我正在嘗試將紀元時間代碼轉換為人類可讀的結構。我在 stackoverflow 上讀到以下代碼可以工作：鏈接var utcSeconds = 1234567890;var d = new Date(0); // The 0 there is the key, which sets the date to the epochd.setUTCSeconds(utcSeconds);我在 html 文檔內的腳本標記內調用的函數中使用了這種方法，但不知何故我沒有以正確的方式執行此操作。我缺少什么？<html> <head></head> <body> <div class="wrapper"> <div class="box window" id="Window"></div> </div> </div> <script src="https://cdn.jsdelivr.net/npm/[email protected]/web3.min.js"></script> <script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/jquery.min.js"></script> <script> var contract; $(document).ready(function() { var web3 = new Web3(window.web3.currentProvider) var contractAddress = "address"; var abi = [abi]; var contract = new web3.eth.Contract(abi, contractAddress); contract.methods.viewNewestTimestamp().call().then(function(data2) { var utcSeconds = data2; var d = new Date(data2); $('#Window').html(d.utcSeconds(data2)); }) }) </script> </body></html>對于上下文：我正在調用以太坊上的智能合約。智能合約返回以太坊的“現在”值，它是紀元格式的整數，含義如下：1585727288。通過顯示一個長數字，我想顯示一個易于閱讀的日期格式。我怎樣才能做到這一點？:)

你的意思是像
toLocaleString、?toLocaleDateString和/或toLocaleTimeString
const d = new Date(1585740129850);
const options = { weekday: 'long', year: 'numeric', month: 'long', day: 'numeric'};
console.log(d.toLocaleString('de-DE',options),d.toLocaleTimeString('de-DE'))
console.log(
? d.toLocaleDateString(),
? d.toLocaleTimeString('en-US')
)??

我已將其發布在這里： https: //codepen.io/mxnelles/pen/PoqLyPV
function gd(timestamp) {
var date = new Date(timestamp * 1000);
var hours = date.getHours();
var minutes = "0" + date.getMinutes();
var seconds = "0" + date.getSeconds();
var formattedTime = hours + ':' + minutes.substr(-2) + ':' + seconds.substr(-2);
return formattedTime;
}
$(function() {
$("#calc").click(function() {
$("#result").text(gd($("#raw").val()));
})
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div style="padding:30px">
<input type="text" value="1585740248" id="raw">
<button id="calc">Convert Time</button>
<div id="result"></div>
</div>

轉變：
var utcSeconds = 1585740122250;
var somedate = new Date(utcSeconds);
$('#Window').html(somedate.getUTCSeconds()); // format here
格式：
您可以查看：https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toLocaleDateString
var somedate = new Date();
// toLocaleDateString() without arguments depends on the implementation,
// the default locale, and the default time zone
console.log(somedate.toLocaleDateString());
// → "12/11/2012" if run in en-US locale with time zone America/Los_Angeles
