[英]AngularJS : Adding variable into a chain of promises
我正在學習承諾,並在以下方面苦苦掙扎。
在這種情況下,將運行三個功能。
//returns an search query in JSON format
filterSearch()
// searches Parse.com and returns an array of values
.then(performSearch)
// I am passing the array of values to exerciseSearch and a another value (term - string)
.then(function(result) {
exerciseSearch(result, term);
})
// The results from the search is displayed in scope.
.then(function(exercises) {
$scope.allExercises = exercises;
}, function(error) {
console.log('error');
});
承諾鏈應始終具有。的返回對象.then
繼續承諾鏈
//returns an search query in JSON format
filterSearch()
// searches Parse.com and returns an array of values
.then(performSearch)
//(term - string)
.then(function(result) {
return exerciseSearch(result, term); //exerciseSearch should return exercises from fn
})
// The results from the search is displayed in scope.
.then(function(exercises) {
$scope.allExercises = exercises;
return exercises;
}, function(error) {
console.log('error');
});
