Question

我使用SetInterval();函数来显示时间，有时它停止它不是常规行为，它只是停止。以下是我的代码：

<script language="JavaScript">
    setInterval(settime, 1000);
 function settime() 
 {
    try
    {
        var curtime = new Date();
        var curhour = curtime.getHours();
        var curmin = curtime.getMinutes();
        var cursec = curtime.getSeconds();
        var time = "";
        if(curhour == 0) curhour = 12;
        time = (curhour > 12 ? curhour - 12 : curhour) + ":" +
             (curmin < 10 ? "0" : "") + curmin + ":" +
             (cursec < 10 ? "0" : "") + cursec + " " +
             (curhour > 12 ? "PM" : "AM");
        var currentTime = new Date()
        var month = currentTime.getMonth();
        var year = currentTime.getFullYear()
        var day = currentTime.getDay();
        var dayString = "";
        if(day == 0)
            dayString = "Sunday";
        if(day == 1)
            dayString = "Monday";
        if(day == 2)
            dayString = "Tuesday";
        if(day == 3)
            dayString = "Wednesday";
        if(day == 4)
            dayString = "Thursday";
        if(day == 5)
            dayString = "Friday";
        if(day == 6)
            dayString = "Saturday";
        var fullDate = day + "/" + month + "/" + year;
        document.date.clock.value = "Date : "+fullDate;
        document.date.clock1.value = "Time : " + time;
    }
    catch(err)
    {
        alert("Errorr from Function");
    }
}

当有setInterval();停止并重新开始时，有没有办法捕捉!!

setInterval是众所周知的问题。改为使用setTimeout的递归调用。
