Google地图V3将中心设置为特定标记 [英] Google map V3 Set Center to specific Marker

问题描述

我使用Google Map V3显示使用MYsql和PHP从数据库中提取的标记列表。
由于我没有Long，Lat信息
，所以我的标记在地图上使用完整地址（来自DB，包括邮编）设置。所有工作正常，MY循环看起来如下

I am using Google Map V3 to display a list of markers pulled from a DB, using MYsql and PHP. MY markers are set on the map using the full address (from DB, including postcode) as I don't have the Long,Lat info All is working fine, MY loop looks as follow

while...
Addmarker(map,'MY ADdress','Title');
end while;

现在我想将地图设置为循环中包含的特定标记，输入邮编。
如何设置地图为中心并打开infowindow？

Now I would like to set the map to a specific marker contained in the loop that will match a previously entered postcode. How can I set the map to center to this marker and open the infowindow?

推荐答案

地图，您可以通过API检索纬度/经度坐标，并使用它来设置地图的中心。您首先需要确定您希望集中哪个标记 - 我会将其留给您。

Once you have markers on the map, you can retrieve the Lat/Long coordinates through the API and use this to set the map's center. You'll first just need to determine which marker you wish to center on - I'll leave that up to you.

// "marker" refers to the Marker object you wish to center on

var latLng = marker.getPosition(); // returns LatLng object
map.setCenter(latLng); // setCenter takes a LatLng object

信息窗口是单独的对象，通常绑定到一个标记，所以打开信息窗口，你可能会做这样的事情（但它取决于你的代码）：

Info windows are separate objects which are typically bound to a marker, so to open the info window you might do something like this (however it will depend on your code):

var infoWindow = marker.infoWindow; // retrieve the InfoWindow object
infoWindow.open(map); // Trigger the "open()" method

希望这有助于您。
