My question goes like this. I have a JSON object below. I want to remove the object that has an assignment 1. I already looped through it and by the best of me I cannot seem to remove that particular object.



0: Object

  teller_id: 1

  details: CASH

  assignments: Array [2]

   0: Object  <---- Remove this Object and all the elements indside it

      service_id: 1

      status: 1

      assignment: 1

   1: Object

      service_id: 1

      status: 1

      assignment: 2

1: Object

 teller_id: 2

 details: EMP

 assignments: Array [2]

   0: Object

      service_id: 2

      status: 3

      assignment: 4

   1: Object

      service_id: 2

      status: 4

      assignment: 6


Remove object with an assignment of 1



0: Object

  teller_id: 1

  details: CASH

  assignments: Array [2]

   1: Object

      service_id: 1

      status: 1

      assignment: 2

1: Object

 teller_id: 2

 details: EMP

 assignments: Array [2]

   0: Object

      service_id: 2

      status: 3

      assignment: 4

   1: Object

      service_id: 2

      status: 4

      assignment: 6


In which it removes the Object[0] found inside the assignments array. Thanks

None of this really needs Angular, because it involves pure JavaScript.



In each object, assignments is an array. Whilst an array is a form of object, it has its own properties. There are a few ways to approach this.



Firstly if you wish to treat it as an array, then:



myObject[0].assignments.splice(0,1); // remove first element from array


or:



myObject[0].assignments.shift(); // get first element from array


This will however move the indexes of the assignments down in the array. i.e. assignments[1] will become assignments[0].



If you don't want to change the indices, then delete is what you're looking for:



delete myObject[0].assignments[0];


This will however cause the first element of the array to have the value undefined.
