我想使用javascript提取后更改json格式

Question

1. 我有一個像下面這樣的json ..獲取此json后，我將其存儲在一個名為data的變量中。我需要將此數據變量更改為以下

     { "recipes": [ { "cuisine": "chinese", "description": "hjkhdkd", "id": 3, "min_time": "30-60min", "name": "Noodles", "nutrition": "", "qty": "", "quantity_unit_id": "2", "rate": "", "recipe_type": "vegetarian", "serve": [ "4" ], "tip": "", "image_url": { "medium": "/system/recipes/images/000/000/003/medium/dfdfs.jpeg?1501851554" } } ] } 

2. 我如何使用JavaScript更改上述像波紋管這樣的json數據

    [ { "cuisine": "chinese", "description": "hjkhdkd", "id": 3, "min_time": "30-60min", "name": "Noodles", "nutrition": "", "qty": "", "quantity_unit_id": "2", "rate": "", "recipe_type": "vegetarian", "serve": [ "4" ], "tip": "", "image_url": { "medium": "/system/recipes/images/000/000/003/medium/dfdfs.jpeg?1501851554" } } ] 

Answer 1

var data = '{ "recipes": [ { "cuisine": "chinese", "description": "hjkhdkd", "id": 3, "min_time": "30-60min", "name": "Noodles", "nutrition": "", "qty": "", "quantity_unit_id": "2", "rate": "", "recipe_type": "vegetarian", "serve": [ "4" ], "tip": "", "image_url": { "medium": "/system/recipes/images/000/000/003/medium/dfdfs.jpeg?1501851554" } } ] }';
var jsonifieddata = JSON.parse(data);
var newdata = jsonifieddata.recipes;
JSON.stringify(newdata);

在控制台中運行。
