本文實例講述了php+js實作百度地圖多點標註的方法。分享給大家供大家參考，具體如下：
1.php建立json資料
$products = $this->product_db->select($where); $products_json = json_encode($products);
2.js傳入json資料
類似這樣的結構
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擅長處理json資料
<script>
var products_json = {$products_json};
// 百度地图
var citymap = new citymap(products_json,'宿迁');
