我想验证我的表格，以便在两个空白字段中，至少必须填写一个字段，并且还可以填写两个字段；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>

任何建议如何做到这一点....？

到目前为止我已经尝试过

 jQuery.validator.addMethod("require_from_group", function(value, element, options) {
    alert("xxx");
    var valid = $(options[1], element.form).filter(function() {
        return $(this).val();
    }).length >= options[0];

    if(!$(element).data('reval')) {
        var fields = $(options[1], element.form);
        fields.data('reval', true).valid();
        fields.data('reval', false);
    }
    return valid;
}, jQuery.format("'Please enter either username/ email address to recover password'/Please fill out at least {0} of these fields."));

仍然没有得到富有成效的输出。

您正在尝试使用jQuery Validate pluginvalidator.addMethod的一部分。如果你还没有，你需要在你的代码中包含这个插件。

然后使用require_from_group已经包含在 Validate 插件additional-methods.js文件中的规则。（不要忘记也包含该additional-methods.js文件。）

rules: {
    myfieldname: {
        require_from_group: [1, ".class"]
    }
}
  • 第一个参数是需要的项目数。

  • 第二个参数是class分配给分组中的所有元素。我send为您的两个输入元素添加了一个类。

  • 还可以使用该groups选项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： 根据 Github，该require_from_group方法存在一个未解决的问题。在修复之前，开发人员在下面推荐此解决方案。由于您将手动将修改后的方法添加到代码中，因此无需包含该additional-methods.js文件。

新的工作演示：http: //jsfiddle.net/kE7DR/2/

$(document).ready(function () {

    jQuery.validator.addMethod("require_from_group", function (value, element, options) {
        var numberRequired = options[0];
        var selector = options[1];
        var fields = $(selector, element.form);
        var filled_fields = fields.filter(function () {
            // it's more clear to compare with empty string
            return $(this).val() != "";
        });
        var empty_fields = fields.not(filled_fields);
        // we will mark only first empty field as invalid
        if (filled_fields.length < numberRequired && empty_fields[0] == element) {
            return false;
        }
        return true;
        // {0} below is the 0th item in the options field
    }, jQuery.format("'Please enter either username/ email address to recover password'/Please fill out at least {0} of these fields."));

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

@Sparky 我正在尝试使用您的答案来验证帐户名称和/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，没有消息说必须输入新帐户或密码）。我的代码是：

$(document).ready(function(){
$.validator.addMethod(
        "regex",
        function(value, element, regexp) 
        {
            if (regexp.constructor != RegExp)
                regexp = new RegExp(regexp);
            else if (regexp.global)
                regexp.lastIndex = 0;
            return this.optional(element) || regexp.test(value);
        },
        "Please enter correct Characters."
);
jQuery.validator.addMethod("require_from_group", function (value, element, options) {
    var numberRequired = options[0];
    var selector = options[1];
    var fields = $(selector, element.form);
    var filled_fields = fields.filter(function () {
        // it's more clear to compare with empty string
        return $(this).val() != "";
    });
    var empty_fields = fields.not(filled_fields);
    // we will mark only first empty field as invalid
    if (filled_fields.length < numberRequired && empty_fields[0] == element) {
        return false;
    }
    return true;
    // {0} below is the 0th item in the options field
}, jQuery.format("'Please enter either a new Account name and/or a new password'/Please fill out at least {0} of these fields."));
