谷歌地图openInfoWindowHTML数组问题

Question

有人能帮我解释一下为什么我不能让它工作吗？我正确地生成了所有的位置，但是，它不会生成信息框。为什么会这样?有人能帮我吗？

            var map = new GMap2(document.getElementById("map"));
            map.addControl(new GSmallMapControl());
            map.addControl(new GMapTypeControl());
            map.setCenter(new GLatLng(47.6062, -122.3321), 8);
            var wa_locations = new Array(new Array("Seattle", "47.6062", "-122.3321", "###-###-####", "###-###-####"),
                                         new Array("Bellevue", "47.6104", "-122.2007", "###-###-####", "###-###-####"),
                                         new Array("Tacoma", "47.2529", "-122.4443", "###-###-####", "###-###-####"),
                                         new Array("Everett", "47.9790", "-122.2021", "###-###-####", "###-###-####"));
            for(var i = 0; i < wa_locations.length; i++)
            {
                var point = new GLatLng(wa_locations[i][1], wa_locations[i][2]);
                map.addOverlay(new GMarker(point)); 
                GEvent.addListener(point, "click", function()
                {
                    point.openInfoWindowHtml("<b>" + wa_locations[i][0] + "</b><br/>Sales: " + wa_locations[i][3] +  "<br/>Helpdesk: " + wa_locations[i][4] +  "");
                });                     
            }

您正在将侦听器添加到点，而不是添加到标记。此外，从你的评论来看，你似乎有一个JavaScript关闭的问题。您可以使用bindInfoWindowHtml来避免侦听器和闭包。下面是调整后的最后部分，使用了标记和bindInfoWindowHtml：

        for(var i = 0; i < wa_locations.length; i++)
        {
            var point = new GLatLng(wa_locations[i][1], wa_locations[i][2]);
            var marker = new GMarker(point);
            marker.bindInfoWindowHtml("<b>" + wa_locations[i][0] + "</b><br/>Sales: " + wa_locations[i][3] +  "<br/>Helpdesk: " + wa_locations[i][4] +  "");
            map.addOverlay(marker); 
        }
