php实现地图区域数据统计-ajax载入数据

<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript" src="raphael.js"></script>
<script type="text/javascript" src="chinamapPath.js"></script>

然后在body中需要放置地图的位置放置div#map。

<div id="map"></div>

$host="localhost";//主机
$db_user="root";//数据库用户名
$db_pass="";//密码
$db_name="demo";//数据库名称
 
$link=mysql_connect($host,$db_user,$db_pass);//连接数据库
mysql_select_db($db_name,$link);
mysql_query("SET names UTF8");
 
$sql = "select active from mapdata order by id asc";//查询
$query = mysql_query($sql);
 
while($row=mysql_fetch_array($query)){
    $arr[] = $row['active'];
}
echo json_encode($arr);//JSON格式
mysql_close($link);//关闭连接

$(function(){
    $.get("json.php",function(json){
        ...
    });
});

function string2Array(string) { 
    eval("var result = " + decodeURI(string)); 
    return result; 
}
