Google地图openInfoWindowHTML数组问题 [英] Google Maps openInfoWindowHTML array problem

问题描述

有人请帮忙解释一下为什么我不能使用这个工作？我正确地生成所有的位置，但是，它不会生成信息框。为什么会这样，有人可以帮我吗？

  var map = new GMap2（document.getElementById（map）） ; 
 map.addControl（新的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 />帮助台：+ wa_locations [i] [4] +）; 
}）; 
 
  

解决方案

你的观点，而不是你的标记。此外，从您的评论看来，你有一个JavaScript关闭问题。您可以使用 bindInfoWindowHtml 来避免侦听器和关闭>。下面是使用标记和bindInfoWindowHtml进行调整的最后部分：
$ b

  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）; 
} 
  

Could someone please help explain why I can't get this to work? I properly generates all the locations, however, it doesn't generate the info boxes. Why is this and can someone help me with it?

            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] +  "");
                });                     
            }   

解决方案

You are adding a listener to your point instead of to your marker. Further, from your comment it appears you have a JavaScript closure issue. You can avoid the listener and the closure by using bindInfoWindowHtml. Here's the last part tweaked to use the marker and 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); 
        }
