Get value of an element by javascript in awesomium c#

Question

I need to get value of an element by javascript in awesomium and i tried this:

dynamic ch = (JSObject)br.ExecuteJavascriptWithResult
             ("document.getElementById('ltrl').value");

or

JSObject ch = br.ExecuteJavascriptWithResult
             ("document.getElementById('ltrl').value");

but ch is always null how can i get that value?

Answer 1

elegant method from Awesomium examples:

JSObject ch = br.ExecuteJavascriptWithResult("document");
dynamic document = (JSObject)ch ;
if (document == null) return false;
using (document)
{
   document.getElementById('ltrl').value;
}
