1. Lengkapkan kandungan dan tandai ikon berbeza mengikut jenis perniagaan yang berbeza (A, B, C, D, E) (selesai)
2 tatasusunan markerArr masing-masing, yetai Pada masa ini, kandungan titik penanda boleh muncul, tetapi ia akan sentiasa menjadi sekeping data terakhir dalam tatasusunan markerArr Bagaimanakah saya boleh memaparkan maklumat tatasusunan titik penanda yang sepadan selepas mengklik titik penanda?
Tolong beri saya nasihat, saya akan sangat berterima kasih, terima kasih.

Tidak kira anotasi yang diklik, maklumat terakhir akan dikeluarkan. Ini terutamanya soal skop.
Gunakan penutupan untuk menyelesaikan:
var createMark = function(lng, lat, info_html) {
var _marker = BMap.Marker baharu(BMap.Point(lng, lat).
"clickEListener ", function(e) {
this.openInfoWindow(new BMap.InfoWindow(info_html));
});
_marker.addEventListener("mouseover", function(e) { this.setTitle("at: " + lng + "," + lat);
});
kembalikan _penanda;
Letakkan latitud dan longitud serta maklumat paparan secara berasingan dalam fungsi tersebut.
