我有一个简单的文档，下面的代码中给出了它的mwe。在左表单元格和右表单元格中；8月27日上午8时"；，并且在中间小区中；LT 8月26日1800时"；例如日期每天都会变化。我看过的所有帖子都对我没有真正的帮助。我会感谢你的帮助。Zilore Mumba

Ciao，通过使用moment，您可以将今天日期(moment()(和昨天日期(moment().subtract(1, "days")(设置为您需要的格式(format('D MMM')(，如下所示：

(function() {
document.querySelectorAll("#today").forEach(el => {
el.innerHTML = moment().format('D MMM');
});
document.getElementById("yesterday").innerHTML = moment().subtract(1, "days").format('D MMM');
})();
