İşin içinden çıkamadığım bir sorun. Yapabilecek arkadaş var mı acaba
Şifre1 ve tekrar şifrenizi yazın alanlarına rakamları javascript keypad kullanarak girdirmek istiyorum.
Lakin jquery kullanmak istemiyorum.

<form action="" method="post" class="" name="numPad">
<table cellpadding="2" cellspacing="2" border="0" width="44">
<tr>
     <td colspan="3" align="center">
		<p align="right">Şifreniz<input type="text" name="quantity" size="10"></td>
</tr>
<tr>
     <td colspan="3" align="center">
		<p align="right">Şifre2<input type="text" name="quantity1" size="10"></td>
</tr>
<tr>
     <td><input type="button" value="  1  " onclick = "document.numPad.quantity.value =document.numPad.quantity.value+ this.value"></td>
     <td><input type="Button" value="  2  "  onclick = "document.numPad.quantity.value =document.numPad.quantity.value+ this.value"></td>
     <td><input type="Button" value="  3  "  onclick = "document.numPad.quantity.value =document.numPad.quantity.value+ this.value"></td>
</tr>
<tr>
     <td><input type="Button" value="  4  "  onclick = "document.numPad.quantity.value =document.numPad.quantity.value+ this.value"></td>
     <td><input type="Button" value="  5  "  onclick = "document.numPad.quantity.value =document.numPad.quantity.value+ this.value"></td>
     <td><input type="Button" value="  6  "  onclick = "document.numPad.quantity.value =document.numPad.quantity.value+ this.value"></td>
</tr>
<tr>
     <td><input type="Button" value="  7  "  onclick = "document.numPad.quantity.value =document.numPad.quantity.value+ this.value"></td>
     <td><input type="Button" value="  8  "  onclick = "document.numPad.quantity.value =document.numPad.quantity.value+ this.value"></td>
     <td><input type="Button" value="  9  "  onclick = "document.numPad.quantity.value =document.numPad.quantity.value+ this.value"></td>
</tr>
<tr>
     <td colspan="3">
		<p align="center">
		<input type="button" value="       0         "  onclick = "document.numPad.quantity.value =document.numPad.quantity.value+ this.value"></td>
</tr>
</table>
</form>
