小編給大家分享一下CSS3+js如何實(shí)現(xiàn)簡(jiǎn)單的時(shí)鐘特效,希望大家閱讀完這篇文章之后都有所收獲,下面讓我們一起去探討吧!
我們注重客戶(hù)提出的每個(gè)要求,我們充分考慮每一個(gè)細(xì)節(jié),我們積極的做好成都網(wǎng)站制作、成都做網(wǎng)站、外貿(mào)營(yíng)銷(xiāo)網(wǎng)站建設(shè)服務(wù),我們努力開(kāi)拓更好的視野,通過(guò)不懈的努力,創(chuàng)新互聯(lián)建站贏得了業(yè)內(nèi)的良好聲譽(yù),這一切,也不斷的激勵(lì)著我們更好的服務(wù)客戶(hù)。 主要業(yè)務(wù):網(wǎng)站建設(shè),網(wǎng)站制作,網(wǎng)站設(shè)計(jì),微信小程序開(kāi)發(fā),網(wǎng)站開(kāi)發(fā),技術(shù)開(kāi)發(fā)實(shí)力,DIV+CSS,PHP及ASP,ASP.Net,SQL數(shù)據(jù)庫(kù)的技術(shù)開(kāi)發(fā)工程師。css是一種用來(lái)表現(xiàn)HTML或XML等文件樣式的計(jì)算機(jī)語(yǔ)言,主要是用來(lái)設(shè)計(jì)網(wǎng)頁(yè)的樣式,使網(wǎng)頁(yè)更加美化。它也是一種定義樣式結(jié)構(gòu)如字體、顏色、位置等的語(yǔ)言,并且css樣式可以直接存儲(chǔ)于HTML網(wǎng)頁(yè)或者單獨(dú)的樣式單文件中,而樣式規(guī)則的優(yōu)先級(jí)由css根據(jù)這個(gè)層次結(jié)構(gòu)決定,從而實(shí)現(xiàn)級(jí)聯(lián)效果,發(fā)展至今,css不僅能裝飾網(wǎng)頁(yè),也可以配合各種腳本對(duì)于網(wǎng)頁(yè)進(jìn)行格式化。
學(xué)習(xí)css3ing,正在學(xué)習(xí)transfomr,突發(fā)奇想用此做個(gè)小時(shí)鐘,開(kāi)始吧:
準(zhǔn)備前期工作,把時(shí)鐘的表盤(pán),時(shí)分秒針,實(shí)時(shí)時(shí)間標(biāo)簽 的大概樣子做好,效果如圖:
html代碼如下:
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:
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(rèn)時(shí)間,和表盤(pán)刻度 ,效果如下:
更改后的css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:
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 = $("second");
var now = new Date();
var nowHour = now.getHours();
var nowMinute = now.getMinutes();
var nowSecond = now.getSeconds();
//初始化timeLabel
timeLabel.innerHTML = nowHour + ":" + nowMinute + ":" + nowSecond;
//初始化表盤(pán)
for (var index = 0; index < 4; index++) {
CreateKeDu(main, "hourPointer", index * 90, 138);
}
for (var index = 0; index < 12; index++) {
CreateKeDu(main, "minuterPointer",index*30, 140);
}
for (var index = 0; index < 60; index++) {
CreateKeDu(main, "secondPointer", index * 6, 142);
}
//初始化時(shí)分秒針
second.style.transform = "rotate(" + (nowSecond * 6 - 90) + "deg)";
minute.style.transform = "rotate(" + (nowMinute * 6 + 1 / 10 * nowSecond - 90) + "deg)";
hour.style.transform = "rotate(" + (nowHour * 30 + 1 / 2 * nowMinute + 1 / 120 * nowSecond - 90) + "deg)";
}
3.添加定時(shí)器:
js代碼如下:
代碼如下:
//定時(shí)器
function startMove() {
clearInterval(timer);
timer = setInterval(function () {
var now = new Date();
var nowSecond = now.getSeconds();
var nowMinute = now.getMinutes();
var nowHour = now.getHours();
second.style.transform = "rotate(" + (nowSecond * 6 - 90) + "deg)";
minute.style.transform = "rotate(" + (nowMinute * 6 + 1 / 10 * nowSecond - 90) + "deg)";
hour.style.transform = "rotate(" + (nowHour * 30 + 1 / 2 * nowMinute + 1 / 120 * nowSecond - 90) + "deg)";
timeLabel.innerHTML = nowHour + ":" + nowMinute + ":" + nowSecond;
}, 1000);
}
4.使用OOP方式更改:
修改后的js代碼如下:
代碼如下:
function Clock() {
//定義屬性
this.main = this.$("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(pán)
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(diào)用如下:
代碼如下:
window.onload = function () {
new Clock();
}
最終頁(yè)面代碼:
代碼如下:
<!DOCTYPE html>
<html xmlns="<a href="http://www.w3.org/1999/xhtml">http://www.w3.org/1999/xhtml</a>">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

}

height: 4px;
background-color: green;
position: absolute;

transform-origin: 0 50%;
}

}
.hourPointer {
height: 10px;
width: 12px;
left: 150px;
top: 145px;
