Question

问题很简单但很烦人。我有一个按钮，点击事件只是打开一个链接

HtmlPage.Window.Navigate(uri, "_blank");

但它一直被浏览器阻止。我搜索了很多。似乎每个人都在使用这种方法，但没有人提到新的选项卡/窗口被阻止。那我该怎么办？

更新

问题解决了。似乎要导航到外部网页，应该使用HyperlinkButton。这不会被浏览器阻止。

“要启用用户导航到其他网页，您可以使用HyperlinkButton控件并将NavigateUri属性设置为外部资源，并设置TargetName属性以打开新的浏览器窗口。” --- MSDN, Silverlight - External navigation

<HyperlinkButton NavigateUri="http://www.microsoft.com" Content="Go to Microsoft" TargetName="_blank" />

PS。 HtmlPage.PopupWindow也被浏览器阻止。在我看来，没有用户手动禁用块，HtmlPage.Window.Navigate和HtmlPage.PopupWindow是无用的。

Answer 1

您是否考虑过Silverlight 3和4中的System.Windows.Browser.HtmlPage.PopupWindow(uri, "_blank", null)？

您可以通过HtmlPopupWindowOptions

设置一组选项，而不是最后一个空值

Answer 2

您可以像这样使用System.Windows.Browser。 HtmlPage.Window.Eval ：

    HtmlPage.Window.Eval("mywindowopener('http://www.google.com'")

调用javascript函数“mywindowopener”并传递一个URL。然后在你的Javascript：

    function mywindowopener(uri) {
        window.loginDialog = window.open(uri, "popupwindow", 
        "height=320,width=480,location=no,menubar=no,toolbar=no");
    }

“HtmlPage.Window.Eval”将绕过弹出窗口阻止程序，而“HtmlPage.Window.Invoke（mywindowopener，url）”或“HtmlPage.PopupWindow”则不会。

Silverlight代码：

    public static void OpenWindow(string url, WindowTarget target = WindowTarget._blank)
    {
        // This will be blocked by the pop-up blocker in some browsers
        // HtmlPage.Window.Navigate(new Uri(url), target.ToString());

        // Workaround: use a HyperlinkButton, but do make sure for IE9, you need to have
        //   <meta http-equiv="x-ua-compatible" content="IE=8" />
        // and for all browsers, in the Silverlight control: 
        //   <param name="enableNavigation" value="true" />
        // Also, it seems the workaround only works in a user-triggered event handler
        //

        HyperlinkButton hb = new HyperlinkButton()
        {
            NavigateUri = new Uri(url),
            TargetName  = target.ToString()
        };
        (new HyperlinkButtonAutomationPeer(hb) as IInvokeProvider).Invoke();
    }

包含Siverlight控件的Html页面：

<!--
http://stackoverflow.com/tags/x-ua-compatible/info
X-UA-Compatible is a IE-specific header that can be used to tell modern IE versions to
use a specific IE engine to render the page. For example, you can make IE8 use IE7 mode
or tell IE to use the newest available rendering engine.
-->
    <meta http-equiv="x-ua-compatible" content="IE=8" />

<!-- If we don't have the the above meta tag, Silverlight HyperlinkButton won't work in IE9
     Some Security issue (Unathorized access exception)

TODO:
  1. Check if IE10 has the same issue or not;
  2. Test this in IE7 or IE6.
