function displayinTextbox(){
          var datetodisplay = new Date('2014/01/01'); //i want to convert it first in this format (January 1 2014)

function displayinTextbox(){
    var datetodisplay = new Date('2014/01/01');
    var months = ["January", "February", "March", "April", "May", "June", "July", August", "September", "October", "November", "December"];
    var convertedDate = months[datetodisplay.getMonth()] + " " + datetodisplay.getDate() + " "+datetodisplay.getUTCFullYear();
    document.getElementById('date').value = convertedDate ;
}

Answer 2

试试这个：

function displayinTextbox(){
    var datetodisplay = new Date('2014/01/01');
    var convertedDate = datetodisplay.toDateString();
    document.getElementById('date').value = convertedDate ;
}

Answer 3

getDate(): Returns the day of the month.
getDay(): Returns the day of the week. The week begins with Sunday (0 - 6).
getFullYear(): Returns the four-digit year.
getMonth(): Returns the month.
getYear(): Returns the two-digit year.
getUTCDate(): Returns the day of the month according to the Coordinated Universal Time (UTC).
getUTCMonth(): Returns the month according to the UTC (0 - 11).
getUTCFullYear(): Returns the four-digit year according to the UTC.

Answer 4

Date对象提供various methods来访问制作日期/时间数据的不同部分。

在您的情况下，将月份显示为名称而不是数字需要将月份值（从0到11）映射到月份名称（从＆＃34; 1月和＃34;到＆＃34; 12月和＃34 ;）

var monthNames = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"];
var convertedDate = monthNames[dateToDisplay.getMonth()] + " " + dateToDisplay.getDate() + " " + "dateToDisplay.getFullYear();

如果你必须处理多种语言并且＆＃34;漂亮＆＃34;格式，您可能需要查看格式库，例如Moment.js。

Answer 5

我建议您使用Moment.js库。

你需要的东西可以简单地用Moment.js完成。

var str = '2014/01/01';
var formatted = moment(str, 'YYYY/MM/DD').format('MMMM D YYYY');
console.log(formatted);
