I have a simple jacascript that randomizes the background of the top
frame of my webpage http://www.duke.edu/~efn. For some reason, my
Internet Explorer started blocking the background and displaying this
instead: http://www.duke.edu/~efn/pic.jpg. This problem didn''t used to
occur, and it doesn''t happen on Firefox. Is there some way I can alter
the script of the top frame http://www.duke.edu/~efn/top.html to
prevent this from happening? Thanks. -Emmett

我看到我的系统上的IE6和Firefox 1.0没有区别。
问题出在你的IE浏览器中设置，而不是你的剧本。

I see no difference between IE6 and Firefox 1.0 on my system.
The problem is somewhere in your IE settings, not your script.

下面是你的脚本，我对它的评论：
< script language =" javascript" >
使用：< script type =" text / javascript">
var bgNum = Math.round（Math。 random（）* 6）;
使用：var bgNum = Math.floor（Math.random（）* 6）;
< url：< a rel =nofollowhref =http://jibbering.com/faq/#FAQ4_22target =_ blank> http://jibbering.com/faq/#FAQ4_22 />
bgSel = new Array（7）;
bgSel [0] =" 1.jpg" ;;
bgSel [1] = " 2.jpg";
bgSel [2] =" 3.jpg";
bgSel [3] =" 4.jpg" ;;
bgSel [4] =" 5.jpg";
bgSel [5] =" 6.jpg" ;;
bgSel [6] = " 7.jpg";
使用：
var bgSel = [
" 1.jpg"，
" 2.jpg"，
" 3.jpg"，
" 4.jpg"，
5。 jpg"，
" 6.jpg"，
" 7.jpg"
];
var base = bgSel [bgNum];
注意：你真的不需要将它分配给另一个变量。
< / script>
< / head>
< script language =" javascript">
document.write（"< body background =''" + base +"''>"）;
< / script>
注意：这里你的标记无效，因为你有一个< script>标签
在< head>< / head>之外和< body>< / body>。如果Javascript被禁用，
该页面没有< body>标签。
相反，你应该使用：
< head>
< style type =" text / css">
body {background-image：url（default.jpg）; }
< / style>
< script type =" text / javascript">
var bg = [
" 1.jpg"，" 2.jpg"，" 3.jpg"，" 4.jpg"，
" 5.jpg"，" 6.jpg"，" 7.jpg"
];
document.write（
''< style type =" text / css">''，
''body {background-image：url（''，
bg [Math.floor（Math.random（）* bg.length）]，
''）;}''，
''< \ / style>''
） ;
< / script>
< / head>
< body>
现在你可以通过简单地添加更多元素来扩展图像数量（因为我们使用的是bg.length而不是固定数字）。
如果用户已禁用CSS或过度使用CSS，则他们没有（或他们选择
）背景图像。
如果他们已启用CSS但JavaScript d他们得到了默认的
背景图片（指定为default.jpg）。
如果他们启用了CSS并启用了JavaScript，他们会随机选择
of 1..7.jpg。
在任何情况下，他们都不会得到无效的标记或没有< body>的页面标签。
在IE 6.0.2800，Firefox 1.0PR，Netscape 4.78，Opera
6.05，Opera 7.54和Mozilla 1.7.3中测试和工作。

Below is your script, and my comments on it:
<script language="javascript">
Use: <script type="text/javascript">
var bgNum = Math.round(Math.random() * 6);
Use: var bgNum = Math.floor(Math.random() * 6);
<url: http://jibbering.com/faq/#FAQ4_22 />
bgSel = new Array(7);
bgSel[0] = "1.jpg";
bgSel[1] = "2.jpg";
bgSel[2] = "3.jpg";
bgSel[3] = "4.jpg";
bgSel[4] = "5.jpg";
bgSel[5] = "6.jpg";
bgSel[6] = "7.jpg";
Use:
var bgSel = [
"1.jpg",
"2.jpg",
"3.jpg",
"4.jpg",
"5.jpg",
"6.jpg",
"7.jpg"
];
var base = bgSel[bgNum];
Note: You don''t really need to assign this to another variable.
</script>
</head>
<script language="javascript">
document.write("<body background=''" + base + "''>");
</script>
Note: you''ve got invalid markup here, because you''ve got a <script> tag
outside of <head></head> and <body></body>. And if Javascript is disabled,
the page gets no <body> tag at all.
Instead, you should use:
<head>
<style type="text/css">
body { background-image: url(default.jpg); }
</style>
<script type="text/javascript">
var bg = [
"1.jpg", "2.jpg", "3.jpg", "4.jpg",
"5.jpg", "6.jpg", "7.jpg"
];
document.write(
''<style type="text/css">'',
''body { background-image: url('',
bg[Math.floor(Math.random() * bg.length)],
''); }'',
''<\/style>''
);
</script>
</head>
<body>
Now you can expand the number of images by simply adding more elements to
the array (because we''re using bg.length instead of a fixed number).
If the user has CSS disabled or over-ridden, they get no (or their choice
of) background-image.
If they have CSS enabled but JavaScript disabled they get the default
background-image (specified as default.jpg).
If they have CSS enabled and JavaScript enabled they get a random choice
of 1..7.jpg.
In no case do they get invalid markup or a page with no <body> tag.
Tested and working in IE 6.0.2800, Firefox 1.0PR, Netscape 4.78, Opera
6.05, Opera 7.54 and Mozilla 1.7.3.

哦，是的，Internet Explorer 6.0.2900（Windows XP Service Pack 2）将
阻止document.write（）如果你在本地加载网站就会发生。
但是从Web服务器加载它应该可以正常工作。

And oh yes, Internet Explorer 6.0.2900 (Windows XP Service Pack 2) will
prevent the document.write() from occurring if you load the site locally.
But loaded off a Web server it should work okay.
