electron制作仿制qq聊天界面的示例代码

本文介绍了electron制作仿制qq聊天界面的示例代码，分享给大家，具体如下：
效果图:
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
