Question

我正在使用jQuery Validation插件。

如何将成功类添加到另一个元素？

如果我输入正确的电子邮件地址，我想为div.field分配一个类 - 这是否可以使用jQuery Validation插件？

HTML：

<form id="registration" method="get">
    <fieldset>
        <legend>Registration Details</legend>
        <div class="field">
            <label for="email">Email<em>*</em>

            </label>
            <input type="text" name="email" id="email" class="required email" />
        </div>
        <div class="field">
            <label for="confirm_email">Confirm email<em>*</em>

            </label>
            <input type="text" name="confirm_email" id="confirm_email" class="required email" />
        </div>
        <div class="password">
            <div class="field">
                <label for="password">Password<em>*</em>

                </label>
                <input type="password" name="password" id="password" class="required password min-length_6" />
            </div>
            <div class="field">
                <label for="confirm_password">Confirm<em>*</em>

                </label>
                <input type="password" name="confirm_password" id="confirm_password" class="confirmation-of_password" title="Please enter the exact same password" />
            </div>
        </div>
    </fieldset>

JavaScript的：

var formActions = {};


// Form initialisation
formActions.init = function () {
    // Validate For Registration
    $('#registration').validate({
        rules: {
            email: "required",
            confirm_email: {
                required: true,

                email: true
            },
            password: {
                required: true,
                minlength: 5
            },
            confirm_password: {
                required: true,
                minlength: 5,
                equalTo: "#password"
            }
        },
        messages: {
            email: {
                required: "Please enter a valid email address."
            },
            confirm_email: {
                required: "Please enter a valid email address.",


            },
            password: {
                required: "Please provide a password",
                minlength: "Your password must be at least 5 characters long"
            },
            confirm_password: {
                required: "Please provide a password",
                minlength: "Your password must be at least 5 characters long",
                equalTo: "Please enter the same password as above"
            }
        }
    });

};

$(formActions.init);

Answer 1

您只需修改默认的highlight和unhighlight回调函数即可。您只能修改 not remove 这两个回调函数，否则添加/删除标准错误/有效类的正常行为将被破坏。

我使用了默认的回调函数来保留它们的正常行为，并添加了以下一行，它将定位父div并应用类.newclass。我只是为这个class指定了一个绿色背景颜色，只是为了证明它在jsFiddle中工作。您可以根据需要重命名和重新设置此class。

$(element).parent('div.field').addClass('newclass');

DEMO：http://jsfiddle.net/C7eWy/

将这些修改过的回调函数添加到.validate()：

中

    highlight: function (element, errorClass, validClass) {
        if ($(element).attr("type") === "radio") {
            this.findByName(element.name).addClass(errorClass).removeClass(validClass);
        } else {
            $(element).addClass(errorClass).removeClass(validClass);
            $(element).parent('div.field').removeClass('newclass'); // <-- added this line
        }
    },
    unhighlight: function (element, errorClass, validClass) {
        if ($(element).attr("type") === "radio") {
            this.findByName(element.name).removeClass(errorClass).addClass(validClass);
        } else {
            $(element).removeClass(errorClass).addClass(validClass);
            $(element).parent('div.field').addClass('newclass'); // <-- added this line
        }
    },

Answer 2

尝试以下方法

rules: {
            email: "required",
            confirm_email: {
                required: true,

                email: true
            },
            password: {
                required: true,
                minlength: 5
            },
            confirm_password: {
                required: true,
                minlength: 5,
                equalTo: "#password"
            }
        },
        messages: {
            email: {
                required: "Please enter a valid email address."
            },
            confirm_email: {
                required: "Please enter a valid email address.",


            },
            password: {
                required: "Please provide a password",
                minlength: "Your password must be at least 5 characters long"
            },
            confirm_password: {
                required: "Please provide a password",
                minlength: "Your password must be at least 5 characters long",
                equalTo: "Please enter the same password as above"
            }
        },
        highlight:function(element, errorClass, validClass) {
            $(element).parents('.control-group').addClass('error');
        },
        unhighlight: function(element, errorClass, validClass) {
            $(element).parents('#email').removeClass('error');
            $(element).parents('#email').addClass('success');
        }

Answer 3

if($('#emailId').valid() == 1)
  $('#successDivId').addClass('success');
else
//remove class

如果验证失败，它将返回0，否则返回1.

您还可以添加成功回调函数：

...
$('#registration').validate({
        rules: {
            email: "required",
            confirm_email: {
                required: true,

                email: true
            },
            password: {
                required: true,
                minlength: 5
            },
            confirm_password: {
                required: true,
                minlength: 5,
                equalTo: "#password"
            }
        },

        success: function(){
            alert("success"); // you're free to add your CSS class here
        },
...

jQuery Validation插件将成功类添加到另一个元素
