效果如下:

<web-view :src=""></web-view>

onReady(() => {
	let pages = getCurrentPages();
	let page = pages[pages.length - 1];
	let currentWebview = page.$getAppWebview();
	setTimeout(function() {
		const wv = currentWebview.children()[0]
		//setStyle设置webview的宽高的位置
		wv.setStyle({
			top: 125,
			left: 70,
			height: 520,
			width: 895
		})
	}, 1000);
})
