在顶部和底部div下滚动溢出

Question

我正在使用此Codepen https://codepen.io/Momciloo/pen/bEdbxY中的聊天ui。添加overflow:auto后，左侧边栏中的内容滚动正常并设置滚动div的高度。我似乎无法在右侧聊天部分滚动工作。我希望在输入字段和.top div下滚动聊天气泡。我的第一个解决方案是设置height和overflow-y:scroll，但聊天气泡溢出了ui。我已添加下面的代码段。任何解决方案？

$('.chat[data-chat=person2]').addClass('active-chat');
$('.person[data-chat=person2]').addClass('active');

$('.left .person').mousedown(function(){
    if ($(this).hasClass('.active')) {
        return false;
    } else {
        var findChat = $(this).attr('data-chat');
        var personName = $(this).find('.name').text();
        $('.right .top .name').html(personName);
        $('.chat').removeClass('active-chat');
        $('.left .person').removeClass('active');
        $(this).addClass('active');
        $('.chat[data-chat = '+findChat+']').addClass('active-chat');
    }
});

Answer 1

从你的.container .right .chat.active中删除display flex并添加一个包含所有气泡的包装器div。这个包装器将有一个高度和overflow-y：auto。

检查此codepen https://codepen.io/anon/pen/wzqpoO PS：我只是为了＃34; Thomas Bangalter＆＃34;在你的例子中。您必须调整css属性以适合您的目标。

Answer 2

我认为这是因为你已将justify-content设置为flex-end。 如果你把它设置为初始，它将解决问题。

.container .right .chat {
    justify-content : flex-end;
}

然后在底部放置气泡是下一个问题。 我认为你可以通过将flex-direction设置为column-reverse来解决这个问题。 也许你必须以相反的顺序放置内容。

.container .right .chat {
    justify-content : initial;
    flex-direction: column-reverse;
}
