    <input type="email" class="form-control" id="exampleInputEmail1" aria-describedby="emailHelp" placeholder="Enter email">
    <small id="emailHelp" class="form-text text-muted">We'll never share your email with anyone else.</small>

</form>

2. jQuery Validation Plugin

代码示例：

$(function(){
  $("#myForm").validate({
    rules: {
      email: "required",
      password: {
        required: true,
        minlength: 5
      },

      }
    },
    messages: {

    }
  });
});

  );
}

export default MyForm;
