我有以下代码:

<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />

<script src="http://code.jquery.com/jquery-latest.min.js"></script>
<script type="text/javascript">
function initialize() {
var cities = {{json|safe}};
/*

} /* */
var center = new google.maps.LatLng(-22.784791,-45.088806);
var myOptions = {
zoom: 8,
center: center,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var citiesLoc = new Array();
// var flightPlanCoords = new Array();
var infoBoxes = new Array();
var markers = new Array();
for (var i in cities) {
// document.write(cities[i]['fields']['name'] );
citiesLoc[i] = new google.maps.LatLng(cities[i]['fields']['x'],cities[i]['fields']['y']);
// flightPlanCoords.push(new google.maps.LatLng(cities[i]['fields']['x'],cities[i]['fields']['y']));
infoBoxes[i] = new google.maps.InfoWindow({

});
markers[i] = new google.maps.Marker({

});
google.maps.event.addListener(markers[i], 'click', function() {
infoBoxes[i].open(map, markers[i]);
});
};
// document.write(infoBoxes[1]['content']);
/*

它设置了两个标记，并附加了两个信息窗口，但是当我单击任一标记时，仅显示其中一个标记(2 号中的第 1 号，零索引)。如果我这样写:
google.maps.event.addListener(markers[0], 'click', function() {
infoBoxes[0].open(map, markers[0]);
});
google.maps.event.addListener(markers[1], 'click', function() {
infoBoxes[1].open(map, markers[1]);
});
然后就可以正常工作了。我错过了什么？
最佳答案
当 infoBoxes[i].open(map,markers[i]); 在函数内部求值时，它将采用 i 的更新值，即后面的值循环结束，即 1。
只需在其中执行 alert(i) 即可看到这种情况发生。
这是一个粗略的修复(经过测试且有效):
markers[i]._index = i;
google.maps.event.addListener(markers[i], 'click', function() {
infoBoxes[this._index].open(map, markers[this._index]);
});
您可能应该在这里阅读更多内容 http://code.google.com/apis/maps/documentation/javascript/events.html 。我知道要读的东西很多，但有时是必要的。
关于javascript - Google Maps API - 无法在多个标记上设置多个 infoWindows，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/3999074/
