Vue动态组件绑定

有些时候，我们需要好几个组件进行来回切换，那么我们就需要借助Vue的<compoenent>元素和:is属性进行操作，下面开始演示。

父组件

<template>
  <div class="demo">
    <button
    v-for="tab of tabs"
    :key="tab"
    :class="['tab-button', { active: currentTab === tab}]"
    @click="currentTab=tab"
    >{{ tab }}</button>
    <component :is="currentTab"></component>
  </div>
</template>
<script>
import Home from './components/Home.vue'
import Posts from './components/Posts.vue'
import Archive from './components/Archive.vue'
export default {
  components: {
    Home,
    Posts,
    Archive
  },
  data() {
    return {
      currentTab: 'Home',
      tabs: ['Home', 'Posts', 'Archive']
    }
  }
}
</script>
<style>
.demo {
  font-family: sans-serif;
  border: 1px solid #eee;
  border-radius: 2px;
  padding: 20px 30px;
  margin-top: 1em;
  margin-bottom: 40px;
  user-select: none;
  overflow-x: auto;
}

.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;

</style>
