ToScript Output. CF >JS

I'm having some trouble passing a variable from Coldfusion to Javascript.

There are two defined session varaibles which work fine with the ToScript but fail when I try and use them inside the javascript.

<cfset session.ga_usersecret = "testGAUS" />

<cfset session.AIsession = "testGAS" />

<script type="text/javascript">

<cfoutput>

var #toScript(session.ga_usersecret, "GAuser")#

var #toScript(session.AIsession, "GAsession")#

var _gaq = _gaq || [];

_gaq.push(['_setAccount', 'UA-XXXXXX']);

_gaq.push(['_trackPageview']);

_gaq.push(['_setCustomVar', 1,'ID','GAuser',1]);

_gaq.push(['_setCustomVar', 2,'Segment','GAsession',2]);

</cfoutput>

</script>

Viewing the page source shows that the toScript works fine but it's not recognising the varaibles later in the script. Any ideas how to get the JS to output the varibale values?

Thanks in advance.

What's the idea of 'pushing' whole arrays? I expected you to be pushing one element at a time into an array, like this

var _gaq = ['_setAccount', 'UA-xxxxxx']; // initial array

// subsequent elements pushed into array

_gaq.push('_trackPageview');

_gaq.push(GAuser);

_gaq.push(GAsession);

Putting quotes around the name of a variable often produces unexpected results. 

To troubleshoot this, the first thing I would do is output the js variables into an alert right after I create them.

I've stripped the quotes out in the JS and am now running an alert directly after the toScript commands.

New Code:

<cfset session.ga_usersecret = "testGAUS" />

<cfset session.AIsession = "testGAS" />

<script type="text/javascript">

<cfoutput>

var #toScript(session.ga_usersecret, "GAuser")#;

var #toScript(session.AIsession, "GAsession")#;

alert('GAuser ' + GAuser + ' AND GAsession ' + GAsession);

var _gaq = _gaq || [];

_gaq.push(['_setAccount', 'UA-xxxxxx']);

_gaq.push(['_trackPageview']);

_gaq.push(['_setCustomVar', 1,'ID', GAuser,1]);

_gaq.push(['_setCustomVar', 2,'Segment', GAsession,2]);

</cfoutput>

</script>

The alert displays the variables correctly but they are still not being called into the _gaq.push.

Right, ignore all the ColdFusion stuff - is the JS in the page source valid? If you just put it in a static page and run it, does it work?

It looks like you're not using the variables in your push functions; you're

sending strings. Try this, maybe:

_gaq.push();

_gaq.push();
