我想在嵌入式地图下方的网页上添加一行文字,说明当前地图上有多少针......“此地图目前有XX个针脚。” 我想让XX自动填写当前号码。这就是标记信息的存储方式..
var locations = [
[' place a ', 21.81821, 63.84583, 0.000000 ],
[' place b ', 34.56343, 67.89073, 0.000000 ]];
和标记创建并聚集在这里
var markers = [];
var marker, i;
for (i = 0; i < locations.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][1], locations[i][2]),
map: map
});
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infowindow.setContent(locations[i][0]);
infowindow.open(map, marker);
}})(marker, i));
markers.push(marker)}
var markerCluster = new MarkerClusterer(map, markers,{gridSize:40});}
google.maps.event.addDomListener(window, 'load', initialize);
我想也许document.write可以自动调用元素的长度(位置/标记/标记...),如下所示
.
.
var XX = locations.length
<div id="map"></div>
<script language="javascript" type="text/javascript">
document.write("the map currently has", [XX], "pins");
</script>
但我无法实现它,使用示例位置,读出会说“地图当前有 2 引脚”

MarkerClusterer有一个getTotalMarkers()
函数,可以返回群集中的标记总数 - 无需重新发明轮子...
如果我理解正确,应工作(未经测试,我会尽快检查):
//assumes an element with an id of marker-counter that you want to output to
document.getElementById("marker-counter").innerHTML = "the map currently has" + markerCluster.getTotalMarkers() + "pins";

你试过了吗?
document.write("the map currently has " + XX + " pins");
我认为没有理由不这样做。
