uniapp introduces online js link

Due to the use of script tags in index.html in the uniapp project, the introduction is invalid

Solution:

Add in the app.vue page

<script>
	export default {
		onLaunch:function(){
		 var script = document.createElement('script');
		 script.src = "https://xxx.js";
		 document.head.appendChild(script);
		}
	}
</script>
