我正在尝试使用 DirectionsRenderer 来显示没有路线列表的 DirectionsResult。根据 API 版本 3 文档，DirectionsRendererOptions 对象有一个“hideRouteList”属性，当设置为 true 时应该隐藏路由列表。我无法让它工作。这是一个错误还是我只是没有正确编码？以下是我的代码。

<html>
<head>
<title>Driving Directions</title>
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false">    </script>
<script type="text/javascript">
<!--
function initialize() {
    var dirService = new google.maps.DirectionsService();
    var dirRequest = {
          origin: "350 5th Ave, New York, NY, 10118",
          destination: "1 Wall St, New York, NY",
          travelMode: google.maps.DirectionsTravelMode.DRIVING,
          unitSystem: google.maps.DirectionsUnitSystem.IMPERIAL,
          provideTripAlternatives: true
    };
    dirService.route(dirRequest, showDirections);
}

function showDirections(dirResult, dirStatus) {
    if (dirStatus != google.maps.DirectionsStatus.OK) {
        alert('Directions failed: ' + dirStatus);
        return;
    }
    var rendererOptions = {
        hideRouteList: true
    };
    var dirRenderer = new google.maps.DirectionsRenderer(rendererOptions);  
    dirRenderer.setPanel(document.getElementById('dir-container'));
    dirRenderer.setDirections(dirResult);
}
-->
</script>
</head>
<body onLoad="initialize();">
<div id="dir-container"></div>

我试过了，我不认为你做错了什么。看起来这个选项被破坏了。我在已知问题中找不到它，所以我认为这是一个新问题。有机会我会写的。

我认为您误解了文档，或者我误解了您的问题！

hideRouteList:true 隐藏路线选项，而不是路线标记。这仅适用于在您也提供的请求对象上设置 provideRouteAlternatives: true 。

下面是我的快速测试。将 hideRouteList 设置为 true/false 以查看下面路线标记的差异。就我而言，没有路线选项，但它确实有不同的标记。
