value

Specifies the value of the MaskedTextBox widget. Overrides the value attribute of the underlying INPUT element if set.

The code below demonstrates how to specify a value option.

<input id="maskedtextbox" />
<script type="text/javascript">

jQuery(function($) {
       $("#maskedtextbox").shieldMaskedTextBox({
             mask: "(000) 000-000",
             value: "(889) 333-666"
       });
});
</script>
