I have created an order form that users javascript to create a new html
document when the customers clicks the "print page" button.
Once the new document has been created it then prints the document and
closes it with the following code:
<body onload="window.print(); window.close();">
This works correctly (or at least the way I expect it to work under MS
Internet Explorer, but it cuases Netscape to "crash"
Does anyone have an explanation as to why?
Thank you in advance,
Stephen

我在Firefox 1.5中的测试似乎表明window.print是异步的
;也就是说，脚本不会等待对话框在继续之前关闭
的框。例如，如果你将onload
处理程序更改为以下内容：
< body onload =" window.print（）; alert（''foo''）;">
....然后Firefox将显示foo警报首先，然后是打印
对话框。
不幸的是，似乎window.print从未成为任何一部分
正式规范，因此询问同步或异步是否是正确行为是没有意义的。但是，它是非常明显的不管怎样，它不应该'能够使
浏览器崩溃。

My testing in Firefox 1.5 seems to indicate that window.print is
asynchronous; that is, the script does not wait for the dialog box to
be closed before continuing. For example, if you change your onload
handler to the following:
<body onload="window.print(); alert(''foo'');">
....then Firefox will show the "foo" alert first, and then the Print
dialog.
Unfortunately, it seems that window.print has never been part of any
formal specification, so it''s meaningless to ask whether being
synchronous or asynchronous is the "correct" behavior. However, it''s
pretty obvious that no matter what, it shouldn''t be able to crash the
browser.

谢谢你的解释。
所以有没有办法在文件打印后关闭文件，或者
我只能留下它有一个神器让客户关闭。
Stephen
Thanks for the explanations.
So is there a way of closing the document after it has been printed, or
can I only leave it there is an artifact for the customer to close.
