javascript - 无论如何都可以在没有设置器和获取器的情况下从角度服务设置和获取数据？

Question

我想使用在控制器的相同实例之间共享的服务，但我不想为每个属性创建设置器和获取器，角度是否提供了便利？这是我想逃避的一个例子：

app.service('YtPlayerService', function(){
    this.playerStatus = {
        status  : 'alert',
        text    : 'Loading The Player'
    };
});

app.controller("YtPlayerController", function($scope,YtPlayerService){
    $scope.playerStatus = function(){
        return YtPlayerService.playerStatus;
    }

    $scope.setPlayerStatus = function(playerStatus){
        YtPlayerService.playerStatus = playerStatus;        
    };
}

您可以以编程方式生成它们以使其更容易忍受：

function generateAccessors( obj, propertyNames ) {
    for( var i = 0, len = propertyNames.length; i < len; ++i ) {
        var propertyName = propertyNames[i],
            camelCased = propertyName.charAt(0).toUpperCase() + propertyName.substr(1);
        obj[ "get" + camelCased ] = (function(propertyName){
            return function() {
                return obj[propertyName];
            };

        })(propertyName);
        obj[ "set" + camelCased ] = (function(propertyName){
            return function( value ) {
                obj[propertyName] = value ;
            };
        })(propertyName);
    }
}

这种情况下的用法是：

app.service('YtPlayerService', function(){
    this.playerStatus = {
        status  : 'alert',
        text    : 'Loading The Player'
    };
    generateAccessors( this, ["playerStatus"] );
});

另一个例子

var obj = {};
generateAccessors( obj, ["playerStatus", "name"]);
obj.setName(3);
obj.getName(); //3
