我创建了一个计时器,当计时器恰好到达下午 5:00/17:00 时,用作警报的参考。你有什么想法我该怎么做?我会不时查看时间吗?
这是我创建计时器的方法。
<script language="JavaScript">
var tick;
function stop() {
clearTimeout(tick);
}
function usnotime() {
var datetoday = document.getElementById("datenow")
var currentDate = new Date()
var day = currentDate.getDate()
var month = currentDate.getMonth() + 1
var year = currentDate.getFullYear()
datetoday.val("" + month + "/" + day + "/" + year + "");
var txt = document.getElementById("timeticker")
var ut = new Date();
var h, m, s;
var time = " ";
h = ut.getHours();
m = ut.getMinutes();
s = ut.getSeconds();
if (s <= 9) s = "0" + s;
if (m <= 9) m = "0" + m;
if (h <= 9) h = "0" + h;
time += h + ":" + m + ":" + s;
txt.innerHTML = time;
tick = setTimeout("usnotime()", 1000);
}
//--> document.rclock.rtime.value=time; tick=setTimeout("usnotime()",1000); } //-->
</script>
<tr>
<td class="tdlabel">Current Time:</td>
<td>
<div id="timeticker" name="rtime" size="22"></div>
</td>
</tr>
而且似乎我的计时器没有显示。有任何想法吗??
