Expand | Embed | Plain Text

Copy this code and paste it in your HTML

The javascript allows only number and decimal points:
 
<SCRIPT language=Javascript>
       <!--
       function isNumberKey(evt)
       {
          var charCode = (evt.which) ? evt.which : event.keyCode;
          if (charCode != 46 && charCode > 31 
            && (charCode < 48 || charCode > 57))
             return false;
 
          return true;
       }
       //-->
    </SCRIPT>
 
The blank amount to pay field displays the $ until the field is active:
 
 <input type="num" name="charge_total" value="$" onfocus="this.value=''" onkeypress="return isNumberKey(event)" >
