        var hour= myDate.getHours()<10?"0"+myDate.getHours():myDate.getHours();// myDate.getHours();       //获取当前小时数(0-23)
        var minutes=  myDate.getMinutes()<10?"0"+myDate.getMinutes():myDate.getMinutes();//myDate.getMinutes();     //获取当前分钟数(0-59)
        var seconds=  myDate.getSeconds()<10?"0"+myDate.getSeconds():myDate.getSeconds();// myDate.getSeconds();     //获取当前秒数(0-59)
