javascript - Angularjs变量在 Controller 中获取http不可见

Question

Controller 中不可见的变量是否仅在 html 中可见？

app.controller('Ctrl', function ($scope, $http) {
    var request = $http({
        method: "get",
        url: "xxxxxx.php"
    })
    .success(function(gl){
        $scope.users = gl;    
    });

    // Initial  data
    var e =  request.users;
    $scope.chartData = [
        ['Coo',e],
    ];
});

Answer 1

在$http.success内部构造$scope.chartData，就像

var request = $http({
    method: "get",
    url: "xxxxxx.php"
})
.success(function (gl) {
    $scope.users = gl;

    //initialize your chartData here or 
    //if you have already defined chartData then just push the new object
    $scope.chartData = [['Coo', $scope.users], ];
});

// Initial  data

//this will not work because request is a promise object
/*var e = request.users;
$scope.chartData = [
        ['Coo', e],
];*/
