1.时间格式的转换，秒化成 hour minutes seconds

changeTime:function(seconds){

        var hour=Math.floor(seconds/3600);

        var minute=Math.floor((seconds%3600)/60);

        var second=(seconds%60);

        if(parseInt(hour) < 10) hour = "0" + hour;

        if(parseInt(minute) < 10) minute = "0" + minute;

        if(parseInt(second) < 10) second = "0" + second;

        var time = hour+"："+minute+"："+second;

        return time;

    }

var date = new Date();
