我正在尝试为我的项目开发具有显示/隐藏标记功能的 map 。但我没有适当的 javascript 知识。所以我现在在谷歌上找了一段时间。并看到很多与此相关的帖子。现在我正在使用 post shows here 中的代码
那篇文章中的 map 很好，但这篇文章中存在一些不足。
它仅显示标记，但再次单击复选框时不会隐藏。
一次仅显示一个类别
代码:

<script type="text/javascript">
var beaches = [
['Bondi Beach', -33.890542, 151.274856, 1,],
['Coogee Beach', -33.923036, 151.259052, 1],
['Cronulla Beach', -34.028249, 151.157507, 2],
['Manly Beach', -33.800101, 151.287478, 2],
['Maroubra Beach', -33.950198, 151.259302, 2]
];
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 10,
center: new google.maps.LatLng(-33.88, 151.28),
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var markers = [];
var i, newMarker;
for (i = 0; i < beaches.length; i++) {
newMarker = new google.maps.Marker({
position: new google.maps.LatLng(beaches[i][1], beaches[i][2]),
map: map,
title: beaches[i][0]
});
newMarker.category = beaches[i][3];
newMarker.setVisible(false);
markers.push(newMarker);
}
function displayMarkers(category) {
var i;
for (i = 0; i < markers.length; i++) {
if (markers[i].category === category) {
markers[i].setVisible(true);
}
else {
markers[i].setVisible(false);
}
}
}

最佳答案
Please check this code it should be working for you.
这里只需要添加jquery版本文件即可。 并简单地检查复选框是否单击 你需要将visible设置为true的时候，否则它会变成false 检查我的代码 试试这个，
