它只能工作一次。点击第二个按钮，没有任何结果。
如果我在budilnik或i_budilnik更改了var budilnik变量，则它甚至不会有效！
问题出在哪里？
<div>
<form name="alert">
<input type="text" name="hour" />
<input type="text" name="min" />
<input type="button" value="ok" onclick="budilnik(this.form)">
</form><font color=#660000 size=20 face=Tahoma><span id="hours"></span>
</div>
<script type="text/javascript">
function budilnik(form) {
budilnik = 1;
min = form.min.value;
hour = form.hour.value;
}
obj_hours = document.getElementById("hours");
function wr_hours() {
time = new Date();
time_min = time.getMinutes();
time_hours = time.getHours();
time_wr = ((time_hours < 10) ? "0" : "") + time_hours;
time_wr += ":";
time_wr += ((time_min < 10) ? "0" : "") + time_min;
time_wr = time_wr;
obj_hours.innerHTML = time_wr;
if (i_budilnik == 1) {
if (min == time_min) {
if (hour == time_hours) {
alert('welldone');
budilnik = 0;
}
}
}
}
wr_hours();
setInterval("wr_hours();", 1000);
</script>
答案 0 :(得分：2)
你调用函数wr_hours（）;只有一次...用onclick budilnik被调用，但那不会再次触及wr_hours。第一次运行代码时，因为页面已加载，但在此之后，使用onclick只会再次设置min和hour的值。
编辑：你不应该把你的表单称为“警告”，因为这是javascript中的保留字，对于变量min也是如此。另外：变量min和hour在函数budilnik中定义，但在此范围之外不知道。我还将变量budilnik重命名为全局变量justonce，以确保您可以在budilnik范围之外进行检查。我重写了一下你的代码：
<html>
<body>
<div>
<form name="frm">
<input type="text" name="hour" />
<input type="text" name="mins"/>
<input type="button" value="ok" onclick="justonce=1;">
</form>
<font color=#660000 size=20 face=Tahoma><span id="hours"></span></font>
</div>
</body>
</html>
<script type="text/javascript">
obj_hours=document.getElementById("hours");
justonce=0;
function wr_hours()
{
time=new Date();
time_min=time.getMinutes();
time_hours=time.getHours();
time_wr=((time_hours<10)?"0":"")+time_hours;
time_wr+=":";
time_wr+=((time_min<10)?"0":"")+time_min;
obj_hours.innerHTML=time_wr;
if (justonce==1 && frm.mins.value==time_min && frm.hour.value==time_hours) {
alert('welldone');
justonce=0;
}
}
setInterval("wr_hours();",1000);
</script>
顺便说一句，你的函数wr_hours可能会短得多：
function wr_hours()
{
time=new Date();
obj_hours.innerHTML=("%02d",time.getHours())+":"+("%02d",time.getMinutes());
if (justonce==1
&& frm.mins.value==time.getMinutes()
&& frm.hour.value==time.getHours()) {
alert('welldone');
justonce=0;
}
}

这个怎么样？
您无法在此代码中听到“闹钟”，因此您必须下载自己喜欢的声音，重写部分代码。
