1.设置js弹窗控制器
webView.JsDialogHandler = this; //js弹窗控制
2.实现接口方法
public bool OnJSAlert(IWebBrowser browser, string url, string message) { MessageBox.Show(message); return true; //阻止js弹 } public unsafe bool OnJSConfirm(IWebBrowser browser, string url, string message, bool* retval) { DialogResult result = MessageBox.Show(message, "提示", MessageBoxButtons.YesNo); bool value = result == DialogResult.Yes ? true : false; // retval = (bool *)GCHandle.Alloc(value).AddrOfPinnedObject().ToPointer(); //获取托管内存地址,异常 // retval = &value; //改变指针失败 *retval = value; return true; } public unsafe bool OnJSPrompt(IWebBrowser browser, string url, string message, string defaultValue, bool* retval, ref string result) { //交互消息 string r = string.Empty; this.Invoke(new Action(() => { r = Microsoft.VisualBasic.Interaction.InputBox(message, "提示", defaultValue); })); result = r; if (result == defaultValue) { *retval = false; } else { *retval = true; } return true; }
