字符串截取的几个function

function cutstr(thestr,strlen) dim l,t,c l=len(thestr) t=0 for dxy=1 to l c=Abs(asc(Mid(thestr,dxy,1))) if c>255 then t=t+2 else t=t+1 end if if t>=strlen then thev=left(thestr,dxy) exit for else bu=strlen-t for bui=1 to bu strbu=" " strbuall=strbuall&strbu next thev=thestr&strbuall strbu="" strbuall="" end if next cutstr=thev end function

Response.write(cutstr("fdsafdsafdsafdsafdasfdsa",10)&"<br>")
