推荐答案
You could use a module like the angular-file-saver. It might be slightly involved - but the steps are outlined on the module's NPM page.
Basically, you need to install the angular-file-saver module and then modify your myApp module to inject it like this:
var app = angular.module('myApp', ['ngFileSaver']);
///您还需要更改控制器以包括FileSaver和Blob参数:
//You also need to change your controller to include the FileSaver and Blob params:
app.controller('myCtrl', ['$http','FileSaver', 'Blob', function($http, FileSaver, Blob){
//now you can use the file save inside your $scope.foo like this:
$scope.foo = function() {
//get content of the remote URL (take care of the CORs)
$http.get('http://www.thehindu.com/news/').success(function (pageContent){
//here you create file and save content to it
var data = new Blob([pageContent], {type: 'text/plain;charset=utf-8' });
FileSaver.saveAs(data, 'text.txt');
});
};
}]);
