i have a problem with this jquery, in the success function call, its mean to remove the `support' button, and fade in the msg, this is my jquery code:
$('.stats').delegate('.against', 'click', function(e) {
//stop event
e.preventDefault();
// cache a reference to the previous <li> element
// since it is used more than once
var $prevLi = $(this).closest('li').prev('li');
//get the id
var the_id = $prevLi.attr('id').split('_').pop();
//the main ajax request
$.ajax({
context:this,
type: "POST",
data: "action=against&id=" + the_id,
url: "ajax/sa.php",
success: function (msg) {
$prevLi.find("h2.score_down").html(msg).fadeIn();
$(this).closest('li').next().next().find('button').remove(); $(this).remove();
}
});
});
the html:
<ul class="stats">
<li id="topic_20" class="score">
<h2 class="score_up" style="color:green;">10</h2>
<span style="text-align:center;">Supporters</span>
</li>
<li>
<button type="submit" value="Actions" class="support" title="support">
<i></i>
<span>Support</span>
</button>
</li>
<li id="down_20"class="score"><h2 class="score_down">20</h2><span style="text-align:center;">Against</span>
</li>
<li>
<button type="submit" value="Actions" class="against" title="against">
<i></i><span>Against</span></button>
</li>
</ul>
<h3 class="success"></h3>
this jquery is meant to remove the support b开发者_运维技巧utton, when clicked and the new score is meant to fade in! :)) thanks
The button is in the <li>
2 previous to the .against
containing one, so your .next()
calls should be .prev()
, like this:
$(this).closest('li').prev().prev().find('button').remove();
Why not use $("button[type=submit]")? Or just $("button")? If you use the double prev() you're going to have to adjust your code when your markup changes. If you do that often enough, that makes making changes a nightmare later.
