h5存儲localStorage方法

用到搜索不免須要來存搜索記錄。這是localStorage的功能就顯而易見了

1.存搜索記錄

export const saveStorage = (key, data) => {
    try {
        var serializedState = JSON.stringify(data);//系列化對象。把對象的類型轉換爲字符串類型
        localStorage.setItem(key, serializedState);
    } catch (err) {
        //ignore errors.
    }
}

2.拿搜索記錄

export const loadStorage = (key) => {
    try {
        const serializedState = localStorage.getItem(key);
        if (serializedState === null) {
            return undefined;
        }
        return JSON.parse(serializedState);//json字符串轉換成對象
    } catch (err) {
        return undefined;
    }
}

 實例：

let hisTory = {AE:"三十歲"，MY:"55"，additional:"事實上"，brand:"CJ"，car_type:"k22",Value:"無驗證",state:"1",stateValue:"未開始"}

　　

saveStorage ('key',hisTory);//存
loadStorage（'key'）;//拿
