怎样运用日历功能查看指定日期的留言-动易Cms

来源:互联网 作者:佚名 时间:2013-04-17 11:29

在网站留言页面上增加了一个日历,如何实现点击相应时间,即可查到当日的留言?

下面是实现方法:

1、将以下代码保存为calendar.asp,放入到GuestBook目录下

<style>
    html,body{margin:5px 0px 0px 0px;height:100%;font-size:9pt}
    td { font-family: "宋体"; font-size:9pt}
</style>
<table width="180" cellpadding="0" cellspacing="1" bgcolor="dddddd" align=center>
<%
   '以下为ASP中通过该日历算法实现的具体代码
   '先判断是否指定了一个年份和月份,没有则根据当前的年和月份显示
    If Request("ReqDate")="" then
         CurrentDate=Date
    else
         CurrentDate=Trim(Request("ReqDate"))
    end if 
    pyear=year(CurrentDate)
    pmonth=month(CurrentDate)
 
    '以下的代码生成日历显示的表格头内容
%>
  <tr align="LEFT" bgcolor="#dddddd"> 
       <td width="14%" height="19" align="center">
           <input type="button" value="<<" onClick="JavaScript:location.href='?ReqDate=<%=DateAdd("m",-1,CurrentDate) %>'">
      </td>
     <td colspan="5" align="center">
        <%=pyear%>年<%=pmonth%>月
     </td>
     <td width="14%" align="center">
        <input type="button" value=">>" onClick="JavaScript:location.href='?ReqDate=<%=DateAdd("m",1,CurrentDate)%>'">
     </td>
  </tr>
  <tr align="center" bgcolor="#CCCCCC"> 
    <td width="14%" height="19"> 日</td>
    <td width="14%"> 一</td>
    <td width="14%"> 二</td>
    <td width="14%"> 三</td>
    <td width="14%"> 四</td>
    <td width="14%"> 五</td>
    <td width="14%"> 六</td>
  </tr>
  <tr align=center bgcolor=ffffff height=19>
  <%
  '由于ASP中没有获取指定月共有多少天的函数,因此我们需要通过其他算法来获得,算法其实很简单,就是计算一下要显示月份的1日至下个月的1日一共相差几天
    fromDate = FormatDateTime(month(CurrentDate) & "/1/" &  year(CurrentDate)) 
    toDate = FormatDateTime(DateAdd("m",1,fromDate)) 
    '获得要显示月份的第一天为周几
    nunmonthstart=weekday(fromDate)-1
    '获得要显示的1日至下个月的1日一共相差几天(月份一共有多少天)
    nunmonthend=DateDiff("d",fromDate,toDate)
    '判断显示日历需要用几行表格来显示(每行显示7天)
    if nunmonthstart+nunmonthend<36 then
         maxi=36
    else
         maxi=43
    end if
    '循环生成表格并显示
    i=1
    do while i<maxi
        iv=i-nunmonthstart
        if   i>nunmonthstart and i<=nunmonthend+nunmonthstart then
            '如果为显示的是今天则用红色背景显示
            if  iv=Day(now) and month(now)=pmonth and year(now)=pyear then
                response.write( "<td align=center bgcolor=ffaaaa><a href='Search.asp?Field=GuestTime&KindID=0&keyword=" &pyear& "-" & pmonth & "-" & iv & "' target=_parent>" & iv & "</a></td>")
            else
                response.write( "<td align=center><a href='Search.asp?Field=GuestTime&KindID=0&keyword=" &pyear& "-" & pmonth & "-" & iv & "' target=_parent>" & iv & "</a></td>")
            end if
        else
            response.write( "<td> </td>")
        end if
 
   '如果能被7整除(每行显示7个)则输出一个换行
        if i mod 7=0 then
            response.write( "</tr><tr align=center bgcolor=ffffff height=19>")
        end if
        i=i+1
    loop
%>
</table> 
 

2、修改PowerEasy.GuestBook.asp文件

找到

                If IsDate(Trim(Request("keyword"))) = False Then
                    FoundErr = True
                    ErrMsg = ErrMsg & "<li>" & XmlText("Guest", "ShowAllGuest/Err1", "输入的关键字不是有效日期!") & "</li>"
                    Exit Sub
                Else
                    If SystemDatabaseType = "SQL" Then
                        sqlGuest = sqlGuest & " and GuestDatetime = '" & Trim(Request("keyword")) & "' "
                      Else
                        sqlGuest = sqlGuest & " and GuestDatetime = #" & Trim(Request("keyword")) & "# "
                    End If
                End If
  -----------------------------------------------------------------------------------
 改为
                If IsDate(Trim(Request("keyword"))) = False Then
                    FoundErr = True
                    ErrMsg = ErrMsg & "<li>" & XmlText("Guest", "ShowAllGuest/Err1", "输入的关键字不是有效日期!") & "</li>"
                    Exit Sub
                Else
                    If SystemDatabaseType = "SQL" Then
   '如果数据量不大,用datediff是可以的,否则影响性能就最好用>=和 <  
              ' sqlGuest = sqlGuest & " and GuestDatetime = '" & Trim(Request("keyword")) & "' "
              'sqlGuest = sqlGuest & " and  GuestDatetime between '" & Trim(Request("keyword")) & " 00:00:00'  and '" & Trim(Request("keyword")) & " 23:59:59' "
              sqlGuest = sqlGuest & " and datediff(day,guestdatetime,'" & Trim(Request("keyword")) & "')=0 "
                    Else    
              'sqlGuest = sqlGuest & " and GuestDatetime = #" & Trim(Request("keyword")) & "# "
              sqlGuest = sqlGuest & " and GuestDatetime between #" & Trim(Request("keyword")) & " 00:00:00#  and  #" & Trim(Request("keyword")) & " 23:59:59#  "
              'sqlGuest = sqlGuest & " and datediff(day,guestdatetime,'" & Trim(Request("keyword")) & "')=0 "
                    End If
                End If

 


3、在相应留言模板页加入

     <iframe  src="calendar.asp" style="width:216px; height:210px;" scrolling="no" frameborder="0" allowTransparency="true"></iframe>
