普通的替换函数

复制代码 代码如下:

public function HighLight(S,F)

dim tL,tM,tR,k

tL=""

tM=""

tR=S

k=instr(1,tR,F,1)

do while k>0

tL=tL & left(tR,k-1)

tM=mid(tR,k,len(F))

tL=tL & "<span>" & tM & "</span>"

tR=right(tR,Len(tR)-len(F)-k+1)

k=instr(1,tR,F,1)

loop

HighLight=tL & tR

end function

tS="abcaBcabCaBCabcaBCa"

tF="bc"

response.Write(tS)

response.Write("<br/>")

response.Write(HighLight(tS,tF))

正则表达式

复制代码 代码如下:

Function HighLight(S,F)

Dim regEx

Set regEx = New RegExp

regEx.IgnoreCase = True

regEx.Global = True

regEx.Pattern = "(" & F & ")"

HighLight = regEx.Replace(S,"<span>$1</span>")

End Function

Response.write HighLight("abcaBcabCaBCabcaBCa","bc")
