我想将它保存到JSON文件，当我点击一个按钮或什么的。

解决方案

角。的toJSON 应该帮助你。

  VAR应用= angular.module（'对myApp'，[]）;app.controller（'MainCtrl'，['$范围，$过滤'，函数（$范围，$过滤器）{
$ scope.employees = [
{名字：约翰，姓氏：李四，
  城市：班加罗尔，国家：卡纳塔克邦，}，{名字：安娜，姓氏：史密斯
   城市：海得拉巴，国家：AndraPradesh，}，{名字：彼得，姓氏：琼斯
  城市：孟买，国家：马哈拉施特拉邦，}，
];$ scope.savedJSON ='';$ scope.save =功能（）{
    $ scope.savedJSON = angular.toJson（$过滤器（'过滤器'）（$ scope.employees，$ scope.searchText））;
};
}]）;VAR BLOB =新的Blob（[scope.save] {
类型：应用/ JSON的;字符集= UTF-8;
}）;
downloadLink.attr（'href属性，window.URL.createObjectURL（BLOB））;
 

I have a variable with huge data some thing like this.

$scope.employees = [
    {"firstName":"John", "lastName":"Doe",
      "city": "Bangalore","State":karnataka,},

    {"firstName":"Anna", "lastName":"Smith",
       "city": "Hyderabad","State":AndraPradesh,},

    {"firstName":"Peter", "lastName": "Jones",
      "city": "Mumbai","State":Maharastra,},
];

I want to save it to JSON file, when I click a button or something.

解决方案

angular.toJson should help you out.

var app = angular.module('myApp', []);

app.controller('MainCtrl', ['$scope', '$filter', function ($scope, $filter) {
$scope.employees = [
{"firstName":"John", "lastName":"Doe",
  "city": "Bangalore","State":karnataka,},

{"firstName":"Anna", "lastName":"Smith",
   "city": "Hyderabad","State":AndraPradesh,},

{"firstName":"Peter", "lastName": "Jones",
  "city": "Mumbai","State":Maharastra,},
];



$scope.savedJSON = '';

$scope.save = function () {
    $scope.savedJSON = angular.toJson($filter('filter')($scope.employees, $scope.searchText));
};
}]);

var blob = new Blob([scope.save],{
type: "application/json;charset=utf-8;"
});
downloadLink.attr('href', window.URL.createObjectURL(blob));
