谷歌地图Javascript V3.8中引入的内存泄露（在IE 9中观察）

我有工作示例代码，包括显示IE 9泄漏（几Gb在几分钟内）。当您将V3.8更改为V3.7时，此内存泄漏不会发生！所以我的猜测是它在v3.8中推出！该代码似乎在Chrome/Firefox中工作，但我正在研究C＃Winform应用程序并使用嵌入式.NET webcontrol（一种围绕IE的COM包装器）。已经尝试过gecko .NET组件，但那对我来说是不可替代的。谷歌地图Javascript V3.8中引入的内存泄露（在IE 9中观察）

我在这里和绝望的坚持，所以如果有人会这么好心提供一个解决方案...

日Thnx 罗布

无作用域（和全局范围）变量知道引起内存泄漏。我建议你确保所有变量的范围都是正确的。

Thnx为您的答案。我做了更多的研究，并得出结论它与V3.8相关！ –
