问题:

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.

回答1:

$scope.employees is the object to be saved to a file

$scope.savedJSON = angular.toJson($scope.employees,true); var blob = new Blob([$scope.savedJSON],{    type: "application/json;charset=utf-8;" }); var downloadLink = document.createElement('a'); downloadLink.setAttribute('download', 'sampleJSON.txt'); downloadLink.setAttribute('href', window.URL.createObjectURL(blob)); downloadLink.click();

回答2:

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));
