在Meteor中显示客户端上的服务器时间 [英] Display server time on client in Meteor
问题描述
使用Meteor，在显示服务器时间的客户端上保持运行时钟（h：m：s）的有效方法是什么？
Using Meteor, what would be an efficient way to keep a running clock (h:m:s) on the client that displays the server's time?
我发现的JavaScript / PHP答案通常涉及定期获取服务器时间并计算它与客户端之间的差异。
The JavaScript/PHP answers I've found typically involve getting the server time periodically and calculating the difference between that and the client.
Meteor会是什么样子？
What would that look like with Meteor?
更新：自从我最初以来发生了很多变化发布了这个问题。如果您对预构建的解决方案感兴趣，我建议您查看 Meteor Timesync @mizzao。通过在控制台中运行 meteor add mizzao：timesync 来安装它。
UPDATE: A lot has changed since I originally posted this question. If you're interested in a pre-built solution, I recommend taking a look at Meteor Timesync by @mizzao. Install it by running meteor add mizzao:timesync in your console.
推荐答案
David Greenspan在这个关于Spark的演示文稿中获得客户时间14:30。我稍微修改了这段代码以获得服务器端时间：
David Greenspan gets the client time in this presentation on Spark around 14:30. I've modified this code slightly to get server side time:
Javascript：
Javascript:
if (Meteor.isClient) {
Meteor.startup(function () {
setInterval(function () {
Meteor.call("getServerTime", function (error, result) {
Session.set("time", result);
});
}, 1000);
});
Template.main.time = function () {
return Session.get("time");
};
}
if (Meteor.isServer) {
Meteor.methods({
getServerTime: function () {
var _time = (new Date).toTimeString();
console.log(_time);
return _time;
}
});
}
以及HTML：
<body>
{{> main}}
</body>
<template name="main">
{{time}}
</template>
