Vue选项卡效果
没馅儿小笼包 人气:0效果图
1.头部选项卡
点击切换下标ID 传递一个参数回去，active绑定选中样式
<div id="app">
<ul>
<li v-for='(item,index) in list' @click='check(index)' :class="{ active: index === TabId }">
<h1> {{item.title}}</h1>
</li>
</ul>
</div>2.完整HTML
默认使用V-show来切换，获取盒子下标，没有dom操作
当然，Vue官方文档也不推荐V-if和V-for同时使用
<div id="app">
<ul>
<li v-for='(item,index) in list' @click='check(index)' :class="{ active: index === TabId }">
<h1> {{item.title}}</h1>
</li>
</ul>
<div class="mycontent" v-for='(item,index) in list' v-show="index === TabId">
<h1>{{item.content}}</h1>
</div>
</div>3.Vue
下标默认为0
<script>
//清除默认提示样式
Vue.config.devtools = false
Vue.config.productionTip = false
let vm = new Vue({
el: '#app',
data() {
return {
//下标ID 默认从零开始
TabId: 0,
list: [
{
title: 'Itachi',
content: 'VUE'
},
{
title: 'Sasuke',
content: 'HTML'
},
{
title: 'Obito',
content: 'CSS'
},
{
title: 'Madara',
content: 'JavaScript'
},
]
}
},
methods: {
//将点击事件获取的下标ID传递给要切换的盒子
check(index) {
this.TabId = index;
},
}
});
