JS 获取时间

function CurentTime()
    {
        var now = new Date();
        var year = now.getFullYear();       //年
        var month = now.getMonth() + 1;     //月
        var day = now.getDate();            //日
        var hh = now.getHours();            //时
        var mm = now.getMinutes();          //分
        var clock = year + "-";
        if(month < 10)
            clock += "0";
        clock += month + "-";
        if(day < 10)
            clock += "0";
        clock += day + " ";
        if(hh < 10)
            clock += "0";
        clock += hh + ":";
        if (mm < 10) clock += '0';
        clock += mm;
        return(clock);
    }
    });
