JavaScript - Javascript Date Math - Date In Past Plus 14 Days?
Not sure if this is possible in javascript:
I'm looking for two different dates (bill date and due date) on an invoice that are captured by OCR. If one of them exists, but the other does not, I want the empty field to be 14 days before (or after) the other. For example: if the bill date is 7/27/2010 and the due date was not captured, I want to set the due date as 8/10/2010 (14 days after the bill date). If the due date was captured as 8/10/2010, but the due date is blank, I want to assign the bill date as 7/27/2010 (14 days before the due date). if both dates have values, do nothing. Thanks. Similar TutorialsHi, I need to add days to a date in javascript, My requirement is as follows: Date is coming from a textbox. eg:- 26/07/2010 days from this statement var day1=document.getElementById('<%=HiddenDate.ClientID %>').value; an eg:- if the date is 28/01/2012 and days Needed to be added=5 the added date should be 02/02/2012. Can anybody help me? Thanks Jamuna hi, anyone knows how to get the past 6th month date using time difference? like if the current date is given 18-April-2011 then the past 6th month date is 18-October-2010...how can this be done by using time difference? Thanks, verve I can't wrap my head around this at the moment so with the hope of finding someone willing to take a stab I am posting this to all of you. I need to create a savings ticker that shows $ saved per second. The data is as follows then = date script is created now = current date std = savings to date in $ avg = average savings per second in $ It would need to calculate the difference in time between then and now, convert that to an integer that can then be multiplied by avg then std would be added. thanks in advance I'm just trying to add X days to a given date object. However, it's not the right answer (did it in PHP to check, and my PHP version works). dateObj = new Date (month + '/' + day + '/' + year); // Grab the object for a given date datestamp = dateObj.getTime(); // Get millisecond timestamp newDate = new Date (datestamp + (1000 * 60 * 60 * 24 * parseInt (daysToAdd))); // Add "daysToAdd" days to the date alert (newDate); It's not daysToAdd days away... Any help is greatly appreciated. I wrote a version not using the Date () object, but rather an array of the days in each month, and then subtracting each month until "day" was below 31, etc. It's a lot less efficient than this method though :P I am trying to figure out how to calculate the date 30 days ago. I also will need to be able to change the interval. Anyone have a piece of code that does this? Hello, I have a textbox with a date formatted 'dd/mm/yyyy'. I want to be able to add days to the date so that the month ticks over if the days exceed the days in the month and the year also if the month value passes 12. Currently I have the below. This adds to the days but will not tick over the month. Any help please. Thanks Code: <html>
<head>
<script type="text/javascript">
function calDate() {
var dateArr = document.getElementById('testinput').value;
var myDate = new Date();
var day;
var month;
var year;
day = dateArr.substring(0,2);
month = dateArr.substring(3,5);
year = dateArr.substring(6,10);
if (day.charAt(0) == '0')
{
day = day.charAt(1);
}
if (month.charAt(0) == '0')
{
month = month.charAt(1);
}
myDate.setDate(day);
myDate.setMonth(month); // January = 0
myDate.setFullYear(year);
alert((myDate.getDate()+28)+ "/" + (myDate.getMonth()) + "/" + myDate.getFullYear());

I've written a js function to find the difference between two dates. the format being used is dd/mm/yyyy hh:mm. The function returns correct value when give one set of values, but go wrong with another set. examples are given below. set 1 : Time 1 = 24/02/2011 09:30 , time 2 = 24/02/2011 16:00 Output is corret here. It gives 6 Hours & 30 Minutes (after converting the difference) set 2: Time 1 = 24/02/2011 09:30 , time 2 = 25/02/2011 16:00 Here, it gives 31 days, 6 Hours & 30 Minutes. My code is given below. Also the alert of dates display strange values. Don't know if it is timezone issue. I wonder what is going wrong here Code: function compareDateTime(frmtime,totime)
{
var date1 = new Date(frmtime);
var date2 = new Date(totime);
var diff = new Date();
alert(date1);
alert(date2);
diff = (date2.getTime()-date1.getTime());
if (diff<0)
{
alert("From Time cannot be later than To Time!");
return 0;
}
else if (diff==0)
{
alert("From Time cannot be equal with To Time!");
return 0;
}
else
{
return diff;
}
}
The returned diff value is broken down as following: Code: if (diff>0)
{
days = Math.floor(diff / (1000 * 60 * 60 * 24));
diff -= days * (1000 * 60 * 60 * 24);
hours = Math.floor(diff / (1000 * 60 * 60));
diff -= hours * (1000 * 60 * 60);
mins = Math.floor(diff / (1000 * 60));
alert(days+","+hours+","+mins);
return true;
}
what am i doing wrong here? Hi folks, i am trying to generate a dynamic datefield with date mask "mm/dd/yyyy" and trying to insert it into Oracle db ...i still got the error ORA invalid month ehich means the date filed is not recognized as date: below is what i am doing : newStartDate = document.createElement( 'INPUT' ); newStartDate.setAttribute('type','Date'); newStartDate.setAttribute('id1','id'+ elementid+elementrow); newStartDate.setAttribute('name','StartDateName'+ elementid+elementrow); newStartDate.size=8; newStartDate.style.backgroundColor= bgc; any help thanks ?? Also i want to add a datepicke to this textbox..how it is posible / other option is to use Jquery datepicker but could not know how to impement it thanks again I have a drop down menu where people can select a month, day and year. Based on their selection, I want to show them an image. If their selection is >= July 26, 2010 but <= July 25, 2011, show the red image; If their selection is >= July 26, 2011 but <= July 25, 2012, show the white image; If their selection is >= July 26, 2012 but <= July 25, 2013, show the blue image; If their selection is >= July 26, 2013 but <= July 25, 2014, show the yellow image; I don't know how to compare a selected date to a range of dates like this. Using Adobe Form Javascript validation, how would I do this code for Visual Basic in Javascript (non web) Code: If PurchaseDate.Value > Date Then
MsgBox ("PurchaseDate cannot be greater than Today's Date!")
Cancel = True
End If
Something along these lines but this isnt working: Code: If (PurchaseDate.Value > Date) Then
{
app.alert ("Purchase Date cannot be greater than Today's Date!");
}
Thanks Hello, I really need your help with one. How can I use the following code below to save the date from my popup window datepicker back into a var and relay it back onto its parent page? I can't seem to figure this out: Code: <html>
<head>
<script>
function open_cal() {
var str_html = ""
+ "<!DOCTYPE html>\n"
+ "<html lang=\"en\">\n"
+ "<head>\n"
+ "<meta charset=\"utf-8\">\n"
+ "<title>CALENDAR</title>\n"
+ "<link href=\"jq/jquery-ui.css\" rel=\"stylesheet\" type=\"text/css\">\n"

var j = window.open("","CALENDAR","width=200,height=250,status=no,resizable=yes,top=200,left=200")
j.opener = self;
j.document.write(str_html);
}
</script>
</head>
<body>
<input onclick="open_cal()" type="button" value="Open" name="B1">

</html>
Datepicker.js: Code: $(function() {
$( "#datepicker" ).datepicker({
dateFormat: 'dd/mm/yy',
onSelect: function(dateText, inst) {
alert(dateText)
window.close()
}
})
});
Any help with this is greatly and mostly appreciated. Thanks in advance, Cheers, J Hi, I've inherited a Form which calculates a future date based on a calculation and then inserts today's date and the future date into a database. The day part of the date is formatted as a number. This is fine, but up to 9 the numbers display in single figures with no leading zeros. I want them to display leading zeros (e.g. 01, 02, 03, 04, 05, 06, 07, 08, 09, 10, 11... 30, 31) So; 1/12/2010 is NOT wanted 01/12/2010 IS wanted The inherited code originally set the Month names as "Jan", "Feb" etc, and it was easy to kludge these to 01, 02... 12, but I suspect there's a more elgant solution to this as well, this bit of the code works so it's not as vital to neaten this but my database needs dd/mm/yyyy format (it's a third party email program). Code: </script>
<script type="text/javascript">
var todaysDate = new Date();
function updateExpiryDate(){
var weeklyMileage = document.getElementById('AvWeeklyMileage').value;
var expiryDate;
var weeks = 0;
var expiryDateString = '';
if (!isNaN(parseInt(weeklyMileage))){
weeks = 700/weeklyMileage;
expiryDate = new Date(todaysDate.getTime() + (1000 * 3600 * 24 * 7 * weeks));
var expiryDateString = expiryDate.getDate() + '/' + getMonthString(expiryDate.getMonth()+1) + '/' + expiryDate.getFullYear();
document.getElementById('expiryDate').innerHTML = expiryDateString;
document.getElementById('ShoeExpiryDate').value = expiryDateString;
} else {
document.getElementById('ShoeExpiryDate').value = '';
document.getElementById('expiryDate').innerHTML = 'Please enter a valid weekly average mileage'
}
}
function getMonthString(monthNumber){
var monthString = "";
switch(monthNumber){
case 1:
monthString = "01";
break;
case 2:
monthString = "02";
break;
case 3:
monthString = "03";
break;
case 4:
monthString = "04";
break;
case 5:
monthString = "05";
break;
case 6:
monthString = "06";
break;
case 7:
monthString = "07";
break;
case 8:
monthString = "08";
break;
case 9:
monthString = "09";
break;
case 10:
monthString = "10";
break;
case 11:
monthString = "11";
break;
case 12:
monthString = "12";
break;
default:
// do nothing;
}
return monthString;
}
function setTodaysDate(){
var todaysDateString = todaysDate.getDate() + '/' + getMonthString(todaysDate.getMonth()+1) + '/' + todaysDate.getFullYear();
document.getElementById('todaysDate').innerHTML =todaysDateString;
document.getElementById('DateOfPurchase').value = todaysDateString;
}
Can someone point me in the right direction please? hello there this is in vb script. but i dont where to post it. can any one hlep me out plzz I need to check if the date entered by user is within 5th date from current date. I am trying to do it this way entered date has month and date value Code: sResvDate = 01/24 Set sMaxDays to getdate(5) but get date will give year too. and how do i compare if it less than 5th day or not. how can I get 1 tenth of a second for my clock? (bad typo for clock. I had to edit it. I'm saying that for the admin because I know you're not suppose to edit excessively)
hello i have this code: Code: Code: function buildMonthlyEntries() {
var startDate = new Date(document.getElementById('startDate').value);
var endDate = new Date(document.getElementById('endDate').value);
if(startDate == "Invalid Date" || endDate == "Invalid Date") { return null; }
var entryCount = endDate.getMonth() - startDate.getMonth();
var monthlyEntries = document.getElementById('monthlyEntries');
monthlyEntries.innerHTML = "";
for(var i = 0; i < entryCount; i++) {
var textElement = document.createElement('input');
textElement.setAttribute('type', 'text');
textElement.setAttribute('id', 'entry' + i);
monthlyEntries.appendChild(textElement);
}
return null;
}
<div id="dateRange">
<input type="text" id="startDate">
<input type="text" id="endDate">
</div>
<div id="monthlyEntries"></div>
<INPUT TYPE="button" NAME="button" Value="Click" onClick="buildMonthlyEntries()">
It calculates the number of months between the 2 dates and generates the number of input filds equal to the number of months. The only problem is when i change the year. For example if i have start date 2012-03-22 and enddate 2013-04-22, instead of generating 13 input fields it only generates 1 field, because it only substracts months. How can i make this script also calculate corectly months even if year is changed? Thanks Hello. I have got this kind of array: Code: $days = array('Monday' => '2012-03-19',
'Tuesday' => '2012-03-20'
);
I'm iterating like this: Code: foreach($days as $key => $value){
echo '<a href="javascipt:confirmDelete('.$value.');">Delete</a>';
}
Script: Code: function confirmDelete(day)
{
if (confirm('Delete?')) {
window.location.href = 'processDay.php?action=delete&day=' + day ;
}
}
While i hover over the link with coursor, it show it good: javascript:confirmDelete(2012-03-19), but when I submit the delete confirmation, i get &day=1987. Where is the problem? |
