[英]How do you put a variable date on javascript?
I've been trying to use the input data from my HTML to create a date object but no mater what I tweak, it either shows invalid date, or gives today's date.我一直在尝试使用 HTML 中的输入数据来创建日期 object 但无论我如何调整,它要么显示无效日期,要么给出今天的日期。 Any help on how I can solve this?
关于如何解决这个问题的任何帮助? Or corrections on what I may be doing wrong?
或者更正我可能做错了什么? Thanks.
谢谢。 Here's my code below.
下面是我的代码。
<input type="date" id="date">
<script>
var date = document.getElementById("date").value();
var d = new Date(d);
</script>
You put wrong.value() change to.value.你把 wrong.value() 改成 .value。
You can use momentjs to format date YYYY-MM-DD您可以使用 momentjs 格式化日期 YYYY-MM-DD
function check(){
var date = document.getElementById("date").value;
var d = new moment(date, 'YYYY-MM-DD');
console.log(d)
}
function check(){ var date = document.getElementById("date").value; var d = new moment(date, 'YYYY-MM-DD'); console.log(d) }
<input type="date" id="date" onblur="check()"> <script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.24.0/moment.min.js" integrity="sha256-4iQZ6BVL4qNKlQ27TExEhBN1HFPvAvAMbFavKKosSWQ=" crossorigin="anonymous"></script>
May be helpful to you:可能对您有帮助:
function x(){ var date = document.getElementById("date").value; var d = new Date(date); console.log(d); }
<input type="date" id="date"> <button onclick="x()">show</button>
You can try the following:您可以尝试以下方法:
<!DOCTYPE html>
<html>
<head>
<title>Date experiment</title>
<script>
function processDate(mdate){
console.log(mdate);
}
</script>
</head>
<body>
<p>This is a paragraph.</p>
<form>
Date : <br>
<input type="date" id="start" name="mydate" onchange="processDate(this.value)"
value="2019-10-20" min="2019-10-01" max="2019-12-31">
</form>
</body>
</html>
