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

vue3.0系列:Vue3自定义PC端弹窗组件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="
这里是内容信息!
"
    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: \'
这里是内容信息!
\', 
    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系列:Vue3自定义PC端弹窗组件V3Layer

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
    }
}
