mapbox - Mapbox: How to avoid JavaScript errors for tilesets that aren't available at the current zoom level?

Question

I'm using Mapbox GL JS and loading tileset layers from my Mapbox account. Some of these tileset layers are only available for zoom levels 10 to 15.

The default zoom level of my map is 5, and when I load the map I get a JavaScript console error, saying that the tileset is 404ing:

Is there any way I can avoid this? I don't want to recreate the tileset all the way to zoom level 5, as it will unnecessarily increase its size.

I don't think the console error is causing any problems in Chrome, but I don't know whether it will in other browsers.

最简单的方法是替换默认的错误处理程序，过滤掉“未找到”消息：

map.on('error', e => {
    // Hide those annoying non-error errors
    if (e && e.error !== 'Error: Not Found')
        console.error(e);
});

在这种情况下，您仍然会看到浏览器提供的GET https://... 404 (Not Found)消息，但看不到 JavascriptError: Not Found异常消息。

如果您使用自己的磁贴服务器，您可以将其设置为提供无内容204 HTTP 状态。

以下是它在定制的 node.js tile 服务器中的样子：

app.use(function(req, res, next) {
  if(res.status(404)) {
    res.sendStatus(204)
  }
});
