Add attribute to javascript function

Question

I have javascript function who need add position attribute on object.

function conv(data){
var result=[];
function dfs(node, parent) {
    for(var i in node){
        result.push({id:node[i].id,pid:parent});
        if (node[i]['children']) dfs(node[i]['children'],node[i]['id']);
    }
}
dfs(data, 0);
return result;
}

DEMO

So I got result = [{"id":1,"pid":0},{"id":4,"pid":1},{"id":2,"pid":0}]

Need add position something like:

[
{"id":1,"pid":0,"position":100}, // First root
{"id":4,"pid":1,"position":100}, // First sub root
{"id":5,"pid":1,"position":101}, // Second sub root
{"id":2,"pid":0,"position":101}, // Second root
{"id":3,"pid":0,"position":102}, // Third root
]

UPDATE

Position always starts from 100 so its var can be static.

Where does the value of position comes from, is it computed from the position on the tree ? — Benoit Blanchon

Without further information, it seems you just need to add the position to the object you push in the array:

result.push({id:node[i].id,pid:parent,position:position});
