我需要通过提供输入日期来检索服务中的输出数据。数据在服务上执行但我无法将输出数据返回给控制器。我为code.link做了一个plunker Plaunker Link

您需要return
$http.get
和.then
最终修改后的变量,例如obj
。
像这样:
return $http({
url: 'miqaat.json',
method: 'GET',
})
.then(function(response) {
var all_miqaats = response.data.response;
var obj = all_miqaats.find(function(v) {
return v.miqaat_date == dat
});
if (obj == undefined || obj == "") {
console.log("obj = ");
console.log(obj);
obj.isHoliday = "100";
// return obj;
} else {
obj.mq_title = obj.title;
obj.isHoliday = "101";
// return obj;
console.log("Data from Service");
console.log(obj);
}
return obj;
})
并且,由于这会返回promise,因此在控制器中您需要将其更改为:
getMiqaat.findMiqaat($scope.date).then(function(res) {
$scope.miqaat = res;
});
您是否应将.then
和catch
移至controller
取决于您reuse
代码的数量。所以,在我知道细节之前不会发表评论。

app.controller('myCtrl', function($scope, getMiqaat) {
$scope.date = "2017-04-11";
getMiqaat.findMiqaat($scope.date)
.then(function(response) {
var all_miqaats = response.data.response;
var obj = all_miqaats.find(function(v) {
return v.miqaat_date == $scope.date
});
if (obj == undefined || obj == "") {
console.log("obj = ");
console.log(obj);
obj.isHoliday = "100";
$scope.miqaat = obj;
} else {
obj.mq_title = obj.title;
obj.isHoliday = "101";
$scope.miqaat = obj;
console.log("Data from Service");
console.log(obj);
}
})
.catch(function(response) {
response.response = "Internal Server Error!";
});;
});
app.factory('getMiqaat', function($http) {
return {
findMiqaat: function(date) {
var dat = date;
console.log(dat);
return $http({
url: 'miqaat.json',
method: 'GET',
})
}
};
})

通过使用下面提到的代码,它将正常工作。请确保按照你的json匹配键。
控制器代码:
var app = angular.module("myApp", []);
app.controller('myCtrl', function($scope, getMiqaat){
$scope.date = "2017-04-11";
console.log("date ::"+$scope.date);
$scope.status;
$scope.miqaat;
getMiqaatData();
function getMiqaatData() {
getMiqaat.findMiqaat($scope.date)
.then(function (response) {
$scope.miqaat = response.data.response[0];
}, function (error) {
$scope.status = 'Unable to load data: ' + error.message;
});
}
});
app.service('getMiqaat', function($http){
this.findMiqaat = function(date){
var dat = date;
console.log(dat);
return $http({
url: 'miqaat.json',
method: 'GET',
});
}
})
Json :
{
"status":true,
"message":"List of the miqaats",
"response":[
{"miqaat_date":"2017-04-11",
"mq_title":" New Year",
"isHoliday" :"101"
},
{"miqaat_date":"2017-04-09",
"mq_title":"Some Fest",
"isHoliday" :"101"
}
]
}
