The main purpose is to reference the custom of covering in Baidu map, the path is again under the asset / images / folders, direct reference error. Need to re-import the references.
In the <script> </ script> tags added as follows:
1 import gisGreen from '../assets/images/GIS_Green2.png'; 2 export default {…… 3 methods:{ 4 ……, 5 handler ({BMap, map}) { 6 var point = new BMap.Point(120.66, 31.20); 7 map.centerAndZoom(point, 13); 8 var myIcon = new BMap.Icon(gisGreen, new BMap.Size(20, 32)); 9 var marker = newBMap.Marker (Point, {icon: myIcon}); // create a label 10 the Map.addOverlay (marker); // be added to the map labels 11 } 12 } 13 } 14
