jQuery验证，在两个空白字段中，必须至少填写一个字段或同时填写两个字段

我想验证我的表单，以便在两个空白字段中，至少有一个字段必须填写，两个字段也可以填写；但不能将任何字段留空。

我正在使用jquery-1.9.1-min.js，这是我的html页面

<form action="#" class="send_form" id="forgot_pass_form" method="POST">
            <fieldset>
                <div class="send_row">
                    <label class="padding-top10">Email</label>
                    <input type="text" class="send_email" id="email" name="email" />
                    <em>You need to type an email address</em>
                </div>

                <div class="send_row option">OR</div>

                <div class="send_row">
                    <label class="padding-top10">Username</label>
                    <input type="text" class="send_username" id="uname" name="uname" />
                </div>


                <div class="send_row send_submitforgotuser">
                    <input type="submit" value="Submit" />
                </div>
            </fieldset>
            </form>

仍然没有获得琐碎的输出。

您正在尝试使用的验证程序.addMethod是的一部分。如果还没有，您需要在代码中包含此插件

然后使用已经属于的

require\u from\u group

规则。（不要忘记也包括

附加方法.js

文件。）

• 第一个参数是需要的项目数
• 第二个参数是分配给分组中所有元素的

  类

  。我在两个输入元素中添加了一个

  send

  类

• 还可以使用将两条消息合并为一条消息

jQuery：

$(document).ready(function () {

    $('#forgot_pass_form').validate({ // initialize the plugin
        groups: {  // consolidate messages into one
            names: "uname email"
        },
        rules: {
            uname: {
                require_from_group: [1, ".send"]
            },
            email: {
                require_from_group: [1, ".send"]
            }
        }
    });

    //  for your custom message
    jQuery.extend(jQuery.validator.messages, {
        require_from_group: jQuery.format("'Please enter either username/ email address to recover password'/Please fill out at least {0} of these fields.")
    });

});

编辑：使用

require\u from\u group

方法。在修复之前，开发人员将在下面推荐此解决方案。由于您需要将修改后的方法手动添加到代码中，因此无需包含

additional methods.js

文件

新的工作演示：

$（文档）.ready（函数（）{
jQuery.validator.addMethod（“需要来自_组的_”），函数（值、元素、选项）{
var numberRequired=选项[0]；
var选择器=选项[1]；
变量字段=$（选择器，element.form）；
var filled_fields=fields.filter（函数（）{
//与空字符串相比更为清晰
返回$（this）.val（）！=“”；
});
var empty_fields=fields.not（filled_fields）；
//我们只将第一个空字段标记为无效
if（填充字段.length

@Sparky我正在尝试使用您的答案验证帐户名和/或密码的更新。我输入原始帐户名和密码，然后单击更新按钮，执行原始帐户名和密码的验证（即，没有消息表明必须输入新帐户或密码）。我的代码是：
