本文实例讲述了php+js实现百度地图多点标注的方法。分享给大家供大家参考，具体如下：
1.php创建json数据
|
1
2
|
$products = $this->product_db->select($where);$products_json = json_encode($products); |
2.js传入json数据
类似于这样的结构

var markerArr = [{ title: "名称：广州火车站", point: "113.264531,23.157003", address: "广东省广州市广州火车站", tel: "12306"}, { title: "名称：广州塔（赤岗塔）", point: "113.330934,23.113401", address: "广东省广州市广州塔（赤岗塔） ", tel: "18500000000"}, { title: "名称：广州动物园", point: "113.312213,23.147267", address: "广东省广州市广州动物园", tel: "18500000000"}, { title: "名称：天河公园", point: "113.372867,23.134274", address: "广东省广州市天河公园", tel: "18500000000"}]; |
js擅长处理json数据

<script>var products_json = {$products_json};// 百度地图var citymap = new citymap(products_json,'宿迁');</script> |
