页面重新加载时本地存储中的数据丢失

// 存储数据到localStorage
localStorage.setItem('myDataKey', JSON.stringify(myData));

// 从localStorage读取数据
const myData = JSON.parse(localStorage.getItem('myDataKey'));

function checkLocalStorageSpace() {
    let data = '';
    try {
        while (true) {
            data += '1234567890';
            localStorage.setItem('testSize', data);
        }
    } catch (e) {
        localStorage.removeItem('testSize');
        console.log('剩余空间：', data.length);
    }
}

// 确保在存储前数据是有效的
if (typeof myData === 'object') {
    localStorage.setItem('myDataKey', JSON.stringify(myData));
} else {
    console.error('无效的数据类型');
}

// 确保在读取后正确解析数据
const storedData = localStorage.getItem('myDataKey');
if (storedData) {
    try {
        const parsedData = JSON.parse(storedData);
        console.log(parsedData);
    } catch (e) {
        console.error('解析存储数据时出错:', e);
    }
