uniapp App页面通过 web-view 调用网页内方法

先是报这个错

排查发现可能是

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>
