Javascript Object push function

Question

I have a javascript object  I actually get the data through an ajax request    var data         I have added some stuff into it   data 0       ID    1    Status    Valid    data 1       ID    2    Status    Invalid      Now I want to remove all objects with an invalid status  but keep everything the ordering same    var tempData       for   var index in data         if   data index  Status     Valid              tempData push  data            data   tempData    In my mind  all of this should work  but I am getting an error that tempData push is not a function   I understand why it isn t the same as an array  but what could I do otherwise

You must make var tempData   new Array     Push is an Array function

I assume that REALLY you get object from server and want to get object on output  Object keys data  map k  gt  data k  Status   Invalid   amp  amp  delete data k      x000D   x000D  var data     5     ID    0    Status    Valid          some OBJECT from server response x000D   x000D  data        data  x000D    0     ID    1    Status    Valid     x000D    1     ID    2    Status    Invalid     x000D    2     ID    3    Status    Valid    x000D    x000D   x000D     solution 1  where output is sorted filtred array x000D  let arr Object keys data  filter k  gt  data k  Status   Invalid   map k  gt data k   sort  a b   gt  a ID-b ID   x000D     x000D     solution2  where output is filtered object x000D  Object keys data  map k  gt  data k  Status   Invalid   amp  amp  delete data k   x000D     x000D     show x000D  console log  Object  data   x000D  console log  Array   arr   x000D   x000D   x000D

Objects does not support push property  but you can save it as well using the index as key    x000D   x000D  var tempData       x000D  for   var index in data     x000D    if   data index  Status     Valid       x000D      tempData index    data   x000D       x000D     x000D  data   tempData  x000D   x000D   x000D    I think this is easier if remove the object if its status is invalid  by doing    x000D   x000D  for var index in data   x000D    if data index  Status     Invalid     x000D      delete data index    x000D       x000D    x000D   x000D   x000D    And finally you don t need to create a var temp

tempData push  data index       I agree with the correct answer above  but     your still not giving the index value for the data that you want to add to tempData   Without the  index  value the whole array will be added

Javascript programming language supports functional programming paradigm so you can do easily with these codes   var data           Id    1    Status    Valid          Id    2    Status    Invalid      var isValid   function data       return data Status      Valid      var valids   data filter isValid

push   is for arrays  not objects  so use the right data structure   var data              data 0       ID    1    Status    Valid     data 1       ID    2    Status    Invalid            var tempData       for   var index 0  index lt data length  index           if   data index  Status     Valid              tempData push  data            data   tempData
