    定义的时候写的weeekday 下面写的weekday

    getMinutes不是getMintues  = =

    多用F12有奇效哦~

    <script type="text/javascript">
    var attime;
    function clock(){
        //为里多写了一个e
        var weekday = ["星期日","星期一","星期二","星期三","星期四","星期五","星期六"]
        var time=new Date();
        //getMintues  应该是 getMinutes    字符串拼接两边都要有+
        attime=time.getHours()+":"+time.getMinutes()+":"+time.getSeconds()+weekday[time.getDay()];
        document.getElementById("clock").value = attime;
    }
    setInterval(clock,1000);
