time diffrence in double digit

i want to display TravelTimeHoursDiff and TravelTimeMinutesDiff in double digit now my time is shown as 7:0 i want to display like 07:00
if ($scope.DispatchStatus.ArrivalTime != undefined){
var today = $rootScope.getSysDate().split(" ");
var timeArrival = new Date(today[0] + ' ' + $scope.DispatchStatus.ArrivalTime);
var TravelTime = new Date(today[0] + ' ' + $scope.Route.TravelTime);
var timeArrivalHours = timeArrival.getHours();
var TravelTimeHoursDiff = timeArrivalHours - TravelTime.getHours() ;
var TravelTimeMinutesDiff = (timeArrival.getMinutes() - TravelTime.getMinutes());
if(TravelTimeHoursDiff < 0 || (TravelTimeHoursDiff <= 0 && TravelTimeMinutesDiff < 0) || (TravelTimeHoursDiff == 0 && TravelTimeMinutesDiff == 0)){
$scope.formvalidationbit = $scope.DispatchStatusAddForm[fieldName].$invalid = true;
angular.element('#' + fieldName).addClass('ng-invalid');
angular.element('#' + fieldName).removeClass('ng-valid');
$scope.DispatchStatusAddForm.$valid = false;
var errorbit = 1;
}else{
if (isNaN(TravelTimeHoursDiff)) {
TravelTimeHoursDiff = '--';
}
if (isNaN(TravelTimeMinutesDiff)) {
TravelTimeMinutesDiff = '--';
}
if(TravelTimeMinutesDiff <0){
TravelTimeMinutesDiff = TravelTimeMinutesDiff * (-1);
}
$scope.TravelTime = TravelTimeHoursDiff + ':' + TravelTimeMinutesDiff;
}
}

Just add leading 0 to values smaller then 10, something like:
let addLeadingZero(v){
return v < 10 ? ("0" + v) : v;
}
$scope.TravelTime = addLeadingZero(TravelTimeHoursDiff) + ':' + addLeadingZero(TravelTimeMinutesDiff);

JS AM/PM times always show AM

I am making a simple time calculator in javascript. I have converted the times into 12-hour instead of 24 hour time for simplicity, however the code I have for calculating am/pm always shows am. Any reason why this would be happening?
Here is my code:
function solveTime(x) {
var suffixSolve = (utcHours + x) % 24;
var suffix = "am";
if (utcHours > 12) {
var suffix = "pm";
}
if (utcMinutes == 0) {
utcMinutesLead = "00";
}
if (utcMinutes < 10) {
utcMinutesLead = "0" + utcMinutes;
}
var timeSolve = (((utcHours + x) + 11) % 12 + 1);
var timeTotal = timeSolve + ":" + utcMinutesLead + " " + suffix;
var utcMod = x;
if (utcMod > 0) {
utcMod = "+" + utcMod;
}
document.getElementById(x).innerHTML = "(UTC" + utcMod + ") " + timeTotal;
}
and here is the code behind utcHours
var masterTimeUTC = new Date();
var utcHours = masterTimeUTC.getUTCHours();
var utcMinutes = masterTimeUTC.getUTCMinutes();
var utcSeconds = masterTimeUTC.getUTCSeconds();
var utcMinutesLead = masterTimeUTC.getUTCMinutes();
Example here: http://codepen.io/markgamb/pen/gwGkbo

The issue is you should be checking whether suffixSolve is greater than 12 instead of utcHours, because utcHours does not change due to the value of x. Since you can shift the hours forward and backwards, I created a variable shift to handle that.
function solveTime(x) {
if (x < 0) {
var shift = 24 + x;
} else {
var shift = x;
}
var suffixSolve = (utcHours + shift) % 24;
var suffix = "am";
if (suffixSolve > 12) {
suffix = "pm";
}
if (utcMinutes == 0) {
utcMinutesLead = "00";
}
if (utcMinutes < 10) {
utcMinutesLead = "0" + utcMinutes;
}
var timeSolve = (((utcHours + x) + 11) % 12 + 1);
var timeTotal = timeSolve + ":" + utcMinutesLead + " " + suffix;
var utcMod = x;
if (utcMod > 0) {
utcMod = "+" + utcMod;
}
document.getElementById(x).innerHTML = "(UTC" + utcMod + ") " + timeTotal;
}
var masterTimeUTC = new Date();
var utcHours = masterTimeUTC.getUTCHours();
var utcMinutes = masterTimeUTC.getUTCMinutes();
var utcSeconds = masterTimeUTC.getUTCSeconds();
var utcMinutesLead = masterTimeUTC.getUTCMinutes();
solveTime(4);
solveTime(0);
solveTime(-8);

Sum of value in label having same class

I am trying to add all values of class tmpcpa and place result in final_cpa but final_cpa always return 0.
document.getElementById('cpa' + arr[0]).innerHTML = cpa + '(' + '<label id="tmpcpa">' + tmp_cpa + "</label>" +' For Final' + ')';
var final_cpa = calculate_final_cpa();
console.log(final_cpa);
function calculate_final_cpa() {
var final_cpa = 0;
$('.tmpcpa').each(function () {
if ($(this).val() != 0)
final_cpa += parseInt($(this).text()) || 0;
});
return final_cpa;
}
Surprisingly when i view source code in browser HTML appears as
<label class="tmpcpa">0</label> but when i do inspect element it shows as
<label class="tmpcpa">30.0</label>
Update here is the whole JS. HTML calls process function which ultimately calls calculate_final_cpa()
//"use strict";
function process(arr) {
document.getElementById('txtgrade' + arr[0] + arr[1] + arr[2]).innerHTML = show_grade(document.getElementById('txtpercentage' + arr[0] + arr[1] + arr[2]).value);

you need to be sure you are calling the function after the document is ready.
Also, you are using unassigned value.

Transform HH MM SS in seconds

I need to transform 3 form inputs (HH, MM, SS) in seconds with javascript.
I have this code but it has only with 1 form input in seconds : https://jsfiddle.net/94150148/hhomeLc3/
To do this I need a new javascript function.
window.onload = function () {generate()};
function generate() {
var width = 'width=\"' + document.getElementById('width').value + '\" ';
var height = 'height=\"' + document.getElementById('height').value + '\" ';
var ytid = "videoID";
var start = document.getElementById('start').value;
var end = document.getElementById('end').value;
if (start !== "") {
if(ytid === document.getElementById('ytid')) {
ytid += '?start=' + start;
}
else {
ytid += '&start=' + start;
}
}
if (end !== "") {
if (ytid === document.getElementById('ytid')) {
ytid += '?end=' + end;
}
else {
ytid += '&end=' + end;
}
}
document.getElementById('embedcode').value = '<iframe ' + width + height +
'src=\"https://www.youtube.com\/embed\/' + ytid +
'\" frameborder=\"0\"><\/iframe>';
}
function clearall() {
document.getElementById('width').value = 550;
document.getElementById('height').value = 315;
document.getElementById('start').value = "";
document.getElementById('end').value = "";
}
The jsFiddle to play with what I need : https://jsfiddle.net/94150148/ybmkcyyu/

https://jsfiddle.net/ybmkcyyu/3/
EDIT:
Do not display start and end when value is 0
https://jsfiddle.net/ybmkcyyu/6/
EDIT2:
https://jsfiddle.net/ybmkcyyu/7/
if (start !== "") {
ytid += '?start=' + start;
}
if (end !== "") {
if (start == "") {
ytid += '?end=' + end;
}
else {
ytid += '&end=' + end;
}
}
You just need to get value of every fields, as int, then add it with the formula: ((hours * 60) + minutes ) * 60 + secondes
And you might ensure that the result is a number. (if user enter a char instead of a number, it should not display something wrong)
var starth = parseInt(document.getElementById('starth').value);
var startm = parseInt(document.getElementById('startm').value);
var starts = parseInt(document.getElementById('starts').value);
var endh = parseInt(document.getElementById('endh').value);
var endm = parseInt(document.getElementById('endm').value);
var ends = parseInt(document.getElementById('ends').value);
var start = (((starth * 60) + startm) * 60) + starts;
if(isNaN(start) || start === 0)
start = "";
var end = (((endh * 60) + endm) * 60) + ends;
if(isNaN(end) || end === 0)
end = "";
/* (...) */

JS is generally quite good at math.
sHour = document.getElementById('starth').value,
sMin = document.getElementById('startm').value,
sSec = document.getElementById('starts').value,
sTime = (sHour * 3600) + (sMin * 60) + sSec;

Unexpected end of input JavaScript

Can somebody please tell me what is wrong with the JavaScript in this code? It said "Unexpected end of input", but I do not see any errors. All my statements seem to be ended at some point, and every syntax checker says that no errors were detected.

You've gotten the punctuation wrong in more than one of your onclick attributes, for instance here:
$("#sls").append('<button onclick = "loadSlide\'1\')" id = "slide_1">Slide 1</button>');
It's missing the opening parenthesis. The reason syntax checks don't immediately catch this is because you're putting code inside a string. Which you should not do.
Since you're using jQuery, how about using .click(function() { ... }) instead of inline attributes? Just be careful to get your captured variables correct.

The problem at line 63
$("#sl").append('button onclick = "newSlide()">New Slide</button>');
Should be:
$("#sl").append('<button onclick = "newSlide()">New Slide</button>');
