我正在使用mapbox创建地图，而我的标记过滤器出现问题。我希望使用已经激活的过滤器加载地图。我目前有两个按钮;发展和土地。它们都按预期工作，但我希望地图加载＆＃34;开发＆＃34;过滤ALREADY有效。由于地图载荷并且所有标记都可见，导致某些区域（如佐治亚州东南部）看起来非常拥挤。我已经在好几个地方看过并尝试过mapbox客户支持，但他们似乎并不理解我的问题。如果需要更多信息，请告诉我。

答案 0 :(得分：1)
解决方案是在myLayer.setGeoJSON(geoJson).addTo(map);之后直接添加以下内容吗？
myLayer.setFilter(function(f) {
return f.properties['development'] === true;
});
