Question

im currenty undataking一个包含谷歌地图API的项目！我使用我的数据库中的mysql在地图上加载标记。现在我想要完成的事情是我在http://www.tanesco.co.tz/index.php?option=com_wrapper&view=wrapper&Itemid=155

之前看到过的

我想在显示的表格上创建一个链接，点击它时会在地图上打开一个信息窗口......我完全不知道从哪里开始

这是我的地图代码

    <?php include("connect.php"); 

?>
<!DOCTYPE html >
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<link href="stylesheet.css" type="text/css" rel="stylesheet" media="screen" />
<title>AzamTv Customer Database</title>
<style type="text/css">
<!--
.style2 {color: #999999}
.style3 {color: #666666}
.style4 {color: #FF0000}
.style5 {color: #3366FF}

Answer 1

您可以创建

等标记

var marker = new google.maps.Marker({
            position: myLatlng,
            title:"Your title"
        });

创建点击触发器上的链接

infowindow.open(map,marker);

我猜这就是全部。

编辑：您可以确定需要通过href-parameter

显示哪个标记

我想从桌面上的链接打开地图infowindow
