Passing post parameters with jQuery.post

I have a regular anchor tag which is bound to a $.post() but I'm having trouble wrapping my head around the best way to pass along parameters. Here's what I've got:

<a 
href="ajax/tag_delete.php?id=<?php echo $tag->id;?>" <!-- This feels too "GET" and I don't want to have to parse this query string -->
id="<?php echo $tag->id;?>" <!-- this feels wrong, shouldn't have a number as an id  --> 
class="delete_tag_btn">
delete
</a>

<script>
    $('.delete_tag_btn').bind('click', function(event){
        event.preventDefault();
        $.post( this.href, {/* WHAT IS THE BEST WAY TO GET THESE */}, function(reply) {
            log(reply);

    });
</scirpt>

Any help is much appreciated. Thanks.

$(this).attr('href').split('=')[1]

Of course, that's dependent on your url having a single querystring parameter. If needed, you can get a little more fancy, but this solves your immediate problem.

Edit:

$(document).ready(function(){
    $('.delete_tag_btn').bind('click', function(event){
        event.preventDefault();

        var s = $(this).attr('href').split('?')[1].split('&');
        var a = new Object();

        for(var n = 0; n < s.length; ++n)
        {
            var t = s[n].split('=');
            console.log(String(t[0]));
            a[String(t[0])] = t[1];
        }

        console.log(a);
    });
});

Given the edit, you can specify any number of attributes in your href, which will then be passed to your post. In other words, you can use this function anywhere throughout your application and you don't need to specify which keys to get:

$.post( 
     this.href, 
     data: a, 
     function(reply) {
            log(reply);
});

Actually, that should work. You might need to remove the empty object argument and switch to a .get call...

$.get(this.href, function(reply){
   // Do whatever
});

On the other hand, you can always create an object...

var data = {
   id: $(this).attr('id')
}

Then pass it in your .post call...

$.post(this.href, data, function(reply){
   // Do whatever...
})
