validation - jQuery 验证器将字段标记为有效

Question

是否可以使用 jQuery 验证器将字段标记为有效，或者询问另一种方式，以远程其关联的错误映射。我正在使用两种自定义 ajax 验证方法，这意味着我的验证方法不能返回 true 或 false。因此，我尝试使用 showErrors: { field: false } (并标记 validator.invalid.field=false )隐藏错误，但我猜测仍然保留了一些错误映射，这会阻止表单在 onsubmit: true 时提交。如果我设置 onsubmit: true ，即使 ajax 验证字段之一显示错误，表单也会提交!

$(document).ready(function () {

    var validator = $(".formframe").validate({
        groups: { phone: "phone_1 phone_2 phone_3" },
        rules: {
            FirstName: { required: true },
            LastName: { required: true },
            Email: { required: true, email_custom: true },
            phone_1: { required: true }, // these two fields get a phone validation rule
            phone_2: { required: true }, // added upon validation triggered by phone_3 
            phone_3: { required: true, phone: true },
            Address1: { required: true },
            City: { required: true },
            PostalZipCode: { required: true, postalcode: true },
            CustField1: { required: true, range: [1950,2012] }
        },

Answer 1

在向提交按钮添加“取消”类后，我能够执行submitHandler，这阻止了提交时的验证。我尝试设置 onsubmit: false 但允许提交无效的表单。奇怪的是，设置 onsubmit: true (默认行为)并向提交按钮添加 class="cancel"会在表单有效时触发submitHandler，并且不允许提交无效表单。

这是我的submitHandler，它检查validator.invalid 是否为空并且没有空字段。这会阻止在所有字段都为空时提交。我确信有一种更优雅的方法来删除自定义 ajax 验证方法(与它们相关的费用)并让表单在提交之前使用所需的规则重新验证。

submitHandler: function(form) {
    var emptyFields = false;
    $(":input").each(function() {
        if ($(this).val() === "") emptyFields = true;
    });
    if ($.isEmptyObject(validator.invalid) && !emptyFields) { // all is valid, submit
        form.submit();
    } else {
        alert("Please correct some errors");
    }
}

此外，为了让 form.submit() 在 Safari 中工作，我必须将其名称从 name="submit"更改为 name="send"(除了提交之外的其他名称)，请参阅以下链接: http://www.luqmanmarzuki.com/read/20101222/jquery_form_validation_not_submitting_in_safari.html http://api.jquery.com/submit/#comment-106178333
