I'm working on a spring mvc project, and I want to submit the date to the server. Changing form:submit is not working. So How can I do it?? Let the object be 'Permissions' (class components are given to you). Please help.

Modifying JS code to remove DatePicker option

I'm trying to add a datepicker to a page I'm creating. Since I don't know much at all about Javascript I'm modifying an example I've found at https://code-boxx.com/simple-datepicker-pure-javascript-css/. I don't want any extra pages or files as I need the form I'm creating to be entirely self-contained. I've condensed it down to this:
<!DOCTYPE html>

visibility: hidden;

}
.picker-wrap.show {
opacity: 1;
visibility: visible;
}
.picker-wrap .picker {
margin: 50vh auto 0 auto;
transform: translateY(-50%);
}
/* (B) CONTAINER */
.picker {
max-width: 300px;

/* (C) MONTH + YEAR */
.picker-m, .picker-y {

Since I don't want the inline date picker and only want the pop-up date picker, I thought all I would need to do is remove this section:
<!-- (B1) INLINE DATE PICKER -->
<input type="text" id="input-inline" placeholder="Inline"/>
<div id="pick-inline"></div>
but when I do that the pop-up stops working as well. What do I need to change to remove the inline but just keep the pop-up?

You commented the template code for the inline date picker, but you have not commented the script for inline date picker.
Comment out the below code to make your solution working.
// Comment this code block in script
picker.attach({
target: "input-inline",
container: "pick-inline",
});
Why this was throwing error?
The datepicker was trying to find a target from dom having id input-inline. Since you have commented it out, it will not be available. Thats why it was stoping the execution of javascript. The code got broken there and the lines below that is not executed. This is why your popup date picker was also not working.

How to show Open/Closed based on two shift working hours on website

I'm trying to display Open or Closed based on a shift (two Shifts daily) using Javascript. I want to be able to use that data which is stored within a span and then determine if the business is open or closed and display that. for me only one shift is working during second shift its displaying We are now closed.
Might be something better to do the same but only in HTML.
any other suggestion is appreciated.
Here is the code I have so far:
function isOpen(timeRangeEl, date) {
var day = '' + date.getDay();
var hhmm = ('0' + date.getHours()).slice(-2) + ':' + ('0' + date.getMinutes()).slice(-2);
var days = timeRangeEl.getAttribute('data-days');
var openTime = timeRangeEl.getAttribute('data-open');
var closeTime = timeRangeEl.getAttribute('data-close');
return days.indexOf(day) >= 0 && openTime <= hhmm && hhmm < closeTime;
}
function openClose() {
var date = new Date();
var display = document.getElementById('open-display');
var els = display.getElementsByClassName('timerange');
var anyActive = false;
for (var i = 0; i < els.length; i++) {
if (isOpen(els[i], date)) {
anyActive = true;
els[i].className = els[i].className.replace(/ *inactive\b/g, '');
} else if (els[i].className.indexOf('inactive') < 0) {
els[i].className += ' inactive';
}
}
if (anyActive) {
display.className = 'open';
} else {
display.className = 'closed';
}
}
setInterval(openClose, 5000);
openClose();
#open-display.open > .timerange.inactive,
#open-display.open > .timerange2.inactive,
#open-display.open .days {
display: none;
}
#open-display.open > .openclosed::before {
content: 'We are now Open';
}
#open-display.closed > .openclosed::before {
content: 'We are now Closed';
}
<div class="text">
<h3>Working Hours</h3>

Javascript app freezing after approximately two hours (memory leak?)

I'm currently developing a home automation user interface, running on a wall-mounted android (version 4.2.2) tablet, which, after a couple of minutes of inactivity, displays a "screensaver" html page.
As you can see in the screenshot above, this "screensaver" basically consists of the following features :
a clock displaying the current time and date, triggered by the script date_time.js and refreshed at one second interval;
a picture on the top right-hand side which shows the current status of the alarm;
a picture "Touchez l'écran pour quitter le mode veille" which is randomly repositioned every 3500 miliseconds.
Both points 2) and 3) above are run by another script stored in a script called "screensaver_run.js". The method getAlarmDataFromDatabase is retrieving data from my mysql database.
Now, for the problem statement: after approximately two hours, the whole screen freezes (both the clock and the repositioning script) in such a way that even the tablet is no longer pingable. I suspect that a memory leak is occurring but after a couple of sleepless nights ... and a lot of coffee ... I am not able to find out the root cause of my issue.
Reading some documentation on the internet, notably https://www.lambdatest.com/blog/eradicating-memory-leaks-in-javascript, I have already implemented some changes such as changing the declaration of the variables from "var" to "let".
In Chrome, I run the script during 2 1/2 minutes and profiled the memory usage (I have the heaptimeline file available, if it can be of any help, but here I'm not quite sure how to analyse it?):
Besides, I queried the console for :
performance.memory.usedJSHeapSize and got some changing values :
3430886, 3195206, 4743246, 3402767, etc
performance.memory.jsHeapSizeLimit and got : 4294705152
Does anyone have any hint where to start investigating, knowing that debugging possibilities of this tablet are not as advanced as on a modern browser? My tablet is "already" 5 years old... Upgrading this tablet is not an option.
Many thanks for your time reading me and I do hope that my post is understandable, well documented and in the future, could help other to have restful nights :)

Ajax Request Not Always Consistent

I have been developing a site that will provide schedules created by people. I'm using Alienware to develop it and the ajax code works perfectly on the laptop all of the time. I am using IE. However, if I access my site on my Samsung Smart TV or my HTC U11 phone, Ajax isn't consistent. It displays the data I am requesting, however, when I sum up a total of hours for the week, it sometimes displays the correct hours, or sometimes shows 0 hours, when the user is scheduled for the week. Why is it inconsistent between devices? I know that Ajax is recommended for IE. As I said, though, it sometimes will display the correct total weekly hours, and other times it will just show zero. This issue isn't occurring on my Alienware.
I've already tried using onload instead of onreadystatechange. I've set the request to asynchronous and synchronous. Whether it's set to true or false, on my other devices, it fails to be consistent. I've tried it as a post and get method, and both also are inconsistent. What is wrong with my code?

I expect every device to be consistent with the hour total it should be displaying, on every device that Ajax should work on.

Javascript Booking Year Calendar

I'm looking for year calendar with select range functions, but i don't found this. And I decided customize Bootstrap Year Calendar - http://www.bootstrap-year-calendar.com/
And I'm stuck, my customised version is on http://ngrdanjski.com/calendar/
and I'm looking for help!
I added:
All days are disabled by default.
You can added Price periods, in this dates period you have enabled booking.
I want to add option when first click on the day it's first day of booking range, and second click is last day of booking range. Right now when click on day you have enable start date/first day, but when you click second time on day when you want to select end date, it's again start/first date. I wan't to have function to select start and end date. First click on day is start and second is end.
Code for current behavior is:
if(this.options.enableRangeSelection) {
cells.mousedown(function (e) {
if(e.which == 1)
{
var currentDate = _this._getDate($(this));
//console.log(currentDate);
if(_this.options.allowOverlap || _this.getEvents(currentDate).length == 0)
{
_this._mouseDown = true;
_this._rangeStart = _this._rangeEnd = currentDate;
_this._refreshRange();
}
}
});
cells.mouseenter(function (e) {
//console.log(e);
if (_this._mouseDown)
{
var currentDate = _this._getDate($(this));
if(!_this.options.allowOverlap)
{
var newDate = new Date(_this._rangeStart.getTime());
if(newDate < currentDate)
{
var nextDate = new Date(newDate.getFullYear(), newDate.getMonth(), newDate.getDate() + 1);
while(newDate < currentDate)
{
if(_this.getEvents(nextDate).length > 0)
{
break;
}
newDate.setDate(newDate.getDate() + 1);
nextDate.setDate(nextDate.getDate() + 1);
}
}
else
{
var nextDate = new Date(newDate.getFullYear(), newDate.getMonth(), newDate.getDate() - 1);
while(newDate > currentDate)
{
if(_this.getEvents(nextDate).length > 0)
{
break;
}
newDate.setDate(newDate.getDate() - 1);
nextDate.setDate(nextDate.getDate() - 1);
}
}
currentDate = newDate;
}
var oldValue = _this._rangeEnd;
_this._rangeEnd = currentDate;
if (oldValue.getTime() != _this._rangeEnd.getTime())
{
_this._refreshRange();
}
}
});
/* $(window).mouseup(function (e) {
if (_this._mouseDown)
{
_this._mouseDown = false;
_this._refreshRange();
var minDate = _this._rangeStart < _this._rangeEnd ? _this._rangeStart : _this._rangeEnd;
var maxDate = _this._rangeEnd > _this._rangeStart ? _this._rangeEnd : _this._rangeStart;
_this._triggerEvent('selectRange', {
startDate: minDate,
endDate: maxDate,
events: _this.getEventsOnRange(minDate, new Date(maxDate.getFullYear(), maxDate.getMonth(), maxDate.getDate() + 1))
});
}
}); */

I don't have skill for this functionality, please help.
Tnx!

I edited your code a bit. I understand that you want to set two dates, the start and the end of the range, and all that happens in two clicks. I also added a check if the second date is after the first one, if it's not they will swap places, so the earlier date is the rangeStart. The dates are stored in rangeStart and rangeEnd:
Edit: here's a pen
cells.mousedown(function (e) {
if(e.which == 1)
{
var currentDate = _this._getDate($(this));
//console.log(currentDate);
if(_this.options.allowOverlap || _this.getEvents(currentDate).length == 0)
{
if(!_this._mouseDown) {
_this._mouseDown = true;
_this._rangeStart = _this._rangeEnd = currentDate;
_this._refreshRange();
}
else {
_this._mouseDown = false;
_this._rangeEnd = currentDate;
if(_this._rangeEnd.getTime() < _this._rangeStart.getTime()) {
var tempDate = _this._rangeEnd;
_this._rangeEnd = _this._rangeStart;
_this._rangeStart = tempDate;
}
// _this._refreshRange();
}
}
if(_this._rangeStart != _this._rangeEnd) {
console.log(_this._rangeStart.getDate() + ',' + _this._rangeEnd.getDate());
}
}
});
