选择列表值的ColdFusion URL变量

Question

I have a select list that I am populating via a call to a CFC

<select class="required" name="customer_checkout" id="customer_checkout" tabindex="0" onchange="PopulateGrandTotal();">
            <option>Please make a selection</option></select>

Once a user makes a selection I have them being directed to a payment gateway for a checkout process and the I am required to provide them with a call back URL for when the transaction is complete. I would like like to provided a URL variable in that callback URL of the value of the selection made from my selectlist, but I am unsure of how to do that.

I was thinking I could get the value on the fly via javascript by something like this:

var variable = encodeURIComponent($('#customer_checkout').val());

But I don't know how to get that into a URL variable.

My callback url looks something like this currently:

"https://www.myurl.com/pos/check_out.cfm?msg=1"

I would like to add another URL variable after the current msg variable.

If you are processing the redirect via javascript and you have the URL encoded value and you have the URL itself, you can do a simple concatenation via javascript like var newURL = "https://www.myurl.com/pos/check_out.cfm?msg=1&myvar=" + variable; If this doesn't answer the question, could you update your question with full sample code (ie gist, plunker, jsfiddle, etc)?
