如何使用 Javascript 或 jQuery 从 YYYY-MM-DD HH:MM:SS 修剪 HH:MM:SS

Question

我有一个值格式的表单输入字段：YYYY-MM-DD HH:MM:SS 如何使用 JavaScript 或 jQuery 从上述格式中修剪/删除 HH:MM:SS？

Answer 1

Using split method should do the trick with more than enough extra goodies:

http://www.w3schools.com/jsref/jsref_split.asp

var date = "YYYY-MM-DD HH:MM:SS";
var res = date.split(" ");

res now is an array with "YYYY-MM-DD" and "HH:MM:SS"

Answer 2

 var d = '12/12/1955 12:00:00 AM'; d = d.split(' ')[0]; console.log(d);

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Answer 3

Here's a quick solution. Hope it helps!

 $(document).ready(function () { $("input#someID").val($("#someID").val().substring(0 , 10)); });

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script> <input type = "text" value="2017-01-19 12:10:07" id = "someID">

function getDateFromString(datestring) {
var d = new Date(datestring);
var curr_date = d.getDate();
var curr_month = d.getMonth();
curr_month++;
var curr_year = d.getFullYear();
return curr_date + "-" + curr_month + "-" + curr_year;
}
