I'm a bit confused about your question. If you just want to alter an element in the HTML, Jeremy's answer is the best, and simplest, way to go. If you wanted to call the document's javascript, this should work:

Let's assume that the webbrowser's document contains the following HTML:

    
    
    
    
        
Waiting...
        
    

To invoke the webbrowser document's javascript method, you can use something like this:

private void button1_Click(object sender, EventArgs e)
{
    object o = webBrowser1.Document.InvokeScript("changeDate('june')");
}

No System.Web, ASP, ScriptManagers or Interop are needed. All the tools you need to control webbrowser and document objects and events come with the webbrowser control.
