前端 javascript 讀心術 html5 DOM
知識點:讀心術原理算法獨家揭秘,html5最新選擇器,原生js動態dom生成,控制流程講解,函數封裝與模塊化思維,定時器混合運用與幀動畫,JavaScript知識體系分享。
html代碼:
<div class="cont"> <div class="wrap"></div> <div class="box"> <div class="explain"> <strong>遊戲規則:</strong><br>任意選擇一個兩位數(或者說,從10~99之間任意選擇一個數),把這個數的十位與個位相加,再把任意選擇的數減去這個和。並把這個圖形牢記心中,然後點擊水晶球。<br>你會發現,水晶球所顯示出來的圖形就是你剛剛心裏記下的那個圖形。<br>例如:你選的數是23,然後2+3=5,然後23-5=18,在圖表中找出與最後得出的數所相應的圖形 </div> <div class="showbox"><img src="" ></div> <div class="btnRe">刷 新</div> </div> </div>
css代碼:
<style type=‘text/css‘> * { margin: 0; padding: 0; } body { background-color: rgba(52, 52, 53, 0.82); } .cont { width: 880px; height: auto; margin: 20px auto; background-color: rgba(255, 205, 156, 0.64); overflow: hidden; border-radius: 30px } .wrap { width: 480px; margin: 20px; overflow: hidden; float: left; box-shadow: 0 0 4px rgba(59, 44, 49, 0.8); padding: 10px 0 10px 10px; border-radius: 20px; } .wrap div { width: 30px; height: 30px; float: left; margin: 0 10px 30px 0; text-align: center; box-shadow: 0 0 1px #aa64c8; border-radius: 100% } .wrap div img { display: block; overflow: hidden; border-radius: 100% } .wrap div span { font-size: 20px; font-family: Andalus; color: #000000; text-shadow: 0 1px 0px #000000; line-height: 10px } .box { width: 310px; margin: 0 auto; float: left; } .box .explain { padding: 10px; margin: 0 auto; width: 300px; font-size: 16px; line-height: 25px; color: #000000; font-family: ‘Microsoft JhengHei‘; font-weight: bold; } .box .btnRe { width: 100px; margin: 20px auto; text-align: center; line-height: 40px; background-color: rgba(255, 205, 156, 0.64); font-size: 16px; color: #000000; cursor: pointer; padding: 3px; border-radius: 10px; font-weight: 300; } .box .btnRe:hover { border: 3px solid rgba(255, 205, 156, 0.64); background-color: #6c85c8; color: rgba(255, 205, 156, 0.64); padding: 0; } .box .showbox { width: 120px; height: 120px; background-color: rgba(255, 230, 207, 0.64); margin: 10px auto; border-radius: 50%; overflow: hidden; box-shadow: 0 0 10px #aa64c8; } .box .showbox img { opacity: 0.3; } .cont .box .on { animation: active 2s; -webkit-animation: active 2s; } @keyframes acitve { 0% { box-shadow: 0 0 50px #c789c8; } 50% { box-shadow: 0 0 30px #aa64c8; } 100% { box-shadow: 0 0 10px #aa64c8; } } @-webkit-keyframes active { 0% { box-shadow: 0 0 50px #c789c8; } 50% { box-shadow: 0 0 30px #aa64c8; } 100% { box-shadow: 0 0 10px #aa64c8; } } </style>
javascript代碼:
<script type="text/javascript" src="js/jquery-2.2.0.min.js"></script> <script> /*公式: ab 10a+b-a-b=9a OR 10a-a=9a */ (function () { var $wrap = $(‘.wrap‘), $show = $(‘.showbox‘); var str = ‘‘; var timer = null; var timerout = null; for (var i = 1; i <= 96; i++) { str += ‘<div><img src="" width="30" height="30" autocomplete="off"><span>‘ + i + ‘</span></div>‘ } $wrap.append(str); init(); $(‘.btnRe‘).click(function () { reset(); $show.removeClass(‘on‘).find(‘img‘).attr(‘src‘, ‘‘).stop().animate({opacity: 0.3,}, 1000); timer = setInterval(init, 10); timerout = setTimeout(function () { clearInterval(timer) }, 1000); }) $(‘.showbox‘).click(function () { reset(); timer = setInterval(start, 10); timerout = setTimeout(end, 1000); }) function init() { var ran = Math.floor(Math.random() * 99) + 1; $(‘.wrap‘).find(‘div‘).each(function (i) { var ran1 = Math.floor(Math.random() * 99) + 1; if (i % 9 == 0) { $(‘.wrap‘).find(‘div‘).eq(i - 1).find(‘img‘).attr(‘src‘, ‘img/‘ + (ran) + ‘.png‘); } else { $(‘.wrap‘).find(‘div‘).eq(i - 1).find(‘img‘).attr(‘src‘, ‘img/‘ + (ran1) + ‘.png‘); }; }); }; function reset() { clearTimeout(timerout); clearInterval(timer); }; function start() { var x = Math.floor(Math.random() * 99) + 1; $show.addClass(‘on‘).find(‘img‘).attr(‘src‘, ‘img/‘ + x + ‘.png‘).css({opacity: 0.3}) }; function end() { clearInterval(timer) clearTimeout(timerout) var img = $wrap.find(‘div‘).eq(8).find(‘img‘).attr(‘src‘); $show.addClass(‘on‘).find(‘img‘).attr(‘src‘, img).stop().animate({opacity: 1,}, 3000); }; })() </script>
