如何在谷歌地图中显示多个标记与制造商有自己的信息窗口

Question

我想在谷歌地图中显示多个标记，制造商有自己的信息窗口。问题是，当我单击任一标记时，只会出现一个信息窗口（我点击不显示的标记的信息窗口）。还有一个问题是当信息窗口出来时，它不顺畅（有像后面还出现了一个盒子白盒子）

// map center
var center = new google.maps.LatLng(2.855262784366583, 105.4302978515625);

// marker position
//var factory = new google.maps.LatLng(2.855262784366583, 105.4302978515625);

function initialize() {
  var mapOptions = {
    center: center,
    zoom: 7,
    mapTypeId: google.maps.MapTypeId.ROADMAP

  };

         // Create a <script> tag and set the USGS URL as the source.
         var script = document.createElement('script');
         // This example uses a local copy of the GeoJSON stored at
         // http://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/2.5_week.geojsonp
         script.src = 'https://developers.google.com/maps/documentation/javascript/examples/json/earthquake_GeoJSONP.js';
         document.getElementsByTagName('head')[0].appendChild(script);
  var map = new google.maps.Map(document.getElementById("map-canvas"),mapOptions);

  // Loop through the results array and place a marker for each
     // set of coordinates.
     window.eqfeed_callback = function(results) {
       for (var i = 0; i < results.features.length; i++) {
         var coords = results.features[i].geometry.coordinates;
         var latLng = new google.maps.LatLng(coords[1],coords[0]);
         var marker = new google.maps.Marker({
           position: latLng,
           map: map
         });

           var iwBackground = iwOuter.prev();

最简单的代码修复。更改：

 // This event expects a click on a marker
 // When this event is fired the Info Window is opened.
 google.maps.event.addListener(marker, 'click', function() {
   infowindow.open(map,marker);
 });

至：

 google.maps.event.addListener(marker, 'click', function() {
   infowindow.open(map,this);
 });

标记点击功能中的this是标记。

这将使InfoWindow在点击的标记上打开。但据我所知，所有InfoWindows都有相同的内容，这不是很有用。
