所以我在使用 firebase 刪除項目后嘗試更新 json .delete()。這是json刪除前"data": [ { "position": "3", "name": "foo" }, { "name": "bar", "position": "1" }, { "name": "deleteMe", "position": "2" }, { "name": "somethingElse", "position": "4" }]這是之后："data": [ { "position": "3", "name": "foo" }, { "name": "bar", "position": "1" }, { "name": "somethingElse", "position": "4" }]現在我所要做的就是重新排序foo和somethingElse項目位置從#3到#2和#4到#3。我怎樣才能做到這一點？編輯：這是我想要的輸出："data": [ { "position": "2", "name": "foo" }, { "name": "bar", "position": "1" }, { "name": "somethingElse", "position": "3" }]
從 json 中刪除項目并編輯剩余項目 - nodejs/firebase 函數
