如何使用ajax通过GET传递值

Question

Say I have the following, and that I got the IDs dynamically.

<div class="search_results">
<p>user 1 <a href="phpfile.php?id=3">Add</a></p>
<p>user 1 <a href="phpfile.php?id=4">Add</a></p>
</div>

If I didn't use ajax, I could catch the passed values in phpfile.php with $_GET['id'], but how can I use that with jquery?

$.ajax({
    type: 'GET',
    url: 'phpfile.php', // how to add those values here?
    success: function(data) {
        // do smth
    }
});

You need to add the data parameter:

url: 'phpfile.php',
data: {id: 3}

If you have to take the id from the HTML as displayed:

$('.search_results a').click(function (e) {
  e.preventDefault();
  $.ajax({
    type: 'GET',
    url: 'phpfile.php',
    data: {id: $(this).attr('href').match(/id=(\d*)/)[1]},
    success: function (data) {
        // do something
    }
  });
});
