格式化在javascript日期

我知道在JavaScript Date对象其他可能的格式，但我并没有对如何格式化日期以获得MM/dd/yyyy HH:mm:ss格式。

请让我知道，如果你遇到这样的问题。

Answer 1:

尝试这样的事情

var d = new Date,
    dformat = [d.getMonth()+1,
               d.getDate(),
               d.getFullYear()].join('/')+' '+
              [d.getHours(),
               d.getMinutes(),
               d.getSeconds()].join(':');

如果你想前导零的值<10，使用这个号码扩展

Number.prototype.padLeft = function(base,chr){
    var  len = (String(base || 10).length - String(this).length)+1;
    return len > 0? new Array(len).join(chr || '0')+this : this;
}
// usage
//=> 3..padLeft() => '03'
//=> 3..padLeft(100,'-') => '--3' 

适用于以前的代码：

var d = new Date,
    dformat = [(d.getMonth()+1).padLeft(),
               d.getDate().padLeft(),
               d.getFullYear()].join('/') +' ' +
              [d.getHours().padLeft(),
               d.getMinutes().padLeft(),
               d.getSeconds().padLeft()].join(':');
//=> dformat => '05/17/2012 10:52:21'

Answer 2:

var d = new Date();
alert(
    ("00" + (d.getMonth() + 1)).slice(-2) + "/" + 
    ("00" + d.getDate()).slice(-2) + "/" + 
    d.getFullYear() + " " + 
    ("00" + d.getHours()).slice(-2) + ":" + 
    ("00" + d.getMinutes()).slice(-2) + ":" + 
    ("00" + d.getSeconds()).slice(-2)
);

Answer 3:

var d = new Date();

var curr_date = d.getDate();

var curr_month = d.getMonth();

var curr_year = d.getFullYear();

document.write(curr_date + "-" + curr_month + "-" + curr_year);

使用此您可以格式化日期。

Answer 4:

var d = new Date();

// calling the function
formatDate(d,4);


function formatDate(dateObj,format)
{
    var monthNames = [ "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" ];
    var curr_date = dateObj.getDate();
    var curr_month = dateObj.getMonth();
    curr_month = curr_month + 1;
    var curr_year = dateObj.getFullYear();
    var curr_min = dateObj.getMinutes();
    var curr_hr= dateObj.getHours();
    var curr_sc= dateObj.getSeconds();
    if(curr_month.toString().length == 1)
    curr_month = '0' + curr_month;      
    if(curr_date.toString().length == 1)
    curr_date = '0' + curr_date;
    if(curr_hr.toString().length == 1)
    curr_hr = '0' + curr_hr;
    if(curr_min.toString().length == 1)
    curr_min = '0' + curr_min;

    if(format ==1)//dd-mm-yyyy
    {
        return curr_date + "-"+curr_month+ "-"+curr_year;       
    }
    else if(format ==2)//yyyy-mm-dd
    {
        return curr_year + "-"+curr_month+ "-"+curr_date;       
    }
    else if(format ==3)//dd/mm/yyyy
    {
        return curr_date + "/"+curr_month+ "/"+curr_year;       
    }
    else if(format ==4)// MM/dd/yyyy HH:mm:ss
    {
        return curr_month+"/"+curr_date +"/"+curr_year+ " "+curr_hr+":"+curr_min+":"+curr_sc;       
    }
}
