/**
 * Created by carlos on 2015/5/19.
 * 1、Qalert 页面提示插件，可以传入对应参数修改提示的位置和css
 * 2、QloadingCover 页面加载提示插件。    $.QloadingCover.options 可以改变默认属性
 * 3、setPosition 方法可以单独调用可以设置对象的位置，注意是position:fixed
 * 4、Qmodal 页面弹出框插件，默认ios样式
 * 5、Q_confirm 确定提示，类似于js中的confirm
 * 6、Q_alert 提示，类似于js中的alert
 * 7、Qstorage 本地缓存方法
