Post Javascript variables to hidden Php iFrame

How to send javascript variables to a hidden PHP iFrame? I need to be able to access the javascript variables using PHP on the iFrame.

My Javascript vars that I need posted are like

var dstdate = dstime + 1;
var finalTime = time / 10;

And they go to a iframe Webtime.php

Sample code welcome.

Thanks

@mityaJun 30.2009 — If you're sending your vars via a form, just set your form's target property to the name of the iframe.

Otherwise, just put the following in your JS:

[CODE]nameOfIframe.location.href = 'script.php?var1='+var1+'&var2='+var2; //etc[/CODE]

I guess I need an AJAX solution since I'm not using a submit button, and I'm not refreshing the page. I saw this AJAX code snip that posts form fields to a frame without refresshing the page.

[CODE]
var agevalue=document.getElementById("myform").agefield.value //get value to post from a form field
var poststr = "name=" + encodeURI(namevalue) + "&age=" + encodeURI(agevalue)
[/CODE]

How can I modify it to post a variable that's not in a form field.

Hope I explained what I'm trying to do clearly.

Thanks
