我已经为工作中的服务器创建了一个接口,以验证打印服务器和打印机是否动态启动,并将其反馈给 Pebble。功能很好,我遇到的问题是菜单。我将加载菜单,然后开始向下滚动,突然项目不存在。大约需要 6 秒钟,然后它们就会出现。上下滚动都是如此。有很多菜单选项,但即使菜单中有六个项目也可以。

这只是处理能力的限制,还是 pebble.js 脚本,还是我做错了什么?

-- 更新 -- 为了将来参考,重新启动 Pebble 使渲染速度显着加快。菜鸟的错...

var UI = require('ui');
var ajax = require('ajax');

var main = new UI.Card({
  title: 'Pebble Interface',
  icon: 'images/mattec.png',
  body: 'Press Top Button to open Cell Picker.'
});

main.show();

main.on('click', 'up', function(e) {
  var menu = new UI.Menu({
    sections: [{
        items: [{
          title: 'ALMSC1'

          title: 'ALMSC2'

Pebble.js 按需将列表的数据流式传输到手表。六秒听起来很长,我没有看到太多延迟,但除了使用 C SDK 重新构建应用程序之外,您无能为力。
