簡單的js分頁尾本_javascript技巧

複製代碼 代碼如下:

<%@ Page Language="C#" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>無標題頁</title>
<script language="javascript" type="text/javascript" >
function showpage(url,num,c_p)
{
var prev=0;var next=0;var temp=0;var html="";
if(parseInt(c_p+3)>num)
{

}
else
{
prev=parseInt(c_p+3);
}
temp=10-(prev-c_p);
if(c_p-temp>0)
{
next=c_p-temp;
}
else
{
next=1;
}
//如果顯示的第一頁<10，總頁數又大於10
if(c_p+3<10&&num>c_p+3)
{
for(j=1;j<=10-(c_p+3);j++)
{

}
}
if(c_p!=num)
{
html+="<a href='"+url+"index="+(1+c_p)+"'>上一頁</a>"+" ";
}

{

}
else
{

}
