我有一个带有日期选择器的输入文本框，当用户选择特定日期时，日期说09-Dec-2014将应用于输入文本框。提交时，我希望将日期以yyyymmdd格式传递给服务器，例如20141209。那么如何在javascript中转换日期格式呢？
var date = new Date(Date.parse('09-Dec-2014'));
Above code gives me 'Invalid date'.

I was able to get the date in yyyymmddformat using the code given below.
我能够使用下面给出的代码以yyyymmdd格式获取日期。
var date = '09-Dec-2014'.split("-");
var months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun','Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'];
for(var j=0;j<months.length;j++){
if(date[1]==months[j]){
date[1]=months.indexOf(months[j])+1;
}
}
if(date[1]<10){
date[1]='0'+date[1];
}
var formattedDate = date[2]+date[1]+date[0];

var date = '09-Dec-2014'.split("-");
var newDate=date[2]+date[1]+date[0];
Something really quick may be, split and generate your own.
可能真的很快，拆分并生成您自己的东西。

The problem lies in the format that you pass the required date to the Date() object.
问题在于您将所需日期传递给 Date() 对象的格式。
For some reason browsers surprisingly do not support the date format “yyyy-mm-dd” and therefore fail.
出于某种原因，浏览器出人意料地不支持日期格式“yyyy-mm-dd”，因此失败。
The following formats are definitely supported across all browsers and would advise sticking to one of these to avoid errors:
所有浏览器都绝对支持以下格式，并建议坚持使用其中之一以避免错误：
var d = new Date(2011, 01, 07); // yyyy, mm-1, dd
var d = new Date(2011, 01, 07, 11, 05, 00); // yyyy, mm-1, dd, hh, mm, ss
var d = new Date("02/07/2011"); // "mm/dd/yyyy"
var d = new Date("02/07/2011 11:05:00"); // "mm/dd/yyyy hh:mm:ss"
var d = new Date(1297076700000); // milliseconds
var d = new Date("Mon Feb 07 2011 11:05:00 GMT"); // ""Day Mon dd yyyy hh:mm:ss GMT/UTC
alert(d.getFullYear()+""+(d.getMonth()+1)+""+((d.getDate()<10)?"0"+d.getDate():d.getDate()));
