CefSharp 中控制弹窗的接口是 ILifeSpanHandler ,可以对 OnBeforePopup 进行重写,即可控制是否弹出新窗体。
要实现禁止弹出新窗体-在同一窗口打开,需要在原窗体加载目标Url,即参数targetUrl,并返回结果true,此时将会取消新窗口的创建,并在原窗口加载链接。具体实现方法体的代码如下:
/// <summary>
/// 在自己窗口打开链接
/// </summary>
internal class OpenPageSelf : ILifeSpanHandler
{
public bool DoClose(IWebBrowser browserControl, IBrowser browser)
{
return false;
}
public void OnAfterCreated(IWebBrowser browserControl, IBrowser browser)
{
}
public void OnBeforeClose(IWebBrowser browserControl, IBrowser browser)
{
}
public bool OnBeforePopup(IWebBrowser browserControl, IBrowser browser, IFrame frame, string targetUrl,
string targetFrameName, WindowOpenDisposition targetDisposition, bool userGesture, IPopupFeatures popupFeatures,
IWindowInfo windowInfo, IBrowserSettings browserSettings, ref bool noJavascriptAccess, out IWebBrowser newBrowser)
{
newBrowser = null;
var chromiumWebBrowser = (ChromiumWebBrowser)browserControl;
chromiumWebBrowser.Load(targetUrl);
return true; //Return true to cancel the popup creation copyright by codebye.com.
}
}
在实例化浏览器的时候,指定处理程序
private void MainFrm_Load(object sender, EventArgs e)
{
this.WindowState = FormWindowState.Maximized;
CefSharp.CefSettings settings = new CefSharp.CefSettings();
CefSharp.Cef.Initialize(settings);
CefSharp.WinForms.ChromiumWebBrowser webView = new CefSharp.WinForms.ChromiumWebBrowser("https://www.baidu.com");
webView.Dock = DockStyle.Fill;
webView.LifeSpanHandler = new OpenPageSelf();//这句,是应用我们实现的窗口的打开方式。
this.Controls.Add(webView);
}
