Question

我正在使用localForage而我正在使用localforage.createInstance创建一堆不同的商店。

现在我需要迭代这些商店。我无法跟踪哪些商店被创建，所以我需要localForage给我一个商店列表，但我在API中找不到这样的东西。

这可能吗？

Answer 1

不幸的是，现在没有这样的东西。当前跟踪该请求的Here is the issue。

Answer 2

我不确定这是否是最好的方法，但是... github中的issue忘记了。

async function getStoreNames() {
//Create some stores with localforage
let store1 = await localforage.createInstance({
    name: "yourDBName",
    storeName: "store1"
});
let store2 = await localforage.createInstance({
    name: "yourDBName",
    storeName: "store2"
});
let store3 = await localforage.createInstance({
    name: "yourDBName",
    storeName: "store3"
});
await store1.setItem("aaa", "aaa")//add something on stores
await store2.setItem("bbb", "bbb")
await store3.setItem("ccc", "ccc")

//With store fully initialized (can be any in yourDBName) get the stores names, can be the blob test store.
//Filter names if needed.
let storeNames = Array.from(store1._dbInfo.db.objectStoreNames).filter(x => !x.startsWith("l"))
console.log(storeNames);
return storeNames;
}

getStoreNames()//Remember the store must be working

我如何迭代所有商店？
