let dateObj = new Date();
let month = monthNames[dateObj.getMonth()];
let day = String(dateObj.getDate()).padStart(2, '0');
let year = dateObj.getFullYear();
let output = month + '\n'+ day + ',' + year;
document.querySelector('.date').textContent = output;

I honestly suggest that you use moment.js. Just download moment.min.jsand then use this snippet to get your date in whatever format you want:
老实说，我建议您使用moment.js。只需下载moment.min.js并使用此代码段以您想要的任何格式获取您的日期：
<script>
$(document).ready(function() {
// set an element
$("#date").val( moment().format('MMM D, YYYY') );
// set a variable
var today = moment().format('D MMM, YYYY');
});
</script>
Use following chart for date formats:
对日期格式使用以下图表：

Use the DOM's getElementByidmethod:
使用 DOM 的getElementByid方法：
document.getElementById("DATE").value = "your date";
document.getElementById("DATE").value = "your date";
A date can be made with the Dateclass:
可以与Date班级进行约会：
d = new Date();
d = new Date();
(Protip: install a javascript console such as in Chrome or Firefox' Firebug extension. It enables you to play with the DOM and Javascript)

You edit an element's valueby editing it's .valueproperty.
您可以value通过编辑元素的.value属性来编辑元素的。
document.getElementById('DATE').value = 'New Value';
