★★★★★如何在html中对一个文件分页显示信息?

52001314 2003-08-27 09:35:00

我想在html中显示一个a.txt中所有内容.但是,我的html页面大小是固定的,如果文件长度太长,要做成分页显示.
这样,我如果要更改html显示的信息,只要更改a.txt的内容就行了.
请问如何实现,最好能提供例子,谢谢.

读c:\\yourtxt.txt文件，路径可自行修改

<body id=mybody background="down.gif" onload=f_click()>

<SCRIPT language="JavaScript">
function f_click(){
objDownload.startDownload("c:\\yourtxt.txt", onDownloadDone);
}
current=0;
spacerows=3;//需要空多少行在这里设定
spacecols=6;//需要空多少列在这里设定
readrows=5;//每次读出的行数
spacestr="";
for(i=0;i<spacecols;i++)
spacestr+=" ";
function onDownloadDone(data){
mywrap=data.split("\n");
if(mywrap[0]!=null)
{
for(k=0;k<spacerows;k++)
paratext.innerHTML+="<br>";

for(j=0;(j<readrows)&&(mywrap[j]!=null);j++)
paratext.innerHTML+=spacestr+mywrap[j]+"<br>";
current=j;
}
}

function keyDown()
{
var key=window.event.keyCode;
if(key==40)
{
if(current<mywrap.length)
{
if(current>=mywrap.length-readrows)
mybody.style.backgroundImage='url(up.gif)';
paratext.innerHTML="";
for(k=0;k<spacerows;k++)
paratext.innerHTML+="<br>";

for(j=0;(j<readrows)&&(mywrap[j+current]!=null);j++)
paratext.innerHTML+=spacestr+mywrap[j+current]+"<br>";
current+=readrows;
}
}
else if(key==38)
{
/*if(mybgs.src!='')
mybgs.src='';
else
mybgs.src='sound.midi';
*/

if(current>=mywrap.length-readrows)
{
mybody.style.backgroundImage='url(down.gif)';
current-=readrows;
}
if(current<=0)
current=readrows;
paratext.innerHTML="";
for(k=0;k<spacerows;k++)
paratext.innerHTML+="<br>";

for(j=0;(j<readrows)&&(mywrap[j+current-readrows]!=null);j++)
paratext.innerHTML+=spacestr+mywrap[j+current-readrows]+"<br>";
if(current>readrows)
current-=readrows;
}
}
document.onkeydown=keyDown;
</SCRIPT>
<IE:Download ID="objDownload" STYLE="behavior:url(#default#download)" />
<div id=paratext></div>
</body>

读c:\\yourtxt.txt文件，路径可以自己定

<body id=mybody background="down.gif" onload=f_click()>

spacestr+=" ";
function onDownloadDone(data){
mywrap=data.split("\n");
if(mywrap[0]!=null)
{
for(k=0;k<spacerows;k++)
paratext.innerHTML+="<br>";

for(j=0;(j<readrows)&&(mywrap[j]!=null);j++)
paratext.innerHTML+=spacestr+mywrap[j]+"<br>";
current=j;
}
}
