更改路线中标记的默认图标

我想在两个位置之间搜索路线时更改标记的默认图标。我该怎么做？我用这个代码，但没有途径我没有得到的只是地图，并指出更改路线中标记的默认图标

var start = new google.maps.Marker({ 
position: new google.maps.LatLng(lat, lon), 
icon:'http://www.google.com/mapfiles/dd-start.png', 
map: map }); 

var end = new google.maps.Marker({ 
position: new google.maps.LatLng(lat1, long1), 
icon:'http://www.google.com/mapfiles/dd-end.png', 
map: map }); 
var request = { 
      origin: start, 
       destination: end, 
       optimizeWaypoints: true, 
      travelMode: google.maps.DirectionsTravelMode.DRIVING 
      };

是否清楚现在？我改变了我的问题。我想更改默认图标（带有字母的标记）。我想在源代码和目标位置用'http://www.google.com/mapfiles/dd-start.png'更改此图标我想将此图片http://www.google.com/ mapfiles/dd-end.png – mobileDeveloper 2012-04-02 15:41:43

Aha，你的意思是代替使用默认图标，你想使用自定义图标。 – 2012-04-02 15:45:18

是的，我想在搜索路线时使用自定义标记图标 – mobileDeveloper 2012-04-02 15:46:24

当您创建渲染器添加此选项，然后将您的标记在原点（开始）和目标（完）

directionsDisplay = new google.maps.DirectionsRenderer({ 
     suppressMarkers: true 
    });

这里是工作示例，根据您的要求进行更改。

这个例子不是我所需要的。当我点击按钮“get Direction”时，我想更改默认图标的图像。我得到相同的图标，路径中标记的默认图标 – mobileDeveloper 2012-04-04 14:39:23

好吧，我试试：

集visible = false和draggable = true在DirectionsRendererOptions对象
创建DirectionsRenderer对象
创建您自己的标记（与draggable=true选项）

通dragstart和drag事件从你的马rker向渲染标记（开始和结束）

google.maps.event.addListener(marker_start, 'dragstart', function(e) { 
    directionsRenderer.b.markers[0].setPosition(this.getPosition()); 
    google.maps.event.trigger(directionsRenderer.b.markers[0], 'dragstart', e); 
}); 

google.maps.event.addListener(marker_start, 'drag', function(e) { 
    directionsRenderer.b.markers[0].setPosition(this.getPosition()); 
    google.maps.event.trigger(directionsRenderer.b.markers[0], 'drag', e); 
}); 

google.maps.event.addListener(marker_end, 'dragstart', function(e) { 
    var l = directionsRenderer.b.markers.length - 1; 
    directionsRenderer.b.markers[l].setPosition(this.getPosition()); 
    google.maps.event.trigger(directionsRenderer.b.markers[l], 'dragstart', e); 
}); 

google.maps.event.addListener(marker_end, 'drag', function(e) { 
    var l = directionsRenderer.b.markers.length - 1; 
    directionsRenderer.b.markers[l].setPosition(this.getPosition()); 
    google.maps.event.trigger(directionsRenderer.b.markers[l], 'drag', e); 
});
