I am attempting the simple task of passing a value entered in a form field to the next page so it can be dsplayed in a simple hello message.

THE CODE I HAVE TO CAPTURE THE FORM VARIBALE AND SETUP THE ADDRESS OF THE SECOND PAGE IS:

<head>
<script language="Javascript">
function selectWindow() {
var address
address = "HTMLKITOUTPUT.HTM?searchfor=" +
document.searchcust.searchfor.value
window.open(address,"","HEIGHT=800,WIDTH=1000&quot

}
</script>
</head>
<body>
Customer Selection
<form name="searchcust" >
<p>Search For <input type="text" NAME="searchfor" value=""
onchange="selectWindow()">
<p>
</form>
</body>

THE SECOND PAGE TO DISPLAY THE MESSAGE IS:

<head>
<meta http-equiv="content-type"
content="text/html;charset=iso-8859-1">
<title>Searching For </title>
<script language="JavaScript">
function showsearch() {
var alertmsg
alertmsg = "We are searching for($searchfor)"
alert(alertmsg)
}
</script>
</head>

<body onLoad="showsearch()" >

<script language="JavaScript" type="text/JavaScript">
var request = new Object();
myname = request.searchfor
</script>

Hello <script language="JavaScript" type="text/JavaScript">document.write(myname)</script>

The second page displays but the result I am getting is that the variable is undefined .

Any ideas AND THANKS !!!

searchfor is not defined as a variable. You have only used seachfor.value to populate part of the variable address. Define searchfor as a variable first then call it. DeZiner

Can you spoon feed me by inserting where the declaration goes as I have been tooling around for an hour without success.

try...

**
searchfor = document.searchcust.searchfor.value

address = "HTMLKITOUTPUT.HTM?searchfor=" + searchfor
**

I am now getting it to the point where I have the output page opening with the address line of:
file:///D:/My%20Documents/My%20Webs/myweb/HTMLKITOUTPUT.htm?searchfor=helen
Assuming "Helen" was the string entered.

At this point I am stuck retreiving and displaying the string on the output page. In the showsearch function, the alert message is dipslaying as "We are searching for ($searchfor)

As I understand the problem, you already have a correct url with parameter passed using "?", and now you need to extract the value passed.
So here it is:

function searchIt() {
value = document.location.search;
value = value.substring(11, value.length);
alert(value);
}

You may call the searchIt() function like this:
<a href="javascript:searchIt()">search</a>
or any other way.

It was tested and works fine.
[tt]value.substring(11, value.length)[/tt] extracts all chars from ?searchfor=something, starting from 12th because the length of "?searchfor=" equals 11 chars. So alert box will show you "something".

Hope this will solve the problem.

It worked..thanks Starway.

In the statement :
value = document.location.search;

I assume these are reserved words that will create the value based on :

Document. = the document currently loaded
Location. = the URL of the document
search = whatever is after the ?
