下面的代码应该生成一个谷歌地图并从MySQL数据库中检索标记并在地图上绘制它们。相反，我得到一个没有错误的空白页面，当查看源代码时，所有addMarker点都在那里回显。我究竟做错了什么？我尝试将最终的php db查询部分移动到JS部分的外部，最终将addMarker db结果回显到实际页面，而不仅仅是在源中可见。
<?php
$dbname ='edited out'; //Name of the database
$dbuser ='edited out'; //Username for the db
$dbpass ='edited out'; //Password for the db
$dbserver ='edited out'; //Name of the mysql server
$dbcnx = mysql_connect ("$dbserver", "$dbuser", "$dbpass");
mysql_select_db("$dbname") or die(mysql_error());

您的地图没有尺寸。你在css中有这个：
#map_canvas { height: 100%; }
然而你的＆＃34;地图＆＃34; div有id＆＃34; map＆＃34;。那应该是：
#map { height: 100%; }

看起来你正在制作地图的中心0,0。尝试使用latlgn的中心值初始化地图。
