使用信息块显示/隐藏类别中的标记

Question

我有属于多个类别的标记，我希望能够使用复选框隐藏/显示基于类别的标记。我已经让复选框在没有连接信息的情况下工作，但是现在我附加了infowindow，复选框不再起作用了。我认为show和hide函数无法以某种方式访问​​arrMarkers.category，因为当我注释掉marker.setVisibile(false)时，所有标记都是可见的。但是有了那条线，不知何故第一个标记仍然可见，而其他所有标记都不是......

这是我的代码，如果有人可以向我解释为什么它不起作用，那就太棒了：

var markerData = [
                ['blueforce1', 52.308584, 4.767637, 1, 'yellow', 'yes'],
                ['blueforce2', 52.308656, 4.76517, 1, 'yellow', 'yes'],
                ['blueforce3', 52.308656, 4.72517, 1, 'yellow', 'yes'],
                ['blueforce4', 52.309686, 4.762734, 2, 'red', 'yes'],
                ['blueforce5', 52.309463, 4.771693, 2, 'red', 'yes'],
                ['blueforce6', 52.309963, 4.771693, 2, 'red', 'yes'],
                ['camera7', 52.308656, 4.76517, 3, 'camera', 'no'],
                ['blueforce8', 52.318656, 4.73517, 3, 'camera', 'no'],
