[javascript] 简单封装localStorge操作

//存储localStorge
function setLocalStorage(key,obj){
    if(!navigator.cookieEnabled||typeof window.localStorage == 'undefined'){
        return false;
    }
    localStorage.setItem(key, JSON.stringify(obj));
    return true;
}
//读取localStorge
function getLocalStorage(key){
    if(!navigator.cookieEnabled||typeof window.localStorage == 'undefined'){
        return false;
    }
    var str=localStorage.getItem(key);
    if(!str){
        return false;
    }
    return JSON.parse(str);
}
