<script type= "text/javascript" src= "http://api.map.baidu.com/api?v=2.0&ak=HR3RRyTsXYdQ3QzzG5yUkg0q" ></script> <script type= "text/javascript" src= "http://developer.baidu.com/map/jsdemo/demo/convertor.js" ></script> |
这个是MUI封装好的JS,可用来调用移动设备底层功能:

|
<script src= "../js/mui.min.js" ></script> |
HTML代码:

< div id="allmap"> 地图加载中... </ div > |
JS调用底层:

mui.plusReady( function (){ plus.geolocation.getCurrentPosition(translatePoint, function (e){ mui.toast( "异常:" + e.message); }); }); |
最核心的部分,创建地图并且转换坐标:

function translatePoint(position){ var currentLon = position.coords.longitude; var currentLat = position.coords.latitude; var gpsPoint = new BMap.Point(currentLon,currentLat); BMap.Convertor.translate(gpsPoint,2,initMap); //坐标转换 } function initMap(point){ map = new BMap.Map( "allmap" ); //创建地图 map.addControl( new BMap.NavigationControl()); map.addControl( new BMap.ScaleControl()); map.addControl( new BMap.OverviewMapControl()); map.centerAndZoom(point,15); map.addOverlay( new BMap.Marker(point)); |
