Answer 1

從這裏http://bytes.com/topic/javascript/insights/825556-using-onbeforeunload-javascript-event

<script type="text/javascript"> 
    window.onbeforeunload = function(){ return 'Your Returned String Goes Here';} 
</script> 

Answer 2

我認爲onbeforeunload事件處理程序將是你在找什麼。

嘗試以下操作：

window.onbeforeunload = confirmExit; 
    function confirmExit() 
    { 
    return "You have attempted to leave this page. If you have made any changes to the fields without clicking the Save button, your changes will be lost. Are you sure you want to exit this page?"; 
    } 

Answer 3

看看卸載這個page的底部。
