禁用聚集点的弹出窗口 [英] Disable popups for clustered points

问题描述

我正在运行一个基于地图的服务，其中包含很多(数千个)标记的地方.我决定在集群支持下使用 OpenLayers .

i'm running a map-based service with a lot (few thousands) of marked places. I decided to use OpenLayers with cluster support.

每个点都有它的弹出窗口，其中包含一些基本信息.问题是，当聚集大量点时，这些点(即50个元素)的弹出窗口确实很大，比OpenLayers div大，并且您可以想象-看起来很糟糕.

Each point has it's popup with some basic informations about it. The thing is that when a big amount of points are clustered, the popup for those i.e. 50 elements is really huge, bigger than the OpenLayers div and as you can imagine - it looks terrible.

是否有可能禁用聚集点的弹出窗口?

Is there any possibility to disable popups for clustered points?

预先感谢

推荐答案

在OpenLayers中示例，每次选择功能或群集时都会调用display函数.我猜你也做了类似的事情:

In OpenLayers example, display function is called every time feature or cluster is selected. .I guess you do something similar:

function display(event) {
  //Show popup here      
}

event.feature具有称为cluster的属性，如果它是特征本身，则包含一个特征；如果是集群特征，则包含一组特征.我建议您检查数组的长度，仅在其中具有一项功能时才显示弹出窗口.

event.feature has property called cluster which either contains one feature if it's the feature itself or an array of features if it's a clustered feature. I suggest that you check length of an array and show popup only when you have one feature in it.

这是我看不到您的代码的最好建议:)

That's the best suggestion I can make without seeing your code :)
