Can anyone figure out why this script doesn't work? It works in this sample:
http://javascript.internet.com/forms/passing-values.html
but when I use the code on my own PC, I get the word 'undefined' for each value on the second page.

Here is the source code:

It works on the web when I clicked on the links so it is a problem with your source code. Why don't your paste the code here so we can see what is wrong?

This may be because you have local. That code uses the URL string to get its info. You'll either need to upload to your website to test it or access the file via IP address. There is no url string submitted when you submit a form locally. This can be verified by noting that after you hit submit, after the ...html in your address bar, there is no '?this=that&that=this' stuff.

Here's the first page called senddata.html:

<html>
<head>

<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
function getParams() {
var idx = document.URL.indexOf('?');
var params = new Array();
if (idx != -1) {
var pairs = document.URL.substring(idx+1, document.URL.length).split('&');
for (var i=0; i<pairs.length; i++) {
nameVal = pairs[i].split('=');
params[nameVal[0]] = nameVal[1];
}
}
return params;
}
params = getParams();
// End -->
</script>

</head>

<BODY>

<!-- Demonstration -->
<center>
<form type=get action="passing_values_source.html">
<table border=1>
<tr>
<td>First Name:</td>
<td><input type=text name=firstname size=10></td>
</tr>
<tr>
<td>Last Name:</td>
<td><input type=text name=lastname size=10></td>

<tr>
<td>Age:</td>
<td><input type=text name=age size=3></td>

<tr>
<td colspan=2><input type=submit value="Submit!">
