先是报这个错

A parser-blocking, cross site (i.e. different eTLD+1) script, https://api.map.baidu.com/getscript?v=3.0&ak=pgJsRF87Fjia&services=&t=20250225111334, is invoked via document.write. The network request for this script MAY be blocked by the browser in this or a future page load due to poor network connectivity. If blocked in this page load, it will be confirmed in a subsequent console message.

这个js加载太慢终止了 document.write 调用的js,把这个js文件引入先去掉就可以了

<template>
	<view>
		<button  @click="sendMessage" style="z-index: 999999;height: 50px;">Send Message</button>
		<web-view ref="webview" src="http://192.168.1.95:9091/#/pages/index" style="height: 400px;margin-top: 50px;"></web-view>
	</view>
</template>

<script>
	export default {
		data() {
			return {
			}
		},
		methods: {
			sendMessage() {
				//this.$refs.webview.evalJs(`alert('Message from UniApp')`);
				const currentWebview = this.$scope.$getAppWebview();
				const wv = currentWebview.children()[0];
				wv.evalJS(`alert('Message from UniApp')`);
			},
		},
		onReady() {
		    // 确保 web-view 已加载完成
		    setTimeout(() => {
		      this.sendMessage();
		    }, 3000);
		  },
	}
</script>
