javascript 開發百度地圖
問題描述
javascript 開發百度地圖
1、完成內容，按照不同業態類型（A,B,C,D,E），標注不同圖標（完成）
2、點擊標注點分別彈出markerArr數組內的title，yetai等內容目前可以彈出標注點內容，但是永遠都是markerArr數組內的最后一條數據，請問應該怎樣才可以點擊標注點后彈出對應的標注點數組信息。
求大神指點，感激不盡，謝謝。

回答2：不管點擊哪一個標注，都是輸出最后一條的信息。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("位于: " + lng + "," + lat);
});
return _marker;
將經緯度，和顯示信息單獨放在函數里，new標注之后，立刻加監聽。
