好的,所以我在LocalStorage中存储了这样的JSON:
[{"pseudo":"Lucia","id":2},{"pseudo":"Romain","id":1}]
我搜索了如何删除一项,但只找到了这一点:
storage.removeItem(keyName);
但是,如果我错了,请纠正我,如果我这样做,如果我执行storage.removeItem(pseudo);它将删除keyName为“ pseudo”的所有值。
如何仅从json中删除
{"pseudo":"Romain","id":1}
并保留{"pseudo":"Lucia","id":2}
?谢谢。
最佳答案
localstorage仅支持字符串值,因此您需要解析数据。
var storedNames = JSON.parse(localStorage.getItem("keyName"));
// here you need to make a loop to find the index of item to delete
var indexToRemove = 1;
//remove item selected, second parameter is the number of items to delete
storedNames.slice(indexToRemove, 1);
// Put the object into storage
localStorage.setItem('keyName', JSON.stringify(storedNames));
