angular dynamic (json chain) variables in ctrl variable definitions

Question

Do you know how to use dynamic/chained variables inside a controller variable definition?

I have created this plnkr to further outline what I am trying to achieve: http://plnkr.co/edit/xOjhf8b7ZIxVhc1Id3xo

In the NodeCtrl, I am trying to dynamically access a node from a json object and I can't find the correct syntax to write out the chain.

I have tried a number of combinations but haven't found the correct way yet:

  //var jsonChunk = "data." + $scope.transcendType;
    $scope.tabinventory =  data.$scope.transcendType; 
                         //data;
                         //jsonChunk; 
                         //function() { return "data." + $scope.transcendType; };
    alert($tabinventory[0].title)
  //alert($scope.tabinventory.project[0].title);

Any help you could provide would be greatly appreciated.

All the best,

Ben

data within success handler is the object represented by your JSON. It has no property $scope nor any property transcendType so very hard to figure out what you are trying to get. Also demo throws errors from undefined function scope.getNodeByID — charlietfl

Using [ ] as my "index" was what was throwing me: plnkr.co/edit/2oHBuJUi1FWmiugy0nrr?p=preview — Benjamin McFerren

Have you tried logging $scope.transcendType to make sure it's properly defined in that context?

Assuming it's properly defined, try data[$scope.transcendType].

I always post results back to Stack. I like to help people live & they like it too, then everyone gets to see the result. Win-win-win!

that;s irrelevant... not proper to post contact info here, or solicit direct contact...use profile for that and use chat system if need to

So you're advocating a worse user experience just to strictly follow the rules? Consider a career in law enforcement ;)
