单击触发器并关闭同一按钮时，JQuery 动画并打开 div

Question

我有一段 HTML，我希望在单击时为 div 制作动画，并在再次单击时关闭。 HTML:

<a href="#" class="menu_greyed performance_menu_trigger">My Details <span class="push_right">&#x25BC;</span></a>
<div class="performance_menu_holder">
<a href="details" class="push_right performance_menu_item">Details</a>
</div> 

JQuery:

$(document).ready(function(){
        $('.performance_menu_holder').hide()
        $('.performance_menu_trigger').click(function(){
            $('.performance_menu_holder').animate({ "opacity" : "show", bottom: "100" }, 500);
            $('.performance_menu_trigger').addClass('performance_menu_trigger_close');
        });
        $('.performance_menu_trigger_close').click(function(){
            $('.performance_menu_holder').animate({ "opacity" : "show", top: "100" }, 500);
            $('.performance_menu_trigger').removeClass('performance_menu_trigger_close');
        });
    });

当您第一次单击它时，它会按应有的方式打开，但在打开时却不会。它不会关闭 div。

$(document).ready(function(){
        $('.performance_menu_holder').hide()
        $('.performance_menu_trigger').click(function(){
            $('.performance_menu_holder').slideToggle({ "opacity" : "show", bottom: "100" }, 500);
            $('.performance_menu_trigger').addClass('performance_menu_trigger_close');
        });
        $('.performance_menu_trigger_close').click(function(){
            $('.performance_menu_holder').slideToggle({ "opacity" : "show", top: "100" }, 500);
            $('.performance_menu_trigger').removeClass('performance_menu_trigger_close');
        });
    });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<a href="#" class="menu_greyed performance_menu_trigger">My Details <span class="push_right">&#x25BC;</span></a>
<div class="performance_menu_holder">
<a href="details" class="push_right performance_menu_item">Details</a>
</div>

您可以使用slideToggle代替动画。

$(document).ready(function(){
    $('.performance_menu_holder').hide()
    $('.performance_menu_trigger').click(function(){
        $('.performance_menu_holder').slideToggle({ "opacity" : "show", 
bottom: "100" }, 500);

$('.performance_menu_trigger').addClass('performance_menu_trigger_close');
    });
    $('.performance_menu_trigger_close').click(function(){
        $('.performance_menu_holder').slideToggle({ "opacity" : "show", top: "100" }, 500);
        $('.performance_menu_trigger').removeClass('performance_menu_trigger_close');
    });
});
