WPF webbrowser 判断网页加载完毕

简介：如果网页没有加载完毕就操作网页，将导致出错，所以需要判断网页是否已经加载好了

控件名称为webbrowser

通过LoadCompleted监听事件来触发函数，这里我直接在界面初始化后进行定义

public MainWindow()
        {
            InitializeComponent();
            this.webbrowser.LoadCompleted += new LoadCompletedEventHandler(webbrowser_LoadCompleted);//添加加载完毕触发函数
            Uri uri = new Uri("https://www.baidu.com/");
            webbrowser.Navigate(uri);

        }

然后是处理函数，当加载完毕后，禁用浏览器的滚动条，并且修改WPF标题

 private void webbrowser_LoadCompleted(object sender, NavigationEventArgs e)
        {
            
            mshtml.HTMLDocument dom = (mshtml.HTMLDocument)webbrowser.Document; 
            dom.documentElement.style.overflow = "hidden"; //hiden scroller
            dom.body.setAttribute("scroll", "no"); //disable scroller
                this.Title = "Loading complete.";
        }
