Article paging Methods

Source: Internet
Author: User

Method 1 of pagination function: pagination based on the number of words on each page

Public class articlepagebase
{
Public static httprequest request;
Public static string page;
Public articlepagebase ()
{

}

// The request here is submitted on the previous page

Public static string outputbysize (string p_strcontent, httprequest request, int ID) // paging Function
{
String m_strret = "";
Int m_intpagesize = 100; // size of each page of the document
Int m_intcurrentpage = 1; // set the first page to the initial Page.
Int m_inttotalpage = 0;
Int m_intarticlelength = p_strcontent.length; // Article Length
If (m_intpagesize <m_intarticlelength)
{// If the size of each page is greater than the length of the article, no paging is required.
If (m_intarticlelength % m_intpagesize = 0)
{// Set total pages count
M_inttotalpage = m_intarticlelength/m_intpagesize;
}
Else
{// If the totalsize
M_inttotalpage = m_intarticlelength/m_intpagesize + 1;
}
If (request. querystring ["Ps"]! = NULL)
{// Set current page number
Try
{// Handle abnormal Address Bar values
M_intcurrentpage = convert. toint32 (request. querystring ["Ps"]);
If (m_intcurrentpage> m_inttotalpage)

M_intcurrentpage = m_inttotalpage;

}
Catch
{
// M_intcurrentpage = m_intcurrentpage;
}
}
// Set the page content to get the size of the current page
If (m_intcurrentpage <m_inttotalpage)
{
M_intpagesize = m_intcurrentpage <m_inttotalpage? M_intpagesize: (m_intarticlelength-m_intpagesize * (m_intcurrentpage-1 ));
M_strret + = p_strcontent.substring (m_intpagesize * (m_intcurrentpage-1), m_intpagesize );
}
Else if (m_intcurrentpage = m_inttotalpage)
{
Int mm_intpagesize = m_intarticlelength-m_intpagesize * (m_intcurrentpage-1 );
M_strret + = p_strcontent.substring (m_intarticlelength-mm_intpagesize );
}

String m_strpageinfo = "";
For (INT I = 1; I <= m_inttotalpage; I ++)
{
If (I = m_intcurrentpage)
M_strpageinfo + = "[" + I + "]";
Else
M_strpageinfo + = "<a href =? PS = "+ I +"> ["+ I +"] </a> ";

}
If (m_intcurrentpage> 1)
M_strpageinfo = "<a href =? PS = "+ (m_intcurrentpage-1) +"> previous page </a> "+ m_strpageinfo;
If (m_intcurrentpage <m_inttotalpage)
M_strpageinfo + = "<a href =? PS = "+ (m_intcurrentpage + 1) +"> next page </a> ";
// Display the page numbers.
// This. showpagenumber. Text = "<p> </P>" + m_strpageinfo;
Page = "<p> </P>" + m_strpageinfo;

}
Else
{
M_strret + = p_strcontent;
}
Return m_strret;
}
}

 

Background call:

Protected void page_load (Object sender, eventargs E)
{

Int id = int. parse (request. querystring ["myid"]. tostring ());

Dataset DS = exambll. selectconetxtbyexaminationid (ID );

String STR = Ds. Tables [0]. Rows [0] ["context"]. tostring ();

Label1.text = articlepagebase. outputbysize (STR, request, ID );
Showpagenumber. Text = articlepagebase. page;

}

 

Front-end code:

<Div>
<Asp: Label id = "label1" runat = "server" text = "label"> </ASP: Label>
<Asp: Label id = "showpagenumber" font-size = "14px" runat = "server"> </ASP: Label>
</Div>

 

 

 

Pagination Based on separators:

# Region page start
Int page = 1; // The initial Page code. The first page is displayed.
String mypage = "1 ";
If (request. querystring ["page"]! = NULL)
{
Mypage = request. querystring ["page"];
}
If (mypage! = NULL) // when the page is not loaded for the first time, the result is null. Therefore, you need to determine
{
Page = convert. toint32 (mypage );
}

String content = Ds. Tables [0]. Rows [0] ["news_context"]. tostring ();
// The above content can be obtained from the database. For the convenience of demonstration, write the content directly. Use <p> to separate the content to be obtained.

String [] strcontent = NULL;

Strcontent = filesplit (content); // call the filesplit method to obtain the content in the array format

If (strcontent [page-1]! = NULL)
{

This. label1.text = strcontent [page-1]. tostring (); // display content
}
Else
{
This. label1.text = "NO content ";

}
String adpager = string. empty;

If (Int. parse (mypage)> 1)
{
Int qianpage = int. parse (mypage)-1;
Adpager + = "<a href = zixundetails. aspx? Id = "+ ID +" & page = "+ qianpage +"> previous page </a> ";
}

For (INT I = 0; I <strcontent. length; I ++)
{// Obtain the number of pages in the cyclic Array
Int npage = 0;
If (strcontent [I]! = NULL)
{
Npage = I + 1;
X = I + 1;
Adpager + = "<a href = zixundetails. aspx? Id = "+ ID +" & page = "+ npage +"> "+ npage +" </a> & nbsp ;";

}
}
If (Int. parse (mypage) <X) // strcontent. length)
{
Int xiapage = int. parse (mypage) + 1;

Adpager + = "<a href = zixundetails. aspx? Id = "+ ID +" & page = "+ xiapage +"> next page </a> ";

}
This. showpagenumber. Text = adpager. tostring (); // display the page

# Endregion end of page

 

 

Call method:

# Values separated by region
Public String [] filesplit (string contents)
{

Int fileindex = 0;
String [] splitfile = new string [10];
While (contents. length> 3000 & fileindex <9)
{

If (contents. indexof ("(* ^__ ^ *)", 3000) <0) break;

Splitfile [fileindex] = contents. substring (0, contents. indexof ("(* ^ __^ *)", 3000); // note that 10 is the number of words, and I use 10 for testing, you can set it based on your news page. I think it should be at least 200 words. Haha ......
Contents = contents. Remove (0, splitfile [fileindex]. Length );
Fileindex ++;
}
Splitfile [fileindex] = contents;
Return splitfile;
}
# Endregion
