Hi,
you can call javascript functions via lua, so making a request looks like this:
js("sendReq(""..Values["arg0"].Int.."",""..Values["arg1"].String.."")")
And you would add a function in a html script tag to take the call and make request or something else:
function sendReq(arg0, arg1)
{
r = new XMLHttpRequest();
r.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
r.send('name0='+escape(encodeURI(arg0)) + '&name1=' + escape(encodeURI(arg1)));
}
