1.函数式编程
//创建和初始化地图函数：function initMap(){createMap();//创建地图setMapEvent();//设置地图事件addMapControl();//向地图添加控件}//创建地图函数：function createMap(){var map = new BMap.Map("dituContent");//在百度地图容器中创建一个地图var point = new BMap.Point(116.411024,39.910286);//定义一个中心点坐标map.centerAndZoom(point,13);//设定地图的中心点和坐标并将地图显示在地图容器中var marker = new BMap.Marker(point); // 创建标注map.addOverlay(marker); // 将标注添加到地图中marker.setAnimation(BMAP_ANIMATION_BOUNCE); //跳动的动画window.map = map;//将map变量存储在全局}//地图事件设置函数：function setMapEvent(){map.enableDragging();//启用地图拖拽事件，默认启用(可不写)map.enableScrollWheelZoom();//启用地图滚轮放大缩小map.enableDoubleClickZoom();//启用鼠标双击放大，默认启用(可不写)map.enableKeyboard();//启用键盘上下左右键移动地图}//地图控件添加函数：function addMapControl(){//向地图中添加缩放控件var ctrl_nav = new BMap.NavigationControl({anchor:BMAP_ANCHOR_TOP_LEFT,type:BMAP_NAVIGATION_CONTROL_LARGE});map.addControl(ctrl_nav);//向地图中添加缩略图控件var ctrl_ove = new BMap.OverviewMapControl({anchor:BMAP_ANCHOR_BOTTOM_RIGHT,isOpen:1});map.addControl(ctrl_ove);//向地图中添加比例尺控件var ctrl_sca = new BMap.ScaleControl({anchor:BMAP_ANCHOR_BOTTOM_LEFT});map.addControl(ctrl_sca);}initMap();//创建和初始化地图2.改造
function mapmark(lng, lat, zoom){this.lng = lng;this.lat = lat;this.zoom = zoom;this.initMap = function() {this.createMap();//创建地图this.setMapEvent();//设置地图事件this.addMapControl();//向地图添加控件};this.createMap = function() {var map = new BMap.Map("dituContent");//在百度地图容器中创建一个地图var point = new BMap.Point(this.lng,this.lat);//定义一个中心点坐标map.centerAndZoom(point,this.zoom);//设定地图的中心点和坐标并将地图显示在地图容器中var marker = new BMap.Marker(point); // 创建标注map.addOverlay(marker); // 将标注添加到地图中marker.setAnimation(BMAP_ANIMATION_BOUNCE); //跳动的动画window.map = map;//将map变量存储在全局};this.setMapEvent = function() {map.enableDragging();//启用地图拖拽事件，默认启用(可不写)map.enableScrollWheelZoom();//启用地图滚轮放大缩小map.enableDoubleClickZoom();//启用鼠标双击放大，默认启用(可不写)map.enableKeyboard();//启用键盘上下左右键移动地图};this.addMapControl = function() {//向地图中添加缩放控件var ctrl_nav = new BMap.NavigationControl({anchor:BMAP_ANCHOR_TOP_LEFT,type:BMAP_NAVIGATION_CONTROL_LARGE});map.addControl(ctrl_nav);//向地图中添加缩略图控件var ctrl_ove = new BMap.OverviewMapControl({anchor:BMAP_ANCHOR_BOTTOM_RIGHT,isOpen:1});map.addControl(ctrl_ove);//向地图中添加比例尺控件var ctrl_sca = new BMap.ScaleControl({anchor:BMAP_ANCHOR_BOTTOM_LEFT});map.addControl(ctrl_sca);};
}调用
var mapmark = new mapmark(116.411024,39.910286,13);
