I encountered this problem today. Simply using the replace function will not work. It will change the case of the original string. Find the relevant code on the Internet and back it up yourself.
Ordinary replacement function
Copy the code code as follows:
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))
regular expression
Copy the code code as follows:
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")
