dim name,pwd,email,person
dim sql
dim rs
if request("txt1")="" then
response.write "<script language=JavaScript>" & chr(13) & "alert('请输入用户名！');" & "history.back()" & "</script>"
end if
if request("txt2")="" then
response.write "<script language=JavaScript>" & chr(13) & "alert('密码不充许为空！');" & "history.back()" & "</script>"
end if
if request("txt2")<>request("txt3") then
response.write "<script language=JavaScript>" & chr(13) & "alert('两次输入的密码不一致！');" & "history.back()" & "</script>"
end if
name=request("txt1")
password=request("txt2")
email=request("txt4")
sex=request("sel1")

sex=request("sel1")
sql="select * from user where username='"&name&"'"
set rs=server.createobject("adodb.recordset")
set rs1=server.createobject("adodb.recordset")'不懂rs1的作用
rs.Open sql,conn,1,1
if rs.EOF then //rs查询下数据库看看现在user表里面有没有和现在的用户名相同的，没有的话 就执行下面
sql="insert into user(username,password,email,sex) values('"&name&"','"&password&"','"&email&"','"&sex&"')"
rs1.Open sql,conn,1,1 //rs1的作用就是执行上面的sql插入用户数据
set rs1=server.createobject("adodb.recordset")'不懂rs1的作用
sql="insert into user(username,password,email,sex) values('"&name&"','"&password&"','"&email&"','"&sex&"')"
rs1.Open sql,conn,1,1
