توصیه تیم کروم به عدم استفاده‌ی از alert/confirm/prompt

alert()/confirm()/prompt() dialogs are being changed. Rather than being app-modal, they will be dismissed when their tab is switched from. (Safari 9.1 already does this.) This is fully enabled on the canary and dev channels and partially enabled on the beta and stable channels, and will be enabled more in the future.

روش محدود کردن اکشن متدهای ASP.NET Core به درخواست‌های صرفا Ajax ای
Allow only Ajax requests for an action in ASP.NET Core

ASP.NET Core offers attributes such as [HttpGet] and [HttpPost] that allow you to restrict the HTTP verbs used to invoke an action. You can also use HttpRequest object's Method property to detect the HTTP verb behind the current request. However, at times you need to know whether a request is an Ajax request or not. You may also need to restrict an action only to Ajax calls. Although thee is no inbuilt way to accomplish this task, you can easily implement such a feature in your application. This article discusses how.
