问题描述
我有很多的麻烦这点，我似乎无法在这里找到任何东西SO或谷歌，可以帮助我发现我在做什么错
I'm having a lot of trouble with this and I can't seem to find anything here on SO or Google that helps me spot what I'm doing wrong
<!DOCTYPE html>
<html data-ng-app="testApp">
<head>
<title></title>
</head>
<body>
<div data-ng-controller="myController">
{{test}}<br/>
{{test2}}<br/>
{{test3}}
<ul>
<li data-ng-repeat="member in members">{{ member.firstname}}</li>
</ul>
</div>
<script type="text/javascript" src="angular.min.js"></script>
<script type="text/javascript">
angular.module('testApp', ['memberFactory']);
angular.module('testApp',[])
.factory('memberFactory', function($http){
var obj = {};
obj.data = "abcd";
obj.getResponse = function(){
var temp = {};
$http.get('hello.php').success(function(data){
alert(data);
temp =data;
});
return "some return value";
}
return obj
});
function myController($scope, memberFactory){
$scope.test= "testString";
$scope.test2= memberFactory.data;
$scope.test3= memberFactory.getResponse();
}
</script>
</body>
</html>
在回归一些返回值; 的作品，但是当我尝试返回临时，它的空。我曾尝试各种方式来得到这个工作，但我似乎无法设置 $ http.get（）函数内的临时值
the return "some return value"; works but when I try to return temp, its null. I have tried various ways to get this to work but I just can't seem to set the temp value inside the $http.get() function
这可能是一些简单的（或我的一个愚蠢的错误/误导的做法）。任何意见将大大AP preciated
It is probably something simple (or a silly mistake/misguided approach on my part). Any advice would be greatly appreciated
推荐答案
使用延迟：
obj.getResponse = function(){
var temp = {};
var defer = $q.defer();
$http.get('hello.php').success(function(data){
alert(data);
temp =data;
defer.resolve(data);
});
return defer.promise;
}
