Question

app.factory('dataPassingService', function() {
var savedData = {};
function set(data) {
    savedData = data;
}
function get() {
    return savedData;
}

return {
    set: set,
    get: get
}
});

控制器1

$scope.text = '9';
     dataPassingService.set($scope.text);

控制器2

 $scope.mes = dataPassingService.get();
 alert("the scope is "+scope.mes);

我使用app.factory将$ scope.text从controller1传递到控制器2，它完美无缺。我想将更多的范围从controller1传递到controller2，例如我想通过$ scope.text =＆＃39; 9＆＃39;和scope.text1 =＆＃39; 10＆＃39;然后使用datapassingService.get（）将其带到controller2。提前感谢

您可以传入一个键来唯一标识每个不同的数据，例如：

app.factory('dataPassingService', function() {
    var savedData = {};

    function set(key, data) {
        savedData[key] = data;
    }

    function get(key) {
        return savedData[key];
    }

    return {
        set: set,
        get: get
    }
});

用法：

控制器1

$scope.text = '9';
dataPassingService.set("myKey", $scope.text);
dataPassingService.set("message", "foo");

控制器2

$scope.mes = dataPassingService.get("myKey");
$scope.message = dataPassingService.get("message");
alert("the scope is " + $scope.mes); // the scope is 9

在angularjs中传递多个变量？
