最も簡単な方法は、IMOアクションフィルタ属性を作成することです。次に、コントローラーにタグを付けるだけです(またはMVC3のグローバルフィルターに追加する)。
は、ここに属性です:IE6用
/// <summary>
/// If the user has IE6, this will present them with a page that tells them they have a crappy old browser. It gives them options to upgrade but they can also
/// choose to proceed anyway. This check is done only when they first visit the site. A cookie also prevents unnecessary future checks, so this won't slow the app down.
/// </summary>
public class WarnAboutIE6Attribute : ActionFilterAttribute
{
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
var request = filterContext.HttpContext.Request;
//this will be true when it's their first visit to the site (will happen again if they clear cookies)
if (request.UrlReferrer == null && request.Cookies["browserChecked"] == null)
{
//give old IE users a warning the first time
if (request.Browser.Browser.Trim().ToUpperInvariant().EqualsExact("IE") && request.Browser.MajorVersion <= 6)
{
filterContext.Controller.ViewData["RequestedUrl"] = request.Url.ToString();
filterContext.Result = new ViewResult { ViewName = "InternetExplorerOldWarning" };
}
filterContext.HttpContext.Response.AppendCookie(new HttpCookie("browserChecked", "true"));
}
}
}
この属性をチェックし、それが存在だ場合、それはあなたが作成する必要があり、「InternetExplorerOldWarning」ビューをレンダリングします。この警告はCookieを使用することで1回のみ表示されます。もちろん、あなたはそれを微調整することもできます。私の見解では、他のブラウザを更新またはダウンロードするためのリンクを提供しました。私も彼らにIE6を続ける機会を与えました。それを確認してください:
<h3>
Your Internet Explorer is Outdated</h3>
<div class="warning">Your version of Internet Explorer is a bit too old and unfortunately won't work well with this site.</div>
<p>Have no fear. You have options and in just a few minutes you can be rocking out in our app:</p>
<ul>
<li>If you have FireFox, Safari, or Google Chrome already on your computer use one of them for Takeoff instead.</li>
<li>Upgrade to the <a href="http://www.microsoft.com/windows/internet-explorer/worldwide-sites.aspx">latest Internet Explorer.</a> You can download and install right away. Even Microsoft recommends you do this.</li>
<li>Download an Internet Explorer alternative. We recommend <a href="http://www.mozilla.com/en-US/firefox/firefox.html">FireFox</a>, <a href="http://www.apple.com/safari/download/">Safari</a>, or <a href="http://www.google.com/chrome">Google Chrome</a>. Choose one or all because each is great!</li>
</ul>
<p>This warning page will only show once. If you really want to use Takeoff with your current Internet Explorer, we won't stop you. But beware, it will probably look like garbage!</p>
<p>Whatever dude, I want to <a href="@ViewData["RequestedUrl"] ">my old, insecure, scary, dangerous version</a> of Internet Explorer.</p>
</div>
非常にきれいな溶液です。どうもありがとう。 – Gopinath
完全なコードは必要なく、ブラウザの情報( 'request.Browser.Browser'と' request.Browser.MajorVersion')にアクセスするのがポイントでした。よくやった。 – nrod
