I am deeply nesting promises and need to send some progress that occurs up the chain. Let's assume this:
function longRunningAsync() {
return new WinJS.Promise(function (c, e, p) {
// eventually
p('progress happened');
});
}
function doWork() {
var promises = files.map(function(file) {
return longRunningAsync()
.then(doSomethingElse)
.then(doAnotherThing)
.then(howAboutAnother);
});
return WinJS.Promise.join(promises);
}
function doAllWork() {
doWork()
.then(
function onComplete() {
},
function onError() {
},
function onProgress() {
}
);
}
I would expect the progress that occurs at the top to float all the way to the bottom but it does not. How do I achieve this sort of thing?
