Question

由于MarkerImage消失了，我不断更新Marker的Icon。

对Marker.setIcon（{url：“icon url”，anchor：....}）的拳头调用正常，但是当我尝试在具有相同Object文字的同一标记上创建setIcon时，它会抛出此异常在调试器中：

<exception>: Af
message: "not a string"

stack: "Error↵ at Error (native)↵ at new Af (http://maps.googleapis.com/maps-api-v3/api/js/21/10/intl/de_ALL/main.js:26:682)↵ at Bf (http://maps.googleapis.com/maps-api-v3/api/js/21/10/intl/de_ALL/main.js:26:795)↵ at http://maps.googleapis.com/maps-api-v3/api/js/21/10/intl/de_ALL/main.js:28:60↵ at http://maps.googleapis.com/maps-api-v3/api/js/21/10/intl/de_ALL/main.js:28:181↵ at http://maps.googleapis.com/maps-api-v3/api/js/21/10/intl/de_ALL/main.js:28:401↵ at Zh.setIcon (http://maps.googleapis.com/maps-api-v3/api/js/21/10/intl/de_ALL/main.js:31:1423)↵ at $setIcon_6 (0.js:59576:15)↵ at $update_10 (0.js:98065:3)↵ at $liveTimerFireEvent (0.js:113687:7)"

在例外情况中显而易见，我使用的是版本21/10 有人有类似问题吗？我很快就用一个字符串而不是一个Icon的对象来测试它，它就像这样......

因为人们在我甚至有机会说它不是简单的js之前就投票了我的问题......这里是未提取的例子......

而不是指定您的图标：

marker0.setIcon({ url :  "http://1.bp.blogspot.com/_GZzKwf6g1o8/S6xwK6CSghI/AAAAAAAAA98/_iA3r4Ehclk/s1600/marker-green.png" });

直接使用URL，而不是作为传递给setIcon的结构的属性。这对我有用而不会抛出错误：

marker0.setIcon("http://1.bp.blogspot.com/_GZzKwf6g1o8/S6xwK6CSghI/AAAAAAAAA98/_iA3r4Ehclk/s1600/marker-green.png");

使用Object literal更新标记上的图标
