More than one decimal point

[Matt]

Greetings,

I am trying to figure out which input control to use.  We have numeric account numbers that can have zero to many decimal points.  For example...

123456
123.456
12.345.6789
1234.5.6

These would all be valid account numbers.  I need to have an input that only allows numbers and periods.  Any advice?

Much appreciated,

Matt

Never mind, I found the documentation about OnKeyPress. Here is what I used...

<script type="text/javascript">
    function NumericPeriodOnly(sender, eventArgs) {
      var c = eventArgs.get_keyCode();
      if ((c < 48 || c > 57) && c !== 46)
        eventArgs.set_cancel(true);
    }
  </script>
