uniapp定义new plus.nativeObj.View实现APP端全局弹窗

为什么要用new plus.nativeObj.View在APP端实现弹窗？因为uni.showModal在APP端太难看了。

AppPopupView弹窗函数参数定义

参数一:弹窗信息(所有属性可不填，会有默认值)

1.title:"", //标题

2.content:"", //内容

3.confirmBoxColor:"", //确认按钮背景色

4.cancelText:"", //取消按钮文字

5.confirmText:" //确认按钮文字"

6.showCancel: false, // 是否显示取消按钮是:true(默认) 否:false

7.maskClick: true // 是否允许点击遮罩层关闭弹窗是:true 否:false(默认)

参数二(cd1):点击确认按钮执行逻辑，

参数三(cd2):点击取消按钮执行逻辑。

/utils/AppPopupView.js 定义弹窗文件

复制代码

export default AppPopupView
 
function AppPopupView({
	title = '提示',
	content = '',
	confirmBoxColor = '#41a863',

	maskLayer.addEventListener("click", function() { //处理遮罩层点击
		if (maskClick) {
			maskLayer.hide();
			popupView.hide();
		}
	})
 
	// 显示弹窗
	maskLayer.show()
	popupView.show()
}

在main.js挂载到全局

复制代码

// #ifdef APP-PLUS
import AppPopupView from '@/utils/AppPopupView.js';
Vue.prototype.AppPopupView = AppPopupView;
// #endif

页面调用全局弹窗

复制代码

<script>
	export default {
		onLoad() {
			// #ifdef APP-PLUS
			// 参数一:弹窗信息(所有属性可不填，会有默认值)
			let AppPopupInfo = {
				// title:"", //标题
				// content:"", //内容
				// confirmBoxColor:"", //确认按钮背景色
				// cancelText:"", //取消按钮文字
				// confirmText:" //确认按钮文字",  
				// showCancel: false, // 是否显示取消按钮 是:true(默认) 否:false
				// maskClick: true // 是否允许点击遮罩层关闭弹窗 是:true 否:false(默认) 
			}
			// 参数二:点击确认按钮执行逻辑
			const affirmBtn = () => {
				console.log("点击了确认按钮");
			}
			// 参数三:点击取消按钮执行逻辑
			const cancelBtn = () => {
				console.log("点击了取消按钮");
			}
			this.AppPopupView(AppPopupInfo, affirmBtn, cancelBtn)
			// #endif
		},
	}
</script>
