javascript asp教程第十二课教程第十二课—session对象对象
Overview:
The Session Object is how you track a single user across many pages. It has four (4) properties, two (2) collections, one (1)
method, and two (2) events.
Get Started:
In this series of examples we will create a password system. We will use the Session Object to track whether or not a user is
authorized to view certain pages. Below are several scripts for lesson12. Look at them, play with, and then read the
explanations that come further down the page.
<%@LANGUAGE=”JavaScript”%>
<%
//No ASP Here, just a regular HTML Page
%>
<HTML>
To play along with our password page, put in a user name and a password.<BR>
<BR>The correct user name is <I>guest</I>.<BR>
And the correct password is also <I>guest</I>.<BR>
<FORM METHOD=”post” ACTION=”script12a.asp”>
User:<INPUT TYPE=”text” SIZE=”9″ NAME=”userName” VALUE=”guest”><BR>
Pass:<INPUT TYPE=”password” SIZE=”9″ NAME=”userPassword” VALUE=”guest”>
<BR>
<INPUT TYPE=”submit” value=”Login”>
</FORM>
</HTML>
Click Here to run script12.asp in a new window. Below is script12a.asp.
<%@LANGUAGE=”JavaScript”%>
<%
var userName=new String(Request.Form(“userName”))
var userPassword=new String(Request.Form(“userPassword”))
if (userName==”guest” && userPassword==”guest”)
{
Session(“Authorized”)=true
Response.Redirect(“script12b.asp”)
}
else
{
Session(“Authorized”)=false
