地理对象从 geojson 文件加载到地图上，我需要两个选项来使用多边形和标签打开地图，并且仅使用多边形，无法更改 geojson 文件，我需要制作没有标签的第二个版本的脚本。

 ymaps.ready(init);
 function init() {
var myMap = new ymaps.Map('map', {
        center: [30.448166334957177, 59.9220776628873],
        zoom: 15,
        controls: ['searchControl']
    }),

searchControl = myMap.controls.get('searchControl');
searchControl.options.set({noPlacemark: true, placeholderContent: 'Введите адрес'});

function onZonesLoad(json) {
    // Добавляем зоны на карту.
    var deliveryZones = ymaps.geoQuery(json).addToMap(myMap);
    // Задаём цвет и контент балунов полигонов.
    deliveryZones.each(function (obj) {
        obj.options.set({
            fillColor: obj.properties.get('fill'),
            fillOpacity: obj.properties.get('fill-opacity'),
            strokeColor: obj.properties.get('stroke'),
            strokeWidth: obj.properties.get('stroke-width'),
            strokeOpacity: obj.properties.get('stroke-opacity')
        });
         obj.properties.set('balloonContent', obj.properties.get('description'));
        });
           }

$.ajax({
    url: 'lib/cart.geojson',
    dataType: 'json',
    success: onZonesLoad
   });
  }

需要通过geoObjects.geojson文件更改标签的颜色并自动更新html页面。

  ymaps.ready(function () {

var map = new ymaps.Map('map', {
        center: [30.448166334957177, 59.9220776628873],
        zoom: 15,
        controls: ['zoomControl']
    }),
    objectManager = new ymaps.ObjectManager();
map.controls.get('zoomControl').options.set({size: 'small'});
// Загружаем GeoJSON файл, экспортированный из Конструктора карт.
$.getJSON('geoObjects.geojson')
    .done(function (geoJson) {
        geoJson.features.forEach(function (obj) {
            // Задаём контент балуна.
            obj.properties.balloonContent = obj.properties.description;
            // Задаём пресет для меток с полем iconCaption.
            if (obj.properties.iconCaption) {
                obj.options = {
                    preset: "islands#darkgreenCircleIcon"
                }
            }
        });
        // Добавляем описание объектов в формате JSON в менеджер объектов.
        objectManager.add(geoJson);
        // Добавляем объекты на карту.
        map.geoObjects.add(objectManager);
    });
