JavaScript - I Have A Function To Display The Date In A Certain Format. What Am I Doing Wrong?

I've been trying to change the way a date appears.

The JS gives the date Easter will fall in a particular year. That works but the format that appears is this;
Sun Apr 24 00:00:00 EDT 2011

I'm trying to get it to read like this:
Sunday, April 24, 2011

I've been racking my brain all morning and can't seem to get it right.

Very limited experience in JS doesn't help either. Could somebody take a look and see where I messed up.

Thanks in advance.

Code:

 easterYear = 2011;    
  var a, b, c, d, e, f, g, h, i, k, l, m, easterMonth, easterDate;     
  a = parseInt(easterYear % 19);     
  b = parseInt(easterYear / 100);     
  c = parseInt(easterYear % 100);     
  d = parseInt(b / 4);     
  e = parseInt(b % 4);     
  f = parseInt((b + 8) / 25);     
  g = parseInt((b - f + 1) / 3);     
  h = parseInt((19 * a + b - d - g + 15) % 30);     
  i = parseInt(c / 4);     
  k = parseInt(c % 4);     
  l = parseInt((32 + 2 * e + 2 * i - h - k) % 7);     
  m = parseInt((a + 11 * h + 22 * l) / 451);     
  easterMonth = parseInt((h + l - 7 * m + 114) / 31);     
  easterDate = parseInt(((h + l - 7 * m + 114) % 31) + 1);     
  

var dayName = new Array
  ("Sunday","Monday","Tuesday","Wednesday",
  "Thursday","Friday","Saturday");

var monthName=new Array
  ("January","February","March","April","May",
  "June","July","August","September","October",
  "November","December");

var now = new Date();
var gplMonth = monthName[easterMonth-1];
var gplDay = dayName[0];
 //gplDay ;

var gplDate = new Date();
var gplDt = gplDate.getDate();

document.write(new Date(easterYear , easterMonth - 1, easterDate) );  // Original line
document.write('<br />' )

document.write( gplDay  + ",  " + gplMonth + " " + easterDate + ",  " + easterYear)
document.write('<br />' )
document.write(gplMonth + " " + easterDate )
document.write('<br />' )

I'm not too sure how to approach this but I have a date input that uses a jQuery pop-up for a calendar, and enters the date in a format d MMM yy (1 Jan 11).

Not everyone wants to be clicking and choosing the date from the calendar but to be entering it just as a number such as 0101, 010111 or 01012011 which can be faster. This would then need to be converted to the d MMM yy format as per the jQuery pop-up when they exit the input box.

So really only if it's a number format it needs to look at the number of digits... and does the conversion.

Has anyone done something like this before? Or is there a link to how I could go about achieving this?

Many thanks

David

Hello, I am using jQuery to set a cookie and the expiration date is:

Code:

date.setTime(date.getTime() + (options.expires * 24 * 60 * 60 * 1000));

which lasts for 1 day, but I would like the cookie to not expire for a long time, is this possible? I know google has one that like expires in 2035 or something but I would like this on to last long. What should I do?

Hello, I would like to learn if there is way to change a different format every time the user want as example is
Code:

London 12:00:33 - Friday 18/03/2011

Thanks

Hi All,

I have a snippet of Javascript that changes date format from yyyy/mm/dd to dd/mm/yyyy:

Code:

<script type="text/javascript">
var myString = "[[date]]";
var mySplitResult = myString.split("-");document.write(mySplitResult[2] + "/" + mySplitResult[1] + "/" + mySplitResult[0] );
</script>

However, I want it to return the format as dd/mm/yy (the last two number of the year rather than the full four).

Is this possible to do?

Thanks,
Neil

hello,

is there a date format for an existing date?

all I see is a var d = new Date();

but i need to format an existing date?

thanks!

I have a calendar and when selecting the date the date format inserted to text box is in the format ' 10/10/2010'. This is not getting inserted into oracle database. Oracle accepts only the format '10-OCT-10' . So please help me to change the format of date that getting selected from calendar.

Hello

I am trying to change the default date format within my date picker, but nothing I do seems to work.

This is the relevant Code:

Code:

$(function() {
	Date.format = 'yy-mm-dd';
	$('#popupDatepicker').datepick();
});
 

<p><b>Date Of Birth:</b><input type="text" name="dob" id="popupDatepicker"><br>

All I see is dd/mm/yy no matter what I change

I need it in a format suitable for MySQL

Thanks

I have a database script that returns dates in the following format:

yyyy-mm-dd

I have been using the following code to change this format to dd-mm-yyyy:

Code:

<script type="text/javascript">
var myString = "[[date]]";
var mySplitResult = myString.split("-");document.write(mySplitResult[2] + "/" + mySplitResult[1] + "/" + mySplitResult[0] );
</script>

However, I now want to display the date in text format, e.g. 01-08-2009 would be displayed as 01 August 2009.

Could anyone please let me know how I change the script to show this format?

Many thanks in advance,
Neil

Hi Chaps,

I have a Javascript ActiveX function that exports the contents of an HTML table into MS Excel. The script works fine, however, some of the dates have changed from dd/mm/yyyy to mm/dd/yyyy. I do not know why this is happening, especially as it's only to a few.
Here is the code:
Code:

<script language="javascript" type="text/javascript">  
function ExportToExcel() {
	input_box=confirm("Export to Microsoft Excel?");
		if (input_box==true) {
			
			var xlApp = new ActiveXObject("Excel.Application");
			// Silent-mode:
			xlApp.Visible = true;
			xlApp.DisplayAlerts = false;
			var xlBook = xlApp.Workbooks.Add();
			xlBook.worksheets("Sheet1").activate;
			var XlSheet = xlBook.activeSheet;
			XlSheet.Name="Report";
			
			// Store the sheet header names in an array
			var rows = tblreport_work.getElementsByTagName("tr");
			var columns = tblreport_work.getElementsByTagName("th");
			var data = tblreport_work.getElementsByTagName("td");
			
  			// Set Excel Column Headers and formatting from array
			for(i=0;i<columns.length;i++){

Date Columns: F,G,I

If anyone has some ideas on how to correct this, I'd be most grateful!

Hi,

I am trying to get the current date by using this date() but It giving me inconsistent behaviour. Sometime it's giving the correct value but some time it's giving me Jan 1 1970 . I am not able to understand this behaviour as Date() is fetching the system date only there is no other dependency . I tried in these way

Code:

this.hoy =new Date();
 alert( " ************************** Main class ********************");
    alert("Day is : "  + this.hoy.getDay() );
    alert("Month  is : "  + this.hoy.getMonth() );
    alert("Full year is : "  + this.hoy.getFullYear() );
   alert("Date is : "  + this.hoy.getDate() );
alert( " **************************timestamp Main class ********************");
    var timestamp = new Date(new Date().getTime() + 3600000  );
    
    alert("timestamp Day is : "  + timestamp.getDay() );
    alert("timestamp Month  is : "  +timestamp.getMonth() );
    alert("timestamp Full year is : "  +timestamp.getFullYear() );
    alert("timestamp Date is : "  + timestamp.getDate() );
     alert( " **************************UTC Main class ********************");
     alert("UTC Day is : "  + timestamp.getUTCDay() );
    alert("UTC Month  is : "  +timestamp.getUTCMonth() );
    alert("UTC Full year is : "  +timestamp.getUTCFullYear() );
    alert("UTC Date is : "  + timestamp.getUTCDate() );

and the wrong output which I got that is : Quote:
alert() : ************************** Main class ********************
alert() : Day is : 4
alert() : Month is : 0
alert() : Full year is : 1970
alert() : Date is : 1
alert() : **************************timestamp Main class ********************
alert() : timestamp Day is : 4
alert() : timestamp Month is : 0
alert() : timestamp Full year is : 1970
alert() : timestamp Date is : 1
alert() : **************************UTC Main class ********************
alert() : UTC Day is : 4
alert() : UTC Month is : 0
alert() : UTC Full year is : 1970
alert() : UTC Date is : 1

I did googling but didn't find any solution just got the idea that date() calculate date in milisecond from 1st Jan 1970 but why I am getting this no idea .

And why sometime getting wrong output or some time right.

Please help me out struck badly here.

Thanks in advance

I set up the following code to check how many days have elapsed since a file has been uploaded:

Code:

function fileModified(url){
    try{
        var Oxml= new window.XMLHttpRequest();
        Oxml.open("HEAD", url, false);
        Oxml.send(null);
        if(Oxml.status== 200){
            var lastmod = Oxml.getResponseHeader('Last-Modified');
            return lastmod;
        }
        else return null;
    }
    catch(er){
        return null;
    }
}
modified = fileModified(location.href);
var now = new Date();
var msecsPerDay = 1000 * 60 * 60 * 24;
var msecsDiff = now.getTime() - modified.getTime();
var diff= msecsDiff / msecsPerDay ;

alert("Days since file was uploaded="+diff);

My problem is that modified.getTime() doesn't work. Apparently the result of Oxml.getResponseHeader('Last-Modified') is a string, such as Sun, 21 Nov 2010 21:17:49 GMT.

I tried and tried - but couldn't get to make a proper date out of this.

The final result that I need is the time since the file was uploaded.

Thanks!

For the sample code:

Code:

<form name=form>
<ul>
<li><input type="text" onkeyUp="calc1();" name=x ></li>
<li><input type="text" onkeyUp="calc2();" name=y ></li>
</ul>
</form>

<script>
function calc1() {
    document.form.y.value = (10 * document.form.x.value).toPrecision(5);
}
function calc2() {
    document.form.x.value = (0.1 * document.form.y.value).toPrecision(5);
}
</script>

How can I use a checkbox to :

(1) Upon check, change the current values to toExponential(5) format
(2) Use a different script and/or function that would then calculate with toExponential(5) [as opposed to the hard coded toPrecision(5) in the current functions.
(3) Upon unchecking, the result should should go back to Precision and change the function and/or script back to the original.

I put the following line in the onchange tag of a listbox to use the values to manipulate an iframe:
document.getElementById('viewer').src=('Location_Files/')+(this.value)+('.htm')

There it works perfectly but I wanted to do more so I decided to build a function around it:

function display()
{
document.getElementById('viewer').src=('Location_Files/')+(this.value)+('.htm')
}

When I put the function in the onchange tag instead, the iframe tries to work but I get a "can't load page" message like the src is broken. Now when I first made that line it took me hours to figure out that I can't use a "\" because if I do it fails. So I went with "/" and that works but I wonder if that rules change when I specify it in the java script instead of in the onchange tag itself. Either way it still breaks if I try to use "\".
Does anyone see the problem?

I can't get the

function getchecked() to show

an alert box...

Code:

<script>
function getCheckedValue(radioObj) {
	if(!radioObj){
		return "";
       }
	var radioLength = radioObj.length;
	if(radioLength == undefined){
		if(radioObj.checked){
			return radioObj.value;
		}else{
			return "";
                }
        }
	for(var i = 0; i < radioLength; i++) {
		if(radioObj[i].checked) {
			return radioObj[i].value;
		}
	}
	return "";
}
}
function getchecked(){
var thecode=getCheckedValue(document.forms['radioExampleForm'].elements['code']);
if(thecode!==""){
if(thecode=="HTML"){
alert('Checked value is: '+thecode+'.');
//playSound("test1.mp3");
}else if(thecode=="PHP"){
//playSound("test2.mp3");
alert('Checked value is: '+thecode+'.');
}else{
//playSound("test3.mp3");
alert('Checked value is: nothing');
}
}
}
</script>

<label for="code1"><input type="radio" value="HTML" name="code" id="code1"> HTML</label>
<br><label for="code2"><input type="radio" value="PHP" name="code" id="code2"> PHP</label>
<br><label for="code3"><input type="radio" value="MySQL" name="code" id="code3"> MySQL</label>
<br><input type="button" onclick="getchecked()" value="Show Checked Value">

thanks!
