javascript - 如何使用 jquery 选择和删除/隐藏一个 div？

Question

我试图在 AJAX 成功时删除一个 div，但在这样做时遇到了问题。成功后，我看到“已添加”一词出现两次，因为我无法正确选择包含它的 2 个 div。关于如何正确选择它的任何建议？javascript:

 success: function(message){                         
        alert("Deleting!");
        $this.closest('.image').find('.already_fav_content p').removeClass(); #doesn't work

        $this.closest('.image').find('.fav_content p').hide(); #doesn't work

        $this.closest('.image').find('.removebutton').hide(); #works

        $this.closest('.image').find('.already_favorited').removeClass(); #works

        $this.closest('.image').find('.fav').removeClass(); #works


div.fav{
    display: none;
    position:absolute; /* absolute position (so we can position it where we want)*/
    bottom:0px; /* position will be on bottom */
    left: 0px;
    /* styling bellow */
    background-color:#E99C07;
    font-family:  "Arial Black", Gadget, sans-serif;
    font-size:18px;
    font-weight:900;
    color:white;
    opacity:0.75; /* transparency */
    filter:alpha(opacity=70); /* IE transparency */
}
p.fav_content{
    padding:10px;
    margin:0px;
}

div.already_favorited{
    position:absolute; /* absolute position (so we can position it where we want)*/
    bottom:0px; /* position will be on bottom */
    left: 0px;
    /* styling bellow */
    background-color:#E99C07;
    font-family:  "Arial Black", Gadget, sans-serif;
    font-size:18px;
    font-weight:900;
    color:white;
    opacity:0.75; /* transparency */
    filter:alpha(opacity=70); /* IE transparency */
}
p.already_fav_content{
    padding:10px;
    margin:0px;
}                    

html:

<div class="wrapper">

                <!-- image -->
                <div class="image" style="position: relative; left: 0; top: 0;">

                    <!-- already fav div -->
                        <div class="already_favorited">

                        </form>
                    </div>
                    <!-- end munchbutton div -->

                    <!-- fav div -->
                    <div class="fav">
                        <!-- fav content -->
                        <p class="fav_content">Added</p>    <!-- end fav content -->
                    </div>
                    <!-- end fav div -->

                </div>
                <!-- end image div -->

                </div>

Answer 1

它没有失败，因为选择器是错误的

    $this.closest('.image').find('.already_fav_content p').removeClass(); #doesn't work

    $this.closest('.image').find('.fav_content p').hide(); #doesn't work

改成，

    $this.closest('.image').find('p.already_fav_content').removeClass();

    $this.closest('.image').find('p.fav_content').hide();
