媒介:百度舆图是网页中运用舆图的经常运用第三方对象,这里连系React项目中学到的运用场景总结一些运用要点。

一、在网页中嵌入百度舆图

  • 搜百度舆图开放平台,注册百度开辟者账号
  1. 控制台:检察运用、建立运用(取得百度舆图密钥)
  2. 开辟文档:挑选JavaScriptAPI

    Referer白名单:*   (比方*.tedu.cn  域名只能有这个字段,能力运用这个密钥,制止因盗用密钥运用本身网站的效劳)

  • 建立一个网站:登录百度舆图开辟者平台,为网站请求一个舆图的AccesKey(环球独一网站密钥)

  • 在本身的网页中嵌入百度舆图供应的API,嵌入百度舆图
  1. 引入一个特别的script,症结安排密钥的处所:
    <script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=你的密钥"></script>
  2. 中央代码:

    var map = new BMap.Map("container");  //建立舆图实例
    var point = new BMap.Point(116.300829, 39.915836); //建立点坐标(天安门坐标为例)
    map.centerAndZoom(point, 17); //以指定点为中央并缩放 (17透露表现层级)
    
  • 经常运用控件:可能会变,不消记,查文档便可

  1. 启用滚轮缩放要领:map.enableScrollWheelZoom(true);

  2. 增加导航控件:map.addControl(new BMap.NacigationControl());

  3. 增加缩放控件:map.addControl(new BMap.ScalControl());

  4. 增加概览图控件:map.addControl(new BMap.OverviewMapControl()); 

  5. 增加舆图范例控件:map.addControl(new BMap.MapTypeControl()); 

  • 经常运用掩盖物:小符号/小申明/小页签

    var mk = new BMap.Marker(point);
    map.addOverlay(mk);
    marker.setAnimation(BMap)ANIMATION_BOUNCE); //弹跳动画
    

      

二、绘制定单舆图

  • 建立ak,加载百度舆图sdk:【百度舆图开辟平台】

  • 舆图初始化:public->index.html中引入百度舆图第三方JS库

    <title>React App</title>
    <!--第三方库 百度舆图-->
    <script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=vALBxRpSKdoPxLyDcuMQPWFL8avoRTP0"></script>
    

    pages->order->detail.js中:挪用new window.BMap.Map('id')初始化Map

    //初始化舆图
    renderMap = (list) => {
            this.map = new window.BMap.Map('orderDetailMap');
            // this.map.centerAndZoom('北京', 11)
            //增加舆图控件
            this.addMapControl();
            //挪用路线图绘制要领
            this.drawBikeRoute(list.position_list);
            //挪用效劳区绘制要领
            this.drawServiceArea(list.area);
    }
    

    注重:单页面运用必需挪用window.BMap全局变量能力辨认BMap,不然会报错no defined;多页面运用中直接运用new BMao.Map('id')便可

  • 增加舆图控件

    //增加舆图控件 
    addMapControl = () => {
            let map = this.map;
            map.addControl(new window.BMap.ScaleControl({ anchor: window.BMAP_ANCHOR_TOP_RIGHT }));
            map.addControl(new window.BMap.NavigationControl({ anchor: window.BMAP_ANCHOR_TOP_RIGHT }));
    }
  • 绘制用户行驶路线

    //绘制用户行驶路线图
