如何设置的范围属性时，则可以通过角度的控制？ [英] How to set a property of scope in the controller when it is available in angular?

问题描述

我有一个全球性的JS对象称为实例_

I have a global JS object called instance_

它有一个叫做当前属性_

It has a property called current_

后来得到一个属性调用数据集_

Which later gets a property called dataset_

所以basicaly instance_.current_.dataset _

so basicaly instance_.current_.dataset_

我用这个dataset_属性在div来显示当前的数据集。但是，当控制器由角CURRENT_ initiliased为空。所以我不能使用CURRENT_的dataset_财产我不能设置 $ =范围_ instance_.current_.dataset 为当前_ 是空

I use this dataset_ property in a div to show current dataset. But when the controller is initiliased by angular current_ is null. So I cant use dataset_ property of current_ as I cant set $scope = instance_.current_.dataset_ascurrent_isnull

我该如何解决这个问题？

How do I solve this?

在解决方案的替代尝试，我怎么能延缓这种特殊的控制器的初始化，直到current_view_仍然空？

an alternative attempt at a solution, how can I delay this particular controller's initialization until current_view_ remains null?

推荐答案

这可能是一个解决方案。工厂添加到您的应用程序，如：

This may be one solution. Add a factory to your app, like this:

myApp = angular.module('myApp', []);
myApp.factory('myGlobalDataSet', function(){
    return instance_.current_.dataset_;
});

然后，工厂的值传递到控制器：

Then pass the factory's value into your controller:

function myController($scope, myGlobalDataSet) {
  $scope.myGlobalDataSet = myGlobalDataSet;
}

然后在视图里，你应该能够访问myGlobalDataSet变量。如果你用NG-模型比分扳成那么它应该与视图的详细信息，请全球价值进行绑定。

Then within your views you should be able to access the myGlobalDataSet variable. If you tie it with an ng-model then it should bind your global value with the details of the view.
