Can an array be a session variable?

Yes.

---file1.asp---
<%
'Creating and initializing the array
Dim MyArray()
Redim MyArray(2)
myArray(0) = "hello"
myArray(1) = "World"

'Store the array in the Session object.
Session("StoredArray") = myArray

Response.Redirect("file2.asp")
%>

---file2.asp---
<%
'Retrieve the array from the Session Object
LocalArray = Session("StoredArray")

Response.Write(LocalArray(0)&LocalArray(1))

Instead of putting your onload="initialize()" in the <form> put the function on the bottom of the page. There is no need to use a session variable.

Been there, done that. Doesn't work - *unless I did something wrong? nah. never happens*. Anyway, I get the same error "xxxx is null or not an object"

could you post some code?

**RadarBob** · Jul 12, 2002, 03:48 PM

Here's the code cut down to the essentials. Just so it's clear.. this code works. If, for example, I tie it to the onfocus="initialize(this.form)" of some textbox (just to arbitrarily pick a convenient object on the form); then click into that textbox then volia! the values are copied, as desired, from the parent page to this page.

The alert()s in the function are for debugging purposes.

NOTE: I get the same error when the function call is placed immedialy after </form> or immediately after </body> or immediately after </html>.

NOTE: I think it is interesting that the error I get is "newList is null or not an object". The error is not flagging "theform" - as if it's been created... As well it should have been. And if it has, why not "newList"?

Code:

<html>
<title>Add Database Keywords</title>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<script language=javascript1.2>
<!-- Begin

............. lots of javascript functions here ......................

function initialize(theform) {
   var e = theform.newList.options;
   var originalList = new String ();
   
   for (var i=0; i<window.opener.DBForm.fKeywords.length; i++) {
       originalList += i + "= " + window.opener.DBForm.fKeywords.options[i].text + "\r";
   }
   alert ("the original list = \r" + originalList);
   originalList = "";
   
   for (var i=0; i<e.length; i++) {
    originalList += i + "= " + e[i].text + "\r";
   }
   alert ("the initial target list = \r" + originalList);

   originalList = "";
   
   with (window.opener.DBForm.fKeywords) {
      for (var i = 0; i < length; i++) {
         e[i] = new Option(options[i].text, options[i].value);
      }
   }

   for (var i=0; i<theform.newList.length; i++) {
    originalList += i + "= " + e[i].text + "\r";
   }
   alert ("the target list = \r" + originalList);
}  // initialize()

// End -->
</script>
</head>

<body>
<form>
  <center>
  <table width="-1" border="5" height="350">	

    .... stuf in rows....
      
    .......... heres the object I'm working with ...............
        <select size="6" name="newList" width="300" multiple tabindex="7"
         onKeyPress="return findOption(this)">
           <option value="00">&lt;--empty--&gt;</option>
        </select>
        
  </table>
  </center>
</form>

</body>

</html>

......... and here's the call to the script to pre-fill the above <SELECT> object............

<script language="JavaScript" type="text/javascript">
<!--
initialize(this.form);
//-->
</script>

Works great! Three hoots for Owl!!

The above line is at the bottom of my document, between the </body> and </html> tags and of course not inside a function, which will cause it to execute automatically when the page is built on the client.

To recap, here's what I am now doing: Adding and deleting, from a child page, a list of words on the parent page. All without redrawing or refreshing the parent page..

Since the list (a <select> object) can be dynamically refreshed (vis-a-vis adding rows to a <table>) I don't have to refresh/redraw the page - which prevents the entire nasty cycle of:

validate an incomplete form - and "shortcircuiting" the required field validations so I can:
save to the database
fetch from the database
rebuild the page on the server
send page to client
re-display page

P.S. vis-a-vis (veez a vee) "as compared to and contrasted with"
