AngularJsを単純なアプリケーションで使用しています.jsonファイルを呼び出すためにortherのjavascriptファイルに変数を設定したいとします。jsonを解析しようとするとエラーが発生する
これは私のdata.jsです：
[{
var data = require('data_old.json');
var json = JSON.parse(data);
alert(json["date"]); //01/05/2016
alert(json.date); //01/05/2016
"name": "city A",
"elements": [{
"id": "c01",
"name": "name1",
"price": "15",
"qte": "10"
}, {
"id": "c02",
"name": "name2",
"price": "18",
"qte": "11"
}, {
"id": "c03",
"name": "name3",
"price": "11",
"qte": "14"
}],
"subsities": [{
"name": "sub A1",
"elements": [{
"id": "sub01",
"name": "nameSub1",
"price": "1",
"qte": "14"
}, {
"id": "sub02",
"name": "nameSub2",
"price": "8",
"qte": "13"
}, {
"id": "sub03",
"name": "nameSub3",
"price": "1",
"qte": "14"
}]
}, {
"name": "sub A2",
"elements": [{
"id": "ssub01",
"name": "nameSsub1",
"price": "1",
"qte": "7"
}, {
"id": "ssub02",
"name": "nameSsub2",
"price": "8",
"qte": "1"
}, {
"id": "ssub03",
"name": "nameSsub3",
"price": "4",
"qte": "19"
}]
}, {
"name": "sub A3",
"elements": [{
"id": "sssub01",
"name": "nameSssub1",
"price": "1",
"qte": "11"
}, {
"id": "sssub02",
"name": "nameSssub2",
"price": "2",
"qte": "15"
}, {
"id": "sssub03",
"name": "nameSssub3",
"price": "1",
"qte": "15"
}]
}]
}, {
"name": "city B",
"elements": [{
"id": "cc01",
"name": "name11",
"price": "10",
"qte": "11"
}, {
"id": "cc02",
"name": "name22",
"price": "14",
"qte": "19"
}, {
"id": "cc03",
"name": "name33",
"price": "11",
"qte": "18"
}]
}, {
"name": "city C",
"elements": [{
"id": "ccc01",
"name": "name111",
"price": "19",
"qte": "12"
}, {
"id": "ccc02",
"name": "name222",
"price": "18",
"qte": "17"
}, {
"id": "ccc03",
"name": "name333",
"price": "10",
"qte": "5"
}]
}]
そして、これは私がここに私のデータを呼び出して、私のdata.json
[{
"date":"01/05/2016"
}]
です。
angular.module("myApp",['zingchart-angularjs'])
.controller('MainController', ['$scope', '$http', function($scope, $http) {
$scope.chartBase = {
"type": "line",
"plotarea": {
"adjust-layout": true /* For automatic margin adjustment. */
},
"scale-x": {
"label": {
"text": "Above is an example of a category scale" /* Add a scale title with a label object. */
},
"labels": ["name1", "name2", "name3"] /* Add your scale labels with a labels array. */
},
"series": [{
"values": [15, 18, 11] //here the prices of city selected
},{
"values": [10, 11, 14] //here the qte of city selected
}]
};
$scope.chartData = angular.copy($scope.chartBase);
$http.get('data.js')
.then(function(response) {
$scope.cities = response.data; // save the request data
$scope.selectedCity = $scope.cities[0]; // select the first one
$scope.changeCity(); // update chart
}, function(error) { console.log(error); });
$scope.changeCity = function() {
if($scope.selectedSubCity || $scope.selectedCity){ // if something has been selected
$scope.data = ($scope.selectedSubCity || $scope.selectedCity).elements; // update elements field
// initialize the array to be displayed in chart
var labels = [];
var price = {
"values": []
};
var qte = {
"values": []
};
// fill the arrays to be displayed from the selected city (sub city)
angular.forEach($scope.data, function(item, index) {
labels.push(item.name);
price.values.push(parseInt(item.price));
qte.values.push(parseInt(item.qte));
});
console.log($scope.chartData)
// put selected values to the field that is used to render the chart
$scope.chartData["scale-x"].labels = labels;
$scope.chartData.series = [ price, qte ];
}
}
}]);
私はこれを実行すると、ブラウザは、私はこのエラーを持っていることを教えて：
SyntaxError: Unexpected token v in JSON at position 5 at Object.parse (native)
data.js jsonファイルではありませんJavaScriptファイルがあります – Abderrahim
有効なJSON文字列を含むすべてのファイルはJSONファイルです。$ http.get（ 'data.js'）の内容は次のとおりです。 data.jsファイル（ここでは私が指摘したいくつかの行は有効なJSONではありませんので、解析する場合は削除する必要があります）。 –
私はファイルをjavascriptファイルに変換し、いくつかの行を助けてください – Abderrahim
