然后执行两次检查，一次检查点击的锚点是否已激活，另一次检查是否有任何锚点兄弟处于活动状态。

如果它已经处于活动状态，则表示已经处于活动状态＆＃34;它通过删除类。
如果其中一个兄弟姐妹在点击期间处于活动状态，请不要激活它。
如果它和它的兄弟姐妹都没有活动，请将其激活。

<强> JS

// Add a click listener to the anchors of profile_list
$('#profile_list a').click(function () {
    // Set variables for this,
    // Whether I am the active one,
    // And if there are other active elements in this list
    var a = $(this),
        amIactive = a.hasClass('active'),
        areOthersActive = a.parent().children().hasClass('active');

    // If I'm active
    if (amIactive) {
        // Make me not active when I'm clicked
        a.removeClass('active');
    }
    // Otherwise, if none of my siblings are active
    else if(!areOthersActive){
        // Make me active
        a.addClass('active');
    }
});
