Question

我正在使用mapbox开发地图并遇到了障碍。我正在尝试使用自定义标记并在地图中使用按钮来过滤我的标记，因此根据哪个按钮处于活动状态，只显示某些标记。问题是我似乎能够让一个或另一个工作，而不是两个。我可以有一个带有自定义标记的地图，但没有过滤器或带有内置标记和工作过滤器的地图。我几乎不知道HTML以外的任何代码，并且已经按照mapboxes示例开发了地图。如果有人可以看看这个并让我知道我做错了什么以及如何解决它我会非常感激。

以下是我遵循的两个例子： https://www.mapbox.com/mapbox.js/example/v1.0.0/markers-with-multiple-filters/ https://www.mapbox.com/mapbox.js/example/v1.0.0/custom-marker/

这是我的代码，带有工作图标，没有工作过滤器（我删除了大约10个标记，因为它是相同的代码）：

这是我的代码没有自定义标记，但过滤器工作。

我觉得我错过了一些小的东西（可能只是语法），但是我缺乏这种语言的经验和知识使我无法找到它。非常感谢任何帮助。

Answer 1

在第204行无法使用的代码列表中，将markers.setFilter(function(f) {更改为myLayer.setFilter(function(f) {。
