sending variable through ajax post?

Question

I'm doing some ajax stuff which triggers on a click event, the link has a couple of values and variables.

The link in question looks like this:

<?php $link_url = esc_url(wp_nonce_url( site_url('?my_page=ajax-processor&action=dynamic_date_loop&my_date='.$date), 
"dynamic_date_loop_nonce") ); ?>

The $date variable above holds a string like "2013-09".

I process this link and extract the values here:

var url = wpAjax.unserialize(element.attr('href'));
var s = {};
s.data = $.extend(s.data, { action: url.action, _ajax_nonce: url._wpnonce });

I understand the syntax for this goes something like var1:value1 but here my value is a variable, so in this context do I just add my_date: url.$date ? This just doesn't look right to me.

You won't have access to your PHP variable $date when you're executing your javascript code. You'll have to extract it from the query string you've assembled and placed in the javascript variable url. — user1864610

I think this is what you want:

s.data = $.extend(s.data, {
    action: url.action,
    _ajax_nonce: url._wpnonce,
    my_date: url.my_date 
});

Thanks for the reply, so does url.my_date know that I mean, get the value that is inside the php variable $date?

No, it's getting it from the my_date=XXX parameter in the URL, just like url.action gets the action=dynamic_date_loop parameter.

No you need to store the value in javascript variable

var a = '<?php echo $date; ?>';

Now variable a contains the value of $date. Now you can do whatever you want with a. Check it by alerting alert(a);

okay, but this code takes place in a javascript file and link inside separate webpage. If I echo the php variable into a javascript variable that variable still needs to go into the link.
