class searchfile
dim folders 传入绝对路径,多路径使用+号连接,不能有空格
dim keyword 传入关键词
dim objfso 定义全局变量
dim counter 定义全局变量，搜索结果的数目
*****************初始化**************************************
private sub class_initialize
set objfso=server.createobject("scripting.filesystemobject")
counter=0 初始化计数器
end sub
************************************************************
private sub class_terminate
set objfso=nothing
end sub
**************公有成员,调用的方法***************************
function search
folders=split(folders,"+") 转化为数组
keyword=trim(keyword) 去掉前后空格
if keyword="" then
response.write("<font color=red>关键字不能为空</font><br/>")
exit function
end if
判断是否包含非法字符
flag=instr(keyword,"\") or instr(keyword,"/")
flag=flag or instr(keyword,":")
flag=flag or instr(keyword,"|")
flag=flag or instr(keyword,"&")
if flag then 关键字中不能包含\/:|&
response.write("<font color=red>关键字不能包含/\:|&</font><br/>")
exit function 如果包含有这个则退出
end if
多路径搜索
dim i
for i=0 to ubound(folders)
call getallfile(folders(i)) 调用循环递归函数
next
response.write("共搜索到<font color=red>"&counter&"</font>个结果")
end function
***************历遍文件和文件夹******************************
private function getallfile(folder)
dim objfd,objfs,objff
set objfd=objfso.getfolder(folder)
set objfs=objfd.subfolders
set objff=objfd.files
历遍子文件夹
dim strfdname 声明子文件夹名
*********历遍子文件夹******
on error resume next
for each onedir in objfs
strfdname=onedir.name
系统文件夹不在历遍之列
if strfdname<>"config.msi" eqv strfdname<>"recycled" eqv strfdname<>"recycler" eqv strfdname<>"system volume information" then
sfn=folder&"\"&strfdname 绝对路径
call getallfile(sfn) 调用递归
end if
next
dim strflname
**********历遍文件********
for each onefile in objff
strflname=onefile.name
desktop.ini和folder.htt不在列取范围
if strflname<>"desktop.ini" eqv strflname<>"folder.htt" then
fn=folder&"\"&strflname
counter=counter+coloron(fn)
end if
next
***************************
关闭各对象实例
set objfd=nothing
set objfs=nothing
set objff=nothing
end function
*********************生成匹配模式***********************************
private function createpattern(keyword)
createpattern=keyword
createpattern=replace(createpattern,".","\.")
createpattern=replace(createpattern,"+","\+")
createpattern=replace(createpattern,"(","\(")
createpattern=replace(createpattern,")","\)")
createpattern=replace(createpattern,"[","\[")
createpattern=replace(createpattern,"]","\]")
createpattern=replace(createpattern,"{","\{")
createpattern=replace(createpattern,"}","\}")
createpattern=replace(createpattern,"*","[^\\\/]*") *号匹配
createpattern=replace(createpattern,"?","[^\\\/]{1}") ?号匹配
createpattern="("&createpattern&")+" 整体匹配
end function
**************************搜索并使关键字上色*************************
private function coloron(filename)
dim objreg
set objreg=new regexp
objreg.pattern=createpattern(keyword)
objreg.ignorecase=true
objreg.global=true
retval=objreg.test(filename) 进行搜索测试,如果通过则上色并输出
if retval then
output=objreg.replace(filename,"<font color=#ff0000>$1</font>") 设置关键字的显示颜色
***************************该部分可以根据需要修改输出************************************
output="<a href=#>"&output&"</a><br/>"
response.write(output) 输出匹配的结果
*************************************可修改部分结束**************************************
coloron=1 加入计数器的数目
else
coloron=0
end if
set objreg=nothing
end function
