I am making a series of http requests and I need to file the results into a list object when they return. I'm using angular promises.
Because the promises only resolve after the for loop is finished, they all get filed into the last index of list.
for (var i = 0;i < list.length; i+=1) {
Promise.do(action).then(function(result) {
list[i] //i is always at last index because the for loop has already completed
}
}
I would try to use $q.all for this:
var promises = [];
for (var i = 0; i < list.length; i += 1) {
promises.push(Promise.do(action));
}
$q.all(promises).then(function(results) {
console.log(results);
});
From the documentation:
Returns a single promise that will be resolved with an array/hash of values, each value corresponding to the promise at the same index/key in the promises array/hash. If any of the promises is resolved with a rejection, this resulting promise will be rejected with the same rejection value.
