我有一张带有街景全景图,一个信息窗和一个可拖动标记的地图。拖动标记后,函数会请求getPanoramaByLocation查看视图服务是否可用。如果不是,那就关闭了信息窗口。这很好,但当我再次点击标记时,信息窗不再打开。你知道有什么问题吗? TX
var sv = new google.maps.StreetViewService();
function initialize() {
var optionMap = {
zoom: 13,
center: new google.maps.LatLng(47.390251,0.68882),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var myMap = new google.maps.Map(document.getElementById("mapDiv"), optionMap);
var optionsMarker = {
position: new google.maps.LatLng(47.390251,0.68882),
map: myMap,
draggable: true,
title: "my marker"
}
var marker = new google.maps.Marker(optionsMarker);
var infowindowDiv = '<div id="streetview" style="width:300px;height:200px;"' +'</div>';
var infoWindow = new google.maps.InfoWindow({
content: infowindowDiv,
position: myMap.getCenter() });
google.maps.event.addListener(marker, 'click', function() {
infoWindow.open(myMap, marker);
});
google.maps.event.addListener(infoWindow, 'domready', function() {
var panorama = new
google.maps.StreetViewPanorama(document.getElementById("streetview"));
panorama.setPosition(infoWindow.getPosition());
google.maps.event.addListener(marker, 'dragend', function(event) {
sv.getPanoramaByLocation(event.latLng, 50, processSVData);});
function processSVData(data, status) {
if (status == google.maps.StreetViewStatus.OK) {
var markerPanoID = data.location.pano;
// Set the Pano to use the passed panoID
panorama.setPano(markerPanoID);
panorama.setPov({
heading: 270,
pitch: 0,
zoom: 1
});
panorama.setVisible(true);
}
else {
infoWindow.close();
infoWindow = null;
};
}
});
}

来自GMaps API文档:
close() None Closes this InfoWindow by removing it from the DOM structure.
https://developers.google.com/maps/documentation/javascript/reference#InfoWindow
所以...如果你关闭了infowindow,它就消失了。永远。更是如此,如果你真的通过说“infoWindow = null;”来确定它已经消失了你必须做一个新的。我的建议是重构你的代码,以便有一个单独的函数,按需创建infowindow并返回它。在您的单击事件定义中,检查infowindow是否为null,如果是,则获取一个新的。

正如另一个答案所解释的那样,当用户点击关闭按钮时,信息框html将从DOM中删除,但JS对象仍在那里。
当你创建一个infowindow时,你必须调用open方法在地图上看到它
myInfoWindow.open(mymap);
所以,如果你听'closeclick'事件并保持infowindow状态
var infoWindowClosed = false;
google.maps.event.addListener(myInfoBox, "closeclick", function () {
infoWindowClosed = true;
});
您可以按需重新打开myInfoWindow
if(infoWindowClosed){
myInfoWindow.open(mymap);
}
