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

　上面的異常總是在我刷新頁面或者重新select serverType的時候出現，這樣意味着可能剛才在排隊執行的ajax請求在沒有接收數據之前拋棄了鏈接，也就是“ajax發了請求，但是轉開了，不再接收數據了。。。。”  然后在客戶端就彈出了一個沒有任何提示信息的彈出框。。。。

 

http://dadekey.blog.51cto.com/107327/23605  這篇文章《windows錯誤代碼解析》 里提到10053錯誤：

WSAECONNABORTED (10053) Software caused connection abort.

一個已建立的連接被你的主機上的軟件終止，可能是因為一次數據傳輸超時或是協議錯誤。

　　每次頁面刷新，然后就傳輸數據超時？或者說頁面停留太久，請求太過於頻繁？就abort connect了？

 

問題：頁面上頻繁的setTimeout定時請求，然后每次頁面在切換走的時候，那些個setTimeout留下的殘余ID，沒有被清除掉。

解決方案： 為window綁定beforeunload事件，清除所有殘留的setTimeout的ID。
