我在网络上尝试了多种解决方案，例如

下面提供了我的主要代码:

My main code is provided below:

jQuery

$('.login-form').validate ({
        // validation rules for registration form
    errorClass: "error-class",
    validClass: "valid-class",  
    onError : function(){
        $('.input-group.error-class').find('.help-block.form-error').each(function() {
          $(this).closest('.form-group').addClass('error-class').append($(this));
        });
    },

        rules: {
            username: {
                required: true,
                minlength: 3,
                maxlength: 40
            },

          password: {
                required: true,
                minlength: 7,
                maxlength: 20
            }
            },

        messages: {
            username: {
                required: "Please enter your username or email address",
                minlength: "Usernames can't be shorter than three characters",
                maxlength: "Usernames or emails must be shorter than forty characters."
            },
                       password: {
                required: "Please enter your password",
                minlength: "Passwords can't be shorter than seven characters",
                maxlength: "Passwords must be shorter than forty characters."
            },

                highlight: function(element, errorClass) {
        $(element).removeClass(errorClass);
    }    
        },

  submitHandler: function() {  
            $('#noenter').show();   

        }  
    });

    errorClass: "error-class",
    validClass: "valid-class",
    errorElement: 'div',
    errorPlacement: function(error, element) {
        if(element.parent('.input-group').length) {
            error.insertAfter(element.parent());
        } else {
            error.insertAfter(element);
        }
    },
    onError : function(){
        $('.input-group.error-class').find('.help-block.form-error').each(function() {
          $(this).closest('.form-group').addClass('error-class').append($(this));
        });
    },

        rules: {
            username: {

                highlight: function(element, errorClass) {
        $(element).removeClass(errorClass);
    }
