我应该首先说我对javascript或Google API V3了解不多。无论如何,我一直在尝试包含带有标记的谷歌地图,以指示我访问过infowindow的地方。我在互联网上找到了一个复制到我页面的例子。然后,我尝试添加一个功能,以便在单击标记时放大到该位置。更改代码后,我设法让缩放工作变得非常好。但是,infowindow不会打开。在我使用它之前它开放之前;
infowindow.setContent(contentString);
infowindow.open(map,marker);.
但缩放功能无法正常工作。更改为此后;
infowindow.setContent(this.html);
infowindow.open(map, this);
缩放效果很好。但是我失去了信息。任何人都可以看到我如何更改代码,使缩放和infowindow工作。如果有人能帮助我,我会很高兴。我可以使用下面的代码进行调整,还是需要完全重写?感谢提前

主要问题是您更改了代码以使用标记的.html属性(google.maps.Marker对象没有.html属性,但您可以添加它们。)
修复它的2个选项:
使用原始代码:
// A function to create the marker and set up the event window function
function createMarker(latlng, name, html) {
var contentString = html;
var marker = new google.maps.Marker({
position: latlng,
map: map,
zIndex: Math.round(latlng.lat() * -100000) << 5
});
google.maps.event.addListener(marker, 'click', function () {
infowindow.setContent(contentString);
infowindow.open(map,marker);
map.setZoom(10);
map.setCenter(marker.getPosition());
});
// save the info we need to use later for the side_bar
gmarkers.push(marker);
// add a line to the side_bar html
side_bar_html += '<a href="javascript:myclick(' + (gmarkers.length - 1) + ')">' + name + '<\/a><br>';
}
将.html添加到google.maps.Marker并使用this
:
// A function to create the marker and set up the event window function
function createMarker(latlng, name, html) {
var marker = new google.maps.Marker({
position: latlng,
map: map,
html: html, // <---------------------------------------------- add this to the Marker
zIndex: Math.round(latlng.lat() * -100000) << 5
});
google.maps.event.addListener(marker, 'click', function () {
infowindow.setContent(this.html);
infowindow.open(map,this);
map.setZoom(10);
map.setCenter(this.getPosition());
});
// save the info we need to use later for the side_bar
gmarkers.push(marker);
// add a line to the side_bar html
side_bar_html += '<a href="javascript:myclick(' + (gmarkers.length - 1) + ')">' + name + '<\/a><br>';
}

默认情况下,API将平移地图,以便infowindow完全可见(如果可能)。
这将通过使用动画来完成,当您设置缩放+中心并且将覆盖您的设置时,此动画仍在运行。
将 disableAutoPan
- infowindow
选项设置为 true
以禁用自动平移,它应该按预期工作< / p>
