I am using Q for my promise library.
I have a promise that if success calls and array of promises.
The code is:
getCount(client).then(function (count) { //
when successful create a
var promises = [];
// array of promises to be processed next
for (var i = 0; i < count; i++) {
// in order
promises.push(az(client, i));
}
return Q.all(promises);
}).then(function(results) {
console.log("everything went right. All results:", results);
}, function(err) {
console.log("something (either getCount, or one of the az
calls) blew up", err);
});
so az takes and index and returns a value. If index === 1 it throws.
function az(client, index) {
var xml = "<urn:mgmtISCSIGetTargetList> </urn:mgmtISCSIGetTargetList>";
client.MgmtServer.MgmtServer.asynCall(xml, function (err, result) {
if (err) {
return deferred.reject(err);
}
if (1 === index) {
console.log('index 1 is bad news');
return deferred.reject("Blew up");
}
console.log('returning with index ' + index + ' returning ' +
(index + 30));
deferred.resolve(index + 30);
}
);
return deferred.promise;
};
when I run this, I see this output:
everything went right. All results: [ 3, 3, 3 ]
returning with index 0 returning 30
index 1 is bad news
returning with index 2 returning 32
Output of getCount first then az 1 2 3 and the exception for 1 never
sending me to console.log("something (either getCount, or one of the az
calls) blew up", err);
Am I using my array of promises incorrectly?
