如何防止WebView2(Edge based)打开新窗口 [英] How to prevent WebView2(Edge based) to open a new window

问题描述

在 Webview2 内部，当我打开一个新选项卡时，WindowsForms 外部的一个新窗口会打开.我想阻止这个窗口打开，我该怎么做?

Inside Webview2 when I open a new tab, a new window outside WindowsForms is open. I want to prevent this window to Open, how can I do that?

推荐答案

您可以处理 CoreWebView2.NewWindowRequested 决定新窗口

You can handle CoreWebView2.NewWindowRequested to decide about new window

• 要完全抑制弹出窗口，请设置 e.Handled = true;
• 要在同一窗口中显示弹出内容，请设置 e.NewWindow = (CoreWebView2)sender;
• 要在另一个特定实例中打开，请将 e.NewWindow 设置为另一个 CoreWebView2 实例.

• To completely suppress the popup, set e.Handled = true;
• To show the popup content in the same window, set e.NewWindow = (CoreWebView2)sender;
• To open in another specific instance, set e.NewWindow to the other CoreWebView2 instance.

例如:

//using Microsoft.Web.WebView2.Core;
//using Microsoft.Web.WebView2.WinForms;

WebView2 webView21 = new WebView2();
private async void Form1_Load(object sender, EventArgs e)
{
    webView21.Dock = DockStyle.Fill;
    this.Controls.Add(webView21);
    webView21.Source = new Uri("Https://stackoverflow.com");
    await webView21.EnsureCoreWebView2Async();
    webView21.CoreWebView2.NewWindowRequested += CoreWebView2_NewWindowRequested;
}

private void CoreWebView2_NewWindowRequested(object sender,
    CoreWebView2NewWindowRequestedEventArgs e)
{
    e.NewWindow = (CoreWebView2)sender;
    //e.Handled = true;
}
