选项卡在页面中很常见，今天学习了下，记录下来。代码如下：
1 <!DOCTYPE html> 2 <html lang="en"> 3 <head> 4 <meta charset="UTF-8"> 5 <meta name="viewport" content="width=device-width, initial-scale=1.0"> 6 <meta http-equiv="X-UA-Compatible" content="ie=edge"> 7 <title>选项卡</title> 8 <style> 9 #container div { 10 width: 300px; 11 height: 200px; 12 border: 3px solid red; 13 display: none; 14 margin-top: 10px; 15 text-align: center; 16 line-height: 200px; 17 font-size: 30px; 18 } 19 20 #container div.active { 21 display: block; 22 } 23 24 button { 25 outline: none; 26 border: 2px solid gray; 27 border-radius: 5px; 28 } 29 30 button.active { 31 background-color: orange; 32 } 33 </style> 34 </head> 35 <body> 36 <div id="wrap"> 37 <button class="active">选项一</button> 38 <button>选项二</button> 39 <button>选项三</button> 40 <button>选项四</button> 41 <div id="container"> 42 <div class="active">内容一</div> 43 <div>内容二</div> 44 <div>内容三</div> 45 <div>内容四</div> 46 </div> 47 </div> 48 <script> 49 var oWrap = document.getElementById(‘wrap‘) 50 var oBtn = oWrap.getElementsByTagName(‘button‘) 51 var oCon = document.getElementById(‘container‘) 52 var oDiv = oCon.getElementsByTagName(‘div‘) 53 for (var i = 0; i < oBtn.length; i++) { 54 oBtn[i].index = i 55 oBtn[i].onclick = function () { 56 for (var j = 0; j < oBtn.length; j++) { 57 oBtn[j].style.backgroundColor = ‘white‘ 58 oDiv[j].style.display = ‘none‘ 59 } 60 this.style.backgroundColor = ‘orange‘ 61 oDiv[this.index].style.display = ‘block‘ 62 } 63 } 64 </script> 65 </body> 66 </html>
效果如下：
这里只是简单记录，代码还不够精简，见谅。
