在JS中获取经过的时间 [英] Getting Elapsed Time in JS

问题描述

小提琴

我正在建立一个社交网络，当您发布内容时，我想显示时间.我有当前的代码来显示时间(这不仅是时间，它还在验证和发布文本):

I am making a social network and when you post something, I want to show the time. I have the current code to display the time (this isn't only the time, it's also validating and posting the text):

$('#b').click(function () {
    var v = $('#type').val();
    var u = $('#input').val();
    if (v !== "" && u !== ""){
        var time = new Date();
        var currentime = Date.now();
        var x = currentime - time;
        $("ul").prepend("<li>" + v + "<br />Posted by " + u + " " + x +" minutes ago  </li>");
        $('#type, #input').css('border','');
    }
    else if (v == "" && u == "") {
        $('#type, #input').css('border','1px solid red');
    }
    else if (v == "") {
        $('#type').css('border','1px solid red');
        $('#input').css('border','');
    }
    else {
        $('#input').css('border','1px solid red');
        $('#type').css('border','');
    }
});

时间到了，它说的是0分钟前(就像我告诉过的那样)，但是经过一定时间后，它仍然是0.

When the time posts, it says 0 minutes ago (like I told it to), but after any amount of time, it still says 0.

推荐答案

基本上，您可以设置 setInterval 通常您会更新时间属性.我将span与类.time一起使用，因此从理论上讲，您可以随时间更新任何内容.

Basically you set up a setInterval which governs ho frequently you update your time attribute. I used a span with a class .time to so you could theoretically update anything with time.

我会进一步对您的帖子进行哈希处理，以便您可以轻松地检索每个帖子的原始时间.

I would go further and hash your posts so you can easily retrieve each posts original time.
