1. ASP中如何过滤指字文字前或指定文字后所有内容呢
可以用正则进行替换,例如以下代码可以替换a及以后的内所有容字符
<%
str="1234agds34.32"
Dim regEx
Set regEx=new RegExp
regEx.pattern="a.*"
regEx.IgnoreCase =false
regEx.Global=True
str=regEx.Replace(str,"00000")
Response.Write "aaa="&str
%>
2. ASP如何过滤数组内重复内容
dim a(4)
a(0)=1
a(1)=1
a(2)=2
a(3)=2
a(4)=3
for n=0 to ubound(a)-1
for s=1 to ubound(a)
if a(s)=a(n) then
a(n)=""
end if
next
next
a_new=filter(a,"")‘把a数组里面是空值的全部删掉,然后重新组合成一个a_new数组。
for n=0 to ubound(a_new)’打印出a_new数组。
response.write a_new(n)&"<br>"
next
说明:a_new是新生成的数组,去掉了a数组里面被清空的那些,重新生成了一个开头角标是0的a_new数组。
3. asp中如何过滤掉特殊字符
user=replace(trim(request.form("uName")),"'","''")
password=replace(trim(request.form("Password")),"'","''")
if instr(user,"%") or instr(user,"#") or instr(user,"?") or instr(user,"|") or instr(user,"'") then
response.write "<script language=javascript>alert('您的姓名含有非法字符!');this.location.href='login.asp';</script>"
response.end
end if
if instr(password,"%") or instr(password,"#") or instr(password,"?") or instr(password,"|") then
response.write "<script language=javascript>alert('您的密码含有非法字符!');this.location.href='login.asp';</script>"
response.end
end if 我自己做的,希望对你有帮助
