electron制作仿制qq聊天界面的示例代碼

更新時(shí)間：2018年11月26日 10:39:29 作者：李昊天

這篇文章主要介紹了electron制作仿制qq聊天界面的示例代碼，小編覺得挺不錯的，現(xiàn)在分享給大家，也給大家做個(gè)參考。一起跟隨小編過來看看吧

本文介紹了electron制作仿制qq聊天界面的示例代碼，分享給大家，具體如下：

效果圖:

樣式使用scss和flex布局

這也是制作IM系統(tǒng)的最后一個(gè)界面了!

在制作之前參考了qq和千牛

需要注意的點(diǎn)

qq將滾動條美化了而且在無操作的情況下是不會顯示的

滾動條美化

::-webkit-scrollbar { /*滾動條整體樣式*/
  width: 5px; /*高寬分別對應(yīng)橫豎滾動條的尺寸*/
  height: 1px;
}

::-webkit-scrollbar-thumb { /*滾動條里面小方塊*/
  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 { /*滾動條里面軌道*/
  -webkit-box-shadow: inset 0 0 5px rgba(228, 57, 60, 0.2);
  border-radius: 10px;
  background: #EDEDED;
  position: absolute;
}

滾動條根據(jù)時(shí)機(jī)顯示

其實(shí)這個(gè)也很簡單用的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;
},

這里解釋一下為什么有一個(gè)paddingRight

因?yàn)槲覀兊臐L動條是5px 如果不加在滾動條顯示的時(shí)候頁面會抖動

簡單寫法

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

頁面滾動

頁面打開時(shí)消息列表滾動到底部

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

消息發(fā)送滾動到底部

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

內(nèi)容編輯

沒有使用表單元素直接使用的 contenteditable

因?yàn)閏ontenteditable 沒法用雙向數(shù)據(jù)綁定不過可以用數(shù)據(jù)偵聽器有很多辦法但是有很簡單的使用input事件就行了
