This that only requires javascript and appears a little more readable than other answers   I assume when you write  value  you mean  id      your code var countries        countries results          id  AF  name  Afghanistan         id  AL  name  Albania         id  DZ  name  Algeria         solution    function to remove a value from the json array function removeItem obj  prop  val        var c  found false      for c in obj            if obj c  prop     val                found true              break                      if found           delete obj c             example  call the  remove  function to remove an item by id  removeItem countries results  id   AF       example2  call the  remove  function to remove an item by name  removeItem countries results  name   Albania        print our result to console to check it works   for c in countries results        console log countries results c  id

you can use delete operator to delete property by it s name  delete objectExpression property   or iterate through the object and find the value you need and delete it   for prop in Obj      if Obj hasOwnProperty prop          if Obj prop       myValue            delete Obj prop
