minus 7 hours from 'now' date time datepicker entry - javascript

I have 2 datepickers, start and end time.
i want the start time to be minus 7 hours from "now"
i have this:
$('#<%= txtErrorStartDate.ClientID%>').val(formatDateTime(sqlNow('HH', -7), 'dateshorttime')).validate();
and this:
function formatDateTime(d, format, rtnObj) {
var arr
, type
, arrDate
, arrTime
, str
;
if (!d) {
if (rtnObj) {
return null;
} else {
return '';
}
}
switch (format) {

type = 3;
break;

type = 4;
break;

type = 5;
break;
default:
if (rtnObj) {
return null;
} else {
return '';
}
}
if (typeof(d) === 'string') {
if (d.indexOf('/Date(') !== -1) {
// JSON date (milliseconds)
d = new Date(Number(d.replace('/Date(', '').replace(')/', '')));
} else {
str = true;
}
} else if (typeof(d) === 'number') {
d = new Date(d);
}
if (str) {
// Format string
d = $.trim(d);
if (d.indexOf(' ') !== -1) {
// Split date and time
arr = d.split(' ');
arrDate = arr[0].split('/');
arrTime = arr[1].split(':');
if (arrTime.length === 2) {
// Add missing seconds
arrTime.push('00');
}
} else if (d.indexOf('/') !== -1) {
// Split date
arrDate = d.split('/');
arrTime = ['00', '00', '00'];
} else {
arrDate = ['30', '12', '1899'];
arrTime = d.split(':');
if (arrTime.length === 2) {
// Add missing seconds
arrTime.push('00');
}
}
} else {
// Format Javascript date object
// Build date array
arrDate = [];
arrDate.push(d.getDate());
arrDate.push(d.getMonth() + 1);
arrDate.push(d.getFullYear());
// Build time array
arrTime = [];
arrTime.push(d.getHours());
arrTime.push(d.getMinutes());
arrTime.push(d.getSeconds());
// Single digit check
if (Number(arrDate[0]) < 10) { arrDate[0] = '0' + arrDate[0]; }
if (Number(arrDate[1]) < 10) { arrDate[1] = '0' + arrDate[1]; }

}
if (rtnObj) {
// Return Javascript object
// Take 1 from month (0 - 11)
arrDate[1] = String(Number(arrDate[1]) - 1);
switch (type) {
case 1: // shortdate
return new Date(arrDate[2], arrDate[1], arrDate[0]);
break;
case 2: // shorttime
return new Date('1899', '11', '30', arrTime[0], arrTime[1]);
break;
case 3: // dateshorttime
return new Date(arrDate[2], arrDate[1], arrDate[0], arrTime[0], arrTime[1]);

what i have is not working, i would like to know how to subtract 7 hours from the start time
added datepicker html:
<div class="inputrow" runat="server">
<label style="margin-left: 179px" class="inputlabel">Start Date</label>
<input runat="server" type="text" id="txtErrorStartDate" name="txtErrorStartDate1" class="dateshorttime datepick required" value="" data-taborder="1" required="" style="width: 18%" />
</div>

My java knowledge isn't great, but for what its worth, what I would do in C# to accomplish this is:
string startTime = DateTime.Now; // Fire whenever the event starts
string endTime = DateTime.Now; // Fire whenever the event ends
string subtractedTime = currentTime.ToString("HH") - 7; // The time subtracted by 7 hours

var start_time = new Date();
start_time.setHours(start_time.getHours()-7);

i have resolved the issue, with the line of code below.
$('#<%= txtErrorStartDate.ClientID%>').val(formatDateTime(dateAdd('hour', -7, sqlNow()), 'dateshorttime')).validate();
Thank you for your input.

JS template literals: not defined

As I'm writing this function which holds a parameter 'day', I'de like to log the chosen day to the console.
I'm getting the output 'day is not defined' and I cannot figure out why (I'm new to JS).
I believe 'day' is defined because I call the function with an argument.
const getSleepHours = day => {
if (day === 'monday'){
return 8;
} else if (day === 'tuesday'){
return 7;
} else if (day === 'wednesday'){
return 8;
} else if (day === 'thursday'){
return 9;
} else if (day === 'friday'){
return 8;
} else if (day === 'saturday'){
return 9;
} else if (day === 'sunday'){
return 9;
} else {
return 'Please enter a valid day';
}
};
console.log('You have slept for: ' + getSleepHours('sunday') + ' hours');
console.log(`${day}`);
In the function definition syntax, "day" has to be wrapped in paranthesis () as (day). Below is how i would implement it
const getSleepHours = (day) => {
var hours = 0;
switch(day){
case "sunday":
hours=1;
break;
case "monday":
hours=2;
break;
default:
hours=0;
}
return hours;
}
const daysCount = getSleepHours('sunday');
console.log('You have slept for: '+ getSleepHours("sunday") +' hours');
console.log(daysCount);
const getSleepHours = day => { // this day variable will be considered as argument
if (day === 'monday'){
return 8;
} else if (day === 'tuesday'){
return 7;
} else if (day === 'wednesday'){
return 8;
} else if (day === 'thursday'){
return 9;
} else if (day === 'friday'){
return 8;
} else if (day === 'saturday'){
return 9;
} else if (day === 'sunday'){
return 9;
} else {
return 'Please enter a valid day';
}
};
const day = getSleepHours('sunday'); // define day variable so value will be stored which is returned from function.
console.log('You have slept for: ' + getSleepHours('sunday') + ' hours');
console.log(`${day}`);

JS Calculator not working in wordpress, script worked on old site

This issue has been problematic this week. We're creating a new site as the current one is a bit outdated. The current site has a series of financial calculators that work perfectly.
Upon transferring the scripts and content to the new wordpress site, we get an error which prevents it from working.
The error we get is:

I'm sure it's something simple but I've yet to solve it.
At first I thought formc was a typo but it's the exact same on the original site where it works.
You are missing the name attribute on the form.

Equivalent of arrow functions for IE

I wrote a program that works well in Google Chrome, but I just realized that it is having problems in IE. IE states that this is due to a syntax error given by the use of arrow functions since they are not supported in the latest IE. Can anyone tell me how to change my code to be able to run it on IE?

I could be missing something, but after a quick skim of your code, only this line appears to use any ES6 syntax:
.then((value) => {
Simply change it to:
.then(function(value) {
If you have much more code and don't want to remove such references by hand, #jonrsharpe's suggestion of a transpiler is a good one.

Javascript/HTML won't enter switch case other than default

My task was to try and code the game of Pig. I am trying to have the code use a switch statement to determine which chunk of code to follow but it is skipping case 1 and case 2 and going directly to the default case. The roll.score is coming from this Javascript file:
function Dice(d1, d2){ //d1 = die 1 d2 = die 2
this.d1 = d1?d1:parseInt(Math.random()*6 + 1);
this.d2 = d2?d2:parseInt(Math.random()*6 + 1);
}
Dice.prototype.score = function(){ //d1 = die 1 d2 = die 2
if(this.d1 == 1 || this.d2 == 1){
return 1; //return score 0 for turn
}else if(this.d1 == 1 && this.d2 == 1){
return 2; //return 13 as code to reset score to 0
}else
return parseInt(this.d1 + this.d2);
}
Dice.prototype.toString = function(){
return "Rolled " + this.d1 + " and " + this.d2;
}
What it is supposed to do is return either 1, 2, or whatever the 2 number added together are. Like I mentioned above, no matter what the roll.score() returns, the switch statement always goes to the default case.
var again = true;
do {
var roll = new Dice(parseInt(Math.random() * 6 + 1), parseInt(Math.random() * 6 + 1));
window.alert(roll.toString());
turnCounter++;
switch (roll.score) {
case 1: // 1 die = 1
playerScore = roll.score();
again = false;
rollCounter++;
turnCounter++;
document.write("Enters case 1");
break;
case 2: //2 = snake eyes
playerTotal = 0;
playerScore = 0;
again = false;
rollCounter++;
turnCounter++;
break;
default:
playerScore += roll.score();
rollCounter++;
displayScore();
document.write(roll.score() + "<br/>");
var rollAgain = window.prompt("Do you want to roll again?(Y/N)");
if (rollAgain.toUpperCase() === "N") {
again = false;
playerTotal += playerScore;
displayScore();
turnCounter++;
if (playerScore > highScore)
highScore = playerScore;
}
break;
}
rollCounter++;
}while (again);
switch (roll.score) { is not the same as switch (roll.score()) {
roll.score is a function, whereas you want to switch on the result on the returned result (roll.score()).

Convert If-Else statement to Switch Statement

I recently completed a problem in CodeWars using an if-else statement, but I wanted to retry it and use a switch statement instead. Too bad that it is not working the way that I thought it would!
The problem I am solving is to take in a distance(s) that an Ironman triathlon athlete has completed and return an object that shows a key based on whether the athlete should be Swimming, Biking or Running with a value of the length of the race to go.
My If-Else Solution:
function iTri(s) {
var triLength = 140.60;
var result = {};
var str = ' to go!';
var lengthLeft = (triLength - s).toFixed(2);
if (s === 0) {
return 'Starting Line... Good Luck!';
} else if (s <= 2.4) {
result.Swim = lengthLeft + str;
} else if (s <= 114.4) {
result.Bike = lengthLeft + str;
} else if (s < 130.60) {
result.Run = lengthLeft + str;
} else if (s < 140.60) {
result.Run = 'Nearly there!';
} else {
return 'You\'re done! Stop running!';
}
return result;
}
The (non-working) Switch statement:
function iTri(s){
let tri = (2.4 + 112 + 26.2).toFixed(2);
let left = tri - s;
let str = ' to go!'
let result = {};
switch(s) {
case (s === 0):
return "Starting Line... Good Luck!";
break;
case (s <= 2.4):
result.Swim = left + str;
return result;
break;
case (s <= 114.4):
result.Bike = left + str;
return result;
break;
case (s <= 130.60):
result.Run = left + str;
return result;
break;
case (s < 140.60):
result.Run = 'Nearly there!';
return result;
break;
default:
return 'You\'re done! Stop running!';
}
}
These are the tests:
Test.describe("Example tests",_=>{
Test.assertSimilar(iTri(36),{'Bike':'104.60 to go!'});
Test.assertSimilar(iTri(103.5),{'Bike':'37.10 to go!'});
Test.assertSimilar(iTri(2),{'Swim':'138.60 to go!'});
});
And the Output:
✘ Expected: '{ Bike: \'104.60 to go!\' }', instead got: '\'You\\\'re done! Stop running!\''
✘ Expected: '{ Bike: \'37.10 to go!\' }', instead got: '\'You\\\'re done! Stop running!\''
✘ Expected: '{ Swim: \'138.60 to go!\' }', instead got: '\'You\\\'re done! Stop running!\''
Also is it worth it to convert it to a switch statement? What are benefits/drawbacks of doing it as if/else vs switch?
Is it even worth it to try to convert it to a switch statement?
No. switch is only useful if you have multiple exact matches. This is not the case for you.
If you turn the problem around slightly then you can use a switch like this. Your switch is very close to this already
function iTri(s) {
var triLength = 140.60;
var result = {};
var str = ' to go!';
var lengthLeft = (triLength - s).toFixed(2);
switch(true) {
case s === 0:
return 'Starting Line... Good Luck!';
case s <= 2.4:
result.Swim = lengthLeft + str;
break;
case s <= 114.4:
result.Bike = lengthLeft + str;
break;
case s < 130.60:
result.Run = lengthLeft + str;
break;
case s < 140.60:
result.Run = 'Nearly there!';
break;
default:
return 'You\'re done! Stop running!';
}
return result;
}
console.log(iTri(0));
console.log(iTri(2));
console.log(iTri(50));
console.log(iTri(120));
console.log(iTri(135));
console.log(iTri(145));
