The Cookie|cookies|javascript| tutorial cookie is a small piece of information that the browser stores to help identify the user. Setting up and checking cookies in a form requires two files to complete. The first file is cookie1.html, and this file requires some mechanism (a button in the example below) to check if a cookie exists and then redirect it to the form page or the document download page. And the second file, the form page (cookie2.html), is also important because you're going to use a little bit of JavaScript to set up cookies, which is done before submitting the form. Here's a file:
First file (cookie1.html)
<HTML>
<HEAD>
<script language= "JavaScript" >
<!--
function Cookieredirect (Hascookieurl, Nocookieurl)
{
var currentcookie = Document.cookie;
if (Currentcookie.indexof ("Formcomplete=yes")!=-1) {
window.location = Hascookieurl;
} else {
window.location = Nocookieurl;
}
}
-->
</SCRIPT>
</HEAD>
<BODY>
<form name= "Docdownload" >
<input type= "button" value= "Download Document"
>
</FORM>
</BODY>
</HTML>
Second file (cookie2.html) <HTML>
<HEAD>
<script language= "JavaScript" >
<!--
function Sendform (objform)
{
Cookieexpires = "Saturday, 01-jan-03 00:00:00 GMT";
Document.cookie = "Formcomplete=yes; path=/";
Objform.submit ();
}
-->
</SCRIPT>
</HEAD>
<BODY>
<form action= "test.html" name= "info" >
<TABLE>
<TR>
<td>first name</td>
<td><input type= "TEXT" name= "FirstName" ></TD>
</TR>
<td>last name</td>
<td><input type= "TEXT" name= "LastName" ></TD>
</TR>
<TR>
<TD>Address</TD>
<td><input type= "TEXT" name= "Address" ></TD>
</TR>
<TR>
<TD>City</TD>
<td><input type= "TEXT" name= "City" ></TD>
</TR>
<TR>
<TD>State</TD>
<td><input type= "TEXT" name= "state" ></TD>
</TR>
<TR>
<TD>Zip</TD>
<td><input type= "TEXT" name= "Zip" ></TD>
</TR>
</TABLE>
<input type= "button" value= "Download Document"
>
</FORM>
</BODY>
</HTML>
Here are the doc.html files you need to use:
Doc.html
<HTML>
<BODY>
</BODY>
</HTML>
To test this feature, you can open the cookie1.html and click the hit button, and you will be taken to the form page. If you go back to the cookie1.html file and click on the button you will be directly connected to the document.
