Basically I'm trying to create a validator for birthdays using the last information (mm/dd) but it is not returning the value as expected
var today = new Date();
var dd = String(today.getDate()).padStart(2, '0');
var mm = String(today.getMonth() + 1).padStart(2, '0');
today = mm + '/' + dd;
var newday = today.toString();
var birthday = "1992/09/21";
var monthday = birthday.substr(birthday.length - 5);
function validator(newday, birthday) {
if (monthday === newday) {
console.log('True');
return true;
}
else {
console.log('False');
return false
}
}
validator();
console.log(newday, monthday)
Can you try this
var today = new Date();
var dd = String(today.getDate()).padStart(2, '0');
var mm = String(today.getMonth() + 1).padStart(2, '0');
today = mm + '/' + dd;
var newday = today.toString();
console.log('New Date is', newday)
var birthday = "1992/09/21";
var monthday = birthday.substr(birthday.length - 5);
console.log('Month day', monthday)
function validator(newday, birthday) {
if (newday === birthday) {
console.log('True');
return true;
}
else {
console.log('False');
return false
}
}
validator(newday, monthday);
//console.log(newday, monthday)
momentjs is a light weight javascript library, used for
validating, manipulating and formatting date.
It provide wrappers to get month, year and date.
var date = new Date();
//Get todays Day and month in "DD/MM" format
var newday = moment(date, 'YYYY/DD/MM').format('DD/MM');
console.log("newDay: " + newday);
//Get birthdate Day and month in "DD/MM" format
var birthday = moment("1992/09/21", 'YYYY/MM/DD').format('DD/MM');
console.log("birthday: " + birthday);
function validator(newday, birthday) {
if (newday === birthday) {
console.log('True');
return true;
}
else {
console.log('False');
return false
}
}
validator(newday, birthday);

I am having a problem with my JQuery code, after swal alert, it doesn't append value to the inputs.
What I do first I check if the value of the start_date is Empty if yes then swal alert, then when I select it the values won't append to the boxes...
function ChangeDate() {
debugger;
var Startdate = document.getElementById("lease_stattdate").value;
var thisDate = new Date(Startdate);
var month = thisDate.getMonth();
var year = thisDate.getFullYear();
var dateSelected = thisDate.getUTCDate();
var firstDay = 1;
var LastDate = new Date(year, month + 1, 0);
var LastDay = LastDate.getDate();
var today = new Date();
var TodayMonth = today.getMonth();
var date = true;
if (month <= TodayMonth) {
jQuery.noConflict();
swal("Error!", "Please select upcoming month!", "warning");
$('#lease_stattdate').val('');
$('#renewal_notice').val('');
$('#end_date').val('');
$('#termination_notice').val('');
window.location.reload();
}
if (month > TodayMonth && dateSelected > firstDay) {
jQuery.noConflict();
swal("Error!", "Please select first day of the month!", "warning");
$('#lease_stattdate').val('');
$('#renewal_notice').val('');
$('#end_date').val('');
$('#termination_notice').val('');
window.location.reload();
}
if (month > TodayMonth && dateSelected == firstDay) {
var tempday = 15;
var nextdate = new Date(year, month + 23, tempday);
var NXmonth = nextdate.getMonth();
var NXyear = nextdate.getFullYear();
var terminateday = new Date(NXyear, NXmonth + 1, 0).getDate();
var exitdate = new Date(NXyear, NXmonth, terminateday).toLocaleDateString('en-ZA');
var renewalNotice = new Date(NXyear, NXmonth-2, 1).toLocaleDateString('en-ZA');
var terminationNotice = new Date(NXyear, NXmonth, 1).toLocaleDateString('en-ZA');
$('#renewal_notice').val(renewalNotice);
$('#end_date').val(exitdate);
$('#termination_notice').val(terminationNotice);
}
}
There is a variable which contains event time. I want to redirect user if event time + 04:38 is more than current time.
Below is the code i have tried:
var deadline = getDayInstance("Monday","08:00:59")
function getDayInstance(day,time) {
const days = {"Sunday":0,"Monday":1,"Tuesday":2,"Wednesday":3,"Thursday":4,"Friday":5,"Saturday":6};
if(days[day]!==undefined)
var dayINeed = days[day];
else
var dayINeed = 2; // for Tuesday
const today = moment().tz("America/Los_Angeles").isoWeekday();
var dt;
// if we haven't yet passed the day of the week that I need:
if (today <= dayINeed) {
dt = moment().tz("America/Los_Angeles").isoWeekday(dayINeed).format('YYYY-MM-DD')+"T"+time;
}
else {
dt = moment().tz("America/Los_Angeles").add(1, 'weeks').isoWeekday(dayINeed).format('YYYY-MM-DD')+"T"+time;
}
console.log("Event Time: "+dt);
var maxLimit = Date.parse(moment(time,'HH:mm:ss').tz("America/Los_Angeles").add({"hours":4,"minutes":43,"seconds":33}).format("YYYY-MM-DDTHH:mm:ss"));
var now = Date.parse(moment().tz("America/Los_Angeles").format('YYYY-MM-DDTHH:mm:ss'));
if(maxLimit < now)
{
dt = moment().tz("America/Los_Angeles").add(1, 'weeks').isoWeekday(dayINeed).format('YYYY-MM-DD')+"T"+time;
window.setVideo = false;
}
console.log(moment(time,'HH:mm:ss').tz("America/Los_Angeles").add({"hours":4,"minutes":43,"seconds":33}).format("YYYY-MM-DDTHH:mm:ss"));
console.log(moment().tz("America/Los_Angeles").format('YYYY-MM-DDTHH:mm:ss'));
return dt;
}
var maxLimit = Date.parse(moment(deadline,'YYYY-MM-DDTHH:mm:ss').add({"hours":4,"minutes":43,"seconds":33}).format("YYYY-MM-DDTHH:mm:ss"));
var now = Date.parse(moment().tz("America/Los_Angeles").format('YYYY-MM-DDTHH:mm:ss'));
if(maxLimit>=now){
var redirectTo = $("#lp-pom-button-673").attr('href');
if(redirectTo.length > 3){
window.location.href = redirectTo;
}
else{
window.location.href = "https://******/";
}
}
I need to maintain timezone in calculation.
I got the answer of this after refining the process theoretically and then try to implement it in JS. Below is the new code that can be used for this.
var deadline = getDayInstance("Tuesday", "02:32:00");
var maxLimit,now;
function getDayInstance(day,time) {
const days = {"Sunday":0,"Monday":1,"Tuesday":2,"Wednesday":3,"Thursday":4,
"Friday":5,"Saturday":6};
if(days[day]!==undefined)
var dayINeed = days[day];
else
var dayINeed = 2; // for Tuesday
const today = moment().tz("America/Los_Angeles").isoWeekday();
var dt;
// if we haven't yet passed the day of the week that I need:
if (today <= dayINeed) {
dt = moment().tz("America/Los_Angeles").isoWeekday(dayINeed)
.format('YYYY-MM-DD')+"T"+time;
}
else {
dt = moment().tz("America/Los_Angeles").add(1, 'weeks')
.isoWeekday(dayINeed).format('YYYY-MM-DD')+"T"+time;
}
var d = new Date(dt);
d.setHours(d.getHours() + 4);
d.setMinutes(d.getMinutes() + 43);
d.setSeconds(d.getSeconds() + 32);
max = Date.parse(d);
now = Date.parse(moment().tz("America/Los_Angeles").format('YYYY-MM-DDTHH:mm:ss'));
if(maxLimit < now)
{
dt = moment().tz("America/Los_Angeles").add(1, 'weeks')
.isoWeekday(dayINeed).format('YYYY-MM-DD')+"T"+time;
}
return dt;
}
if(maxLimit>=now){
var redirectTo = $("#lp-pom-button-673").attr('href');
if(redirectTo.length > 3){
window.location.href = redirectTo;
}
else{
window.location.href = "https://******/";
}
}
I using a date-picker to set a start and end date. The date range is supposed to move forward each day for a two week, sliding window of entry.
My code below works but I would like to refactor it into something that is easier to maintain. What techniques or tools can I use to improve this code?
var challenge_start = new Date(2015,04,04);
var challenge_end = new Date(2015,06,12);
var range_start;
var range_end;
var today = new Date();
var dd = today.getDate();
var mm = today.getMonth()+1; //January is 0!
var yyyy = today.getFullYear();
if(today<challenge_start) {
range_start=challenge_start;
range_end=challenge_start;
}
else if(today>challenge_start && today<challenge_end) {
if(mm==5) {
if(dd<18) {
range_start=challenge_start;
range_end=today;
}
else {
range_start=today.setDate(today.getDate()-14);
range_end=today;
}
}
else if(mm=6) {
if(dd<29) {
range_start=today.setDate(today.getDate()-14);
range_end=today;
}
else {
range_start=today.setDate(today.getDate()-14);
range_end=challenge_end;
}
}
else if(mm==7) {
if(dd<12) {
range_start=today.setDate(today.getDate()-14);
range_end=challenge_end;
}
else {
range_start=challenge_end;
range_end=challenge_end;
}
}
}
else if(today>challenge_end) {
range_start=challenge_end;
range_end=challenge_end;
}
$("#date").datepicker({
startDate: range_start,
endDate: range_end,
keyboardNavigation: false,
autoclose: true,
todayHighlight: true,
language: langdate,
disableTouchKeyboard: true
});
I may not understand what you are striving for, but I'm pretty sure you don't need to have those if(mm==x) and if(dd=x) statements.
Perhaps this is what you want:
var challenge_start = new Date(2015,04,04);
var challenge_end = new Date(2015,06,12);
function getDatePlusDays(origDate, days) {
var date = new Date(origDate.getTime());
date.setDate(date.getDate() + days);
return date;
}
function getClosestDateInRange(startDate, endDate, date) {
return (date < startDate) ? startDate
: ((date > endDate) ? endDate: date);
}
var today = new Date();
var range_start = getClosestDateInRange(challenge_start, challenge_end, getDatePlusDays(today, -14));
var range_end = getClosestDateInRange(challenge_start, challenge_end, today);

It would appear from the source code of Calendar that you need to pass the desired date into the Calendar() constructor as the second argument to the constructor. See lines 16 and 588 for details.
I have this code that updates a calendar widget and input field, while validating the date. We want the user to be able to input any type of m-d-y format (m.d.y, m-d-y, and so on). The problem is the YUI calendar widget only accepts the m/d/y format. All others it returns as NaN. I have tried a couple ways to format the date, but can't get anything that seems to work. I would like to be able to do this with out a lot of overblown code. Does anyone have any suggestions as to the best approach here? Here is my code:
//CALENDAR --------------------------------------------------------------------------------
var initCal = function(calendarContainer){
if(YAHOO.env.getVersion("calendar")){
var txtDate = Dom.get("dateOfLoss");
var myDate = new Date();
var day = myDate.getDate();
var month = myDate.getMonth() +1;
var year = myDate.getFullYear() -1;
var newDate = month + "/" + day + "/" + year;
function handleSelect(type, args, obj){
var dates = args[0];
var date = dates[0];
var year = date[0], month = date[1], day = date[2];
txtDate.value = month + "/" + day + "/" + year;
aCal.hide();
}
function updateCal(){
if (!(txtDate.value.match(/((\d{2})|(\d))\/|\-((\d{2})|(\d))\/|\-((\d{4})|(\d{2}))/))) {
alert("Enter date in mm/dd/yy or mm/dd/yyyy format.");
}
else {
if (txtDate.value != "") {
aCal.select(txtDate.value);
var selectedDates = aCal.getSelectedDates();
if (selectedDates.length > 0) {
var firstDate = selectedDates[0];
aCal.cfg.setProperty("pagedate", (firstDate.getMonth() + 1) + "/" + firstDate.getFullYear());
aCal.render();
}
else {
alert("Date of Loss must be within the past year.");
}
}
}
}
var aCal = new YAHOO.widget.Calendar(null, calendarContainer, {
mindate: newDate,
maxdate: new Date(),
title: "Select Date",
close: true
});
aCal.selectEvent.subscribe(handleSelect, aCal, true);
aCal.render();
Event.addListener("update", "click", updateCal);
Event.addListener(txtDate, "change", function(e){
updateCal();
});
// Listener to show the 1-up Calendar when the button is clicked
// Hide Calendar if we click anywhere in the document other than the calendar
Event.on(document, "click", function(e){
var el = Event.getTarget(e);
if(Dom.hasClass(el, "calendarButton"))
aCal.show();
else if (Dom.hasClass(el, "link-close") || !Dom.isAncestor(calendarContainer, el))
aCal.hide();
});
}
else {
var successHandler = function() {
initCal(calendarContainer);
};
OURPLACE.loadComponent("calendar", successHandler);
}
};
Did you tried http://www.datejs.com/?
Maybe you can define some patterns and test agaist the input.
How can I convert string to datetime with format specification in JavaScript?
var updateCal = function(){
if (!(txtDate.value.match(/^(0?[1-9]|1[012])[- /.](0?[1-9]|[12][0-9]|3[01])[- /.]\d\d+$/))) {
return;
}
//else if ((txtDate.value.match(/^(0?[1-9]|1[012])[- .](0?[1-9]|[12][0-9]|3[01])[- .]\d\d+$/))) {
//}
else {
var changedDate = txtDate.value;
changedDate = changedDate.replace(/[. -]/g, "/");
txtDate.value = changedDate;
badClaimDate = claimDateWithinPastYear();
aCal.select(changedDate);
I used a RegEx to determine which, if any, delimiters needed to be replaced and simply used .replace.
