jQuery表单验证和提交问题 - jQuery Form validation and submission issue

我有下面的表单，它使用jQuery来验证表单，并在所有字段都填写正确的情况下提交。到目前为止一切都很好。但我想添加以下内容，但不知道如何添加（因为我是jQuery的新手）。

文本框（如名字和姓氏）不应接受任何数字

如何将这些添加到我的代码中？请帮忙。

这是我的密码。

<?php
include'includes/db.php';
if(isset($_POST['submit']))
{ 
     $fname =(!empty($_POST['firstname']))?$_POST['firstname']:null;
     $lname =(!empty($_POST['lastname']))?$_POST['lastname']:null;
     $email =(!empty($_POST['email']))?$_POST['email']:null;
     $mobile =(!empty($_POST['mobile']))?$_POST['mobile']:null;
     $dob =(!empty($_POST['dob']))?$_POST['dob']:null;
     $location =(!empty($_POST['location']))?$_POST['location']:null;
     $state =(!empty($_POST['state']))?$_POST['state']:null;
     $gender =(!empty($_POST['gender']))?$_POST['gender']:null;
     $str = "INSERT INTO members(mem_fname, mem_lname, mem_email, mem_mobile, mem_dob, mem_location, mem_state, mem_gender)VALUES('$fname', '$lname', '$email', '$mobile', '$dob', '$location', '$state', '$gender')";
     $sql = mysql_query($str);
     if($sql){
     echo "Data Inserted Successfully";
     }else{
     echo "Data insertion failed";
     }
}
?>

您可以使用jquery validate 的additional-method.js文件中的模式规则

$("#register-form").validate({
    rules: {
        firstname: "required",
        lastname: "required",
        email: {
            required: true,
            email: true
        },
        mobile: {
            required: true,
            minlength: 10,
            pattern: /^[789]/
        },
        dob: "required",
        location: "required",
        state: "required",
        gender: "required",
        agree: "required"
    },
    messages: {
        firstname: "Please enter your first name",
        lastname: "Please enter your last name",
        mobile: {
            required: "Please provide your mobile number",
            minlength: "Your mobile number must be 10 characters long",
            pattern: 'should start with 7,8 or 9'
        },
        email: "Please enter a valid email address",
        dob: "Please provide you Date of Birth",
        location: "Please provide your location",
        state: "Please provide your state",
        gender: "Please provide your gender",
        agree: "Please accept our terms of service"
    },
    submitHandler: function (form) {
        form.submit();
    }
});

演示：Fiddle

您需要添加像以下这样的新方法：

jQuery.validator.addMethod("checkMobileNumberFirst", function(value, element) {
    firstNumber = value.substring(0,1);
    if (firstNumber <= 9 && firstNumber >=7  ){
        return true;
    }else{
        return false;
    }
}, "The Mobile phone number has to start with 7, 8 or 9");

然后在验证中添加新方法：

        mobile: {
            required: true,
            minlength: 10,      
            checkMobileNumberFirst: true
          },
