I have json response and I want to remove few object key values from it and store the edited response on other part so that I can use again.
I know by using simple javascript, but I don't have any idea in angularjs.
{
"$id": "1",
"XYZ": [],
"ABC": [
{
"$id": "41",
"ID": 1,
"Order": 0,
"Delay": 0,
"Name": "abc",
"Count": "9",
"Storage": 3,
"Groups": []
}
],
"Projected": 2019
}
Now from this Json file I want to filter out
"$id": "41"
, "ID": 1
, "Order": 0
, "Delay": 0
, "Groups": []
, "Name": "abc"
So my new json structure will be like this which I want to store:
{
"$id": "1",
"XYZ": [],
"ABC": [
{
"Count": "9",
"Storage": 3
}
],
"Projected": 2019
}
Any method to achieve ?
You don't need some magic angular stuff. You can just use plain old JavaScript. My apporach iterates through all the items in the ABC
array and delete
s all properties defined in the props
array. Note, that this actively modifies the ABC
array items.
const obj = { "$id": "1", "XYZ": [], "ABC": [ { "$id": "41", "ID": 1, "Order": 0, "Delay": 0, "Name": "abc", "Count": "9", "Storage": 3, "Groups": [] } ], "Projected": 2019 } // Now from this Json file I want to filter out const props = ["$id", "ID", "Order", "Delay", "Groups", "Name"]; props.forEach(prop => { obj.ABC.forEach(abc => { delete abc[prop]; }); }); console.log(obj);
try this
let json = { "$id": "1", "XYZ": [], "ABC": [ { "$id": "41", "ID": 1, "Order": 0, "Delay": 0, "Name": "abc", "Count": "9", "Storage": 3, "Groups": [] } ], "Projected": 2019 }; json["ABC"] = json["ABC"].map(obj => ({ "Count": obj["Count"], "Storage": obj["Storage"] })); // or dynamic way let keepkeys = ["Storage", "Count"]; json["ABC"] = json["ABC"].map(obj => { let newObj = {}; keepkeys.forEach(key => newObj[key] = obj[key]); return newObj; }); console.log(json)
An alternative to the other solutions. If we have a variable called json. This method is simple
let len = json.ABC.length;
for (let i=0;i<len;i++){
delete json.ABC[i].$id;
delete json.ABC[i].ID;
delete json.ABC[i].Order;
delete json.ABC[i].Delay;
delete json.ABC[i].Groups;
delete json.ABC[i].Name;
}
