var result = [];
angular.forEach(cars, function (car) {
if (_matches(car, criteria)) {
result.push(car);
}
});
resultCallback(result);
}, 1000);
};
var _matches = function (car, criteria) {
return angular.toJson(car).indexOf(criteria) > 0;
};
return {
filter: _filter
}
});
A very common requirement when creating an instant search is to cancel the
previously scheduled timeout, replacing it with a new one. It avoids an unnecessary
consumption of resources, optimizing the whole algorithm.
In the following code, we are interrupting the timeout. It can be achieved by calling
the cancel method on the $timeout object that is passing the promise reference as
a parameter:
parking.factory('carSearchService', function ($timeout) {
var filterPromise;
var _filter = function (cars, criteria, resultCallback) {
$timeout.cancel(filterPromise);
filterPromise = $timeout(function () {
var result = [];
angular.forEach(cars, function (car) {
if (_matches(car, criteria)) {
result.push(car);
}
});
resultCallback(result);
}, 1000);
};
var _matches = function (car, criteria) {
