i have javascript that validate every user input and only allow character to be inputed in input text.

my issue is im using input text with no submit button (search form). my javascript doesn't allow hotkey enter, here my code :

function getkey(e)
{
if (window.event)
   return window.event.keyCode;
else if (e)
   return e.which;
else
   return null;
}
function angkadanhuruf(e, goods, field)
{
var angka, karakterangka;
angka = getkey(e);
if (angka == null) return true;
 
karakterangka = String.fromCharCode(angka);
karakterangka = karakterangka.toLowerCase();
goods = goods.toLowerCase();
 
// check goodkeys
if (goods.indexOf(karakterangka) != -1)
    return true;
// control angka
if ( angka==null || angka==0 || angka==8 || angka==9 || angka==27 )
   return true;
    
if (angka == 13) {
    var i;
    for (i = 0; i < field.form.elements.length; i++)
        if (field == field.form.elements[i])
            break;
    i = (i + 1) % field.form.elements.length;
    field.form.elements[i].focus();
    return false;
    };
// else return false
return false;
}
<div class="search-box" style="margin-top: 20px;">
            <form method="POST" id="searchform" action="search.html" >
          <input name="kata" type="text" placeholder=" "  onKeyPress="return angkadanhuruf(event,'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789@.-_',this)"/>

          </form>
            </div>
