Yes, everything is asynchronous.
You have sent a request. The response will not be received immediately.
You put a "return" in the function you have assigned to the callback, it
returns this value to... nothing.
What you should do, is something like that -
function GetResponseAndAct(Response)
{
var server = "https://"; + Response.hostname + ":" + Response.port;
}
function getHostParm(parm)
{
chrome.extension.sendRequest({name: parm}, GetResponseAndAct)
}
getHostParm("hostname");
