介紹
VLayer 一款基於vue.js開發的pc網頁端彈窗元件。集msg|alert|dialog|notify|popover|toast|actionsheet
等眾多功能於一身的漂亮彈框元件。支援拖拽、縮放、最大化|全屏等功能。
如上圖效果,下面就簡單介紹下具體實現過程。
快速引入
在main.js
中全域性引入元件。
import VLayer from './components/vlayer'
Vue.use(VLayer)
vlayer
支援標籤和函式2種寫法。
標籤式寫法
<v-layer
v-model="isConfirm"
title="標題"
content="<div style='color:#06f;padding:10px;'>彈窗內容資訊!</div>"
xclose
z-index="2020"
lockScroll="false"
resize
dragOut
:btns="[
{text: '關閉', click: () => isConfirm=false},
{text: '確定', style: 'color:#f90;', click: handleFn},
]"
/>
函式式寫法
let $el = this.$vlayer({
title: '標題',
content: '<div style='color:#06f;padding:10px;'>彈窗內容資訊!</div>',
xclose: true,
zIndex: 2020,
lockScroll: false,
resize: true,
dragOut: true,
btns: [
{text: '關閉', click: () => { $el.close(); }},
{text: '確定', click: () => this.handleFn()},
]
});

彈窗標題區域預設是可以拖動的,也可以根據需要自定義拖拽手柄 drag: '#xxxx'
,或者設定 drag: false
來禁止彈窗拖拽功能。
設定 dragOut: true
窗體可以拖拽到瀏覽器外部
支援自定義彈窗顯示位置,預設是auto居中
(['150px','100px'] | t | r | b | l | lt | rt | lb | rb
)
<!-- 自定義彈窗位置 -->
<v-layer v-model="showPosition" xclose maximize drag=".dragImg" :position="rb">
<img class="dragImg" src="xxx.jpg" />
</v-layer>
設定 fullscreen: true
一開啟就全屏顯示。maximize: true
開啟最大化按鈕。
ok,今天就分享到這裡。感興趣的同學可以自己動手試試哈!??
最後附上vue移動端彈窗及例項
基於vue.js自定義移動端對話方塊元件VPopup
基於nuxt.js+vue仿微信App介面聊天例項
