调用方式说明：

入参介绍：opt： {
    text: opt.text || "加载中..",
    duration: opt.duration || 300,
    type: opt.type || ‘loading‘
}opt对象的参数字段：text，你需要显示提示的文字；duration，自动显示/隐藏 提示的时间间隔；type，提示类型 ‘loading‘ | ‘success‘ | ‘failed‘ 每个类型对应一种提示的样式

原型方法：

show() ,即显示提示；

show() ,隐藏提示；

autoHide() ,自动显示隐藏提示；

调用举例：

var fnotice = new FEerNotice({　　text: "加载中..",　　duration: 2000,　　type: "loading"})fnotice.autoHide()
