如何在javascript

Question

我想在每个换行符上添加'\ n'。可以使用reg表达来实现

 {
  "name": " ",
  "type": "column",
  "axis": "vertical",
  "content_type": "stack_view",
  "contents": [
    {
      "name": "",
      "type": "row",
      "axis": "horizontal",
      "content_type": "field",
      "contents": [],
      "isParentBlock": false,
      "weight": 100
    }
  ],
  "isParentBlock": true,
  "weight": 100
}

PS-我想实现以下目标。
