paypal options required field

I'm using Paypal with some Option fields like below:

    <input type="hidden" name="on0" value="note" />
<input type="text" name="os0" />

Is it possible to make this a required field? I know Paypal has it's own required fields to be passed.

Many thanks

Solution

  • You could just do:

    <input type="text" name="os0" required />

    HTML5 takes care of the validation for you.

    But support is not guaranteed: http://caniuse.com/forms

    A better solution would be to use something like the jQuery Validate plugin.
