uniapp配置全局消息提醒
1.H5使用根标签插入dom的方式实现。
2.app端使用plus.nativeObj.View的方式绘制实现
H5端
创建组件orderAlert.vue
<template>
<div class="view">
<div class="content" v-if="visible">
<div class="message">{{ message }}</div>
</div>
</div>
</template>
<script>
export default {
data() {
return {
visible:false
}
},
props: ['message'],
methods: {
open() {
this.visible = true;
},
close() {
this.visible = false;
console.log(this.visible);
}
}
}
</script>
<style lang="stylus" scoped>
.content {
position: absolute;
top: 70rpx;
left: 0%;
width: 100%;
background-color: #ea3e49;
border-radius: 10rpx;
color: #fff;
opacity: 0.95;
z-index: 1000000;
.message {
line-height: 50rpx;
font-weight: 700;
font-size: 18rpx;
text-align: center;
}
}
</style>
创建createDialog.js
import { createVNode, render } from 'vue';
import orderAlert from '@/components/common/orderAlert/orderAlert.vue';
export function createDialog(options) {
console.log(options);
// 创建 DOM 容器
const container = document.createElement('div');
document.getElementById('app').appendChild(container);
// 创建组件实例
const vnode = createVNode(orderAlert, {
...options,
onClose: () => {
// 销毁组件
render(null, container);
document.body.removeChild(container);
}
});
// 渲染组件
render(vnode, container);
// 获取组件实例
const instance = vnode.component?.proxy;
console.log(instance);
// 返回组件实例以调用 open 方法
instance.open();
setTimeout(()=>{
instance.close()
},3000)
return instance;
}
全局调用
import {
createDialog
} from “@/utils/createDialog.js”
createDialog({
message: 'hello'
})
app端
创建nativePanel.js
let nativePanel = null;
