javascript - 使用 jQuery 单击链接时更改链接背景颜色

Question

我有一个基本的 jQuery Accordion 。如果单击该链接，我想更改该链接的背景颜色。

因此，如果我单击“下拉菜单 1”，背景颜色将变为红色。我该怎么做？

演示: http://jsfiddle.net/4dm318nn/

  $(document).ready(function($) {
    $('.inline').find('.navtoggle').click(function(){

      //Expand or collapse this panel
      $(this).next().slideToggle('fast');

      //Hide the other panels
      $(".sub-menu").not($(this).next()).slideUp('fast');

    });
  });

  .accordion-toggle {cursor: pointer;}
  .sub-menu {display: none;}
  .sub-menu .sub-menu {display: block;}
