Vue.component('tab-home', { template: `<div>Home component</div>`
})
Vue.component('tab-posts', { template: `<div>Posts component</div>`
})
Vue.component('tab-archive', { template: `<div>Archive component</div>`
})

 Vue.use( TabHome); // 自定義全局組件的時候需要Vue.use();
  Vue.component('tab-home', TabHome)); //初始化組件
two ----局部組件引入 ，寫在需要的引入的組件，如helloworld
import TabAa from './tab-aa.vue'
import TabBb from './tab-bb.vue'
import TabCc from './tab-cc.vue'
export default {
name: 'HelloWorld',
components:{TabAa,TabBb,TabCc},
three----動態(tài)組件（tab切換 使用:is="currentTabComponent"）
<template>
<>
<button
v-for="tab in tabs"
v-bind:key="tab"
v-bind:class="['tab-button', { active: currentTab === tab }]"
v-on:click="currentTab = tab"
>{{ tab }}</button>
<component
v-bind:is="currentTabComponent"
class="tab"
></component>
</div>
</template>
export default {
name: 'HelloWorld',
components:{TabAa,TabBb,TabCc},
data () {
return {
currentTab: 'Home',
tabs: ['Home', 'Posts', 'Archive','Aa','Bb','Cc'],
loginType:'username',
msg: 'Welcome to Your Vue.js App'
}
},
computed: {
currentTabComponent: function () {
return 'tab-'+this.currentTab.toLowerCase()
}
},
樣式：
.tab-button {
padding: 6px 10px;
border-top-left-radius: 3px;
border-top-right-radius: 3px;
border: 1px solid #ccc;
cursor: pointer;
background: #f0f0f0;
margin-bottom: -1px;
margin-right: -1px;
}
.tab-button:hover {
background: #e0e0e0;
}
.tab-button.active {
background: #e0e0e0;
}
.tab {
border: 1px solid #ccc;
padding: 10px;
}
