提交没有表格的表格

This might look as the dumb question, but I hope it's not. I have a PHP file delete.php that will delete selected users (it is not ready yet, but I will write it after I finish my HTML model). So, on my HTML model I have the following:

<li><button class="sexybutton">
  <span><span><span class="add">Add</span></span></span>
</button></li>

This sexybutton is the button styling I've downloaded. So, how to make it post the selected user list to a PHP file without putting a <form> tag inside (it will brake all the structure otherwise and will not be valid)?

I could use jQuery (or JS), but I still do not know how to do this. If PHP would have something like "onclick" function :)

Thank you in advance.

You can send an ajax request without a form, like this :

$('.sexybutton').on('click', function() {
    var users = $.map( $('li.users'), function(el) {
       return $(el).text();
    });

    $.ajax({
        url : 'delete.php',
        data: users
    });
});

just create the data you need, and send it ?

<form id="your_form">
<ul>
<li><button class="sexybutton" onclick="$('#your_form').submit();">
  <span><span><span class="add">Add</span></span></span>
</button></li>
</ul>
</form>

explanation:

wrap your existing code with form element, give some unique id to your form (e.g. your_form) and then add attribute onclick to your button and fill it with some jquery syntax (or pure javascript if you wish):

$('#your_form').submit();

this will do the submit job.
