TypeError: tempTable is null - javascript

I'm writing a script that prompts you to enter a low temperature and a high one. When you click add temperatures, it displays todays date, low temp, and high temp, and the average of low temps and high temps. Each time you enter these temps, the previous date before the last is displayed with those temps and the averages. When I try to run the code I get this: TypeError: tempTable is null. Any suggestions?
(function() {
//Array to hold temp data
var temperatures = new Array();
// function which updates the array
function addTemp() {
var lowTemp = document.getElementById("lowTemp").value;
var highTemp = document.getElementById("highTemp").value;
if (lowTemp.length === 0 || highTemp.length === 0) {
alert("Valid low and high temperatures must be entered!");
} else {
document.getElementById("output").style.display = "block";
// Add new temperatures to the array
// Current date
var d = new Date();
if (temperatures.length == 0) {
// Current date if it is 1st temperature
temperatures.push(new Array(d.getMonth(), d.getDate(), d.getFullYear(), lowTemp, highTemp));
} else {
// 1 day before last date
newDate = temperatures[temperatures.length - 1][1] - 1;
temperatures.push(new Array(d.getMonth(), newDate, d.getFullYear(), lowTemp, highTemp));
}
// Create the output table
var tempTable = document.getElementById("tempTable");
tempTable.innerHTML = "<tr><th>Date</th><th>Low Temperatures</th><th>High Temperatures</th></tr>";
// Loop over the array and create the table
// Also calculate the averages
var avgLow = 0;
var avgHigh = 0;
temperatures.forEach(function(entry) {
var newRow = document.createElement('tr');
newRow.innerHTML = '<td>' + entry[0] + '/' + entry[1] + '/' + entry[2] + '</td><td align="right">' + entry[3] + '</td><td align="right">' + entry[4] + '</td>';
tempTable.appendChild(newRow);
avgLow += parseInt(entry[3]);
avgHigh += parseInt(entry[4]);
});
// Add the row for average
avgLow /= temperatures.length;
avgHigh /= temperatures.length;
avgLow = avgLow.toFixed(1)
avgHigh = avgHigh.toFixed(1)
var newRow = document.createElement('tr');
newRow.innerHTML = '<td>Averages</td><td align="right">' + avgLow + '</td><td align="right">' + avgHigh + '</td>';
tempTable.appendChild(newRow);
//Add row for lowest temp
var minTemp = Math.min.apply(lowTemp.value);
var key = lowTemp.indexOf(d);
var newRow = document.createElement('tr');
newRow.innerHTML = '<td colspan="3"> The lowest temp of' + minTemp + 'occured on' + key + '</td>';
tempTable.appendChild(newRow);
}
return false;
}
function init() {
'use strict';
document.getElementById('theForm').onsubmit = addTemp;
} // End of init() function.
window.onload = init;
})();

The error means that when your code executed at that time temptable was not set possibly because your JS code is rendering prior to DOM element loaded.
var tempTable = document.getElementById("tempTable");
Also execute init() in DomContentLoaded instead of window.onload.
document.addEventListener("DOMContentLoaded", function(event) {
init();
});

Javascript how to define an object by array of objects

I recently started learning html/javascript and I want a temporary object to be filled with one of the objects from an array based on the current page number.
loadnextpage();
function loadnextpage() {
var curpage = allcontent[pagenumber];
pagenumber++;
changeDiv('title', '<span>' + curpage.pageNumber + '</span>' + curpage.title);
}
But when I try to run the code it keeps giving me an error message that curpage is undefined, after that it keeps running and thus the last line of code gives an error, when I ask for curpage.pageNumber. After that it stops running the code.
image clipping of my code with error message
What am I doing wrong?
edit:
here is the entire code:
var pagenumber = 0;
var receipt = [];
var price = 0;
var text = '{"page": [{"pageNumber": "1","title": "kies je formaat","optionName": "size","option": [{"text": "klein","value": "small","extraPrice": "100"},{"text": "middel","value": "medium","extraPrice": "200"},{"text": "groot","value": "large","extraPrice": "300"}]},{"pageNumber": "2","title": "kies je kleur","optionName": "colour","option": [{"text": "rood","value": "red","extraPrice": "10"},{"text": "groen","value": "green","extraPrice": "20"},{"text": "blauw","value": "blue","extraPrice": "30"}]}]}';
var allcontent = [];
allcontent = JSON.parse(text);
var imgpath = 'img/';
loadnextpage();
function loadnextpage(){
var curpage = allcontent[pagenumber];
pagenumber++;
changeDiv('title', '<span>' + curpage.pageNumber + '</span>' +
curpage.title);
var radiobuttons = '';
var radiobuttonid = [];

Google Script/JavaScript Converting time between timezones

I travel a lot, and I often have appointments (such as flights) that start in one timezone and end in another. I need to know both the local and UTC time that each event will start and end.
I use Google Calendar and specify the different start and end timezones in the calendar events.
I have written a script that pulls my agenda for a given time period, which shows everything in my local time, which is fine.
I am having difficulty getting the local time.
When I retrieve the events, the time is shown in my local time.
I can retrieve the timezone in the format Europe/Rome, etc. but this doesn't help me display the local time.
Attached is a screenshot of an entry in my calendar:
And here is how the event is seen from my script (taken from the log file):
Start: 2017-03-29T16:35:00+01:00, startTimeZone: Europe/Berlin.
End: 2017-03-29T22:30:00+01:00, endTimeZone: Asia/Qatar
These times should be Start: 17:35 and End: 00:30, respectively.
Has anyone got any ideas on how to get the local time or convert between timezones?
Hopefully this might help you.
function timezones()
{
var today = new Date();
var hour = 3600000;
var tz = '';
today = new Date(today.getTime() + (13 * hour));
var s = '<div id="mydiv">';
for(var i = 12; i >= -11; i--)
{
if(i > 0){ tz = 'GMT+' + i;}
if(i == 0){tz = 'GMT';}
if(i < 0){tz = 'GMT' + i;}
today = new Date(today.getTime() - hour);
s += '<div class="myDates">' + Utilities.formatDate(today,"GMT", "'Date:'yyyy-MM-dd' Time:'HH:mm:ss") + 'TimeZone; "' + tz + '"</div>';
}
s += '</div>';
dispStatus('Timezones', s);
}
This is the display routine that I use.

if(!modal)
{
SpreadsheetApp.getUi().showModelessDialog(htmlOutput, title);
}
else

}
}
And here is a timezone map.

Creating a local variable to keep track of months on a calendar in javascript.

Here I have below a full html page for a calendar creation, copy it over to see what it does.
I have two buttons below that can increment month by one. My problem is because I can instantiating var month= date.getMonth() at the top of the page, the global variable month only allows me to increment and decrement by 1, how can I let month be set as a local variable so I am able to increment to more than just 1. Here is the code: I'm sure copy paste will work:
Below I have posted my my button handlers to increase month/decrease month.
<script type="text/javascript">
printCalendar(year,month,divDestination);
function printCalendar(year,mth,divDestination){
var currentmonth = mth;
var myOutput=document.getElementById(divDestination)
myOutput.innerHTML=makeCalendar(year,mth)
}
function prevMonth(m){
m--;
var currentmonth = m;
alert(m);
if(m < 0)
{
m = 11;
year--;
}
printCalendar(year,currentmonth,divDestination);
}
function nextMonth(m){
m++;
var currentmonth = m;
if(m > 11)
{
m=0;
year++;
}
printCalendar(year,currentmonth,divDestination);
}
function test(div){
var myOutput=document.getElementById("divCalendar")
myOutput.innerHTML += eventmonth;
}
</script>
<div align="center" id="divCalendar"></div>
<div align="center" id="myButtons">
<input type="button" onclick="test('divCalendar')" value="Say hi" />
<input type="button" onclick="prevMonth(month,'divCalendar')" value="Previous"/>
<input type="button" onclick="nextMonth(month,'divCalendar')" value="Next" />
<input type="button" onclick="printCalendar(year,month,'divCalendar')" value="Reload Calendar" />
Here below is my makeCalendar function
var myDate = new Date();
var month = myDate.getMonth();
var year = myDate.getFullYear();
var divDestination="divCalendar";
function leapYear(yr) {
if (yr < 1000) yr+=1900
return((yr%4 == 0) && ((yr%100 == 0) || (yr%400 ==0)))
}
function startCol(width, height, color){
return('<TD WIDTH=' + width + ' HEIGHT=' + height + '>' + '<FONT COLOR="' + color + '">');
}

{
monthSelected = monthSelected + 1
var holiday = ""
var HolidayName = new Array (1, 1, "New Year's Day",7, 1, "Canada Day",12, 25, "Christmas Day",12, 26, "Boxing Day", 2,14,"Valentine's Day")
for(var index = 0; HolidayName.length >= index; index++)
{
if(HolidayName[index] == monthSelected && HolidayName[index+1] == theday)
{
holiday = HolidayName[index+2]
}
}
return holiday
}

var weekDays = new Array("Sun", "Mon", "Tues", "Wed", "Thurs", "Fri", "Sat")
var mthSz = days[mth]
var mthName = months[mth]
var firstDyofMnth = new Date(yr, mth, 1)

Lets try to trim this down further to the money bits. Here's basically what you are doing.
var month = new Date().getMonth()
var nextMonth = function(m) {
m++;
setMonthSomewhere(m);
};
nextMonth(month);
So what happens is that you pass your global, which is accessible everywhere anywhere, to the nextMonth() function. And function arguments basically declare a local variable, which is sets to the passed in value. You now have a global month variable set to 1, and a totally different m local to the nextMonth() function also set to 1. You then increment the local variable m to 2, which has no effect on the global variable.
Instead, simply don't pass it in. Manipulate the global directly.
var month = new Date().getMonth()
var nextMonth = function() {
month++;
setMonthSomewhere(month);
};
nextMonth();
Now nextMonth() increments the global month variable directly, changing it's value.
You are using the global variable month in your handler <input type="button" onclick="nextMonth(month,'divCalendar')" value="Next" /> but you never update that global variable.
Why not try removing the first argument from your nextMonth function and instead of using m you use month.
function nextMonth(){
month++;
if(month > 11)
{
month=0;
year++;
}
printCalendar(year,month,divDestination);
}
(note your usage of "currentMonth" variable is probably wrong too so I removed that)
But I think that your design is a little flawed - because you are using global variables and putting them on the global namespace, you will have a tough time if you ever need to render 2 calendars or if ever some other javascript wants to use the variable name "month" or "year".
EDIT (Adding a better solution)
I would recommend though that instead of passing in numbers to your function, that you pass an entire date object - because that will make the code a lot simpler.
function printCalendar(date, divDestination) {
var myOutput=document.getElementById(divDestination)
myOutput.innerHTML=makeCalendar(date.getFullYear(), date.getMonth());
}
function nextMonth(date, divDestination) {
date.setMonth(date.getMonth()+1);
printCalendar(date, divDestination);
}
function prevMonth(date, divDestination) {
date.setMonth(date.getMonth()-1);
printCalendar(date, divDestination);
}
Now because you passed a Date object, the nextMonth and prevMonth functions actually modify the object, so that next time you call the Date will be updated with the new month.
Here is a fiddle that shows the solution using a date object

Change event not Working

The value of to[0] is changing dynamically due to a javascript calender. In this code, change event is not working and I don't know...why so???
Jquery Code is:
$(document).ready(function() {
$("input[name='to[0]']").change( function() {
var b1 = $("input[name='to[0]']").val();
alert(b1);
});

Use this code instead of your code:
$("input:text[name=to[0]]").blur( function() {
var b1 = $(this).val();
alert(b1);
});
As shown on http://jsfiddle.net/RxsL8/1/ change event is never fired for an input if its value is changed dinamycally (and not by explicit user action)
so you would probably need to use some internal function/callbacks provided by your datepicker plugin, or add some code to run when a date is chosen
after your edit:
your input is updated on updateDateField function, right here
if (dateString)
targetDateField.value = dateString;
so add here a callback function
