sha*_*non 44 asp.net-mvc jquery jquery-validate
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.
这是一个独立的测试(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:

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.在本地强制应该是一个简单的问题:
$("form").validate({ rules: { cbAgreeToTerms: "required" } });
...对？不,因为:

http://pinoytech.org/question/4824071/microsofts-jquery-验证,不显眼,让-其他-验证跳过验证
什么？这是相当臭的cheezy!(恕我直言,当然.)
现在,我已经试过这个解决方案:
http://itmeze.com/2010/12/checkbox-has-to-be-checked-with-unobtrusive-jquery-validation-and-asp-net-mvc-3/
和它对我不起作用.这位作者在他/她的文章中早先对他们/她的翻译CHECKBOX测试的悬空评论和一些货物使用使得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
但请注意作者评论他尚未调试它.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？
我发现堆栈溢出文章,大致相同,以及更复杂的示例:
ASP .Net MVC 3不显眼的自定义客户端验证
执行自定义属性的客户端验证
http://xhalent.wordpress.com/2011/01/27/ custom-unobstrusive-jquery-validation-in-asp-net-mvc-3 /
但是我没有看到任何与我已经尝试过的不同的东西.
这真的适合人们吗？为什么我不能让它为我工作？

我在这里总结了正确工作的源代码,这是源于应用已接受的答案.希望你觉得它有用.

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));
