本文实例为大家分享了JavaScript实现简易tab栏切换效果的具体代码,供大家参考,具体内容如下 1. tab栏-案例1tab栏分析 li里面的分析 js实现隐藏与显示 排他思想: 1)、所有元素全部清除样式(干掉其他人) 我的思路: 代码实现: <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <style> * { margin: 0; padding: 0; } li { list-style: none; } a { text-decoration: none; color: #666; } .vertical-tab { width: 980px; margin: 100px auto; } .vertical-tab .nav { width: 200px; list-style: none; } .vertical-tab .nav-tabs1 { float: left; border-right: 3px solid #e7e7e7; } .vertical-tab .nav-tabs2 { float: right; border-left: 3px solid #e7e7e7; } .vertical-tab li a { display: block; padding: 10px 20px; text-align: center; text-transform: uppercase; letter-spacing: 1px; font-size: 18px; font-weight: 700; } .vertical-tab .active { color: #198df8; } .vertical-tab .tabs { width: 500px; float: left; } .vertical-tab .tab-content { padding: 10px 20px; text-transform: uppercase; letter-spacing: 1px; } .vertical-tab .tab-content h3 { color: #333; margin: 0 0 10px 0; } .vertical-tab .tab-content p { font-size: 12px; } .vertical-tab .hidden { display: none; } </style> </head> <body> <div class="vertical-tab"> <ul class="nav nav-tabs1"> <li><a href="javascript:;" class="active" index="1">section 1</a></li> <li><a href="javascript:;" index='2'>section 2</a></li> <li><a href="javascript:;" index="3">section 3</a></li> </ul> <div class="tab-content tabs"> <div class="tab-content1"> <h3>section 1</h3> <p>content 1</p> </div> <div class="tab-content1 hidden"> <h3>section 2</h3> <p>content 2</p> </div> <div class="tab-content1 hidden"> <h3>section 3</h3> <p>content 3</p> </div> <div class="tab-content1 hidden"> <h3>section 4</h3> <p>content 4</p> </div> <div class="tab-content1 hidden"> <h3>section 5</h3> <p>content 5</p> </div> <div class="tab-content1 hidden"> <h3>section 6</h3> <p>content 6</p> </div> </div> <ul class="nav nav-tabs2"> <li><a href="javascript:;" index="4">section 4</a></li> <li><a href="javascript:;" index="5">section 5</a></li> <li><a href="javascript:;" index="6">section 6</a></li> </ul> </div> <script> var as = document.querySelectorAll("a") var item = document.querySelectorAll(".tab-content1") console.log(as) // console.log(lis) for (var i = 0; i < as.length; i++) { as[i].addEventListener('click', function() { // 干掉其他人 for (var j = 0; j < as.length; j++) { as[j].className = '' } // 留下自己 this.className = "active" // 显示内容 var index = this.getAttribute('index') console.log(index) // 干掉其他人 for (var i = 0; i < item.length; i++) { item[i].style.display = "none" } // 留下自己 item[index - 1].style.display = "block" }) } </script> </body> </html> vue实现 vue实现起来相对简单,只需要灵活运用v-if和v-for 具体代码: <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>Document</title> <style> * { margin: 0; padding: 0; } .vertical-tab { width: 920px; margin: 100px auto; } .vertical-tab .nav { list-style: none; width: 200px; } .vertical-tab .nav-tabs1 { border-right: 3px solid #e7e7e7; } .vertical-tab .nav-tabs2 { border-left: 3px solid #e7e7e7; } .vertical-tab .nav a { display: block; font-size: 18px; font-weight: 700; text-align: center; letter-spacing: 1px; text-transform: uppercase; padding: 10px 20px; margin: 0 0 1px 0; text-decoration: none; } .vertical-tab .tab-content { color: #555; background-color: #fff; font-size: 15px; letter-spacing: 1px; line-height: 23px; padding: 10px 15px 10px 25px; display: table-cell; position: relative; } .vertical-tab .nav-tabs1 { float: left; } .vertical-tab .tabs { width: 500px; box-sizing: border-box; float: left; } .vertical-tab .tab-content h3 { font-weight: 600; text-transform: uppercase; margin: 0 0 5px 0; } .vertical-tab .nav-tabs2 { float: right; } .tab-content { position: relative; } .tab-content .tab-pane { position: absolute; top: 10px; left: 20px; } .nav li.active a { color: #198df8; background: #fff; border: none; } .fade { opacity: 0; transition: all .3s linear; } .fade.active { opacity: 1; } </style> </head> <body> <div class="vertical-tab" id="app"> <!-- Nav tabs --> <ul class="nav nav-tabs1"> <li v-on:click='change(index,0)' :class='currentIndex==index?"active":""' v-if="index < list.length/2" v-for="(item, index) in list"><a href="#" rel="external nofollow" rel="external nofollow" > {{item.title}} </a></li> </ul> <!-- Tab panes --> <div class="tab-content tabs"> <div class="tab-pane fade" :class='currentIndex==index?"active":""' :key='item.id' v-for='(item, index) in list'> <h3>{{item.title}}</h3> <p>{{item.content}}</p> </div> </div> <!-- Nav tabs --> <ul class="nav nav-tabs2"> <li v-on:click='change(index,1)' :class='currentIndex==index?"active":""' v-if="index >= list.length/2" v-for="(item, index) in list"><a href="#" rel="external nofollow" rel="external nofollow" > {{item.title}} </a></li> </ul> </div> <script type="text/javascript" src="js/vue.js"></script> <script> new Vue({ el: "#app", data: { currentIndex: 0, // 选项卡当前的索引 list: [{ id: 1, title: 'Section 1', content: 'content1' }, { id: 2, title: 'Section 2', content: 'content2' }, { id: 3, title: 'Section 3', content: 'content3' }, { id: 4, title: 'Section 4', content: 'content4' }, { id: 5, title: 'Section 5', content: 'content5' }, { id: 6, title: 'Section 6', content: 'content6' }] }, methods: { change(index, flag) { if (flag) { console.log(index) this.currentIndex = index; } else { this.currentIndex = index; } } } }) </script> </body> 如果大家还想深入学习,可以点击两个精彩的专题:javascript选项卡操作方法汇总 jquery选项卡操作方法汇总 以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持极客世界。 |
