I wish to filter a nested javascript object by the value of the "step" key:
var data = {
"name": "Root",
"step": 1,
"id": "0.0",
"children": [
{
"name": "first level child 1",
"id": "0.1",
"step":2,
"children": [
{
"name": "second level child 1",
"id": "0.1.1",
"step": 3,
"children": [
{
"name": "third level child 1",
"id": "0.1.1.1",
"step": 4,
"children": []},
{
"name": "third level child 2",
"id": "0.1.1.2",
"step": 5,
"children": []}
]},
]}
]
};
var subdata = data.children.filter(function (d) {
return (d.step <= 2)});
This just returns the unmodified nested object, even if I put value of filter to 1.
does .filter work on nested objects or do I need to roll my own function here, advise and correct code appreciated.
