Question

我想在MVC3项目中使用jQuery validate强制我的“同意条款”复选框。我目前从“MS数据注释属性”+“MS MVC3不引人注目的jQuery验证”获得服务器/客户端DRY / SPOT验证。

这是一个独立测试（由MVC3生成的纯HTML）。为什么它不起作用，拜托？运行时，验证确保填写“联系人姓名”字段，但不关心复选框的状态。

设置数据注释属性[必需]没有帮助：
http://forums.89.biz/forums/MVC+3+Unobtrusive+validation+does+not+work+with+checkboxes+(jquery+validation)+and+the+fix+for+it

没关系。对于复选框而言，“必需”意味着什么显然是一场我不想涉足的圣战，MS认为他们比jquery团队更了解。在当地强制执行应该是一个简单的问题：
$("form").validate({ rules: { cbAgreeToTerms: "required" } });

...对吧？不，因为：
http://blog.waynebrantley.com/2011/01/mvc3-breaks-any-manual-use-of-jquery.html
http://pinoytech.org/question/4824071/microsofts-jquery-validate-unobtrusive-makes-other-validators-skip-validation

什么？这是相当臭的cheezy！（恕我直言，当然。）

现在，我尝试了这个解决方案：
http://itmeze.com/2010/12/checkbox-has-to-be-checked-with-unobtrusive-jquery-validation-and-asp-net-mvc-3/
它对我不起作用。这位作者在他/她的文章中使用倒置的CHECKBOX测试的悬空评论和一些货物崇拜使我想知道它是否真的适用于他/她，那么其他伏都教还涉及到什么？

注意我认为JS的最后一个片段相当于清洁剂：
$.validator.unobtrusive.adapters.addBool("brequired", "required"); 这是在上一篇文章中提出的： http://forums.asp.net/p/1648319/4281140.aspx#4281140
但请注意，作者评论说他还没有调试过它。它对我来说不起作用，并且在两行之间阅读，我认为他的意思是它对他不起作用？

unobtrusive.js调用docready解析，所以我试着调用它，但它没有帮助我。
$.validator.unobtrusive.parse(document); 我也发现了一些类似的文章，没有人谈论要求任何类型的初始化。也许他们都在本地编辑原始/公共unobtrusive.js？如果我可以提供帮助，我宁愿不这样做，那不就是适配器的用途吗？

我发现堆叠溢出的文章，大致相同，以及更复杂的例子：
    ASP .Net MVC 3 unobtrusive custom client validation
    Perform client side validation for custom attribute
    http://xhalent.wordpress.com/2011/01/27/custom-unobstrusive-jquery-validation-in-asp-net-mvc-3/
但我没有看到任何与我已经尝试过的不同的东西。

这对人们有用吗？为什么我不能让它为我工作？

只需将您的javascript更改为：

(function ($) {
    // http://itmeze.com/2010/12/checkbox-has-to-be-checked-with-unobtrusive-jquery-validation-and-asp-net-mvc-3/
    $.validator.unobtrusive.adapters.add("mandatory", function (options) {
        options.rules["required"] = true;
        if (options.message) {
            options.messages["required"] = options.message;
        }                
    });            
} (jQuery));

您实际上并不需要编写自己的适配器，只能使用：

(function ($) {
    $.validator.unobtrusive.adapters.addBool("mandatory", "required");
} (jQuery));
