问题描述

我有一个 asp.net mvc3 项目,我在其中使用淘汰绑定对表格进行了批量编辑.我想在保存数据的同时进行诸如必需和数字验证之类的验证.有没有更简单的方法来进行淘汰验证.PS:我没有使用表格.

I have asp.net mvc3 project where I do a bulk edit on a table with knockout binding. I want to do validations like required and number validations while saving data. Is there any easier way to do knock out validations.PS: I am not using forms.

推荐答案

看看 Knockout-Validation设置和使用 knockout 文档 中描述的内容.下:现场示例 1:强制输入为数字

Have a look at Knockout-Validation which cleanly setups and uses what's described in the knockout documentation. Under: Live Example 1: Forcing input to be numeric

您可以在 Fiddle 中实时查看

更新:fiddle 已更新为使用最新的 KO 2.0.3 和 ko.validation 1.0.2,使用 cloudfare CDN url

UPDATE: the fiddle has been updated to use the latest KO 2.0.3 and ko.validation 1.0.2 using the cloudfare CDN urls

设置ko.validation:

To setup ko.validation:

ko.validation.rules.pattern.message = 'Invalid.';

ko.validation.configure({
    registerExtenders: true,
    messagesOnModified: true,
    insertMessages: true,
    parseInputAttributes: true,
    messageTemplate: null
});

要设置验证规则,请使用扩展程序.例如:

To setup validation rules, use extenders. For instance:

var viewModel = {
    firstName: ko.observable().extend({ minLength: 2, maxLength: 10 }),
    lastName: ko.observable().extend({ required: true }),
    emailAddress: ko.observable().extend({  // custom message
        required: { message: 'Please supply your email address.' }
    })
};
