验证 10 位手机号码并将输入字段焦点设置为无效

我需要在 jQuery 中验证电子邮件和手机号码的代码focus()在验证不满足的特定领域。

这是我的查询

<form name="enquiry_form" method="post" id="enquiry_form">

    Full Name *
    <input class="input-style" name="name"  id="name" type="text" required> 
    Email *
    <input class="input-style" name="email"  id="email" type="email" required>
    Phone * 
    <input name="mobile"  id="mobile" type="number" required>

    <input type="submit" value="SUBMIT"  id="enq_submit"">

</form>

上面的代码是正确的，但移动验证并不完美。

我修改为

$('#enquiry_form').validate({
  rules:{
  name:"required",
  email:{
  required:true,
  email:true
  },
  mobile:{
      required:true,
  minlength:9,
  maxlength:10,
  number: true
  },
  messages:{
  name:"Please enter your username..!",
  email:"Please enter your email..!",
      mobile:"Enter your mobile no"
  },
  submitHandler: function(form) {alert("working");
  //write your success code here  
  }
  });
