今天给大家分享的是Vue3系列之自定义桌面端对话框组件v3layer。
V3Layer 基于vue3.0构建的多功能PC网页端弹窗组件。拥有超过10+种弹窗类型、30+种参数配置,支持拖拽(自定义拖拽区域)、缩放、最大化、全屏及自定义置顶层叠等功能。
快速引入
在main.js中引入v3layer组件。
import { createApp } from 'vue'
import App from './App.vue'
// 引入Element-Plus组件库
import ElementPlus from 'element-plus'
import 'element-plus/lib/theme-chalk/index.css'
// 引入弹窗组件v3layer
import V3Layer from './components/v3layer'
createApp(App).use(ElementPlus).use(V3Layer).mount('#app')
v3layer支持组件式+函数式两种调用方式。
- 组件式
<v3-layer
v-model="showDialog"
title="标题内容"
content="<div style='color:#f57b16;padding:30px;'>这里是内容信息!</div>"
z-index="2021"
lockScroll="false"
xclose
resize
dragOut
:btns="[
{text: '取消', click: () => showDialog=false},
{text: '确认', style: 'color:#f90;', click: handleSure},
]"
/>
<template v-slot:content>这里是自定义插槽内容信息!</template>
</v3-layer>
- 函数式
let $el = v3layer({
title: '标题内容',
content: '<div style='color:#f57b16;padding:30px;'>这里是内容信息!</div>',
shadeClose: false,
zIndex: 2021,
lockScroll: false,
xclose: true,
resize: true,
dragOut: true,
btns: [
{text: '取消', click: () => { $el.close() }},
{text: '确认', click: () => handleSure},
]
});
当弹窗类型为 message | notify | popover,调用方法如下:
v3layer.message({...})
v3layer.notify({...})
v3layer.popover({...})
vue3.0中提供了
app.config.globalProperties 或 app.provide 两种方式挂载全局函数。
- 如果是 app.config.globalProperties 方式创建:
// vue2中调用
methods: {
showDialog() {
this.$v3layer({...})
}
}
// vue3中调用
setup() {
// 获取上下文
const { ctx } = getCurrentInstance()
ctx.$v3layer({...})
}
- 如果是 app.provide 方式创建:
// vue2中调用
methods: {
showDialog() {
this.v3layer({...})
}
}
// vue3中调用
setup() {
const v3layer = inject('v3layer')
const showDialog = () => {
v3layer({...})
}
return {
v3layer,
showDialog
}
}
参数配置
v3layer支持如下30+参数灵活配置,实现各种弹窗场景。
|props参数|
v-model 是否显示弹框
id 弹窗唯一标识
title 标题
content 内容(支持String、带标签内容、自定义插槽内容)***如果content内容比较复杂,推荐使用标签式写法
type 弹框类型(toast|footer|actionsheet|actionsheetPicker|android|ios|contextmenu|drawer|iframe)
layerStyle 自定义弹窗样式
icon toast图标(loading | success | fail)
shade 是否显示遮罩层
shadeClose 是否点击遮罩时关闭弹窗
lockScroll 是否弹窗出现时将body滚动锁定

time 弹窗自动关闭秒数(1、2、3)
zIndex 弹窗层叠(默认8080)
teleport 指定挂载节点(默认是挂载组件标签位置,可通过teleport自定义挂载位置) teleport="body | #xxx | .xxx"

v3layer支持自定义拖拽区域 (drag:’#aaa’),拖动到窗口外 (dragOut:true)。支持iframe弹窗类型 (type:’iframe’)。
配置 topmost:true 当前窗口会保持置顶。
ok,基于vue3.0开发pc端对话框组件就分享到这里。希望对大家有所帮助哈!
