JavaScript - Get Date Function Trouble
Hi all,
Basically I'm having trouble writing a date function to return this data: [CODE] // Get Date d=new Date(); a=d.getUTCFullYear(); b=d.getUTCMonth() + 1; c=d.getUTCDate(); e=d.getUTCHours() - 1; f=d.getUTCMinutes(); [CODE] I need it so I can run setinterval on the date function. I'm quite new to javascript (obviously!) so any help will be much appreciated. Thanks Similar TutorialsSomeone tell me where I'm going wrong. I'm trying to print out the month/year ? Code: <html><head>
<SCRIPT language=JavaScript>
var dateNow = new Date();
var monthNow = dateNow.getMonth();
var yearNow = dateNow.getYear();
function MakeArray(n) {
this.length = n
return this
}
monthNames = new MakeArray(12)
monthNames[1] = "Janurary"
monthNames[2] = "February"
monthNames[3] = "March"
monthNames[4] = "April"
monthNames[5] = "May"
monthNames[6] = "June"
monthNames[7] = "July"
monthNames[8] = "August"
monthNames[9] = "Sept."
monthNames[10] = "Oct."
monthNames[11] = "Nov."
monthNames[12] = "Dec."
function customDate(oneDate) {
var theMonth = monthNames[oneDate.getMonth() +1]
}
</SCRIPT>
</head><body><script type="text/javascript">
document.write(theMonth + "/" + yearNow);
</script>
</body></html>
Hi I'm having trouble with the pickString function bellow the getRandomNumber function. When working it should be invoked using the variable "termString" (bellow) as the argument. I hope someone can help as i can't move on without this section working. Thanks <SCRIPT language="JavaScript"> //TO DO: PASTE THE getRandomNumber() FUNCTION YOU WROTE FOR TASK 1 HERE function getRandomNumber(aNumber) { var rand = Math.floor(Math.random() * aNumber + 1); return (rand); } //Task 2 (iii)(a) /* Picks a random substring from a string separated by delimiter characters.

UGH! What am I doing wrong? the error points to the this in the function. Is it that IE doesn't like map? Has anyone seen this before? I thought my code was correct. Works perfect in FF, chrome and opera. the canvas text doesn't work in opera, but it does render the features so the each function is working. I'll post the code if needed, but it's huge. here's the script running. http://www.pdxbusiness.com/canvas/golf/ I am taking an online class and the instructor is no help whatsoever. Please see where I'm going wrong with this. I'm sure it is something small I'm missing. Thanks. The assignment is: Create a function named emLink() that writes an email address using text strings of the username and server names entered in reverse order as parameter values. The command to call the function would look as follows: emLink("eman","revres"). Call the stringReverse() function with name as the parameter value to reverse the order of characters. Code:
<html>
<head>
<script type="text/javascript">
function emLink(name,server) {
var rname="eman";
var rserver="revres";
stringReverse(rname);
stringReverse(rserver);
var email="eman@revres";
var mailText='<a href="mailto:eman@revres">"eman@revres"</a>';
document.write(mailText);
}
function stringReverse(textString) {
if (!textString) return '';
var revString='';
for (i = textString.length-1; i>=0; i--)
revString+=textString.charAt(i)
return revString;
}
</script>
</head>
<body>
<script type="text/javascript">
var rname="reldac";
var rserver="ude.ortsa.uwm";
emLink(rname,rserver);
</script>
</body>
</html>
Currently, all it returns it : "eman@revres" I am trying to create a simple auto-calculate function for a webpage. What should be happening: The 'onchange' command should pass the 'price' of the item to the function, the function should then cycle through all the dropdowns (or checkboxes or fields) and calculate the total. What is happening: It is only picking up the last checkbox. It seems that the 'for' loop only remembers the last item in the array. What am I doing wrong? How can I get the code to remember all the items? thanks, Code: <script language="JavaScript" type="text/javascript">
function calculateTotal(price)
{
var total = 0;
var cList = ['sel1','sel2','sel3'];
for (i=0;i<2;i++);
var select = GetE(cList[i]); total+= price * (select.options[select.selectedIndex].value);
GetE("totalShow").innerHTML = total.toFixed(2);
}
function GetE(id) {return document.getElementById(id); }
</script>
<html>
<head></head><body>
<form id="form1" name="form1" method="post" action="">
<select name="sel1" id="sel1" onchange="calculateTotal(100)">
<option value="0">0</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select><br><br>
<select name="sel2" id="sel2" onchange="calculateTotal(200)">
<option value="0">0</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select><br><br>
<select name="sel3" id="sel3" onchange="calculateTotal(300)">

I'm trying to verify todays date against my input date, using a check value function, but for some reason when it comes to a day over 9 like 12/10/2009 or 12/20/2009 looks like is only recognizing the first number 12/1/2009 and 12/2/2009 and getting my alert back as to choose a future date, this is my code, any help would be greatly appreciated: var currentTime = new Date() var month = currentTime.getMonth() + 1 var day = currentTime.getDate() var year = currentTime.getFullYear() function checkValues() { if (owt8.dayr.value <=month+'/'+day+'/'+year ) { alert("Please enter a future date!"); return false; } owt8.submit(); alert("Your request has been submited") window.close() } I am trying to create a function that takes a users input in the form xx/xx/xxxx. Then I need to figure out a way to compare to a new date and give which day of the year it is when using: alert("This is the" +foo+ "day of the year."). Im alittle confused on how to take the users input and compare it somehow to give me the day of the year.
I am working on an HTML project that displays a field with a number in the field by each day. What it does is start at 0 on day one. Each day it adds a 1 to the field. Day 2, the field would say 1, then day 3 would say 2, and so on. I am not sure how to approach this. This is also displayed in an HTML format. I want to to be automatic and change as the date changes. I will also need a way to reset it back to zero if possible.
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? So I want this function to return the date in the format: 4-Jan-2011. I feel like I have to make the variables strings or something but I can't figure it out, I'm kinda new to javascript. Code: function calander(TheDay) {
var theDate = new Date();
var day = new theDate.getDay();
var month = new theDate.getMonth();
var year = new theDate.getFullYear();
if (month == 0) {month = "Jan";}if (month == 1) { month = "Feb"; }
if (month == 2) { month = "March"; }if (month == 3) { month = "April"; }
if (month == 4) { month = "May"; }if (month == 5) { month = "June"; }
if (month == 6) { month = "July"; }if (month == 7) { month = "Aug"; }
if (month == 8) { month = "Sept"; }if (month == 9) { month = "Oct"; }
if (month == 10) { month = "Nov"; }if (month == 11) { month = "Dec"; }
TheDay.value = day + "-" + month + "-" + year;
}
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. 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? 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!");
}
