Form.value 删除：null 和空值“”（Angular/TypesScript）

Question

I have a form.value like this...

{
  "id": 1,
  "first_name": "foo",
  "last_name": "",
  "xxxxx": null
}

I would like remove object null or empty ("").

{
  "id": 1,
  "first_name": "foo"
}

Thanks!

Tente isso ES6 / ES2015:

Object.keys(obj).forEach(k => (!obj[k] && obj[k] !== undefined) && delete obj[k]);
