单文件组件之data属性

<script>
import $ from 'jquery'
import AsideBJ from '../AsideBJ/AsideBJ'
export default {
  name: 'head',
  data: function () {
    return {
      msg: 'Welcome to baijia'
    }
  },
  components: {
    AsideBJ
  },
  methods: {
    showMenu () {
      $('.aside').addClass('hide')
    }
  }
}
</script>

data通常缩写成以下：

data () {
    return {
      msg: 'Welcome to baijia'
    }        
}
