实践|制作一个数码时钟（时间与日期切换）
329 查看--------正常显示时间的时分秒，当鼠标移上去的时候，切换成年月日---------
如下是动态示意图：
数码时钟主要特色：
1. 简洁
2. 金属色彩
3. setInterval()-->定时器
4. 运用事件onmouseover()和onmouseout()，使时间与日期之间自如切换
5. 个人能力有限，还望大家一起修改，使之更加完善一些问题：
各个浏览器的显示不是很理想，我已经想尽各种办法，使之平稳展现；
1. 火狐-->进行事件切换时，浮度比较大；
2. 谷歌-->完美运行(去掉某些样式）；
3. IE-->除了最新的，其他的不敢多想；只显示时分秒的JS代码：
<script type="text/javascript">
window.onload = function() {
var imgs = document.getElementsByTagName("img");
function checkTime(x) {
if(x<10) return "0" + x;
else return "" + x;
}
function oShowTime() {
var oDate = new Date();
var oHou = oDate.getHours();
var oMin = oDate.getMinutes();
var oSec = oDate.getSeconds();
var str = checkTime(oHou) + checkTime(oMin) + checkTime(oSec);
for (var i=0; i<imgs.length; i++) {
imgs[i].src = "images/" + str[i] + ".JPG";
}
}
setInterval(oShowTime, 1000);
oShowTime();
};
</script>
时间与日期事件切换的JS代码：
<script type="text/javascript">
window.onload = function() {
var oDiv = document.getElementById("div1");
var imgs = document.getElementsByTagName("img");
var timer = null;
/*判断获取到的数字是否小于10*/
function checkTime(x) {
if(x<10) return "0" + x;
else return "" + x;
}
/*鼠标点击事件*/
oDiv.onmouseover = function() {
clearInterval(timer);
fnDate();
};
oDiv.onmouseout = function() {
clearInterval(timer);
fnTime();
};
/*获取的日期函数*/
function fnDate() {
function oShowDate() {
var oDate = new Date();
var oYea = oDate.getFullYear();
oYea = oYea.toString();
var oMon = oDate.getMonth()+1;
var oDay = oDate.getDay();
var str = oYea.substr(2,2) + checkTime(oMon) + checkTime(oDay);
var aPar = document.getElementsByTagName("p");
for (var i=0; i<imgs.length; i++) {
imgs[i].src = "images/" + str[i] + ".JPG";
}
for (var j=0; j<aPar.length; j++) {
aPar[j].innerHTML = "-";
}
}
timer = setInterval(oShowDate, 1000);
oShowDate();
}
/*获取的时间函数*/
function fnTime() {
function oShowTime() {
var oDate = new Date();
var oHou = oDate.getHours();
var oMin = oDate.getMinutes();
var oSec = oDate.getSeconds();
var str = checkTime(oHou) + checkTime(oMin) + checkTime(oSec);
var aPar = document.getElementsByTagName("p");
for (var i=0; i<imgs.length; i++) {
imgs[i].src = "images/" + str[i] + ".JPG";
}
for (var j=0; j<aPar.length; j++) {
aPar[j].innerHTML = ":";
}
}
timer = setInterval(oShowTime, 1000);
oShowTime();
}
fnTime();
};
</script>css样式设置：
<style type="text/css">
body {
background-color: #333;
font-size: 80px;
}
#div1 {
width: 600px;
height: 180px;
border: 40px solid #999;
border-radius: 60px;
box-shadow: 10px 14px 12px #777;
margin: 150px auto;
background-color: #FFF;
}
.div2 {
width: 580px;
height: 160px;

padding-left: 9px; /*谷歌浏览器不用设置*/
}

p {
