谷歌地图API:标记颜色的条件

Google Maps API: condition on Marker color

本文关键字：颜色 条件 API 谷歌地图      更新时间：2023-09-26

我正在尝试对谷歌地图标记的颜色设置条件。

我试过类似的东西：

        if (name == 'name') {
        icon: image2
        }

但是地图不再显示了，我不知道如何调试它。

以下是完整的脚本：

<script type="text/javascript">
function load() {
  var map = new google.maps.Map(document.getElementById("map"), {
    center: new google.maps.LatLng(<?= json_encode($lat); ?>, <?= json_encode($lng);?>),
    zoom: <?php echo json_encode($zoom); ?>,
    mapTypeId: 'roadmap'
  });
  var infoWindow = new google.maps.InfoWindow;
  // Change this depending on the name of your PHP file
  downloadUrl(<?= json_encode($url); ?>, 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 image1 = 'http://labs.google.com/ridefinder/images/mm_20_blue.png';
      var image2 = 'http://labs.google.com/ridefinder/images/mm_20_red.png';
      var marker = new google.maps.Marker({
        map: map,
        position: point,

     if (name == 'name') {
        icon: image2
        }
      });
      hover(marker,i);
      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 hover(marker, i){
document.getElementById('a'+i).onmouseover = function() {
   marker.setIcon('http://labs.google.com/ridefinder/images/mm_20_red.png');
}
document.getElementById('a'+i).onmouseleave = function() {
   marker.setIcon('http://labs.google.com/ridefinder/images/mm_20_blue.png');
}
}

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() {}

任何帮助都将不胜感激！

尝试这种方法：

var marker = new google.maps.Marker({
        map: map,
        position: point,
});
 if (name == 'name') {
 marker.setIcon('image2');
}
else{
 marker.setIcon('image1');
}
