Question

What does webview.evalJS() return?

The documentation says this:

invoke JavaScript inside the context of the webview and optionally, return a result

I would actually like to get something back, but I'm not sure how. I tried a function call with a "return", It ran, but the result did not get returned. I guess that makes sense. In most languages I guess something like eval() would return <stdout>? If that is the case here, how would I write to stdout from javascript in a webview?

I was stumped for a while and then I realized I needed to do it in an event to ensure the window was loaded. BTW this was in an iPhone

var webView = Ti.UI.createWebView({url:"http://www.google.com"});
win1.add(webView);

webView.addEventListener('load',function(e)
{
    var cookies = webView.evalJS("document.cookie").split(";"); 
    Ti.API.info( "# of cookies -> " + cookies.length  );
    for (i = 0; i <= cookies.length - 1; i++) {
            Ti.API.info( "cookie -> " + cookies[i] );
    }
});
