我有这个表格...

<form action="" method="post" id="register">
    <ol class="subproduct">
        <li>
            <input type="checkbox" name="extra2" value="Multidispositivo" />
            <p class="checkbox"></p>

        </li>
        <li>
            <input type="checkbox" name="extra2" value="Multidispositivo" />
            <p class="checkbox"></p>
                <h3>Multidispositivo <span class="price"><span>+2</span>€&lt;/span></h3>

            <p>Disfrute la conexión en hasta 3 dispositivos simultáneamente</p>
        </li>
        <li>
            <input type="checkbox" name="extra2" value="15 min extra" />
            <p class="checkbox"></p>
                <h3>15 min extra <span class="price"><span>+4</span>,10€&lt;/span></h3>

        <li>
            <input type="checkbox" name="extra2" value="Multidispositivo" />
            <p class="checkbox"></p>
                <h3>Multidispositivo <span class="price"><span>+2</span>€&lt;/span></h3>

            <p>Disfrute la conexión en hasta 3 dispositivos simultáneamente</p>

    </ol>

            <input id="register-submit" type="submit" value="Conectar" />
        </p>
    </div>
</form>

如果每个人都没有输入/选择/复选框，我需要给出一个错误....

目前我有这个

$(document).ready(function () {
    $('#register').submit(function () {
        $("#email-login").each(function () {
            if ($(this).val() === "") {
                $("#email-login").after('<span class="register-error email-error">email</span>');
            }
        });
        $("#password-login").each(function () {
            if ($(this).val() === "") {
                $("#password-login").after('<span class="register-error password-error">password</span>');
            }
        });
        $("#name").each(function () {
            if ($(this).val() === "") {
                $("#name").after('<span class="register-error name-error">name</span>');
            }
        });

        if ($("#gender-female").is(':checked')) {
            //$(this).prop('checked',false);
            $("#gender-male").after('<span class="register-error female-error"></span>');
            $("#gender-female").hide().after();
        } else {
            //$(this).prop('checked',true);
            $("#gender-female").after('<span class="register-error female-error"></span>');
            $("#gender-male").hide().after();
        }

        $(".data select").each(function () {
            if ($(this).val() === "") {
                $(".data select").after('<span class="register-error select1-error">age</span>');
            }
        });
        $(".data2 select").each(function () {
            if ($(this).val() === "") {
                $(".data2 select").after('<span class="register-error select2-error">plage</span>');
            }
        });
        $("#postalcode").each(function () {
            if ($(this).val() === "") {
                $("#postalcode").after('<span class="register-error postalcode-error">postcode</span>');
            }
        });
        $(".terms checkbox").each(function () {
            if ($(this).val() === "") {
                $(".terms checkbox").after('<span class="register-error select2-error">agree</span>');
            }
        });
        return false;

    });


});


$(document).on('click', '.register-error', function () {
    $(this).remove();
    return false;
});

它的输入字段很好，但我不能让性别成为一个或者在点击时隐藏错误，我不知道如何让 jquery 来查找正在填写的内容？

有任何想法吗？

// Validate on submit
$('form').submit(function() { return validateForm(); });

// validate on change
$(':input').change(function() { validateForm(); });

var validateForm = function() {
    var validates = true;

    $(':input') // Find all form elements
        .not('input[type="submit"]') // Exclude the submit button
        .each(function(i) {
            var $this = $(this), // ~cache the jQuery object
                selected = $this.is(':checkbox') ? this.checked : !!$this.val(); // Check selected checkbox or a required value

            // TODO: Check for radio grouped buttons

            console.log(i, selected); // DEBUG

            // Toggle "invalid" class
            $this.toggleClass('invalid', !selected);

            if (!selected) validates = false;
        });

    console.log('Form validates', validates); // DEBUG
    return validates;
};

首先，您没有以正确的方式使用单选按钮。name 属性必须相同，否则它们不会被分组。

示例：http ://www.w3schools.com/html/tryit.asp?filename=tryhtml_radio

<form action="">
<input type="radio" name="sex" value="male">Male<br>
<input type="radio" name="sex" value="female">Female
</form>

然后你可以这样做来获取检查的值。

var value = $("input[@name=sex]:checked").val();

如果value未定义，则不检查它们。
