关于文章分页
加入一篇几万字的文章，想让他自动分页,Pagesize自己制定
我的文章内容比如是:asoidhsadhasjkdhasjkdas
d
asd
asasdasdasdas
d
asd
sadopgjdfgjdklfgsdasdasda
dfsghasdsadsadasdasda
fhkgfhjklghsdasdasdas
gfh
gf
hfgdasdasdas
hg
fhgfklhkfldasdasdasdasdas
....
我想让他这样
asoidhsadhasjkdhasjkdas
d
asd
asasdasdasdas
d
asd
sadopgjdfgjdklfgsdasdasda
dfsghasdsadsadasdasda
[1] [2] [...]
第二页是
fhkgfhjklghsdasdasdas
gfh
gf
hfgdasdasdas
hg
fhgfklhkfldasdasdasdasdas
....
第[..]页是
....
怎么做到呢？刚刚看了好多材料，不是很明白
请大哥们说说自己的做法吧，小弟这里谢过了^o^
[解决办法]
自己学个方法.至于怎么写,我还在进行中.写好了拿来一起研究研究!
[解决办法]
通过JS控制吧，写个函数输出，如果字节数到了 或超过多少有换行符时 就分一页，其他隐藏！
[解决办法]
好象很难实行精确的分页.
只能通过加入分页码来进行分页吧,如需要分页的时候,插入一特别的字符串<Pager>!
[解决办法]
文章的分页我的方法是加标签,就是在要分页的地方加上分页标签
给个例子你把[code=C#][/code]using System;

长文章分页用首页下页上页未页足够了!没必要弄那么烦!最多再加一个跳转!可是文章分页用的着吗?
[解决办法]
按照字数或者行数把文章划分成几个大的片段，那就可以了。不过最好还是人手划分，否则导致上下文关联紧密的比分被自动划分开了，阅读起来就很不好。

抢个位~

.net里不是有一个分页的吗?
安装一下,分页的效果可以达到跟Google的分页式的,
什么都有,
好像是在PetShop里吧,记得不太清楚了~
[解决办法]
这是我写的分页.大家研究研究
/// <summary>
/// 取出内容
/// </summary>
/// <returns></returns>
public string content()
{
string title = "<div align='center'>";
pagesize=1000;
try
{
//替换掉空格
str = ds.Tables[0].Rows[0]["news_content"].ToString().Replace("?"," ");
strl = str.Length;
int ct = 1;
string b = Request.QueryString["page"];
if (b != null)
{
ct = Int32.Parse(Request.QueryString["page"]);
}
if(strl==(strl/pagesize)*pagesize)//看看页面的总记录是否能被每页的记录数整除
{
for(int i=1;i<=strl/pagesize;i++)
{
title += "<a href=CattleLook.aspx?titleid=" + getNum() + "&page="+i +">"+(i)+"</"+"a>页 ";
}
string s=str.Substring(pagesize*ct-pagesize,pagesize);
Response.Write(s);
}
else if(ct*pagesize>strl)//在不被整除的情况下,最后一页的设置,如字符长13,每页3,则处理最后那一页的显示
{
for(int i=1;i<=(strl/pagesize)+1;i++)
{
title += "<a href=CattleLook.aspx?titleid=" + getNum() + "&page=" + i + ">" + (i) + "</" + "a>页 ";
}
string s=str.Substring((ct-1)*pagesize,strl-(ct-1)*pagesize);
Response.Write(s);
}
else //在不被整除的情况下其他页面的显示设置
{
for(int i=1;i<=strl/pagesize+1;i++)
{
title += "<a href=CattleLook.aspx?titleid=" + getNum() + "&page=" + i + ">" + (i) + "</" + "a>页 ";
}
string s=str.Substring(pagesize*ct-pagesize,pagesize);
Response.Write(s);
}
title += "</div>";
}
catch{}
return title;
}
[解决办法]
或者如楼上所说 插入分隔符 然后灵活组织字符串的Split/SubString/IndexOf和string.Join()函数实现
或者类似于数据库分页 其实分隔字符也不是必须的
