按类别使用GeoRSS过滤Google地图标记 [英] Filtering Google Maps Markers By Category Using GeoRSS

问题描述

我已经有一个地图设置了从geoRSS文件显示标记。这些标记按类别分组。我想要做的是为类别设置文本链接，点击后隐藏除关联组中的标记之外的所有标记。不知道从哪里开始。

解决方案

我之前没有使用geoRSS，但请参阅本教程，了解如何按类别过滤标记。 V3的版本适用于此处 - 希望与您期待的目标接近！

I've got a map set up displaying markers from a geoRSS file. These markers are grouped by category. What I'd like to do is set up text links for the categories that, when clicked, hide all markers except for those in the associated group. Not sure where to start with this.

解决方案

I've not worked with geoRSS before, but see this tutorial for how to go about filtering markers by category. There's a version for V3 here - hope that is close to what you're looking to do!
