css3-hand-in-hand 変換小さな時計_html/css_WEB-ITnose

私は css3ing を学習していて、transformr を学習しています。これを使って小さな時計を作ることを突然思いつきました。 始めましょう:

1. 事前作業を準備し、時計の文字盤、時、分、秒を作成します。

<div class="main"> <div id="timeLabel"></div> <div id="hour"></div> <div id="minute"></div> <div id="second"></div> </div>

css コードは次のとおりです:

 1  <style>  2  * {  3  margin: 0;  4  padding: 0;  5 }  6  .main {  7  position: relative;  8  margin: 100px auto;  9  width: 300px; 10  height: 300px; 11  border-radius: 300px; 12  border: 1px solid #000; 13  box-shadow:2px 5px; 14 } 15  #timeLabel { 16  position: absolute; 17  background-color:pink; 18  width:100px; 19  height:30px; 20  left:100px; 21  top:180px; 22 } 23 24  #hour { 25  width: 100px; 26  height: 10px; 27  background-color: red; 28  position:absolute; 29  left:150px; 30  top:145px; 31 } 32  #minute { 33  width:120px; 34  height:8px; 35  background-color:blue; 36  position:absolute; 37  left:150px; 38  top:146px; 39 } 40  #second { 41  width: 140px; 42  height: 4px; 43  background-color: green; 44  position: absolute; 45  left: 150px; 46  top: 148px; 47 } 48  </style>

2. デフォルトを初期化します。時間とダイヤルスケールの効果は次のとおりです:

変更されたCSコード:

 <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>

初期化jsコード:

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;            //初始化表盘            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);            }            //初始化时分秒针            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. タイマーを追加します。

jsコードは次のとおりです以下:

 //定时器        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. OOPメソッドを使用して変更します:

変更されたjsコードは次のとおりです:

function Clock() {            //定义属性            this.main = this.$("biaopan");            this.timeLabel = this.$("timeLabel");            this.hour = this.$("hour");            this.minute = this.$("minute");            this.second = this.$("second");            this.nowHour = null;            this.nowMinute = null;            this.nowSecond = null;            this.timer = null;            var _this = this;            //初始化函数            var init = function () {                _this.getNowTime();                _this.initClock();                _this.InterVal();            }            init();        }        Clock.prototype.$ = 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;            //初始化表盘            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);        }

最後の呼び出しは次のとおりです:
