Can't access Javascript object from C# (CefSharp)

My setup is really simple, in C# (WPF) I have a WebView, that loads my HTML page.

Now I want to have a two way communication between the two.

Calling C# from Javascript works totally fine for me, using RegisterJsObject.

Now I try to execute Javascript from C#, using ExecuteScript.

As long as I only use plain Javascript, such as

ExecuteScript("document.getElementById('test').innerHTML='test'")</code>

it works perfectly fine.

But when I try to access functions I created in Javascript, it fails to execute them.

Javascript:

function test(param) {
    alert(param);
}

C#:

webView.ExecuteScript("test('123')");
Solution

  • I am not sure, what my actual problem was.

    I got it to work by starting from scratch again, starting with basic calls, then getting closer to the actual code I want to execute, and now it somehow works.
