如何更改日期格式? [英] How to change the date formats?
问题描述
我需要更改日期格式,如果我输入日期为mm / dd / yyyy我需要将其更改为dd / mm / yyyy或者如果我输入日期为dd / mm / yyyy我需要改为m mm / dd / yyyy。
它应该检测输入并相应地改变,是否可能?我怎么能这样做..有人请帮忙..
下面的代码是我的尝试..
var dateformat = row.date_format;
if (dateformat == dd / mm / yyyy) // 检查日期格式//
{
var value = document.getElementById( ' pay_date')。 value ;
var today = new 日期( value < /跨度>);
if ((today.getMonth()+ 1 )< 10)
{
mm = ' 0' +(today.getMonth()+ 1 )
}
else
{
mm =(今天.getMonth()+ 1 )
}
if (today.getDate( )< 10)
{
dd = ' 0' +今天。 getDate()
}
else
{
dd = today.getDate()
}
var yyyy = today.getFullYear();
document.getElementById(' date')。 value = dd + ' /' + mm + ' /' + yyyy;
}
其他
{
myDate = new 日期(document.getElementById(' pay_date')。 value 跨度>);
var day = myDate.getDate();
var month = myDate.getMonth()+ 1 ;
var yr = myDate.getFullYear();
document.getElementById(' pay_date')。 value = month + / + day + / + yr;
}
根据以上所述,如果dateformat是dd / mm / yyyy(之前设置),那么如果我输入mm / dd /中的textfield yyyy格式,然后它应该改变..希望它明确..
以上代码适用于我输入日期为12/03/2011它更改为03/12/2011。
但如果我写了13/12/2011,它会显示NAN / NAN / NAN ..出了什么问题?
function Dateformat(date){
var d = new 日期(parseInt(date.substr( 6 )));
var m,day;
m = d.getMonth()+ 1 ;
if (m < 10 )
m = ' 0' + m
if (d.getDate()< 10 )
day = ' 0' + d.getDate()
else
day = d.getDate();
var formattedDate = m + / + day + / + d.getFullYear();
var hours =(d.getHours()< 10 )? 0 + d.getHours():d.getHours();
var minutes =(d.getMinutes()< 10 )? 0 + d.getMinutes():d.getMinutes();
var formattedTime = hours + : + minutes + : + d.getSeconds();
formattedDate = formattedDate + + formattedTime;
return formattedDate;
}
DateTime dtm = new DateTime ( 2014 , 05 , 15 );
字符串 val = dtm.ToString( dd-mm-yyyy); // 结果:15-05-2014
字符串 val = dtm.ToString( dd / mm / yyyy); // 结果:15/05/2014
字符串 val = dtm.ToString( dd * mm * yyyy); // 结果:15 * 05 * 2014
字符串 val = dtm.ToString( mm-dd -yyyy); // 结果:05-15-2014
String val = dtm.ToString( dd-yyyy-mm); // 结果:15-2014-05
字符串 val = dtm.ToString( yyyy!dd!mm); // 结果:2014!15!05

// 您可以在每个排列和字符拆分器中进行修改
I need to change the date formats as ,if I enter the date as mm/dd/yyyy i need that to be changed to dd/mm/yyyy or if i enter the date as dd/mm/yyyy i need to change to m mm/dd/yyyy.
It should detect the entry and change accordingly,is it possible? how can i do it..anybody please help..
The below code is my try..
var dateformat=row.date_format;
if(dateformat=="dd/mm/yyyy") //checking fot the date format//
{
var value = document.getElementById('pay_date').value;
var today = new Date(value);
if((today.getMonth() + 1)<10)
{
mm='0'+(today.getMonth() + 1)
}
else
{
mm=(today.getMonth() + 1)
}
if(today.getDate()<10)
{
dd='0'+today.getDate()
}
else
{
dd=today.getDate()
}
var yyyy = today.getFullYear();
document.getElementById('date').value=dd + '/' + mm + '/' + yyyy;
}
else
{
myDate = new Date(document.getElementById('pay_date').value);
var day = myDate.getDate();
var month = myDate.getMonth() + 1;
var yr = myDate.getFullYear();
document.getElementById('pay_date').value=month+"/"+day+ "/" +yr;
}
According to above,if the dateformat is dd/mm/yyyy(set before)then if i enter in the textfield in the mm/dd/yyyy format,then it should change..hope its clear..
The above code works when I type date as 12/03/2011 it changes to 03/12/2011.
but if I write 13/12/2011,it shows NAN/NAN/NAN..What is wrong?
function Dateformat(date) { var d = new Date(parseInt(date.substr(6))); var m, day; m = d.getMonth() + 1; if (m < 10) m = '0' + m if (d.getDate() < 10) day = '0' + d.getDate() else day = d.getDate(); var formattedDate = m + "/" + day + "/" + d.getFullYear(); var hours = (d.getHours() < 10) ? "0" + d.getHours() : d.getHours(); var minutes = (d.getMinutes() < 10) ? "0" + d.getMinutes() : d.getMinutes(); var formattedTime = hours + ":" + minutes + ":" + d.getSeconds(); formattedDate = formattedDate + " " + formattedTime; return formattedDate; }
DateTime dtm = new DateTime(2014, 05, 15); String val = dtm.ToString("dd-mm-yyyy");//Result :15-05-2014 String val = dtm.ToString("dd/mm/yyyy");//Result :15/05/2014 String val = dtm.ToString("dd*mm*yyyy");//Result :15*05*2014 String val = dtm.ToString("mm-dd-yyyy");//Result :05-15-2014 String val = dtm.ToString("dd-yyyy-mm");//Result :15-2014-05 String val = dtm.ToString("yyyy!dd!mm");//Result :2014!15!05 . . . . . //you can modify in every arrange and character spliter
