| Post subject: | Javascript Validation On Multiple Select Lists |
Hi, I have a multi select box with about 100 optoins. I need to make sure the user selects at least one, but no more than three options. I need a javascript function to validate this behaviour on: <select multiple name="category_id" size="10"> ...<options> </select> |
