Call .Net from javascript in CefSharp 1 - wpf

Question

I'm just learning C# WPF and has been successfully implemented CefSharp, how to call .NET function from javascript, that is loaded in CefSharp?

Answer 1

1. Construct WebView via WebView webView = new WebView(url)
2. Then you can invoke RegisterJsObject method to register a js object.
3. Use javascript to invoke this js object.

The example as below:

public class CallbackObjectForJs{
    public void showMessage(string msg){//Read Note
        MessageBox.Show(msg);
    }
}

WebView webView = new WebView("http://localhost:8080");
webView.RegisterJsObject("callbackObj", new CallbackObjectForJs());

javascript code at frontend:

<script type="text/javascript">
    callbackObj.showMessage('message from js');
</script >

Note: The first character can't be upper of showMessage method at CallbackObjectForJs
