Specify minimum and maximum values
This option is only available for the "integer", "date", "time", "currency", and "real" validation types.
To specify minimum or maximum values in the text
field, add the minValue property or maxValue property
(or both) and a value to the constructor, as follows:
<script type="text/javascript">
var tf1 = new Spry.Widget.ValidationTextField("textfieldwidget1", "validation_type", {minValue:value, maxValue:value});
</script>
