如何通过点击HTML元素(在这种情况下为复选框)来显示或隐藏不同组的标记(比如说条形图/电影院/停放处)?
我的标记从循环生成一个数组,如下所示:
markers[i] = new google.maps.Marker({
numero : i,
position: latLng,
map: map,
info: data.Description,
group: data.category,
});
我想我应该使用:
点击我的HTML元素,使用Js函数。
此Js函数应包含此Gmaps方法
调用setVisible
,像这样:
google.maps.event.addListener(marker, 'click', function() {
marker.setVisible(false); // maps API hide call
});
和事件触发器:
google.maps.event.trigger(markers[i], 'click');
但是现在我怎么能把这些东西混在一起:)?

关闭。假设markers
包含给定组中所有标记的数组,您可以为复选框创建一个onchange
处理程序,该处理程序将隐藏组中的所有标记,如此。在您的HTML中:
<input id="myCheckbox" type="checkbox" checked="checked" />
稍后,在您的脚本中,
// handler
function onClickHandler (e) {
var i = 0, marker;
var visible = e.target.checked; // show if checked, otherwise hide
while (marker = markers[i++]) {
marker.setVisible(visible); // maps API hide call
}
}
// bind handler to checkbox.
document.getElementById('myCheckbox').onchange = onClickHandler;
供参考,请查看this fiddle。

概念很简单。只需为标记定义全局数组。推送所有标记和onchange事件显示/隐藏标记。结帐以下代码 小号@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ NI
