json - Javascript Object push() function

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?

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<data.length; index++ ) {
    if ( data[index].Status == "Valid" ) {
        tempData.push( data );
    }
}
data = tempData;
