JavaScript - How To Return Date With Leading Zero's
I have the following which returns the date in the format I need it in but it does not have the leading zero's
Code: var wholeDate = getTheDay();
function getTheDay(){
var d = new Date();
var year = d.getFullYear();
var numMonth = d.getMonth() + 1;
var day = d.getDate();
var whole = year + '-' + numMonth + '-' + day;
alert(whole);
return whole;
}
Would return todays date as 2012-1-5 How do I get the date returned like 2012-01-05 ? Similar TutorialsHi All, how do I trim leading zero in a date e.g 08/08/2003 to become 8/8/2003. thanks I don't understand the logic of Break, Return False, Return True. It was never really covered in our college class, and I see everyone using it. I got an A in the class, if that 'proves' that I really tried to apply myself. NOTE: I understand what the function is doing. I just don't understand WHEN to use break, return false or return true if the the translator can determine the conditional statements. PHP Code: function submitForm(){ var ageSelected = false; for (var i=0; i<5; ++1){ if (document.forms[0].ageGroup[i].checked == true) { ageSelected = true; break; } } if (ageSelected == false){ window.alert("You must select your age group"); return false; } else return false; } if the the translator can determine the conditional statements, why not write it like this: PHP Code: function submitForm(){ var ageSelected = false; for (var i=0; i<5; ++1){ if (document.forms[0].ageGroup[i].checked == true) { ageSelected = true; break; // what's the point for the 'break'? Won't the rest of the code be ignored since it passed the first condition? } } if (ageSelected == false){ window.alert("You must select your age group"); return false; } // why not leave the last else out? is it just a 'safety' catch, in case something other than true or false is inputted? else return false; // what's the point? } Questions: Why use return true, if the translator knows it's ture? Why use "return false" if the translator knows it's false and the alert window has already gone up? why not use "break" to stop the code? Why use the "return false" at the end "else" statement? Hi room, Hey, I opened up the source code for this page in google chrome and since i'm learning javascript, i wanted see if i could "read" it and figure out what was going on. I'm am having the hardest time understanding "return false" and "return true". Could someone step me through this via interpreting this code (in bold typeface): Code: var DefaultValue = 'Search';
function clearSearch() {
if (document.searchForm.q.value == DefaultValue) {
document.searchForm.q.value = '';
}
}
function validateSearchHeader() {
if ( document.searchForm.q.value == '' || document.searchForm.q.value.toLocaleLowerCase() == DefaultValue.toLocaleLowerCase() ) {
alert('Please enter at least one keyword in the Search box.');
document.searchForm.q.focus();
return false;
}
return true;
}
Thanks! Hello all is it possible to strip leading (meaning at the VERY begining of the text) and trailing (anything at the end of the text) carriage returns with reg ex? so if smbody enters return return return start txt entry ----> keep all other returns in paragraph sloppy ending retrun return return it would remove the start and end returns I'd like to add it to this if possible. Code: comts = comts.replace(/^\s+|\s+$/g,""); // strip leading and trailing spaces low tech (validation script done trying to improve on it now) 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;
}

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!");
}

I can figure out the rest i need from that . Thanks, Tom i achieved to make a chain: Code: function getId(id) {
id_elem = document.getElementById(id);
return {
color:function(e){
id_elem.style.color = e;
}
};
}
so this can be getId("test").color("red"); but what happens if i want to do that? Code: function getId(id) {
id_elem = document.getElementById(id);
return id_elem;
return { ????......
how can i chain if i use return in the first place? |
