electron製作聊天界面(仿製qq)

效果圖:

樣式使用scss和flex佈局

這也是製作IM系統的最後一個界面了!
在製作之前參考了qq和千牛

需要注意的點

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; /*高寬分別對應橫豎滾動條的尺寸*/
    height: 1px;
}

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

滾動條根據時機顯示

其實這個也很簡單用的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;
},

這裏解釋一下爲什麼有一個paddingRight
因爲我們的滾動條是5px 如果不加在滾動條顯示的時候頁面會抖動

簡單寫法

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

頁面滾動

頁面打開的時候消息列表滾動到底部

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

消息發送滾動到底部

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

內容編輯

沒有使用表單元素直接使用的 contenteditable
因爲contenteditable 沒法用雙向數據綁定不過可以用數據偵聽器有很多辦法但是有很簡單的使用input事件就行了
