【百度地圖】製作多途經點的線路導航,模擬運動 (vue,typescript)

 

網上有從起點到終點的模擬線路和運動,途經點的比較少。 結合網上demo,再進行了一下修改。

VUE (Typescript),先在index.html裡引用

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width,initial-scale=1.0">
    <link rel="icon" href="<%= BASE_URL %>favicon.ico">
    <title>得了麼得</title>
    <script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=你的KEY"></script>
  </head>
  <body>
    <noscript>
      <strong>We're sorry but tl_screen doesn't work properly without JavaScript enabled. Please enable it to continue.</strong>
    </noscript>
    <div id="app"></div>
    <!-- built files will be auto injected -->
  </body>
</html>

然後宣告, typescript裡引用圖片,需要require,不然會預設是百度的圖片地址。

declare const BMap: any;
declare function require(iconUrl: string): string;

@Component
export default class MapScreen extends Vue { 

}

 

private loadMap() {
        const that = this;
        const map = new BMap.Map('baidu-map');
        map.clearOverlays();
        map.enableScrollWheelZoom();
        map.centerAndZoom(new BMap.Point(113.044643, 28.169439), 15);

        map.setMapStyle({ // 可以自己定義地圖底圖 http://developer.baidu.com/map/custom/
            styleJson:[
