This is an interesting question. I'm using a simple JSON Get request to get all the competetions according to date, and show result as a list.
the JSON response is kind of :
[
{
"id":33
"competition":565
},
{
"id":66
"competition":345
}
]
Then I should make another json request to get the name of each json item :
myserver.com/{id}
which look like :
{
"name":"Serie A"
}
I want to show a list of all the names of the competetions I have on the first json request according to date.
here is my angular js code for showing the list of a simple JSON request :
<div ng-controller="customersCtrl">
<ul>
<li ng-repeat="m in matches">
{{ m.id }}
</li>
</ul>
</div>
<script>
var app = angular.module('starter', []);
app.controller('customersCtrl', function($scope, $http) {
$http.get("http://Myserver.com/matches?date=2015-05-19")
.success(function (response) {$scope.matches = response;});
</script>
You can iterate through the matches and get the names with a new call:
app.controller('customersCtrl', function($scope, $http) {
$http.get("http://myserver.com/matches?date=2015-05-19")
.success(function (response) {
$scope.matches = response;
for (var i = 0; i < response.length; i++) {
setName($scope.matches, i);
}
});
var setName = function (matches, index) {
$http.get("http://myserver.com/" + matches[index].id)
.success(function (response) {
matches[index].name = response.name;
});
}
});
Below code will first fetch all the competitions and then using their id
s it will fetch names
all the events parallely. it will give all the competition with details in one go only.
Warning: If you have large numbers of all competition then it will make same number of calls to get competition details all of them.
app.service('competition', function($http) {
this.getAllCompetitions = function() {
var baseUrl = 'http://Myserver.com';
return $http.get(baseUrl + '/matches?date=2015-05-19')
.then(function(allCompetitions) {
/* sample `data`
[
{
"id":33
"competition":565
},
{
"id":66
"competition":345
}
]
*/
var qArr = [];
allCompetitions.forEach(function(competition, index) {
var promise = $http.get(baseUrl + '/' + competition.id)
.then(function(competitionDetail) {
/* sample `competitionDetail`
{
"name":"Serie A"
"competition":565
}
*/
return {
competitionDetail: competitionDetail,
index: index
};
});
aArr.push(promise);
});
return $q.all(qArr).then(function(listOfData) {
listOfData.forEach(function(item) {
allCompetitions[item.index] = angular.extend(allCompetitions[item.index], item.competitionDetail);
});
return allCompetitions;
});
});
}
});
