Question

我有多家酒店：

      var hotels = [
        {
          name: 'Ritz Carlton',
          rating: 5,
          description: 'The most luxurious place in the world',
          mealType: 'AI',
          features: ['wifi', 'conference', 'beach'],
          region: 'Kemer'
        },
        etc.

我正在创建一个过滤器函数，该函数将返回经过过滤的，符合某些条件的酒店数组。

为什么此代码起作用？

if(formRating.value == 5) {return hotel.rating == 5;}

并且此功能不：

    function chooseFeaures(hotel)  {
      Array.from(chosenFeature).forEach(feature => {
      if(feature.checked) {
         if(feature.value == 'wifi') {return hotel.features.includes('wifi');}
         if(feature.value == 'beach') {return hotel.features.includes('beach');}
         if(feature.value == 'gym') {return hotel.features.includes('gym');}
         if(feature.value == 'conference') {return hotel.features.includes('conference');}
         else {return hotel.features == 'wifi';}
      }
        });

    }

当我做if（feature.checked）{console.log（feature.value）};它有效

if（feature.value =='beach'）{console.log（'beach'）;}也可以

当我这样做时：

  let filtered =  hotels.filter( hotel => {
      return hotel.features.includes('gym');
    });

它也可以工作。

输入看起来像这样：

 <label>
     <input type="checkbox" class="filled-in" value="wifi" name="feature"/>
     <span>Wi-Fi</span>
 </label>

变量：让selectedFeature = document.getElementsByName（'feature'）;

并且函数正在内部运行：

    let filteredCards = hotels.filter(function(hotel, index, hotels) {
      return chooseFeaures(hotel);
    });

很抱歉这么长的问题，但是我想使其尽可能详细

即使'if'条件为真，Return语句也不起作用
