我在做什么： 简单的html文件显示第一页，在这个页面我有一个标题和按钮，最初我设置$ scope.index = 0.所以，我们设置数组的第一个位置。当我们点击下一个按钮时，它会找到firstCtrl和first.html页面。在这个控制器中我更新$ scope.index 1.所以，我的问题是当我更新myCtrl的$ scope.index然后$ scope.index在另一个控制器上更改我想要更改myCtrl。可能吗 ？如果它是帮助我。
<body ng-controller="myCtrl">
<div id="navbar">
<div class="setToggle">
<input id="slide-sidebar" type="checkbox" role="button" />

在这个控制器中，当我们调用nextQuestion（）时，我会更新$ scope.index。这里$ scope.index增加1和$ watch函数也获得索引的最新值。但是myCtrl没有更新。我想更新myCtrl。
(function() {
var app = angular.module("app.controllers");
app.controller("sidebarCtrl", ['$scope', "$location", "Data", function($scope, $location, Data) {
$scope.inc = 0;
$scope.next = function() {
$scope.inc += 1;
}
$scope.prev = function() {
$scope.inc -= 1;
}
$scope.nextQuestion = function() {
$scope.index += 1;
$location.path("/question/2");
}
$scope.$watch('index', function (newValue, oldValue) {
console.log("SASAS", newValue)
if (newValue !== oldValue) Data.setIndex(newValue);
});
}]);
})();
(function() {
var app = angular.module("app.service", []);
app.service("surveyService", function($http) {
this.getData = function (callbackFunc) {
$http({
method: "GET",
data: {something: true},
contentType: 'application/json',
dataType: 'jsonp',
url: "http://localhost:8080/TheSanshaWorld/sfcms/fetch-survey-details"
}).success(function(data){
callbackFunc(data);
}).error(function(){
alert("error");
});
};
this.setData = function(value) {
if (confirm('Do you wanna to submit?')) {
$http.post("http://localhost:8080/TheSanshaWorld/sfcms/save-survey-result-data", value).success(function(data, status) {
window.open("../index.html","_self");
});
} else {
return false;
}
};
});
app.factory('Data', function () {
var data = {
Index: ''
};
return {
getIndex: function () {
return data.Index;
},
setIndex: function (index) {
data.Index = index;
console.log("service", data.Index)
}
};
});
})();

因为 sidebarCtrl 嵌套在 myCtrl 中，因此您可以从到达 myCtrl $ scope.index > sidebarCtrl 使用它 $ scope。$ parent.index ，
通过测试尝试：将任何参数值添加到myCtrl $ scope.name ='Bob'; 然后将其记录在sidebarCtrl console.log（$ scope。$ parent.name）;你应该看到打印'鲍勃'。对索引执行相同的操作。
