I am trying to create a calendar in JavaScript and I am trying to disable the previous day from today.
for (var c = 0; c < 42 - r; c++) {
var v = e[c].day;
var m = g(new Date(t, n - 1, v))
? `<div id="${v}/${n}/${t}" class="today" type="button" onclick="addRow(this)">`
: z(new Date(t, n - 1, v))
? `<div class="past">`
: `<div id="${v}/${n}/${t}" type="button" onclick="addRow(this)">`;
l.append(
m +
"" +
'<span class="month">' +
i[n - 1] +
"</span>" +
"" +
v +
"</div>"
);
}
So here v is a day, n is a month and t is a year. And here is g and z functions:
function g(e) {
return y(new Date()) == y(e);
}
function z(e) {
return y(new Date()) > y(e);
}
function y(e) {
return e.getFullYear() + "/" + (e.getMonth() + 1) + "/" + e.getDate();
}
So I am expection to have previous dates like this: <div class="past">, today is like this: <div id="${v}/${n}/${t}" class="today" type="button" onclick="addRow(this)"> and future is like this: <div id="${v}/${n}/${t}" type="button" onclick="addRow(this)">
But what I am having is <div class="past">, <div id="${v}/${n}/${t}" class="today" type="button" onclick="addRow(this)">, <div class="past">
So where do you think I am making things wrong?
The problem is that "2021/8/9" is greater than "2021/8/10" when you do string comparison (9 is greater than 1). You need those month/day values properly zero padded (2021/08/09) vs (2021/08/10).
Try
function y(e) {
return e.getFullYear()
+ "/" + String(e.getMonth() + 1).padStart(2, "0")
+ "/" + String(e.getDate()).padStart(2, "0");
}

I'm using the following jQuery date range picker library : http://longbill.github.io/jquery-date-range-picker/
I would like to remove / hide all Sundays from all date range pickers while keeping a normal behavior on the date range pickers.
I tried to do something with beforeShowDay option :
beforeShowDay: function(t) {
var valid = t.getDay() !== 0; //disable sunday
var _class = '';
// var _tooltip = valid ? '' : 'weekends are disabled';
return [valid, _class];
}
but it only "disables" all Sundays whereas I want to remove / hide them:
Here's the fiddle I'm working on : https://jsfiddle.net/maximelafarie/dnbd01do/11/
EDIT:
Updated fiddle with #Swanand code: https://jsfiddle.net/maximelafarie/dnbd01do/18/
You could do it with just a little CSS but it does leave a gap:
.week-name th:nth-child(7),
.month1 tbody tr td:nth-child(7) {
display: none;
}
Hope this helps a little.
You need do changes in two functions in your daterangepicker.js file:
createMonthHTML()
function createMonthHTML(d) { var days = [];
d.setDate(1);
var lastMonth = new Date(d.getTime() - 86400000);
var now = new Date();
var dayOfWeek = d.getDay();
if ((dayOfWeek === 0) && (opt.startOfWeek === 'monday')) {
// add one week
dayOfWeek = 7;
}
var today, valid;
if (dayOfWeek > 0) {
for (var i = dayOfWeek; i > 0; i--) {
var day = new Date(d.getTime() - 86400000 * i);
valid = isValidTime(day.getTime());
if (opt.startDate && compare_day(day, opt.startDate) < 0) valid = false;
if (opt.endDate && compare_day(day, opt.endDate) > 0) valid = false;
days.push({
date: day,
type: 'lastMonth',
day: day.getDate(),
time: day.getTime(),
valid: valid
});
}
}
var toMonth = d.getMonth();
for (var i = 0; i < 40; i++) {
today = moment(d).add(i, 'days').toDate();
valid = isValidTime(today.getTime());
if (opt.startDate && compare_day(today, opt.startDate) < 0) valid = false;
if (opt.endDate && compare_day(today, opt.endDate) > 0) valid = false;
days.push({
date: today,
type: today.getMonth() == toMonth ? 'toMonth' : 'nextMonth',
day: today.getDate(),
time: today.getTime(),
valid: valid
});
}
var html = [];
for (var week = 0; week < 6; week++) {
if (days[week * 7].type == 'nextMonth') break;
html.push('<tr>');
for (var day = 0; day < 7; day++) {
var _day = (opt.startOfWeek == 'monday') ? day + 1 : day;
today = days[week * 7 + _day];
var highlightToday = moment(today.time).format('L') == moment(now).format('L');
today.extraClass = '';
today.tooltip = '';
if (today.valid && opt.beforeShowDay && typeof opt.beforeShowDay == 'function') {
var _r = opt.beforeShowDay(moment(today.time).toDate());
today.valid = _r[0];
today.extraClass = _r[1] || '';
today.tooltip = _r[2] || '';
if (today.tooltip !== '') today.extraClass += ' has-tooltip ';
}
var todayDivAttr = {
time: today.time,
'data-tooltip': today.tooltip,
'class': 'day ' + today.type + ' ' + today.extraClass + ' ' + (today.valid ? 'valid' : 'invalid') + ' ' + (highlightToday ? 'real-today' : '')
};
if (day === 0 && opt.showWeekNumbers) {
html.push('<td><div class="week-number" data-start-time="' + today.time + '">' + opt.getWeekNumber(today.date) + '</div></td>');
}
if(day == 0){
html.push('<td class="hideSunday"' + attributesCallbacks({}, opt.dayTdAttrs, today) + '><div ' + attributesCallbacks(todayDivAttr, opt.dayDivAttrs, today) + '>' + showDayHTML(today.time, today.day) + '</div></td>');
}else{
html.push('<td ' + attributesCallbacks({}, opt.dayTdAttrs, today) + '><div ' + attributesCallbacks(todayDivAttr, opt.dayDivAttrs, today) + '>' + showDayHTML(today.time, today.day) + '</div></td>');
}
}
html.push('</tr>');
}
return html.join('');
}
In this function i have added class hideSunday while pushing the element.
The 2nd function is getWeekHead():
function getWeekHead() {
var prepend = opt.showWeekNumbers ? '<th>' + translate('week-number') + '</th>' : '';
if (opt.startOfWeek == 'monday') {
return prepend + '<th>' + translate('week-1') + '</th>' +
'<th>' + translate('week-2') + '</th>' +
'<th>' + translate('week-3') + '</th>' +
'<th>' + translate('week-4') + '</th>' +
'<th>' + translate('week-5') + '</th>' +
'<th>' + translate('week-6') + '</th>' +
'<th class="hideSunday">' + translate('week-7') + '</th>';
} else {
return prepend + '<th class="hideSunday">' + translate('week-7') + '</th>' +
'<th>' + translate('week-1') + '</th>' +
'<th>' + translate('week-2') + '</th>' +
'<th>' + translate('week-3') + '</th>' +
'<th>' + translate('week-4') + '</th>' +
'<th>' + translate('week-5') + '</th>' +
'<th>' + translate('week-6') + '</th>';
}
}
In this file, I have added class to week-7 header.
CSS:
.hideSunday{display:none;}
Please note, I have not checked all the scenario but it will do trick for you.
I finally ended up by letting the Sundays appear (but completely disabling them).
These questions inspired me :
Moment.js - Get all mondays between a date range
Moment.js: Date between dates
So I created a function as follows which returns an array that contains the "sundays" (or whatever day you provide as dayNumber parameter) in the date range you selected:
function getDayInRange(dayNumber, startDate, endDate, inclusiveNextDay) {
var start = moment(startDate),
end = moment(endDate),
arr = [];
// Get "next" given day where 1 is monday and 7 is sunday
let tmp = start.clone().day(dayNumber);
if (!!inclusiveNextDay && tmp.isAfter(start, 'd')) {
arr.push(tmp.format('YYYY-MM-DD'));
}
while (tmp.isBefore(end)) {
tmp.add(7, 'days');
arr.push(tmp.format('YYYY-MM-DD'));
}
// If last day matches the given dayNumber, add it.
if (end.isoWeekday() === dayNumber) {
arr.push(end.format('YYYY-MM-DD'));
}
return arr;
}
Then I call this function in my code like that:
$('#daterange-2')
.dateRangePicker(configObject2)
.bind('datepicker-change', function(event, obj) {
var sundays = getDayInRange(7, moment(obj.date1), moment(obj.date1).add(selectedDatesCount, 'd'));
console.log(sundays);
$('#daterange-2')
.data('dateRangePicker')
.setDateRange(obj.value, moment(obj.date1)
.add(selectedDatesCount + sundays.length, 'd')
.format('YYYY-MM-DD'), true);
});
This way, I retrieve the amount of sundays in the date range I selected. For example, if there's two sundays in my selection (with sundays.length), I know I have to set two additional workdays to the user selection (in the second date range picker).
Here's the working result:
With the above screenshot, you can see the user selected 4 workdays (5 with sunday but we don't count it). Then he click on the second calendar and the 4 workdays automatically apply.
Here's the result if the period apply over a sunday (we add one supplementary day and Xfor X sundays in the period):
Finally, here's the working fiddle: https://jsfiddle.net/maximelafarie/dnbd01do/21/
I want to thank any person that helped me. The question was hard to explain and to understand.
You can also do it by setting a custom css class and use it in beforeShowDay like below
.hideSunDay{
display:none;
}
beforeShowDay: function(t) {
var valid = t.getDay() !== 0; //disable sunday
var _class = t.getDay() !== 0 ? '' : 'hideSunDay';
// var _tooltip = valid ? '' : 'weekends are disabled';
return [valid, _class];
}
But it only hides the sundays beginning from current day.
Here is a working fiddle
https://jsfiddle.net/dnbd01do/16/
getDateRange = function () {
date = new Date();
var test;
selectedOption = $('#daterange').change().val()
console.log(selectedOption) // reusult 0
switch (selectedOption) {
case 0:
test = '/' + date.getFullYear() + '-' + 0 + date.getMonth() + '-' + date.getDate() + '/' + date.getFullYear() + '-' + 0 + (date.getMonth() + 1) + '-' + date.getDate()
break
}
return test
}
console.log($('#daterange').change().val()) // result 0
console.log(getDateRange()) // result "undefined". Why?
Why is the result of the switch statement always undefined?
Change your case statement to case '0' since val() returns a string.
Also: If you are not doing any other things after your switch statement except returning your test variable, you could also just return your value and get rid of var test.
getDateRange = function() {
date = new Date();
selectedOption = $('#daterange').change().val();
switch (selectedOption) {
case '0':
return '/' + date.getFullYear() + '-' + 0 + date.getMonth() + '-' + date.getDate() + '/' + date.getFullYear() + '-' + 0 + (date.getMonth() + 1) + '-' + date.getDate();
}
}
console.log(getDateRange());
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" id="daterange" value="0" />
$('#daterange').change().val() returns a string, but in switch you compare with a number.
Also, in the current example, you don't need switch, because you have only one case:
getDateRange = function () {
var selectedOption = $('#daterange').change().val();
if (selectedOption === '0') {
return ...
}
}
I javascript your dataType should be tighly match with your comparision operatot, so compare it with ===
In this case type and data both will match together.
getDateRange = function() {
date = new Date();
selectedOption = $('#daterange').change().val();
switch (selectedOption) {
case '0':
return '/' + date.getFullYear() + '-' + 0 + date.getMonth() + '-' + date.getDate() + '/' + date.getFullYear() + '-' + 0 + (date.getMonth() + 1) + '-' + date.getDate();
}
}
console.log(getDateRange());
I have a script that prints the current date and time in JavaScript, but when it prints time, it's missing one 0. Here is the code:
var currentdate = new Date();
var datetime = "0" + currentdate.getDate() + ".0"
+ (currentdate.getMonth()+1) + "."
+ currentdate.getFullYear() + " "
+ currentdate.getHours() + ":"
+ currentdate.getMinutes();
document.write(datetime);
It should print 04.03.2016 15:04 and prints 04.03.2016 15:4.
Two digit minutes print fine.
Any leads?
Try this
var formatDateDigit = function (i) {
return i <= 9 ? ("0" + i) : i;
};
var currentdate = new Date();
var datetime = formatDateDigit(currentdate.getDate()) + "."
+ formatDateDigit(currentdate.getMonth()+1) + "."
+ currentdate.getFullYear() + " "
+ formatDateDigit(currentdate.getHours()) + ":"
+ formatDateDigit(currentdate.getMinutes());
document.getElementById('my_output_here').innerHTML = datetime;
<div id="my_output_here"></div>
I have tried many ways to make a live clock (with seconds) appear in a rendered table but it's not working propperly. The clock stays static, not showing second by second. I'm doing the following :
function myTable(){
var table = $('<table></table>');
table.append($('<tr>')
.append($('<td>')
.addClass('col2 data')
.attr('rowspan', '2')
.append($('<span>')
.attr('id', 'date_time')
)
)
)
$("#myDiv").html(table)
}
liveClock();
var liveClock = function () {
date = new Date;
//some logic here to generate the data I need the result above ( no problems here )
result = '' + d + '/' + month + '/' + year + ' ' + h + ':' + m + ':' + s;
var setDateTime = function() {
$("#date_time").html(result);
return false;
};
var everySec = setInterval(setDateTime, 1000);
}
Your problem is that you're never updating result, so each time your code fires SetDateTime, it renders the same date in the table. Move these lines:
date = new Date;
//some logic here to generate the data I need the result above ( no problems here )
result = '' + d + '/' + month + '/' + year + ' ' + h + ':' + m + ':' + s;
Into your setDateTime function.
i'm trying to use the gethours() method in javascript but it keeps returning military time. can someone please help me out fixing it so that it displays clock time? (1-12). Thank you so much!
// Reroute from the conf.js script
var chat = $( '.chat-output' ),
message = function ( message, userId ) {
var dt = new Date(),
time = dt.getHours() + ":" + dt.getMinutes(); // + ":" + dt.getSeconds();
return $( '<div class="chat-message color-' + users[userId] + '">' +
'<div class="chat-id color-' + users[userId] + '"></div>' +
'<div class="chat-user-message">' + message + '</div>' +

function ampm(date){
var dt= date || new Date,
h= dt.getHours(),
m= dt.getMinutes(),
s= dt.getSeconds(),
ampm;
if(h>12){
h-= 12;
ampm= (h%12)? ' PM': ' AM';
}
else ampm= (h%12)? ' AM': ' PM';
m= m<10? '0'+m: m;
s= s<10? '0'+s: s;
return [h, m, s].join(':')+ampm;
}
ampm()
/* returned value: (String)
11:52:55 PM
*/
Something like this?
var dt = new Date();
var hours = dt.getHours();
var ampm = hours > 11 ? 'PM' : 'AM';
if (hours > 12) {
hours -= 12;
} else if (hours === 0) {
hours = 12;
}
var time = hours + ":" + dt.getMinutes() + ' ' + ampm;
Fiddle
Here's another version of formatting a time in 12 hour format:
// Returns formatted time for given Date object, or
// current system time if d is falsey.
function getTime(d) {
d = d || new Date();
var hrs = d.getHours();
var pad = function(n){return (n<10?'0':'')+ +n};
return pad(hrs%12 || 12) + ':' + pad(d.getMinutes()) + ' ' + (hrs<12? 'AM':'PM');
}
console.log(getTime(new Date(2014,2,24, 0, 5))); // 12:05 AM
console.log(getTime(new Date(2014,2,24,10,25))); // 10:25 AM
console.log(getTime(new Date(2014,2,24,20,15))); // 08:15 PM
Note that 24hr time is preferred in many cases to avoid anomalies like 12:00 AM (which is really neither AM or PM) and 12:00 AM being before 01:00 AM.
