通知Angular变量已更改 [英] Notify Angular a variable has changed

问题描述

我只是从Angular开始，并有一个简短的问题:

I'm just starting with Angular and have a quick question:

var data = JSON.parse('[{"name": "Joe","account": "12355845454","rent": "500"}]');

angular.module('ngAppRentManager', []).
controller('RentCtrl', ['$scope', function ($scope) {
    $scope.tenants = data;
}]);

setTimeout(function () {
    data = JSON.parse('[{"name": "Sara","account": "54874","rent": "600"}]');
    console.log("Poke Angular!");
}, 2000);

当我的变量 data 更改时.如何告诉Angular更新模型?

When my variable data has changed. How do I tell Angular to update the model?
