I have a json String coming in which looks like:

"Action" : "0876"

I am getting this using the expression

{{submenu1.Action}}

What I want can be summarised as :

  • Step 1: Parse and get the final element "6" from "0876" into a variable substr
  • Step 2: Casting/converting this substr into a number
  • Step 3: Use this as a pointer like Topmenu.number

I am looking for a solution specific to AngularJS. Any help is appreciated.

Why do you think string parsing has anything to do with AngularJS? Why don't you try using the substring function? developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/… –  JB Nizet 16 mins ago

In your controller you can do something as this:

function YourController($scope) {
   $scope.Action = "0876";

   // topmenu object for view
   $scope.Topmenu = { };

   // get last character in string and convert it to a number
   $scope.Topmenu.number = +$scope.Action.slice(-1);
}

Now the number 6 is available on your view as 

{{ Topmenu.number }}

Note: if you try to convert an empty string to a number you'll get 0, if you don't want this behaviour you'll need to add a check before converting

Topmenu is something i already have in the view. It got some contents which can be accessed using Topmenu.index. Where index is a number. And that number should be this 6. You may edit your answer accordingly.Thanks for the help. Also what if I want the entire string after the 1st element or second element as number? can I still use slice? –  RBz just now
