mask for one digit and two digit

问题

I have been using this $("#SomeId").mask("99"); jquery mask for text box where I want to enter only two digit numbers, but i do not know which mask to put in order to enable entering only one digit number and two digit. From 0-99

with mask above I cannot enter one digit number, the text box become blank when it lose focus.

回答1:

{mask: 9, 'maxLength': 2} should work

Edit: you have not specified what mask have you used; my answer is related to meioMask plugin.

Edit 2: for maskedinput 1.2.2:

$("#SomeId").mask("9?9");

<html>

        <script type="text/javascript">
            $(document).ready(function(){
                $('#test').keypress(allowOnlyTwoPositiveDigts);
            });

            function allowOnlyTwoPositiveDigts(e){

                var test = /^[\-]?[0-9]{1,2}?$/
                return test.test(this.value+String.fromCharCode(e.which))
            }

        </script>
    </head>
    <body>
        <input id="test" type="text" />

<input id="id_input" class=".class_input" type="text" />

$('#id_input').mask('99');
$('.class_input').mask('99');
