Here is some expectablel solution not sure...
for example , if you have a quantity field then , if we entered any letters on that it will show an immediate alert "Please Enter Only Numbers (0-9)"
if this is your expected solution . then the following is the code for that...if not post clearly....

<form name="exampleform" method="post" action="">
<input name="qty" type="text"  id="qty" value="" onKeyUp="Only_Num(this.id)" size="3" maxlength="5">
</form>

function:

function Only_Num(id)
{
 if(isNaN(document.getElementById(id).value))
 {
  alert("Please Enter Only Numbers (0-9)..");
  document.getElementById(id).value='';
  document.getElementById(id).focus();
 }
 return;
}
