knockout.js - Clear error on Knockout-Validation

Question

I have a page setup with Knockout.js and using Knockout-Validation.

During the page load I put another plugin on a select box which fires a change, which fires the validation. I need to be able to clear that error using JS so I can start with a fresh looking UI and give feedback on the form post or select box change.

I can't find anything that allows me to clear an error in Knockout-Validation.

可能遵循淘汰验证中已经实施的更好方法是说property.isModified(false);

如果您要重置整个视图模型，只需遍历所有经过验证的属性并调用它isModified(false)

迟到的答案，但如果有人需要它：

// assuming the ko.observable on the checkbox is called propBoolean
var propBooleanlValid = ko.validation.group(self.propBoolean, { deep: false });
propBooleanlValid .showAllMessages(false);

它将隐藏消息直到下一次验证。

解决它的一种方法是使用自定义验证器，您可以在其中检查视图模型中的标志，例如“ignoreValidation”。如果该标志为真，那么您让验证器通过。

该验证器的外观示例：

viewmodel.userHasPremiumMembership.extend({
    validation: [
        {
            validator: function () {
                if (viewmodel.ignoreValidation) {
                    return true;
                }

                return viewmodel.userHasPremiumMembership();
            },
            message: 'User needs to have premium membership.'
        }
    ]
});

如果您使用实体管理器，请确保在验证中不包含 entityAspect，因为它连接到所有其他实体。另请参阅 如何回滚淘汰验证错误？
