Just a few changes to the order of the elements in your HTML and you get the behavior you are looking for. At the start now only 1a and 1b are open. Similarly when you click on 1b now it will close 1a which will hide any open 2a/2b section as well.
只需对 HTML 中元素的顺序进行一些更改，即可获得所需的行为。一开始现在只有 1a 和 1b 是开放的。同样，当您现在单击 1b 时，它将关闭 1a，这也会隐藏任何打开的 2a/2b 部分。
$(document).ready(function() {
$("#acc1").accordion({
active:".ui-accordion-left",
alwaysOpen: false,
autoheight: false,
header: 'a.acc1',
clearStyle: true
});
$("#acc2").accordion({
active:".ui-accordion-left",
alwaysOpen: false,
autoheight: false,
header: 'a.acc2',
clearStyle: true
});
});
<ul id="acc1" class="ui-accordion-container">
<li>
<div class="ui-accordion-left">
