uni-app实现返回刷新上一页

方案一

通过监听器实现
page1

uni.$on("refresh", function(data) {if(data.page === "page2") {this.reload()}
})

page2

methods: {handleBack() {uni.$emit("refresh", {page: "page2"})uni.navigateBack()}
}

方案二

通过页面实例实现
page1

methods: {reload() {}
}

page2

methods: {handleBack() {uni.navigateBack({success() {const pages = getCurrentPages()const prevPage = pages[pages.length - 2]prevPage.reload()}})}
}
