error: [Errno 10053] An established connection was aborted by the software in your host machine

　上面的异常总是在我刷新页面或者重新select serverType的时候出现，这样意味着可能刚才在排队执行的ajax请求在没有接收数据之前抛弃了链接，也就是“ajax发了请求，但是转开了，不再接收数据了。。。。” 然后在客户端就弹出了一个没有任何提示信息的弹出框。。。。



/article/4331975.html 这篇文章《windows错误代码解析》 里提到10053错误：

WSAECONNABORTED (10053) Software caused connection abort.

一个已建立的连接被你的主机上的软件终止，可能是因为一次数据传输超时或是协议错误。

　　每次页面刷新，然后就传输数据超时？或者说页面停留太久，请求太过于频繁？就abort connect了？

问题：页面上频繁的setTimeout定时请求，然后每次页面在切换走的时候，那些个setTimeout留下的残余ID，没有被清除掉。

解决方案： 为window绑定beforeunload事件，清除所有残留的setTimeout的ID。
