顶级模态对话框，涵盖整个角度应用(top-level modal dialog to cover whole angular application)

 我想使用模态（来自angular-ui-bootstrap项目）实现登录对话框。 它应该覆盖整个应用程序，在背景中覆盖它，并且应该能够在AngularJS服务将变量设置为false时立即引发。 
 
 我不喜欢使用路由到登录页面，因为我想在应用程序中保留输入值。 
 
 你怎么能观察变量并正确触发模态对话框的open（）函数？ 
 
 编辑：我正在使用Thrift与服务器进行通信，因此在我的情况下，查看$ http状态代码通常并不容易...... 

i would like to implement a login dialog using a modal (from angular-ui-bootstrap project). It should lay over the whole application, cover it in the backdrop and should be able to be raised as soon as a AngularJS service sets a variable to false.
 
I don't like to use routing to a login page because i'd like to keep input values in the application.
 
How could you watch the variable and trigger the open()-function of the modal dialog properly?
 
EDIT: I'm using Thrift for communicating with the server, so watching for $http Status Codes is generally not easy in my case...
