AngularJS Promise retries

阅读更多关于 AngularJS Promise retries

问题 I am having some trouble getting a retry function to work and was hoping for some assistance. I have a $resource that I want to have called until a success condition occurs or the maximum retries has been exceeded. The issue I seem to be running into is that within my retry function I am calling another promise and that is where the condition would be checked.

AngularJS then() behaves differently than success()-error() [duplicate]

阅读更多关于 AngularJS then() behaves differently than success()-error() [duplicate]

问题 This question already has answers here : Why are AngularJS $http success/error methods deprecated? Removed from v1.6? (2 answers) Closed last year . As the success() and error() functions are deprecated in AngularJS, I am updating my codes, replacing them with then() . Now according to my understanding, these two pieces of codes should behave identically: $http .get(/* some params */) .success(function() { // success cases here }) .error(function() { // error cases here }); And $http .get(/*

Stopping JavaScript Promises from Propagating

阅读更多关于 Stopping JavaScript Promises from Propagating

Imagine I have a promise chain like the one below. If func2 is called, I would like to avoid func3 or func4 from being called altogether. AsyncFunction() .then(func1, func2) .then(func3, func4) At the moment, If I throw an error in func2, func4 would be called. If I return a value in func2, func3 seems to be called. I am using Angular $q. Use nesting for branching control flow. In your case, it would look like this: AsyncFunction().then(function(res) { return func1(res).then(func3, func4); }, func2); 来源： https://stackoverflow.com/questions/27218787/stopping-javascript-promises-from-propagating
