    图片描述

    样式使用scss和flex布局

    这也是制作IM系统的最后一个界面了!
    在制作之前参考了qq和千牛

    需要注意的点

    qq将滚动条美化了 而且在无操作的情况下是不会显示的

    滚动条美化

    ::-webkit-scrollbar { /*滚动条整体样式*/
    width: 5px; /*高宽分别对应横竖滚动条的尺寸*/
    height: 1px;
}

::-webkit-scrollbar-thumb { /*滚动条里面小方块*/
    border-radius: 10px;
    -webkit-box-shadow: inset 0 0 5px rgba(228, 57, 60, 0.2);
    background: rgba(20, 20, 50, 0.6);
    position: absolute;
}

::-webkit-scrollbar-track { /*滚动条里面轨道*/
    -webkit-box-shadow: inset 0 0 5px rgba(228, 57, 60, 0.2);
    border-radius: 10px;
    background: #EDEDED;
    position: absolute;
}

    滚动条根据时机显示

    其实这个也很简单 用的mouseenter 和 mouseleave事件

    <div
    :style="{overflowY:messageScroll? 'auto' : 'hidden',paddingRight: messageScroll ? '0': '5px' }"
    @mouseenter="showMessageScrolls" 
    @mouseleave="hideMessageScrolls">
</div>

# script
 showMessageScrolls(){
     this.messageScroll = true;
},
hideMessageScrolls(){
    this.messageScroll = false;
},

    这里解释一下为什么有一个paddingRight
    因为我们的滚动条是5px 如果不加 在滚动条显示的时候页面会抖动

    简单写法

        @mouseenter="messageScroll = true" 
    @mouseleave="messageScroll = false"

    页面滚动

    页面打开时消息列表滚动到底部

    this.$nextTick(function () {
                this.$refs.msgBox.scrollTop = this.$refs.msgBox.scrollHeight
})

    消息发送滚动到底部

     this.$refs.msgBox.scrollTop = this.$refs.msgBox.scrollHeight;

    内容编辑

    没有使用表单元素 直接使用的 contenteditable
    因为contenteditable 没法用双向数据绑定 不过 可以用数据侦听器 有很多办法 但是有很简单的 使用input事件就行了
