Question

我使用此代码在经典的asp + Mysql中显示记录集的分页：

<ul class="pagination">
    <% IF Cint(PageNo) > 1 then %>
    <li><a rel="1" href="#" data-topic="<%=Request.QueryString("TOPIC_ID")%>" data-page="1">Prime</a></li>
    <li><a rel="<%=PageNo-1%>" href="#" data-topic="<%=Request.QueryString("TOPIC_ID")%>" data-page="<%=PageNo-1%>"><</a></li>
    <% End IF%>
    <% For intID=1 To TotalPage%>
    <% if intID=Cint(PageNo) Then%>
    <li><a href="" class="selected"><%=intID%></a></li>
    <%Else%>
    <li><a rel="<%=intID%>" href="#" data-topic="<%=Request.QueryString("TOPIC_ID")%>" data-page="<%=intID%>"><%=intID%></a></li>
    <%End IF%>
    <%Next%>
    <% IF Cint(PageNo) < TotalPage Then %>
    <li><a rel="<%=PageNo+1%>" href="#" data-topic="<%=Request.QueryString("TOPIC_ID")%>" data-page="<%=PageNo+1%>">></a></li>
    <li><a rel="<%=TotalPage%>" href="#" data-topic="<%=Request.QueryString("TOPIC_ID")%>" data-page="<%=TotalPage%>">Ultime</a></li>
    <% End IF%>
  </ul>

但是，如果我有很多页面结果，它会显示一长串的数字....如何在更改页面时只显示5页，显示下一个？

像这样：

首先＆lt; 1 2 3 4 5>最后

如果我点击5

首先＆lt; 5 6 7 8 9>最后

等...

我在ASP中需要一个类似的解决方案。我找不到任何有用的东西，所以我自己做了一些东西。

我通常只用PHP编程，但在我做这个的情况下这是不可能的。因此，如果我的代码有点slopy，请随时改进;）

我做的一个小功能：

<%

page = cInt(Request.QueryString("pg"))
pages = cInt(number of pages)

if page <1 then page = 1
if page > pages then page = pages

Function paginationHTML(page, lastPage, URL)

if page >1 then
    paginationHTML = "<a href=""" & URL & page-1 & """>prev</a>"
    paginationHTML = paginationHTML & "<a href=""" & URL & "1"">1</a>"
end if

if page >2 then
    paginationHTML = paginationHTML & "<a>...</a>"
end if

if page >0 then
    paginationHTML = paginationHTML & "<a href=""" & URL & page & """ class='jp-current'>"& page &"</a>"
end if

if lastPage >2 then
    if page < lastPage-1 then
        paginationHTML = paginationHTML & "<a>...</a>"
    end if
end if

if page < lastPage then
    paginationHTML = paginationHTML & "<a href=""" & URL & lastPage & """>"&lastPage&"</a>"
    paginationHTML = paginationHTML & "<a href=""" & URL & page+1 & """>next</a>"
end if


End Function

%>

像这样使用：

<%=paginationHTML(page,pages,"?pg=")%>

如果您想保留其他一些查询字符串参数，此代码也可以使用。它删除页面值，添加新页面值并构建分页控件html。

它使用Twitter Bootstrap样式：http://twitter.github.io/bootstrap/components.html#pagination

用法：

Response.Write PagingControl(10, 30, "?field-keywords=whatever&page=7")

代码：

    Public Function RemoveEmptyQueryStringParameters(strQueryString)
        If IsNullOrEmpty(strQueryString) Then Exit Function

        Dim strNewQueryString: strNewQueryString = ""
        strQueryString = Replace(strQueryString, "&amp;", "&")
        strQueryString = Replace(strQueryString, "?", "&")

        Dim arrQueryString: arrQueryString = Split(strQueryString ,"&")

        For i=0 To UBound(arrQueryString)
            strTempParameter = Left( arrQueryString(i), Instr( arrQueryString(i) & "=", "=" ) - 1 )
            strTempParameterValue = Right( arrQueryString(i), Len( arrQueryString(i) ) - InstrRev( arrQueryString(i), "=" ) )
            If Not IsNullOrEmpty(strTempParameterValue) Then
               strNewQueryString = strNewQueryString & "&" & arrQueryString(i)
            End If
        Next

        If InStr(strNewQueryString,"&") = 1 Then
            strNewQueryString = "?" & Right(strNewQueryString, Len(strNewQueryString) - 1)
        End If
        strNewQueryString = Replace(strNewQueryString, "&", "&amp;")

        Erase arrQueryString
        Set arrQueryString = Nothing

        RemoveEmptyQueryStringParameters = Trim(strNewQueryString)
    End Function

    Public Function AddQueryStringParameter(ByVal strQueryString, ByVal strParameter, ByVal strValue)
        Dim strNewQueryString: strNewQueryString = ""
        strNewQueryString = Replace(strQueryString, "&amp;", "&")
        strNewQueryString = Replace(strNewQueryString, "?", "&")

        strNewQueryString = strNewQueryString & "&" & strParameter & "=" & strValue

        If InStr(strNewQueryString,"&") = 1 Then
            strNewQueryString = "?" & Right(strNewQueryString, Len(strNewQueryString) - 1)
        End If
        strNewQueryString = Replace(strNewQueryString, "&", "&amp;")

        AddQueryStringParameter = Trim(strNewQueryString)
    End Function

    Public Function PagingControl(ByVal intPage, ByVal intPageCount, ByVal strQueryString)
        If intPageCount <= 1 Then
            PagingControl = ""
            Exit Function
        End If

        strQueryString = RemoveEmptyQueryStringParameters(strQueryString)
        strQueryString = RemoveQueryStringParameter(strQueryString, "page")

        Dim strQueryStringPaging: strQueryStringPaging = ""
      Dim strHtml: strHtml = "<div class=""pagination""><ul>"

      If cInt(intPage) > 1 Then
             strQueryStringPaging = AddQueryStringParameter(strQueryString, "page", "1")
             strHtml = strHtml & "<li><a href=""" & strWebSiteUrl & strQueryStringPaging & """>Anfang</a></li>"

             strQueryStringPaging = AddQueryStringParameter(strQueryString, "page", CInt(intPage - 1))
         strHtml = strHtml & "<li><a href=""" & strWebSiteUrl & strQueryStringPaging & """>&lt; Zur&uuml;ck</a></li>"
      Else

      PagingControl = Trim(strHtml)
    End Function
