javascript - 谷歌地图 API 3/javascript : Markers suddenly become invisible

Question

我创建了一个带有自定义标记的谷歌地图。

该项目已上线 10 个月。一切都工作正常，突然所有自定义标记都变得不可见。

之前， map 是这样的:

我最近没有更改代码。我已经恢复了备份，但问题仍然存在。

你能帮我了解发生了什么吗？

Click here to see the google map project online.

要使用 map ，只需单击 map 底部的链接 (Invisibles_décalcomanie xx)。这些链接将 map 移动到坐标。

我注意到了一些事情。如果用户缩小 map ，可以看到标记(见图)。但它们位于错误的位置，如果用户放大，它们就会消失。

这是一个错误吗？我的代码可能是错误的。或者 Google 最近对 API 进行了一些更改？

Javascript代码(可以在源代码底部的演示中看到):

    var markerArray = [];

    function initialize() {

Answer 1

您的 map 使用的是 Google Maps API v3 v3.10，the "released" version 。一旦成为“发布”版本，标记就出现了许多问题。作为测试，尝试将版本硬编码为 3.9。为此，请更改此行:

<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false"></script>

到

<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?v=3.9&sensor=false"></script>

如果有效，请提出 issue (或明星和现有的)，因为大约 6 个月后 v3.9 就会永久消失(当 3.10 变得“卡住”时)。

MarkerImage 类最近也已被弃用，取而代之的是 "Icon" object
