从REST-API $scope获取值后，不会更新视图
这是我的 HTML
<div ng-repeat="s in services1">
<label class="checkbox-inline">
<input type="checkbox" id="{{s.Id}}" name="{{s.Id}}" ng-model="s.IsChecked">
{{s.Name}}</label>
<br/>
</div>
AngularJS控制器
var addMember = [
'$scope', '$http', function ($scope, $http) {
$scope.member = [];
$scope.services1 = [];
var bid = "";
//onclick function
$scope.setId = function(id) {
$("#processing-modal").modal('show');
$http.get('/api/Servicesapi/ServicesByBusiness/' + id)
.then(function (response) {
$scope.services1 = response.data;
$("#processing-modal").modal('hide');
$("#anm").modal('show');
console.log($scope.services1); //this is printing values
},
function() {
alert("Error in getting services of this Employee");
});
console.log($scope.services1); //this prints empty array
};
}
];
第一个console.log()打印带有值的数组，但是$http.get函数外的另一个打印空括号并且视图未更新
更新

答案 0 :(得分：5)
<强>更新 我复制了两个同名的控制器声明。
<div ng-controller="addMember">
<button ng-click="setId()">SDFS</button>
</div>
<div ng-controller="addMember">
<p ng-repeat="s in services">{{s}}</p>
</div>
ng-repeat在第二个控制器声明中不起作用。如果我将<p ng-repeat="s in services">{{s}}</p>移动到顶级控制器，它可以工作。不要使用一个名称声明两个控制器：）

console.log($scope.services1); //this prints empty array
这是因为$ http.get（）承诺尚未解决。
试试此代码
var addMember = [
'$scope', '$http', '$timeout', function ($scope, $http, $timeout) {
$scope.member = [];
$scope.services1 = [];
var bid = "";
//onclick function
$scope.setId = function(id) {
$("#processing-modal").modal('show');
$http.get('/api/Servicesapi/ServicesByBusiness/' + id)
.then(function (response) {
$timeout(function(){
$scope.services1 = response.data;
});
$("#processing-modal").modal('hide');
$("#anm").modal('show');
console.log($scope.services1); //this is printing values
},
function() {
alert("Error in getting services of this Employee");
});
console.log($scope.services1); //this prints empty array
};
}
];
或在$scope.$apply()
$scope.services1 = response.data;
$scope.services1 = response.data;
$scope.$apply()
