添加。
i我试图避免显示HTML文件并且有向下滚动，
因为它似乎不能一直工作
任何指针都非常赞赏

我们......我需要创建一个类似tail的unix。功能在我的网站上。
问题：
文本显示在滚动区域，并在
末尾添加一个新行，整个文本向下滚动，以便用户可以看到最后一项
已添加。
是否有用户无法找到结束键的原因？
结束到底。
首页回到顶部。
键通常位于键盘的中间部分，位于
箭头。
如果您的应用程序不支持End和Home，您可能需要考虑
修复它。它比编码JS滚动更容易。 ;）

以下是基本的，它添加了新行顶部
而不是底部（这对大多数用户更有意义），
并显示固定数量的条目，因此底线为
修剪掉了。
如果你想把它添加到底部，那也可以通过
删除第一个元素然后添加新元素结束。
< script type =" text / javascript">
//如果需要更长的尾巴，请添加更多元素
var tail = new Array（10）;
函数tailIt（x，y）{
tail.unshift（x）;
tail .pop（）;
document.getElementById（y）.innerHTML = tail.join（''< br>''）;
}
< / script>
< form action ="">
< table border =" 1">< tr> < td>
< input type =" text"大小= QUOT; 30英寸; name =" inText">
< / td>< td>
< input type =" button" value =" Add to tail" onclick ="
tailIt（this.form.inText.value，''outputCell''）;">
< / td>< td id = QUOT; outputCell" style =" width：20em;">
< script type =" text / javascript">
document.write（tail.join（' '< br>''））;
< / script>
< / td>

i need to create a unix like "tail" function on my site.
the question:
the text is displayed in a scrolled area and a new line is added at the
end and the entire text is scrolled down so that user can see the last item
added.
i am trying to avoid displaying an HTML file and have to scroll it down,
since it does not seem to work all the time
any pointer is highly appreciated
In article <42********@usenet01.boi.hp.com>, me**********@hp.com enlightened
us with...i need to create a unix like "tail" function on my site.
the question:

end and the entire text is scrolled down so that user can see the last item
added.
Is there a reason the user can''t find the End key?
End goes to the bottom.
Home goes to the top.
The keys are usually sitting in the middle section of the keyboard, above the
arrows.
If your application doesn''t support End and Home, you may want to consider
fixing that. It''s easier than coding JS scrolling. ;)

The following is rudimentary, it adds new lines to the top
rather than the bottom (which makes more sense to most users),
and displays a fixed number of entries so the bottom lines are
trimmed off.
If you want it to add to the bottom, that is possible too by
deleting the first element then adding the new one to the end.
<script type="text/javascript">
// Add more elements if a longer tail is required
var tail = new Array(10);
function tailIt(x,y){
tail.unshift(x);
tail.pop();
document.getElementById(y).innerHTML = tail.join(''<br>'');
}
</script>
<form action="">
<table border="1"><tr><td>
<input type="text" size="30" name="inText">
</td><td>
<input type="button" value="Add to tail" onclick="
tailIt(this.form.inText.value,''outputCell'');">
</td><td id="outputCell" style="width: 20em;">
<script type="text/javascript">
document.write(tail.join(''<br>''));
</script>
</td>
</tr>
</table>
</form>
