jquery css顏色正在改變每個選擇器，但字體大小不是？

-1

我與谷歌地圖的工作，我有標記的數組，它看起來像這樣：jquery css顏色正在改變每個選擇器，但字體大小不是？

var locations = [ 
     [{ 
      id: 1, 
      lat: 51.5239935252832, 
      lng: 5.137663903579778, 
      content: 'Kids Jungalow (5p)' 
     }], 
     [{ 
      id: 2, 
      lat: 51.523853342911906, 
      lng: 5.1377765563584035, 
      content: 'Kids Jungalow (5p)' 
     }], 
     [{ 
      id: 3, 
      lat: 51.5237298485607, 
      lng: 5.137969675407476, 
      content: 'Kids Jungalow (5p)' 
     }], 
     [{ 
      id: 4, 
      lat: 51.52355628836575, 
      lng: 5.138066234932012, 
      content: 'Kids Jungalow (5p)' 
     }], 
     [{ 
      id: 5, 
      lat: 51.52340275379578, 
      lng: 5.138211074218816, 
      content: 'Kids Jungalow (5p)' 
     }], 
     [{ 
      id: 6, 
      lat: 51.523199152806626, 
      lng: 5.138382735595769, 
      content: 'Kids Jungalow (5p)' 
     }], 
     [{ 
      id: 7, 
      lat: 51.5229955509073, 
      lng: 5.138511481628484, 
      content: 'Kids Jungalow (5p)' 
     }], 
     [{ 
      id: 8, 
      lat: 51.52280529912936, 
      lng: 5.138543668136663, 
      content: 'Kids Jungalow (5p)' 
     }], 
     [{ 
      id: 9, 
      lat: 51.523596340777075, 
      lng: 5.138463201866216, 
      content: 'Kids Jungalow (5p)' 
     }], 
     [{ 
      id: 700, 
      lat: 51.523372714362736, 
      lng: 5.1386992362595265, 
      content: 'Kids Jungalow (5p)' 
     }], 
     [{ 
      id: 101, 
      lat: 51.52329594683302, 
      lng: 5.138838711128301, 
      content: 'Kids Jungalow Giraffe' 
     }]

比我環槽標記列陣和一個HTML標記組這樣的每一個位置：

for (i = 0; i < locations.length; i++) { 
    var myLatLng = new google.maps.LatLng({ 
     lat: locations[i][0].lat, 
     lng: locations[i][0].lng 
    }); 
    var number = locations[i][0].id; 
    var marker_html = '<div id="' + number + '"><div class="rich-marker"><span class="number-id">' + number + '</span></div></div>'; 

    var marker = new RichMarker({ 
     position: myLatLng, 
     map: map, 
     flat: true, 
     anchor: RichMarkerPosition.MIDDLE, 
     content: marker_html 
    }); 
}

比我想改變類number-id的CSS樣式縮放級別18這樣的：

map.addListener('zoom_changed', function() { 
     // Limit the zoom level 
     if (map.getZoom() < minZoomLevel) map.setZoom(minZoomLevel); 

     // for loop door locaties 
     for (i = 0; i < locations.length; i++) { 
      setMarkerSize(i); 
     } 
    }); 

    function setMarkerSize(i) { 
     var infobox = locations[i][0].infobox; 
     var id = locations[i][0].id; 

     if (map.getZoom() === 18) { 
      $('.rich-marker').css({ 'display' : 'block', 'width' : '20px', 'height' : '20px' }); 
      $('.number-id').css({ 'display' : 'block', 'font-size' : '12px'}); 

      if (id >= 100) { 
       console.log(id); 
       console.log($('[data-id="' + id + '"]')); 

       $('#' + id).find('.number-id').css('font-size', '10px'); 
       $('#' + id).find('.number-id').css('color', 'red'); 
      } 

      infobox.setOptions({ pixelOffset: new google.maps.Size(-93, -22) }); 
     } 

    }

的顏色是改變所有100以上，但字體大小隻改變爲數組中的最後一個對象爲什麼？

'如果（ID> = 100）{'這裏其中是的'id'從未來值？ – dreamweiver

@dreamweiver抱歉忘了提及一個 – Sreinieren

因爲id不是在循環中構造的，所以它的值在if內部是常量，所以選擇器$（'＃'+ id）.find（'。number-id'）'會只有唯一的值，因爲使用了id選擇器，這意味着css將無法應用於具有id> = 100的所有元素。 – dreamweiver

每次在循環處理標記時要設置所有font-size屬性12px的：

$('.number-id').css({ 
    'display': 'block', 
    'font-size': '12px' 
    });

然後，設置當前標記爲「10px的」的font-size。這隻剩下最後一個你設置爲「10px」。
