1ien51,

Thanks for the code but it is not working :-(

It is not so difficult, but before answering, I would like to know... But if the user inputs 6? or a letter? Wouldn't it be easier to use a select with preset options values?

By the way, I guess you forgot to specify the type of the input elements. I presumed that they are all type="text"
