栅格化布局做的简单抽奖
作者:互联网
用栅格化布局做的一个抽奖机,里面的内容可自行修改。
下面就开始分享代码:
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title></title> <style type="text/css"> /* 让article变成容器 */ article { width: 800px; height: 910px; border: 1px saddlebrown solid; display: grid; grid-template-rows: repeat(6, 1fr); grid-template-columns: repeat(6, 1fr); } /* div样式 */ div { border: 1px saddlebrown solid; text-align: center; line-height: 150px; } /* 下面是给盒子调样式 */ div:nth-child(7) { grid-row-start: 2; grid-column-start: 6; } div:nth-child(8) { grid-row-start: 3; grid-column-start: 6; } div:nth-child(9) { grid-row-start: 4; grid-column-start: 6; } div:nth-child(10) { grid-row-start: 5; grid-column-start: 6; } div:nth-child(11) { grid-row-start: 6; grid-column-start: 6; } div:nth-child(12) { grid-row-start: 6; grid-column-start: 5; } div:nth-child(13) { grid-row-start: 6; grid-column-start: 4; } div:nth-child(14) { grid-row-start: 6; grid-column-start: 3; } div:nth-child(15) { grid-row-start: 6; grid-column-start: 2; } div:nth-child(16) { grid-row-start: 6; grid-column-start: 1; } div:nth-child(17) { grid-row-start: 5; grid-column-start: 1; } div:nth-child(18) { grid-row-start: 4; grid-column-start: 1; } div:nth-child(19) { grid-row-start: 3; grid-column-start: 1; } button:nth-child(21) { grid-row-start: 3; grid-column-start: 3; } button:nth-child(22) { grid-row-start: 3; grid-column-start: 4; } </style> </head> <body> <article> <div>1</div> <div>2</div> <div>3</div> <div>4</div> <div>5</div> <div>6</div> <div>7</div> <div>8</div> <div>9</div> <div>10</div> <div>11</div> <div>12</div> <div>13</div> <div>14</div> <div>15</div> <div>16</div> <div>17</div> <div>18</div> <div>19</div> <div>20</div> <button type="button">开始</button> <button type="button">停止</button> </article> <script type="text/javascript"> // 获取所有的盒子 var div = document.querySelectorAll('div') // 获取两个按钮 var btn = document.querySelectorAll('button') // 定义一个空值为定时器做准备 var timer = null // 定义一个计数器 var i = 0 // 为开始设置点击事件 btn[0].onclick = function() { // 定义定时器 timer = setInterval(function() { // 让计数器依次递增 i++ // 这里就是排他思想 for (var j =0;j< div.length;j++) { // 让其他div的背景颜色变成空 div[j].style.backgroundColor = '' } // 判断计数器如果大于20的话 if (i >= 20) { // 就让背景颜色回归原位 i = -1 } else { // 否则背景颜色就变化 div[i].style.backgroundColor = '#FFD700' } // 每隔10毫秒执行一次 }, 10) } // 给停止设置点击事件 btn[1].onclick = function() { // 点击之后停止定时器 clearInterval(timer) } </script> </body> </html>
