Hi
I am using the following script's attached  to format decimal places and pad zeros.
Is there a way to combine both pieces of code. At present one will undo the other
What I need is if I enter 8 ,  On Change  It becomes 008.0000 or if I enter 89.9  On Change it becomes
089.9000


Decimal places          onchange="fix(this)" 
function fix(o){
 if( !isNaN(parseInt(o.value,10)) )
 {
    o.value = parseInt(o.value).toFixed(4);
 }
}
 
Pad zeros     onblur="padValue(this,3);"
function pad(num, count) {
 
var lenDiff = count - String(num).length;
 
var padding = "";
 
 
if (lenDiff > 0)
 
while (lenDiff--)
 
padding += "0";
 
 
return padding + num;
 
}
 
 
function padValue(el, count) {
 
var num = Number(el.value);
 
 
if ( isNaN(num) ) {
 
alert("Please only enter numbers");
 
} else {
 
el.value = pad(num, count);
 
}

Use the following function like this:

onblur="formatField(this,4,8);"
function formatField(obj, decimals, len) {
   var n = Number(obj.value);
   if (!isNaN(n)) {
      var s = parseInt(n).toFixed(decimals);
      while (s.length < len) s = '0' + s;
      obj.value = s;
   } else {
      alert("Please only enter numbers");
   }
}
