Question

我目前正在开展一个项目，该项目涉及在地图上绘制大量自定义标记，然后在点击时创建弹出页面。我有这个问题，作为javascript的新手正在获得第二个标记图像显示在地图上。到目前为止，我有以下代码，如你所见，'相机'图标有效...但需要'caltex'才能工作......：

<html>
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=true"></script>
<script type="text/javascript">
  function initialize() {
    var latlng = new google.maps.LatLng(-43.54654110763488, 172.6156002235225);
    var myOptions = {
      zoom: 11,
      center: latlng,
      navigationControl: false,
      scaleable: false,
      draggable:false,


      navigationControlOptions: {style: google.maps.NavigationControlStyle.ANDROID,position: google.maps.ControlPosition.TOP_LEFT},
      mapTypeId: google.maps.MapTypeId.ROADMAP


    };
    var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);


  setMarkers(map, webcams, caltex);
  }

看起来您已将标记逻辑封装到setMarkers（）中，以便您可以为每种类型的标记调用一次。但是你只调用一次。你需要

setMarkers(map, webcams);
setMarkers(map, caltex);
