我有一个项目，我在其中创建嵌套对象中的数据，并将其存储在数据库中时，我正在执行JSON.stringify。一切正常，但是当我想从数据库中获取相同的数据时，我需要json.parse，但是在此之后，我将其分配给vuex状态，因此我从原始数据中丢失了一些嵌套数据。
数据库中的数据：
[{"id":"1-368","name":"\tSolan","days":1,"daynights":2,"hotel":{"hotel_data":[{"id":1,"title":"hotel 1"}],"checkin":"","checkout":"","roomtype":""},"hotel2":{"hotel_data":[{"id":1,"title":"hotel 1"}],"checkin":"","checkout":"","roomtype":""},"specinst":"","mealplan":""},{"id":"2-54","name":"Dharamsala","days":"3","daynights":4,"hotel":{"hotel_data":[{"id":3,"title":"hotel3"}],"checkin":"","checkout":"","roomtype":""},"hotel2":{"hotel_data":[{"id":2,"title":"hotel 2"}],"checkin":"","checkout":"","roomtype":""},"specinst":"","mealplan":""}]
分配给vuex状态后的数据：
[{"id":"1-368","name":"\tSolan","days":1,"daynights":2,"hotel":{"hotel_data":"","checkin":"","checkout":"","roomtype":""},"hotel2":{"hotel_data":"","checkin":"","checkout":"","roomtype":""},"specinst":"","mealplan":"","date_from":"08 Jan 2020","date_to":"09 Jan 2020"},{"id":"2-54","name":"Dharamsala","days":"3","daynights":4,"hotel":{"hotel_data":"","checkin":"","checkout":"","roomtype":""},"hotel2":{"hotel_data":"","checkin":"","checkout":"","roomtype":""},"specinst":"","mealplan":"","date_from":"09 Jan 2020","date_to":"12 Jan 2020"}]
在上面的代码中，您可以注意到hotel_data是一个嵌套数组，但是在将其分配给vuex状态后看不到。
代码：
const mutations = {
setItem（state，item）{
state.item.tour_location=JSON.parse(item.tour_location);
}}
尝试将值的字符串化为JSON.parse(JSON.stringify(item.tour_location))换行
