Idevices makes the 1st letter capital solution [vouchers]

itson

my vouchers are all lower case letters & numbers only.
all idevices makes the 1st letter capital,
need a solution with the index page and input box to accept only lowercase letters.
im having really hard time trying to figure this out, please help here is my current index.html


<form method="post" action="$PORTAL_ACTION$" onsubmit="return CheckBoxesValidations() ;"> 

  <title>BlaBla</title>

# Please Log-in to use WiFi

<center>
Accept</center>

</form>

itson

my idea was this
include a call to "myFunction()"


<form method="post" action="$PORTAL_ACTION$" onsubmit="return CheckBoxesValidations() &amp; myFunction();"> 

remove the name="auth_voucher" from input box and give it id

and at the bottom i have the myFunction taking the useriput from the inputbox and converting it to lowercase and then putting it in "auth_voucher"

will this work? 

will the method=post take the auth_voucher variable from java? 

please help !! </form>
