alert("[testglobal]"); -> prints the name of the global: [testglobal]
alert([testglobal]); -> gives javascript error: testglobal is undefined

Several methods:

  1. PHP code

<script>
var whatever = "<?php= $phpVar ?>";
</script>
  1. URL

<?php
$r = $_GET['Result'];
?>
  1. use cookies to communicate

how would you do the opposite of that, like return a javascript variable into a php variable?

In reading on this, there are several ways.

Have the script reload the page:


<SCRIPT LANGUAGE="JavaScript" type="text/javascript">
<!-- //
document.write('<a href="another_page.php?name=Dave&number=100">another page</a>');
// -->
</SCRIPT>

or


<SCRIPT LANGUAGE="JavaScript" type="text/javascript">
<!-- //
var name="Dave";
var number=100;
document.write('<a href="another_page.php?name='+name+'&number='+number+'">another page</a>');
// -->
</SCRIPT>

The other option would be to use AJAX. It allows communication without having to reload the page. I can post some examples after lunch if needed.

Re: can I use globals in javascript event?

thats alright, thanks for the help though. You got me thinking with your first post, and I was able to figure out the problem I was having. I now have the save button prompt the user, and save the record if they click ok. I tried reloading the page and adding something to the URL, but that didn’t work because it was getting rid of all the form data.
