Question

我想要点击一个＆＃34; li＆＃34; ，＆＃34;＆＃34; activeli＆＃34;＆＃34;课程已添加到此＆＃34; li＆＃34;，但没有奏效。选中的所有项目，此代码的作用类似于jquery中的toggleclass 请帮我。我附上了我的代码（html和css）

＆＃13;

$(function () {
            $(".list-group-item").click(function () {


                if ($(this).hasclass('activeli')) {
                    $(this).removeclass('activeli')
                }
                else {
                    $(this).addclass('activeli')
                }
            });

您使用了错误的关键字＆＃34; hasClass＆＃34;用大写字母C不是＆＃34; hasclass＆＃34;。我还修改了菜单的jquery以便正常工作。

＆＃13;

$(function () {
            $(".list-group-item").click(function () {


                if ($(this).hasClass('activeli')) {
                    $(".list-group-item").removeClass('activeli')
                }
                else {
$(".list-group-item").removeClass('activeli')
                    $(this).addClass('activeli')
                }
            });
        });
