本文实例为大家分享了vue实现选项卡案例的具体代码,供大家参考,具体内容如下
实现静态UI效果
基于数据重构UI效果
声明式编程
我们先把每组数据作为对象存储在数组中
1 2 3 4 5 6 7 8 9 10 11 12 13 |
list: [{ id: 1, title: 'apple', path: 'images/苹果.jpg' }, { id: 2, title: 'orange', path: 'images/橘子.jpg' }, { id: 3, title: 'lemon', path: 'images/柠檬.jpg' }] |
然后通过v-for对这个数组进行遍历,取到对应的title值
1 |
<li :key='item.id' v-for='(item,index) in list'>{{item.title}}</li> |
对图片也进行遍历
1 2 3 |
<div :key='item.id' v-for='(item,index) in list'> <img src="item.path"> </div> |
具体代码如下
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 |
