How to upgrade H5 hybrid development app

After our app development is completed, it is inevitable that the product will be upgraded in the future, so we hope that the app will be automatically upgraded on the customer's mobile phone, which can be divided into automatic upgrade and manual upgrade. This article mainly introduces how to upgrade the H5 hybrid development app. The editor thinks it is quite good. Now I will share it with you and give you a reference. Let’s follow the editor to take a look, I hope it can help everyone.

Automatic upgrade: usually when the customer app opens the homepage for the first time.

Manual upgrade: Provide an upgrade entrance in the app interface.

The interface effect is demonstrated as follows:

The code is actually very simple, but it needs to be processed separately for ios and android. The basic idea is to obtain the local app version number, and then compare it with the app version number on the server. If it is less than the app version number on the server, then perform an update operation.

var btn = ["确定升级", "取消"];
//获取app系统更新[是否手动点击获取更新]
function appUpdate(ismanual) {
    console.log('appUpdate');
    mui.plusReady(function () {
        plus.runtime.getProperty(plus.runtime.appid, function (inf) {

Our ios application is published in the Apple App Store, while the android application is deployed directly on our own server (such as IIS server), because the android application There are too many markets, so every time you upgrade the version, it will be a very troublesome thing. Every time you release a version, you have to go to all the Android application markets to submit updates.

It should be noted that when calling this method using manual update and automatic update, different parameters must be passed in, because in automatic update, if the system detects that the current version is already the latest version, it will not be displayed on the client. Display, and if it is updated manually, if it is already the latest version, the customer needs to be prompted.

Automatic update call: appUpdate();//Detect app update

Manual update call: appUpdate(true);//Detect app update
