使用jqMobi开发app基础：HTML5 LocalStorage 本地存储详解手机开发

     在开发app时，会经常用到HTML5 LocalStorage 本地存储相关的资料。例如记住用户名，原来是使用cookie，现在基本都改成了LocalStorage 。

   使用LocalStorage 其实很简单，localStorage.setItem(key, value );设置值，localStorage.getItem(key)读取值。

    可以使用的代码：

LocalMobelInfo = function () { 
}; 
LocalMobelInfo.prototype.putStringData = function (key, value) { 
    localStorage.setItem(key, value + ""); 
}; 
LocalMobelInfo.prototype.putBooleanData = function (key, value) { 
    localStorage.setItem(key, value + ""); 
}; 
LocalMobelInfo.prototype.putIntData = function (key, value) { 
    localStorage.setItem(key, value + ""); 
}; 
LocalMobelInfo.prototype.updateUser = function (name) { 
    localStorage.setItem("USERNAME", name + "");   
} 
LocalMobelInfo.prototype.getBooleanData = function (key) { 
    return "true" == localStorage.getItem(key) ? true : false; 
}; 
LocalMobelInfo.prototype.getStringData = function (key) { 
    return localStorage.getItem(key); 
}; 
LocalMobelInfo.prototype.getIntData = function (key) { 
    if (!isNullOrUndefined(localStorage.getItem(key))) { 
        return parseInt(localStorage.getItem(key)); 
    } else { 
        return 0; 
    } 
}; 
LocalMobelInfo.prototype.getUserName = function () { 
    return localStorage.getItem("USERNAME"); 
}
