需求说明

有时我们需要通过SQL标签调用栏目的介绍(classbasicinfo)及自定义内容(classdefinecontent),他们的结构是用这种方式存储的"a|||b|||c",这个时间，如果我们需要其中的一项，就需要split函数，而科汛没有提供，为此特意二次开发

代码修改：Kesion.Label.SQLCls.asp

示例：{$SQLReplace({$Field(ClassDefineContent,Text,0,0,2,)},||||,0)}

参说说明：参数1是为要拆分的内容，参数2是拆分的分割符，参数3是取第几位，注意是以0开始的

找到大约350行，增加以下红色部分

    End If
     KS_RS_Obj.MoveNext
   Next
  GetCirLabelContent=MySplitField(GetCirLabelContent)
  End Function

  Function MySplitField(lpFieldValue)
   Dim regEx, Matches, Match
   Dim FieldParam,FieldParamArr,mytempValue,mytempNum,mytarget,templpFieldValue
   Set regEx = New RegExp
   regEx.Pattern = "{\$SQLReplace\([^{\$}]*}"
   regEx.IgnoreCase = True
   regEx.Global = True
   Set Matches = regEx.Execute(lpFieldValue)  
   For Each Match In Matches
    FieldParam    = Replace(Replace(Match.Value,"{$SQLReplace(",""),")}","")
    FieldParamArr = Split(FieldParam,",")
    mytempValue=split(replace(Replace(KS.LoseHtml(KS.HtmlCode(FieldParamArr(0)))," ","")," ",""),trim(FieldParamArr(1)))
 if ubound(mytempValue)>=cint(FieldParamArr(2)) then lpFieldValue=Replace(lpFieldValue,Match.Value,mytempValue(FieldParamArr(2)))
   Next
     MySplitField=lpFieldValue
  End Function

调用说明：

SQL语句：select top {$Param(0)} classid,id,foldername,ClassDefineContent from ks_class where tn='{$Param(1)}' and topflag=1 order by folderorder asc

循环部分：<dl>[loop={$Param(0)}]<dt>{$SQLReplace({$Field(ClassDefineContent,Text,0,0,2,)},||||,0)}【<a href="{$Field(id,GetInfoUrl,100,1)}">{$Field(foldername,Text,0,...,0,)}</a>】</dt><dd>{SQL_疾病导航内部(10,{$Field(id,GetInfoUrl,100,2)})}</dd>[/loop]</dl>
