c# - How Can Execute Javascript Commands via GeckoFX

I try to execute a javascript command like alert('test message') via GeckoFX and C# but I can not.

I try without results with Navigate and with ExecuteCommand

My code is

    int i=0;    
    GeckoWebBrowser webBrowser
    webBrowser.Navigate("alert('"+i.ToString()+"');");
    webBrowser.ExecuteCommand("alert('" + i.ToString() + "');");

Can anyone help me?

You can use AutoJSContext to run javascript with geckofx.

Something like:

GeckoWebBrowser browser = ....;

using (AutoJSContext context = new AutoJSContext(browser.JSContext))
{                               
   string result;
   context.EvaluateScript("3 + 2;", out result)
}

See EvaluateScript unittests for more info and examples.

If you are using a super old version of geckofx you may need to get a later version - geckofx
