 　　<div>
  　　<span @click="show = 0">第一个</span>
   <span @click="show = 2">第二个</span>
   <span @click="show = 3">第三个</span>
  </div>
  <transition-group name="slide">
  　　<div v-show="show == 0" key="0">第一个文本</div>
   <div v-show="show == 2" key="2">第二个文本</div>
   <div v-show="show == 3" key="3">第三个文本</div>
  </transition-group>
 </div>
</template>
<script>
 export default {
  data () {
  　　return {
   show:0
   }
  }
 }
</script>
<style>
 .slide-enter-active{
 　　　　transition:all .5s linear;
 }
 .slide-leave-active{
  transition:all .1s linear;
 }
 .slide-enter{
  transform: translateX(-100%);
  opacity: 0;
 }
 .slide-leave-to{
  transform: translateX(110%);
