Vue之tab简单切换实现

简单实现过程：

通过v-for实现tab页签，通过@click实现页签切换，通过:class实现绑定当前页，tab切换主要依靠组件component实现，每个页签切换时，不想让改变页签内容，可以用keep-alive实现。具体代码如下：

<template>
  <div id="app">
    <div class="radio-wrap">
      <div class="radio-group" v-model="tabView">
        <span
           v-for="(tab ,index) in tabs"
           :class="{cur:iscur==index}"
           @click="iscur=index,tabChange('select' + (index + 1))">
             {{tab.name}}
        </span>
      </div>
      <div style="margin:10px 0;"></div>
      <keep-alive>
        <component v-bind:is="tabView"></component>
      </keep-alive>
    </div>
  </div>
</template>

<script>
  import select1 from './components/select01.vue';
  import select2 from './components/select02.vue';
  import select3 from './components/select03.vue';
  export default {
    name: 'app',
      data () {
        return {
          tabView: 'select1',
          iscur: 0,
          tabs: [{name: "选项一"}, {name: "选项二"} ,{name: "选项三"}]
        }
  },
  components: {
    select1,
    select2,
    select3
  },
  methods: {
    tabChange:function(tab){
      this.tabView = tab;
    }
  }
}
</script>
