ArcGIS Map SDK 去掉点击地图的黑色边框

设置样式，覆盖ArcGIS JS默认样式

.esri-view-surface--touch-none::after {
    outline: none !important;
}

完整代码如下：

<html lang="en">
  <head>
    <meta charset="utf-8" />
    <meta
      name="viewport"
      content="initial-scale=1,maximum-scale=1,user-scalable=no"
    />

        margin: 0;
        padding: 0;
      }
      /* 去除点击地图时的黑边框 */
      #viewDiv .esri-view-surface--touch-none::after {
        outline: none !important;
      }
    </style>
    <script>
      require([
        "esri/Map",
        "esri/views/MapView",
      ], (Map, MapView) => {


        const map = new Map({
          basemap: "gray-vector"
        });

        const view = new MapView({
          container: "viewDiv",
          map: map,
        });
      });
    </script>
  </head>
  <body>
    <div id="viewDiv"></div>
  </body>
