xamarin.forms Handle Clicked event on WebView

You can use the HybridWebView from XLabs, and use javascript injection to invoke and handle clicks in your Xamarin control. The injected javascript code can add a click-event listener at capture stage. When a click is detected it uses Native callback to send information back to C# code.

For example - you can define a custom control like this:

public class ClickEventArgs : EventArgs
{
    public string Element { get; set; }
}

public class ClickableWebView : XLabs.Forms.Controls.HybridWebView
{
    public event EventHandler<ClickEventArgs> Clicked;

    public static readonly BindableProperty ClickCommandProperty =
        BindableProperty.Create("ClickCommand", typeof(ICommand), typeof(ClickableWebView), null);

    public ICommand ClickCommand
    {
        get { return (ICommand)GetValue(ClickCommandProperty); }
        set { SetValue(ClickCommandProperty, value); }
    }

    public ClickableWebView()
    {
        LoadFinished += (sender, e) => 
            InjectJavaScript(@"
            document.body.addEventListener('click', function(e) {
                e = e || window.event;
                var target = e.target || e.srcElement;
                Native('invokeClick', 'tag='+target.tagName+' id='+target.id+' name='+target.name);
            }, true /* to ensure we capture it first*/);
        ");

        this.RegisterCallback("invokeClick", (string el) => {
            var args = new ClickEventArgs { Element = el };

            Clicked?.Invoke(this, args); 
            ClickCommand?.Execute(args);
        });
    }
}

Sample XAML usage

<local:ClickableWebView 
    Uri="https://google.com" 
    Clicked="Handle_Clicked"
/>

and sample code-behind

void Handle_Clicked(object sender, CustomWebView.ClickEventArgs e)
{
    Xamarin.Forms.Application.Current.MainPage.DisplayAlert("WebView Clicked", e.Element, "Dismiss");
}

** Output **

Alternatively, you can also bind ClickCommand property to implement this using MVVM pattern.

I am using this hack: put the WebView in a Grid and insert a BoxView in the same cell. Then put a handler on the BoxView.
