Question

只是对空字段进行jquery验证，jquery验证字符数和jquery验证数值不起作用。

        number: true,
        minlength:7
        },
        nombre:{
        required: true,
        minlength:3
        },
        apellido:{
        required: true,
        minlength:4
        },

        });

        </script>            
        </head>
        <body>
            <h1>Crear una Persona</h1>
            <form id="createPersonForm" action="crearPersona.do" method="post">
        <div class="navbar navbar-fixed-center">
        <table>
        <tr><td>Rut:</td><td><input type="text" id="rut" name="rut"    required/><span id="dato1"></span></td></tr>

        <tr><td>Nombre:</td><td><input type="text" id="nombre" name="nombre" required/><span id="dato2"></span></td></tr>

        <tr><td>Apellidos:</td><td><input type="text" id="apellido" name="apellido" required/><span id="dato3"></span></td></tr>

        </table>
        <div class="navbar-inner">  
        <br/>    
        <input type="submit" class="btn btn-info" id="CrearRegistro"   value="CrearRegistro" />
        </div>
</div>
        </form>
        </html>

输入小于最小数量的数量时，不进行任何验证。当你输入字母接受它们时，只接受车辙中的数字。

您的验证功能中有一些缺失的括号，您也缺少submitHandler。请验证以下是一个工作示例。希望这有帮助。
