AngularJS控制器controller之间如何通信

function Sandcrawler($scope) {

$scope.location = "Mos Eisley North";

$scope.move = function(newLocation) {

    $scope.location = newLocation;

}

};

function Droid($scope) {

$scope.sell = function(newLocation) {

$scope.location = newLocation;

}

}

// html

<div ng-controller="Sandcrawler">

<p>Location: </p>

<button ng-click="move('Mos Eisley South')">Move</button>

<div ng-controller="Droid">

    <p>Location: </p>

    <button ng-click="sell('Owen Farm')">Sell</button>

</div>

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

//使用factory API创建服务instance

app.factory('instance', function(){

return {};

});

app.controller('MainCtrl', function($scope, instance) {

$scope.change = function() {

instance.name = $scope.test;

};

});

app.controller('sideCtrl', function($scope, instance) {

$scope.add = function() {

$scope.name = instance.name;

};

});

//html

<div ng-controller="MainCtrl">

<input type="text" ng-model="test" />

<div ng-click="change()">click me</div>
