javascript - 单击时的背景颜色 - jQuery

Question

目前，当我点击一个链接时，它会将背景颜色设置为红色。并保持红色。如何仅将 active 链接设置为红色？所以我没有多个红色背景链接。

  $(document).ready(function($) {
    $('.inline').find('.navtoggle').click(function(){
        
      //Expand or collapse this panel
        $(this).css('background-color','red').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;}

Answer 1

在前面加一行:

$('.navtoggle').css('background','none'); // make none before adding bgcolor
$(this).css('background-color','red').next().slideToggle('fast');
