17
18                                         <input class="txt br2" name="ProvinceSelected" id="ProvinceSelected" type="text" size="30" value="@Model.Province" hidden>

二、JS部分

　　<script type="text/javascript" src="http://api.map.baidu.com/api?v=1.4"></script>
 1  <script type="text/javascript">
 2         // 百度地图API功能
 3         var map = new BMap.Map("l-map");            // 创建Map实例
 4         map.centerAndZoom(new BMap.Point(120.143814, 30.291648), 10);
 5         map.enableScrollWheelZoom();
 6         var local = new BMap.LocalSearch("全国", {
 7             renderOptions: {
 8                 map: map,
 9                 panel: "r-result",
10                 autoViewport: true,
11                 selectFirstResult: false
12             }
13         });
14         map.addEventListener("click", function (e) {
15
16             document.getElementById("longitude").value = e.point.lng;
17             document.getElementById("latitude").value = e.point.lat;
18         });
19         function getPoint() {
20             var city = document.getElementById("Address").value; // 初始化地图,设置城市和地图级别。
21             local.search(city);    //启用滚轮放大缩小
22             document.getElementById("demo").style.display = "";
23
24         }
25
26     </script>

三、CSS

1 <style type="text/css">
2 *{margin:0;padding:0;list-style-type:none;}
3 a,img{border:0;}
4 body{font:12px/180% Arial, Helvetica, sans-serif, "新宋体";}
5 .demo{width:850px;margin:20px auto;}
6 #l-map{height:400px;width:600px;float:left;border:1px solid #bcbcbc;}
