Getting ArgumentNullException: Value cannot be null when using DateTimePicker

Before I use it DateTimePicker everything was working fine, but after adding some javascript code for datetimepicker I am getting ArgumentNullException for
#Html.DropDownListFor(x => x.LeagueId, new SelectList(ViewBag.Leagues, "Id", "LeagueType"), "", new { #class = "form-control", id="liga" }), first player is added successfully but when I want to one more, my application crashes.
Input for date
<div class="form-group">
<label asp-for="Player.Birth" class="control-label">#DbResHtml.T("Датум на раѓање","Resources")</label>
<input asp-for="Player.Birth" type="text" class="form-control datepicker" required id="birth" />
<span asp-validation-for="Player.Birth" class="text-danger"></span>
</div>
After adding this lines of code my app crashes
<script>
$(document).ready(function() {
$.datetimepicker.setDateFormatter('moment');
$(".datepicker").datetimepicker({
timepicker: false,
format: 'DD/MM/YYYY',
});
})

I called startLoading before everything and it still doesn't work
I removed async: false but, I need to wait for the data to be returned from the API

In this When click on Select all checkbox then all values from should
be checked but when select all checked box is checked then only value
from current pagination got selected.
table contain is generated from ajax to avoid loss of checked value
while page load.

In your case
$(".checkBoxClass").prop('checked', true);
should work too.
The .prop() method gets the property value for only the first element in the matched set. It returns undefined for the value of a property that has not been set, or if the matched set has no elements.
Read More: Here

In jquery you can achieve this by:
$('input[type="checkbox"]').prop('checked', true);
It will make all checkbox checked.

Weird JS Behavior With Bootstrap Sliders

So I recieved help from an internet saint to vastly improve my code to create a bootstrap slider per list item within a JS for loop, but now it is behaving erratically.
Sometimes it works perfectly, others it creates new items but not sliders (just a text input field), and others it only creates one item per list.
Any great minds see where I'm going wrong?
var proArray = [];
function addPro() {
var val = document.getElementById("proInput").value.trim();
document.getElementById("proForm").reset();
if (val.length == 0) {
return;
}
if (document.getElementById('proInput' + val) == null) {
proArray.push({id: val, slider: null});
} else {
return;
}
for (var i = 0; i < proArray.length; i++) {
var ele = document.getElementById('proInput' + proArray[i].id);
if (ele == null) {
var newItem = "<li><p>" + proArray[i].id + "</p><input class='bootstrap-slider' type='text' value='' id='proInput" +
proArray[i].id + "' data-slider-id='SIDproInput" + proArray[i].id
+ "' data-slider-min='0' data-slider-max='10' data-slider-value='5'/></li>";
document.getElementById("proList").innerHTML += newItem;
proArray[i].slider = new Slider('#proInput' + proArray[i].id, {
formatter: function(value) {
return 'Current value: ' + value;
}
});
} else {
(function(i) {
setTimeout(function() {
var val = proArray[i].slider.getValue();
proArray[i].slider.destroy();
document.getElementById('SIDproInput' + proArray[i].id).remove();
proArray[i].slider = new Slider('#proInput' + proArray[i].id, {
formatter: function (value) {
return 'Current value: ' + value;
}
});
proArray[i].slider.setValue(val);
}, 100);
})(i);
}
}
}
var conArray = [];
function addCon() {
var valCon = document.getElementById("conInput").value.trim();
document.getElementById("conForm").reset();
if (valCon.length == 0) {
return;
}
if (document.getElementById('conInput' + valCon) == null) {
conArray.push({id: valCon, slider: null});
} else {
return;
}
for (var i = 0; i < conArray.length; i++) {
var ele = document.getElementById('conInput' + conArray[i].id);
if (ele == null) {

Because you have two lists you can use two arrays:
var proArray = [];
var conArray = [];
The inline functions can be changed in order to pass the list prefix as parameter:
newAdd('pro')
newAdd('con')
And so you can adjust the addPro function to these changes.
From comment:
If I type in "#" or "?" as an item in your snippet above it shows the error. Not for you?
In order to solve such an issue you need to escape those chars when creating the slider:
arr[i].slider = new Slider('#' + listIdPrefix + 'Input' +
arr[i].id.replace(/#/g, '\\#').replace(/\?/g, '\\?').....
The snippet:
var proArray = [];
var conArray = [];
function newAdd(listIdPrefix) {
var val = document.getElementById(listIdPrefix + "Input").value.trim();
document.getElementById(listIdPrefix + "Form").reset();
if (val.length == 0) {
return;
}
var arr;
if (document.getElementById(listIdPrefix + 'Input' + val) == null) {
if (listIdPrefix == 'pro') {
proArray.push({id: val, slider: null});
arr = proArray;
} else {
conArray.push({id: val, slider: null});
arr = conArray;
}
} else {
return;
}
for (var i = 0; i < arr.length; i++) {
var ele = document.getElementById(listIdPrefix + 'Input' + arr[i].id);
if (ele == null) {
var newItem = "<li><p>" + arr[i].id + "</p><input class='bootstrap-slider' type='text' value='' id='" + listIdPrefix + "Input" +
arr[i].id + "' data-slider-id='SID" + listIdPrefix + "Input" + arr[i].id
+ "' data-slider-min='0' data-slider-max='10' data-slider-value='5'/></li>";
document.getElementById(listIdPrefix + "List").innerHTML += newItem;
arr[i].slider = new Slider('#' + listIdPrefix + 'Input' + arr[i].id.replace(/#/g, '\\#').replace(/\?/g, '\\?').replace(/\./g, '\\.'), {
formatter: function (value) {

} else {
(function (i, arr) {
setTimeout(function () {

arr[i].slider.destroy();

Getting JSON Object then adding parts to HTML

I have been trying to get a script to work for my Github site and I am processing a JSON file to get an array to HTML in a ordered list.
My code I have been using is:
$(document).ready(function() {
$.getJSON("https://raw.githubusercontent.com/vvoid-inc/LillyPak-Starbound/gh-pages/mods/stable.json", function(data) {
$.each(mods, function(i) {
var tempUrl = "";
var tempApproved = "";
if (data.mods[i].Repo[0] == 0) {
tempUrl = data.mods[i].Repo[1];
} else if (data.mods[i].Repo[0] == 1) {
tempUrl = "http://community.playstarbound.com/resources/" + data.mods[i].Repo[1] + "/";
} else {
tempUrl = data.mods[i].Repo[1];
}
if (data.mods[i].Approved == true) {
tempApproved = "checked";
} else {
tempApproved = "";
}
$("#modsList").append("<li><a href='" + tempUrl + "'>" + data.mods[i].Title + "</a> - by " + data.mods[i].Author + "<ul><li>\t- <input type='checkbox' " + tempApproved + "/> Approved</li></ul></li>");
});
console.log(data);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<ol id="modsList"></ol>
So what have I been doing wrong because nothing is working...

This should work:
$(document).ready(function() {
$.getJSON("https://raw.githubusercontent.com/vvoid-inc/LillyPak-Starbound/gh-pages/mods/stable.json", function(data) {
$.each(data.mods, function(i, m) {
var tempUrl = "";
var tempApproved = "";
if (m.Repo[0] == 0) {
tempUrl = m.Repo[1];
} else if (m.Repo[0] == 1) {
tempUrl = "http://community.playstarbound.com/resources/" + m.Repo[1] + "/";
} else {
tempUrl = m.Repo[1];
}
if (m.Approved == true) {
tempApproved = "checked";
} else {
tempApproved = "";
}
$("#modsList").append("<li><a href='" + tempUrl + "'>" + m.Title + "</a> - by " + m.Author + "<ul style='list-style-type:none'><li>\t - <input type='checkbox' " + tempApproved + " disabled/> Approved</li></ul></li>");
});
console.log(data);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<ol id="modsList"></ol>
Instead of $.each(mods, function(i) { it should be $.each(data.mods, function(i, m) {. and the mods[i]. should be m..
Also there was a formatting error in the JSON file but now it is fixed. It was causing the errors to not display.
