Extract date and time from string
提问by SuperFunMan
I have a date\time string:
我有一个日期\时间字符串：
Fri Feb 08 2013 09:47:57 GMT +0530 (IST)
2013 年 2 月 8 日星期五 09:47:57 GMT +0530 (IST)
I need to extract the date (02/08/2013) and time (09:47 am) parts and store them in two variables.
我需要提取日期 (02/08/2013) 和时间 (09:47 am) 部分并将它们存储在两个变量中。
Is there an efficient way to do it using JavaScript?
有没有一种使用 JavaScript 的有效方法？
I have written the following code:
我编写了以下代码：
var day = elementDate.getDate(); //Date of the month: 2 in our example
var monthNo = elementDate.getMonth(); //Month of the Year: 0-based index, so 1 in our example
var monthDesc = {'0':'January', '1':'February'}; //, "March", "April", "May", "June", "July", "August", "September", "October", "November", "December");
var year = elementDate.getFullYear() //Year: 2013
var hours = elementDate.getHours();
var mins = elementDate.getMinutes();
var lDateValue = (year.toString() + "-" + monthNo.toString() + "-" + day.toString());
document.getElementById("lDate").value = lDateValue;
I have this in my HTML:
我的 HTML 中有这个：
<input type="date" name="name" id="lDate" class="custom" value=""/>
<input type="time" name="name" id="lTime" class="custom" value="" />
The fields are not getting updated. Am I missing something?
这些字段没有得到更新。我错过了什么吗？

The Date constructor is very good at creating dates from strings:
Date 构造函数非常擅长从字符串创建日期：
Use the following:
使用以下内容：
// This could be any Date String
var str = "Fri Feb 08 2013 09:47:57 GMT +0530 (IST)";
var date = new Date(str);
This will then give you access to all the Date functions (MDN)
这将使您可以访问所有日期功能（MDN）
For example:
例如：
var day = date.getDate(); //Date of the month: 2 in our example
var month = date.getMonth(); //Month of the Year: 0-based index, so 1 in our example
var year = date.getFullYear() //Year: 2013
