app内前h5涉及到支付的功能，ios非实物商品实付需要使用ios原生支付方式，实物商品则可以三方支付，主要的实现思路为后端返回跳转支付宝或微信的支付scheme链接，前端进行跳转支付，同时需要实时查询用户的支付状态。

整个过程中复杂的部分在于查询用户支付状态的体验方面，需要保证用户在支付成功、支付失败、跳转支付宝、微信回来或者没有跳转支付宝微信等未知的行为下的用户体验。

组件内容为底部升起的支付选择弹窗，可以选择支付宝或者微信。

二、实现步骤

用户进行下单操作，前端调用下单接口，成功则返回三方支付app跳转链接，前端进行跳转

跳转三方app同时进行查询订单接口轮训，实时获取订单状态，轮训时间定位30s，依据需求调整

用户如果支付时间超过了30s未返回我们app的情况下，需要针对此种情况进行处理，捕捉用户返回我们app的情况

三、组件可支配参数&事件设置

设置支持参数2个、事件4个，分别为

参数：

successStatus: {default: '1'}, // 支付成功的状态码，默认1errorStatus: {default: '2'} // 支付失败的状态码，默认2

事件：

@payMoney="payMoney" // 下单事件@payStatus="payStatus" //查询支付状态事件@succcessFunction="succcessFunction" // 成功支付操作@errorFunction="errorFunction" // 失败实付操作四、从支付app返回，事件捕获方法

为了防止用户在支付时间超过我们设置轮训时长情况，需要监听用户从支付app返回当前页面，来进行查询支付状态操作。方法为监听页面显示or隐藏事件

reloadState () {// 添加监听器if (typeof document.hidden !== 'undefined') {this.hidden = 'hidden';this.visibilityChange = 'visibilitychange';} else if (typeof document.mozHidden !== 'undefined') {this.hidden = 'mozHidden';this.visibilityChange = 'mozvisibilitychange';} else if (typeof document.msHidden !== 'undefined') {this.hidden = 'msHidden';this.visibilityChange = 'msvisibilitychange';} else if (typeof document.webkitHidden !== 'undefined') {this.hidden = 'webkitHidden';this.visibilityChange = 'webkitvisibilitychange';}document.addEventListener(this.visibilityChange, this.forceUpdate);},forceUpdate () {if (document.visibilityChange === this.hidden) {} else {this.searchTimer();}},五、组件源码<template><div class="pay-info"><div class="pay-content"><span
