单击时下拉菜单不起作用，所有菜单都下拉

Question

我正在为我的网站制作一个点击脚本的下拉菜单，但它并没有完全按照我想要的方式工作。 (http://blazebass.com/version2/?pagina=blazers)

当我点击按钮 1 时，按钮 2 也会下降。我不想要这个。

页面代码如下：

<TABLE BORDER="0" align="center">
<TR><TD>    

<div class="click-nav">
<ul class="no-js">
<li>
<div class="button_blazer"><a class="clicker"><font color="white">VANCED (Producer / DJ)                </font></a></div>
<ul>
<li class="button_content">

<div class="soundcloud"><center><b><a href="http://www.soundcloud.com/vanced"         target="_new">SOUNDCLOUD</a></b></center></div>
<div class="facebook"><center><b><a href="https://www.facebook.com/vanceddubstep"     target="_new">FACEBOOK</a></center></div>

Answer 1

您可以通过e.currentTarget 访问您点击的元素，这样您就可以从本质上将您的侦听器更改为如下内容：

$('.click-nav .js').click(function(e) {
    $('ul', e.currentTarget).slideToggle(200);
    $('.clicker', e.currentTarget).toggleClass('active');
    e.stopPropagation();
});

它的作用是将“ul”和“.clicker”之后的搜索限制在实际点击的区域。

另外，作为提示，您应该在代码中使用缩进，因为它很难阅读。
