Removing a Marker in Google Maps API v3
提问by Nathan Campos
I'm trying to remove a markerthat was initialized like this:
我正在尝试删除一个像这样初始化的标记：
marker = new google.maps.Marker({
position: latLng,
map: map,
draggable: true,
animation: google.maps.Animation.DROP,
title: 'Marker 1',
icon: redPin
});
google.maps.event.addListener(marker, "click", function() {
showMarkerDialog(marker.position, "marker");
});
google.maps.event.addListener(marker, "dblclick", function() {
// Add a alert: Are you sure you want to remove this marker?
map.removeOverlay(marker);
});
Everything works perfectly except that when I double click it to remove what I get on the Error Console is this:
一切正常，除了当我双击它以删除我在错误控制台上得到的内容时：
TypeError: Object # has no method 'removeOverlay'
类型错误：对象 # 没有方法“removeOverlay”
What am I doing wrong?
我究竟做错了什么？

There is no removeOverlayfunction on the mapobject. Sounds like you've got only one marker, why use an array? Just change this:
地图对象上没有removeOverlay函数。听起来你只有一个标记，为什么要使用数组？只需改变这个：
google.maps.event.addListener(marker, "dblclick", function() {
map.removeOverlay(marker);
});
to this:
对此：
marker.addListener("dblclick", function() {
marker.setMap(null);
});
