$q.all - 访问个人承诺结果?
$q.all - access individual promise result?
我对 $q angular promises 有点陌生。这是我的代码结构:
$q.all(promises).then(function(results) {
results.forEach(function(data, status, headers, config) {
console.log(status);
});
$scope.saveDocumentCaseState();
}, function errorCallBack(response) {
console.log('error while mass update case entries');
console.log(response);
$scope.submitToWsSuccessful = 2;
});
当每个承诺在下一个承诺之前执行时,是否有可能访问每个承诺的结果?
因此,假设您从名为 promiseFactory
的 angular 工厂收到一个包含任意数量承诺的数组:
var promises = promiseFactory.getPromises(); // Returns an array of promises
promises.forEach(function(p){
p.then(promiseSuccess, promiseError);
function promiseSuccess(){
// Do something when promise succeeds
}
function promiseError(){
// Do something when promise errors
}
});
$q.all(promises).then(allSuccess, allError);
function allSuccess(){
// All calls executed successfully
}
function allError(){
// At least one of the calls failed
}
