Question

我正在使用Google的mysql / ajax / php地图搜索示例。我想用css设置信息窗口的样式，但它不起作用。这是示例代码

<!DOCTYPE html >
  <head>
    <meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
    <meta http-equiv="content-type" content="text/html; charset=UTF-8"/>
    <title>PHP/MySQL & Google Maps Example</title>
    <script src="https://maps.googleapis.com/maps/api/js?key=xxxxxxxxxxxx"
            type="text/javascript"></script>
    <script type="text/javascript">

    var customIcons = {
      Event_Organisers: {
        icon: 'http://labs.google.com/ridefinder/images/mm_20_blue.png'
      } 
    };

    var map = null, marker = null;

    function load() {
      var map = new google.maps.Map(document.getElementById("map"), {
        center: new google.maps.LatLng(17.4121,78.1278),
        zoom: 13,
        mapTypeId: 'roadmap'

      });
      var infoWindow = new google.maps.InfoWindow;
      // Change this depending on the name of your PHP file
      downloadUrl("xmloutput.php", function(data) {
        var xml = data.responseXML;
        var markers = xml.documentElement.getElementsByTagName("marker");
        for (var i = 0; i < markers.length; i++) {
          var name = markers[i].getAttribute("name");
          var address = markers[i].getAttribute("address");
          var type = markers[i].getAttribute("type");
          var point = new google.maps.LatLng(
              parseFloat(markers[i].getAttribute("lat")),
              parseFloat(markers[i].getAttribute("lng")));
          var html = "<b>" + name + "</b> <br/>" + address;
          var icon = customIcons[type] || {};
          var marker = new google.maps.Marker({
            map: map,
            position: point,
            icon: icon.icon
          });
          bindInfoWindow(marker, map, infoWindow, html);
        }
      });
    }

    function bindInfoWindow(marker, map, infoWindow, html) {
      google.maps.event.addListener(marker, 'click', function() {
        infoWindow.setContent(html);
        infoWindow.open(map, marker);


      });
    }

    function downloadUrl(url, callback) {
      var request = window.ActiveXObject ?
          new ActiveXObject('Microsoft.XMLHTTP') :
          new XMLHttpRequest;

      request.onreadystatechange = function() {
        if (request.readyState == 4) {
          request.onreadystatechange = doNothing;
          callback(request, request.status);
        }
      };

      request.open('GET', url, true);
      request.send(null);
    }

    function doNothing() {}

    //]]>

  </script>
 <style>

 </style>
  </head>

  <body onload="load()">
    <div id="map" style="width: 550px; height: 250px;"></div>
  </body>

</html>

有什么方法可以使用css或javascript设置样式信息窗口。

请参阅以下css

.infoWindow {
    display:none;
}
.infoWindow {
    border:2px solid black;
    margin-top: 8px;
    background:#333;
    color:#FFF;
    font-family:Arial, Helvetica, sans-serif;
    font-size:12px;
    padding: .5em 1em;
    -webkit-border-radius: 2px;
    -moz-border-radius: 2px;
    border-radius: 2px;
    text-shadow:0 -1px #000000;
    -webkit-box-shadow: 0 0  8px #000;
    box-shadow: 0 0 8px #000;
}

假设您申请了您的课程＆＃39; infoWindow＆＃39;正确地到你的地图元素，我认为发生的事情是你的CSS类被来自Google API的load（）函数的响应中的CSS覆盖。

如果您将Chrome用作浏览器，请右键点击您的元素＆＃39; infoWindow＆＃39;并选择＆＃39;检查＆＃39; （页面加载后）。

如果您没有在那里看到预期的CSS属性，那么您需要在加载地图后应用自定义CSS。例如，JQuery有一个函数：https://api.jquery.com/addclass/
