<%@ Page Language="C#" MasterPageFile="~/Site1.Master" AutoEventWireup="true"  CodeBehind="WebForm1.aspx.cs"
Inherits="WebApplication1.WebForm1" Title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
    <script src="js/jquery-1.7.2.js" type="text/javascript"></script>
    <script language="javascript" type="text/javascript">
        window.onfocus = function() {
            $('#msg').html($('#msg').html() + '<br/> focus');
        };
        window.onblur = function() {
            $('#msg').html($('#msg').html() + '<br/> Blur');
        };
    </script>
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">   
    <div id="msg">
    </div>
</asp:Content>

Answer 1

最后它解决了。谢谢你的帮助！

$(window).bind("load", function() {
        pageLoad();
    });

    var activeElement;

    function pageLoad() {
        activeElement = document.activeElement;
        document.onfocusout = logWindow;
    }

    function logWindow() {
        if (activeElement != document.activeElement) {
            activeElement = document.activeElement;
        }
        else {
            $('#msg').html($('#msg').html()+'<br/> Focus');
        }

    }

Answer 2

 window.onblur = function() { 
      $('#msg').html($('#msg').html() + '<br/> Blur');     
      return false;
 };

可能是事件正在冒泡。

window.onblur事件在使用IE8时也会触发window.onfocus事件
