我正在尝试使用indexedDB存储一些应用程序数据

"这是我的密码"

function _getLocalApplicationCache(_, payload) {
const indexedDB = window.indexedDB || window.mozIndexedDB || window.webkitIndexedDB || window.shimIndexedDB;
if (!indexedDB) {
    if (__DEV__) {
        console.error("IndexedDB could not found in this browser.");
    }
}

const request = indexedDB.open("ApplicationCache", 1);
request.onerror = event => {
    if (__DEV__) {
        console.error("An error occurred with IndexedDB.");
        console.error(event);
    }
    return;
};

request.onupgradeneeded = function () {
    const db = request.result;
    const store = db.createObjectStore("swimlane", {keyPath: "id", autoIncrement: true});
    store.createIndex("keyData", ["name"], {unique: false});
};

request.onsuccess = () => {
    // creating the transition
    const db = request.result;
    const transition = db.transaction("swimlane", "readwrite");

    // Reference to our object store that holds the swimlane data;
    const store = transition.objectStore("swimlane");
    const swimlaneData = store.index("keyData");

    payload = JSON.parse(JSON.stringify(payload));
    store.put(payload);

    const Query = swimlaneData.getAll(["keyData"]);

    Query.onsuccess = () => {
        if (__DEV__) {
            console.log("Application Cache is loaded", Query.result);
        }
    };
    transition.oncomplete = () => {
        db.close();
    };
};

}

**如果我使用不同的版本，那么1在这里--〉indexedDB.open（“应用程序缓存”，1）;**我得到了一个错误，好像keyPath已经存在。除了版本1之外，我得到了这个错误。
