Question

我是Angularjs的新手。我想发送两个GET查询以获取来自两个网址的响应，但我只能从第一个网址获得响应（显示在控制台的屏幕截图中），并且无法在网页上显示响应。

有人可以帮我解决这个问题吗？非常感谢。

Answer 1

试试这个：

var promises = [];
promises.push($http.get("url1"));
promises.push($http.get("url2"));

$q.all(promises).then(function (data){
    $scope.course = data[0];
    $scope.location = data[1];
}
