所以我创建了一个jsFiddle来演示我的问题:http://jsfiddle.net/6vpc2/1/ 将鼠标悬停在我的jsFiddle中的标记上可以看到InfoWindow的位置。
我有一个GoogleMap"对象"创建谷歌地图。创建Google Map之后:
var mapOptions = {
zoom: 8, // The initial zoom level when your map loads (0-20)
minZoom: 6, // Minimum zoom level allowed (0-20)
maxZoom: 17, // Maximum soom level allowed (0-20)
zoomControl: true, // Set to true if using zoomControlOptions below, or false to remove all zoom controls.
zoomControlOptions: {
style: google.maps.ZoomControlStyle.DEFAULT // Change to SMALL to force just the + and - buttons.
},
//center: location, // Centre the Map to our coordinates variable
mapTypeId: google.maps.MapTypeId.ROADMAP, // Set the type of Map
scrollwheel: false, // Disable Mouse Scroll zooming (Essential for responsive sites!)
// All of the below are set to true by default, so simply remove if set to true:
panControl: false, // Set to false to disable
mapTypeControl: false, // Disable Map/Satellite switch
scaleControl: false, // Set to false to hide scale
streetViewControl: false, // Set to disable to hide street view
overviewMapControl: false, // Set to false to remove overview control
rotateControl: false // Set to false to disable rotate control
}
if (this.instances.length > 0) {
return this.instances.pop();
}
var googleMap = new GoogleMap();
googleMap.map = new google.maps.Map(googleMap.mapCanvas, mapOptions);
return googleMap;
然后我在JS"对象"中设置var。到返回的googleMap值。
然后我使用this.map,即上面代码中返回的googleMap,在地图上设置标记:
this.latitude = latitude;
this.longitude = longitude;
var location = new google.maps.LatLng(latitude, longitude);
var infowindow = new google.maps.InfoWindow({
content: placeMarkerContent
});
this.marker = new google.maps.Marker({
position: location,
map: this.map,
});
this.map.setCenter(location);
google.maps.event.addListener(this.marker, 'mouseover', function () {
infowindow.open(this.map, this.marker);
});
google.maps.event.addListener(this.marker, 'mouseout', function () {
infowindow.close(this.map, this.marker);
});
问题是InfoWindow没有显示在Marker上方,请参阅我的jsFiddle:http://jsfiddle.net/6vpc2/1/ 将鼠标悬停在我的jsFiddle中的标记上可以看到InfoWindow的位置。
答案 0 :(得分:1)
this.marker未定义。在单击侦听器函数内部,“this”是标记。
google.maps.event.addListener(this.marker, 'mouseover', function () {
infowindow.open(this.getMap(), this);
});
