<script language="javascript">
<!--
function opCheckUnload(){
  if(g_blnCheckUnload){
    try{
      window.event.returnValue = "if close the window,the auto task will complete with document no update version";
    }catch(e){}
  }
}
-->
</script>

<body onbeforeunload="opCheckUnload();">
</body>

不过这种用法不支持firefox,因为firefox不支持window.event,所以本人改了一种方式，应用如下：
window.onbeforeunload = function() {
   if(g_blnCheckUnload){
     return("if close the window,the auto task will complete with document no update version!");
   }
}

这样几种浏览器都支持了，弹出对话框如下：


但这里有个问题，本来还没有解决的，我用的浏览器是中文版，但我做的系统是英文版，这个事件弹出来的窗口所显示的语言随浏览器，没有办法自己在javascript里设置。

Step 1:

Begin the installation from the Eclipse Help menu item.
Install screen

Step 2:

This screenshot show the screen as it initially comes up. In this case you will need to change the radio button to indicate that this is a new install.

Install screen 

Step 3:

This screen will vary depending on the features you have installed already. You want to click on the New Remote Site button. If you are behind a proxy and the Eclipse install mechanism does not work, then you can download a zipped version of the update site and then click the New Local Site button instead.

Install screen

Step 4:

This screen is showing the New Remote Site dialog, filled in with the correct information to install Subclipse

    Name: Subclipse
    URL:  http://subclipse.tigris.org/update_1.0.x

Install screen

Step 5:

When you first come back to this screen, the site you added will NOT be selected. Be sure to select it before clicking Next.

Install screen

Step 6:

This next screen shows all of the features that are available to install.

Install screen

Step 7:

Click the button to accept the license agreement.

Install screen

Step 8:

Confirm the install location

Install screen

Step 9:

There is an Eclipse preference to turn off this next dialog. I have never seen a signed feature. Not even Eclipse.org nor IBM sign their features.

Install screen

Step 10:

Just a screenshot of the in-process installation.

Install screen

Step 11:

Eclipse needs to be restarted after installing Subclipse.

Install screen

Step 12:

Finally, after restarting Eclipse, the first thing you will typically want to do is open the Subclipse Repository perspective where you can define your repositories. Be sure to also check the online help as well as the Subclipse preferences located under Team -> SVN.

Install screen

解决办法：在子窗口里调用父窗口的javascript方法里，在调用ajax之前用方法：window.setTimeout(callAjaxMethod(),0),设置一个延时，那么ajax就在firefox里正常执行，不会出现"No data received from server!"的错误了。
