javascript - Pebble.js 菜单项呈现缓慢

我已经为工作中的服务器创建了一个接口(interface),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,突然间项目不存在了。大约需要 6 秒,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。

这只是处理能力或 pebble.js 脚本的限制,还是我做错了什么?

-- 更新-- 作为 future 的引用,Pebble 的重启使渲染速度显着加快。菜鸟错误...

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'
}, {
title: 'DL 1'
}, {
title: 'DL 2'
}, {
title: 'DL 3'
}, {
title: 'DL 4'
}, {
title: 'EDGER'
}, {
title: 'EPOXYA'
}, {

menu.on('select', function(e) {

var istag = data.match(/<istag>(.*?)<\/istag>/)[1];
istag = istag.replace(/&quot;/g, "\"");
var psname = data.match(/<psname>(.*?)<\/psname>/)[1];

var i2of5status = data.match(/<i2of5status>(.*?)<\/i2of5status>/)[1];

var content = istag + "\n\nPrint Server\n" + psname + "\n" + psip + "\n" + "UPC - " + upcstatus + "\nI2of5 - " + i2of5status;
var detailCard = new UI.Card({
title:e.item.title,
body: content,
scrollable: true,
style: 'small'
});
detailCard.show();
});
});
menu.show();
});

最佳答案

Pebble.js 按需将列表数据流式传输到 watch 。六秒听起来很多,我没有看到那么多的延迟,但除了使用 C SDK 重新构建您的应用程序之外,您无能为力。
