我要評論本文給大家分享的是使用CSS3結合js實現(xiàn)簡單的時鐘特效的代碼，主要是使用了css3 的transform屬性中的 rotate的旋轉效果和translate的位移效果的，這里推薦給大家，希望大家能夠喜歡。
學習css3ing，正在學習transfomr，突發(fā)奇想用此做個小時鐘，開始吧：
準備前期工作，把時鐘的表盤，時分秒針，實時時間標簽 的大概樣子做好，效果如圖：
html代碼如下：
復制代碼
代碼如下:<div class="main">
<div id="timeLabel"></div>
<div id="hour"></div>
<div id="minute"></div>
<div id="second"></div>
</div>
css 代碼如下：
復制代碼
代碼如下:<style>
* {
margin: 0;
padding: 0;
}
.main {
position: relative;
margin: 100px auto;
width: 300px;
height: 300px;
border-radius: 300px;
border: 1px solid #000;
box-shadow:2px 5px;
}
#timeLabel {
position: absolute;
background-color:pink;
width:100px;
height:30px;
left:100px;
top:180px;
}
#hour {
width: 100px;
height: 10px;
background-color: red;
position:absolute;
left:150px;
top:145px;
}
#minute {
width:120px;
height:8px;
background-color:blue;
position:absolute;
left:150px;
top:146px;
}
#second {
width: 140px;
height: 4px;
background-color: green;
position: absolute;
left: 150px;
top: 148px;
}
</style>
2. 初始化默認時間，和表盤刻度 ，效果如下：
更改后的css代碼：
復制代碼
代碼如下:<style>
* {
margin: 0;
padding: 0;
}
.main {
position: relative;
margin: 100px auto;
width: 300px;
height: 300px;
border-radius: 300px;
border: 1px solid #000;
box-shadow: 2px 5px #808080;
}
#timeLabel {
position: absolute;
background-color: pink;
width: 80px;
height: 25px;
left: 110px;
top: 180px;
color: #fff;
line-height: 25px;
text-align: center;
}
#hour {
width: 100px;
height: 10px;
background-color: red;
position: absolute;
left: 150px;
top: 145px;
transform-origin: 0 50%;
}
#minute {
width: 120px;
height: 8px;
background-color: blue;
position: absolute;
left: 150px;
top: 146px;
transform-origin: 0 50%;
}
#second {
width: 140px;
height: 4px;
background-color: green;
position: absolute;
left: 150px;
top: 148px;
transform-origin: 0 50%;
}
.hourPointer, .minuterPointer, .secondPointer {
position: absolute;
transform-origin: 0 50%;
}
.hourPointer {
height: 10px;
width: 12px;
left: 150px;
top: 145px;
background-color: #f00;
z-index:3;
}
.minuterPointer {
height: 8px;
width: 10px;
left: 150px;
top: 146px;
background-color: #b6ff00;
z-index: 2;
}
.secondPointer {
height: 6px;
width: 8px;
left: 150px;
top: 147px;
background-color: #fa8;
z-index: 1;
}
</style>
初始化 js代碼：
復制代碼
代碼如下:window.onload = function () {
initClock();
}
var timer = null;
function $(id) {
return document.getElementById(id)
}
function CreateKeDu(pElement, className, deg, translateWidth) {
var Pointer = document.createElement("div");
Pointer.className = className
Pointer.style.transform = "rotate(" + deg + "deg) translate(" + translateWidth + "px)";
pElement.appendChild(Pointer);
}
function initClock() {
var main = $("biaopan");
var timeLabel = $("timeLabel");
var hour = $("hour");
var minute = $("minute");
var second = $("second");
var now = new Date();
var nowHour = now.getHours();
var nowMinute = now.getMinutes();
var nowSecond = now.getSeconds();
//初始化timeLabel
timeLabel.innerHTML = nowHour + ":" + nowMinute + ":" + nowSecond;
//初始化表盤
for (var index = 0; index < 4; index++) {
CreateKeDu(main, "hourPointer", index * 90, 138);
}
for (var index = 0; index < 12; index++) {
CreateKeDu(main, "minuterPointer",index*30, 140);
}
for (var index = 0; index < 60; index++) {
CreateKeDu(main, "secondPointer", index * 6, 142);
}
//初始化時分秒針
second.style.transform = "rotate(" + (nowSecond * 6 - 90) + "deg)";
minute.style.transform = "rotate(" + (nowMinute * 6 + 1 / 10 * nowSecond - 90) + "deg)";
hour.style.transform = "rotate(" + (nowHour * 30 + 1 / 2 * nowMinute + 1 / 120 * nowSecond - 90) + "deg)";
}
3.添加定時器：
js代碼如下：
復制代碼
代碼如下://定時器
function startMove() {
clearInterval(timer);
timer = setInterval(function () {
var now = new Date();
var nowSecond = now.getSeconds();
var nowMinute = now.getMinutes();
var nowHour = now.getHours();
second.style.transform = "rotate(" + (nowSecond * 6 - 90) + "deg)";
minute.style.transform = "rotate(" + (nowMinute * 6 + 1 / 10 * nowSecond - 90) + "deg)";
hour.style.transform = "rotate(" + (nowHour * 30 + 1 / 2 * nowMinute + 1 / 120 * nowSecond - 90) + "deg)";
timeLabel.innerHTML = nowHour + ":" + nowMinute + ":" + nowSecond;
}, 1000);
}
4.使用OOP方式更改：
修改后的js代碼如下：
復制代碼
代碼如下:function Clock() {
//定義屬性
this.main = this.$("biaopan");
this.timeLabel = this.$("timeLabel");
this.hour = this.$("hour");
this.minute = this.$("minute");
this.second = this.$("second");
this.nowHour = null;
this.nowMinute = null;
this.nowSecond = null;
this.timer = null;
var _this = this;
//初始化函數(shù)
var init = function () {
_this.getNowTime();
_this.initClock();
_this.InterVal();
}
init();
}
Clock.prototype.$ = function (id) {
return document.getElementById(id)
}
Clock.prototype.CreateKeDu = function (className, deg, translateWidth) {
var Pointer = document.createElement("div");
Pointer.className = className
Pointer.style.transform = "rotate(" + deg + "deg) translate(" + translateWidth + "px)";
this.main.appendChild(Pointer);
}
Clock.prototype.getNowTime = function () {
var now = new Date();
this.nowHour = now.getHours();
this.nowMinute = now.getMinutes();
this.nowSecond = now.getSeconds();
}
Clock.prototype.setPosition = function () {
this.second.style.transform = "rotate(" + (this.nowSecond * 6 - 90) + "deg)";
this.minute.style.transform = "rotate(" + (this.nowMinute * 6 + 1 / 10 * this.nowSecond - 90) + "deg)";
this.hour.style.transform = "rotate(" + (this.nowHour * 30 + 1 / 2 * this.nowMinute + 1 / 120 * this.nowSecond - 90) + "deg)";
}
Clock.prototype.initClock = function () {
//初始化timeLabel
this.timeLabel.innerHTML = this.nowHour + ":" + this.nowMinute + ":" + this.nowSecond;
//初始化表盤
for (var index = 0; index < 4; index++) {
this.CreateKeDu("hourPointer", index * 90, 138);
}
for (var index = 0; index < 12; index++) {
this.CreateKeDu("minuterPointer", index * 30, 140);
}
for (var index = 0; index < 60; index++) {
this.CreateKeDu("secondPointer", index * 6, 142);
}
this.setPosition();
}
Clock.prototype.InterVal = function () {
clearInterval(this.timer);
var _this = this;
this.timer = setInterval(function () {
_this.getNowTime();
_this.second.style.transform = "rotate(" + (_this.nowSecond * 6 - 90) + "deg)";
_this.minute.style.transform = "rotate(" + (_this.nowMinute * 6 + 1 / 10 * _this.nowSecond - 90) + "deg)";
_this.hour.style.transform = "rotate(" + (_this.nowHour * 30 + 1 / 2 * _this.nowMinute + 1 / 120 * _this.nowSecond - 90) + "deg)";
_this.timeLabel.innerHTML = _this.nowHour + ":" + _this.nowMinute + ":" + _this.nowSecond;
}, 1000);
}
最后調用如下：
復制代碼
代碼如下:window.onload = function () {
new Clock();
}
最終頁面代碼：
復制代碼
代碼如下:<!DOCTYPE html>
<html xmlns="<a >

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title></title>

background-color: #f00;
z-index: 3;
}
