Delete comment without page refresh

Would like to know how I can improve this code to enable no page refresh when I delete a comment. As its rather annoying if you delete a comment half way down the page and it reverts back to the top.

AJAX

    function delete_(pid){
    $.ajax({
       type: "POST",
       url: "../include/post.delete.php",
       data: "pid="+pid,
       success: function(){
       }
     });
    }

DELETEPOST
    echo'<div class="userinfo"><div id="divider">';

            if($streamitem_data['streamitem_type_id'] == 1||$streamitem_data['streamitem_type_id'] == 3){
                echo "";
                }else{
                echo "";
                }

                $poster_name = _user_core::getuser($streamitem_data['streamitem_creator']);
                $target_name = _user_core::getuser($streamitem_data['streamitem_target']);


            if($streamitem_data['streamitem_type_id'] == 1||$streamitem_data['streamitem_type_id'] == 3){
            if(!($streamitem_data['streamitem_type_id']==1)) {

                echo "<a href='/profile.php?username=".$poster_name['username']."'><img class='stream_profileimage' style='border:none;padding:0px;display:inline;' border=\"0\" src=\"imgs/cropped".$streamitem_data['streamitem_creator'].".jpg\" onerror='this.src=\"img/no_profile_img.jpeg\"' width=\"40\" height=\"40\" ></a>";

            }
                if(!($streamitem_data['streamitem_type_id']==3)) {
                echo "<a href='/profile.php?username=".$poster_name['username']."'><img class='stream_profileimage' style='border:none;padding:0px;display:inline;' border=\"0\" src=\"imgs/cropped".$streamitem_data['streamitem_target'].".jpg\" onerror='this.src=\"img/no_profile_img.jpeg\"' width=\"40\" height=\"40\" ></a>";

                }
                    $cont = stripslashes($streamitem_data['streamitem_content']);

                    if(!($streamitem_data['streamitem_type_id']==1)){
                    //$cont = htmlentities($cont);
                    $cont = ereg_replace("[[:alpha:]]+://[^<>[:space:]]+[[:alnum:]/]","<a class='user_link' href=\"\\0\">\\0</a>", $cont);

                    }


                    if($streamitem_data['streamitem_creator']==$streamitem_data['streamitem_target']){

                    }
                    echo "<br/><a href='#' class='subtleLink' style='font-weight:normal;'>".Agotime($streamitem_data['streamitem_timestamp'])."</a></div><hr><div style='padding-left:10px;padding-right:10px;'>";

                    echo "<span class='subtleLink'>".$cont."</span>";

                        $cont = nl2br($cont);

You need to call .remove() on the comment element you just deleted. You will need to figure out how to identify it. There is one way:

function delete_(pid){
    $.ajax({
       type: "POST",
       url: "../include/post.delete.php",
       data: "pid="+pid,
       success: function(){
           // However you can identify the comment's div, and delete it by calling .remove()
           // This is if it has a unique id
           $("#comment-"+pid).remove();
       }
     });
}

Otherwise, if you used <a href="javascript:delete_(pid);"> you could add a parmeter like <a href="javascript:delete_(pid, this);">. This way you would get to the element via $(the_element_you_passed_to_the_function).parents("div.the-comment-div-parent").remove() for example.

Otherwise you could implement this function right inside the $("a").click(function {}); if you are using this method. It's up to you.
