javascript 開發百度地圖

1、完成內容,依照不同業態類型(A,B,C,D,E),標註不同圖示(完成)

2、點選標註點分別彈出markerArr數組內的title,yetai等內容目前可以彈出標註點內容,但是永遠都是markerArr數組內的最後一條數據,請問應該怎樣才可以點擊標註點後彈出對應的標註點數組信息。

求大神指點,感激不盡,謝謝。

不管點擊哪一個標註,都是輸出最後一條的訊息。這主要是作用域的問題。

用閉包解決:

var createMark = function(lng, lat, info_html) {

 var _marker = new BMap.Marker(new BMap.Point(lng, lat));

 _marker.addEventListener("click", function(e) {

 this.openInfoWindow(new BMap.InfoWindow(info_html));

 }) ;

 _marker.addEventListener("mouseover", function(e) { this.setTitle("位於: " lng "," lat);

 });

# return _marker;

將經緯度,和顯示訊息單獨放在函數裡,new標註之後,立刻加監聽。
