Binding inputs to an array of primitives using ngRepeat => uneditable inputs

Question

Here is a demo to my problem.

$scope.myNumbers = [10, 20, 30];


    
         


        
      

Answer 1

ngRepeat uses a reference to the source array. Since integer (Number in js) is a value type, not a reference type, therefore cannot be passed by reference in javascript. The change will not be propagated.

Here is a demonstration:

   var x = 10;
   var ox = {value:10};

   var y = x;
   var oy = ox;

   y = 15
   oy.value = 15;

What would be the values of x and ox?

>> x = 10;
>> y = 15;
>> ox = {value:15};
>> oy = {value:15};

All javascript objects are passed by reference and all primitives are passed by value ["string", "number", etc].
