是否有Request.IsMvcAjaxRequest（）相当于jQuery的？ [英] Is there a Request.IsMvcAjaxRequest() equivalent for jQuery?
问题描述
我preFER使用jQuery和我比微软的Ajax库ASP.NET MVC应用程序。我已经加入了一个名为模式为我的行为，我在我的ajax调用设置参数。如果它被设置，我返回JsonViewResult。如果没有提供，我认为这是一个标准的HTTP POST和我返回一个ViewResult。
I prefer to use jQuery with my ASP.NET MVC apps than the Microsoft Ajax library. I have been adding a parameter called "mode" to my actions, which I set in my ajax calls. If it is provided, I return a JsonViewResult. If it isn't supplied, I assume it was a standard Http post and I return a ViewResult.
我希望能够使用jQuery，所以我可以消除我的行动额外的参数时使用类似IsMvcAjaxRequest东西在我的控制器。
I'd like to be able to use something similar to the IsMvcAjaxRequest in my controllers when using jQuery so I could eliminate the extra parameter in my Actions.
有什么在那里，将提供我的控制器内的这种能力或实现它的一些简单的方法？我不想去疯狂写作code，因为加入一个参数的作品，它只是不理想。
Is there anything out there that would provide this capability within my controllers or some simple way to accomplish it? I don't want to go crazy writing code since adding a single parameter works, it just isn't ideal.
