  <div>
    <label class="form-label">{{ getLabel | capitalize }}</label>
    <input
      v-tooltip="getTooltipContent"
      :bind="$attrs"
      :type="type"
      :value="value"

      :class="getClass"
      class="form-input"
      data-vv-validate-on="none"
      v-on="{
        ...$listeners,
        input: event => $emit('input', event.target.value)
      }">
  </div>
</template>

** 我的.babelrc **中已经有第二阶段和transform-object-rest-spread了。
