我在每个页面上都有一个 accordion ，但只希望打开适用于该页面所属类别的切换容器，其余的都关闭。我已经研究了两个小时了，还是想不出来。
这是我写的：

$(document).ready(function () {
    $(".toggle-container:not(#commercial:next.toggle_container").hide();
    $("#commercial").addClass("active").children().show();
    $(".trigger").click(function () {
        $(".toggle_container:visible").slideUp('slow');
        $(this).toggleClass("active").next().slideToggle("slow");
        return false;
    });
});

css：

.toggle_container {
    display: none;
}

html片段：

<div class="accordian">
  <h3 id="rack-structures" class="trigger"><a href="#">Rack Structures</a></h3>
  <div class="toggle_container">
    <div class="block">
