Is it bad to declare ng-app and ng-controller on html tag?

Question

Is it bad practice to declare both ng-app and ng-controller on the tag?

For example:

Answer 1

I don't think there will be any problem so far. The only impact is the rootscope no more readable from html markup, because the controller scope is overriding it.

For example,

  


$rootScope.$id = 002    // rootscope from $rootscope service
$("#parent").scope().$id =002 // rootscope scope get from element scope    
$("#child").scope().$id =003  // controller scope get from element scope 

when it comes to the same markup,

$rootScope.$id = 002    // rootscope from $rootscope service
$("#parent").scope().$id =003 // controller scope get from element scope

Here you have no way to get rootscope from element scope, but who cares.
