UpdateManager.onUpdateFailed

Introduction

Listen for the mini-program update failure event. When a new version of the mini-program is available, the client actively triggers the download (without the need for the developer to trigger it), and if the download fails (due to reasons such as network issues), this callback is executed.

Parameters

None

Sample Code

Page({
  onLoad() {
    const updateManager = dlt.getUpdateManager();
    updateManager.onUpdateFailed(function (res) {
      // New version download failed
    });
  },
});
