老师，ratingselect派发的消息在父组件收到了，如下：

events: {

'rating.change'(bool) {

  this.onlyContent === bool;

  console.log('events:'+bool);

  },

'rating.select'(type) {

  this.selectType === type;

  console.log('events:'+type);

  }

}

但v-show绑定的needshow却没重新执行，还是之前默认设置的值，导致评价切换按钮失效，v-show="showRating(rating.rateType,rating.text)"

showRating (type, text) {

 if (this.onlyContent && !text){

 console.log('onlycontent');

 return false;

 }

 if (this.selectType === ALL){

   console.log('selectType'+this.selectType);

   return true;

   }else {

   return type === this.selectType;

   }

},
