uniapp默认左滑是关闭整个webview，而不是关闭当前页 实现思路：拦截webview的url跳转操作，将新url用webview组件重新打开，当左滑的时候，默认关闭的就是当前webview，继而跳转到上一次的页面中

<template><view><web-view :src="weburl" :update-title="false" :webview-styles="webviewStyles"></web-view></view>
</template><script>export default {data() {return {// 进度条webviewStyles: {progress: {color: '#FF3333'}},weburl: ""};},onLoad(option) {console.log("接收到的url参数是:", option.weburl); //打印出上个页面传递的参数。this.weburl = option.weburl},onReady() {var pages = getCurrentPages();var page = pages[pages.length - 1];var currentWebview = page.$getAppWebview();var url = currentWebview.children()[0].getURL();console.log('=== url ===', url);var wv = currentWebview.children()[0];wv.overrideUrlLoading({mode: 'reject',match: '.*'}, function(e) {console.log('reject url: ' + e.url);uni.navigateTo({url: `/pages/webbox/webbox?weburl=${e.url}`})});},onBackPress(e) {let pages = getCurrentPages()let page = pages[pages.length - 1];let currentPages = page.$getAppWebview()currentPages.close()return false},onNavigationBarButtonTap() {console.log("点击了标题栏按钮")uni.$emit("showMenu")},methods: {}}
