When trying to get my total to pop up, I can't seem to get it. Above this code in my .js file is the toggle check boxes; all of it works as of right now, but adding them together and coming up with a total in the txtTotal box is the only thing I'm struggling with.
var total;
var outputArea;
var btnCompute;
function ToggleBurgers() {
var checkbox = document.getElementById('chkBurgers');
var burgers = document.getElementById('divBurgers');
if (checkbox.checked) {
burgers.style.visibility = 'visible';
} else {
burgers.style.visibility = 'hidden';
}
}
function ToggleFries(){
var checkbox = document.getElementById('chkFries');
var fries = document.getElementById('divFries');
if (checkbox.checked) {
fries.style.visibility = 'visible';
} else {
fries.style.visibility = 'hidden';
}
}
function ToggleDrinks(){
var checkbox = document.getElementById('chkDrinks')
var drinks = document.getElementById('divDrinks');
if (checkbox.checked) {
drinks.style.visibility = 'visible';
}else {
drinks.style.visibility = 'hidden';
}
}
function ComputeTotal() {
var total = 0;
var burgers = document.getElementById('divBurgers');
var fries = document.getElementById('divFries');
var drinks = document.getElementById('divDrinks');

var radDrinkSoda = document.getElementById('radDrinkSoda');
var radDrinkWater = document.getElementById('radDrinkWater');
var outputArea = document.getElementById('txtTotal');
outputArea.innerHTML = total + divBurgers + divFries + divDrinks;
if (burgers.checked){

first off, you want to get rid of the else's in the block where you are checking if things are checked. that only allows you to get Burger or Fries or Drink, when you want to be able to get one of each.
so that should be:
if(burgers.checked){
if(radBurgerRegular.checked){
total = total + radBurgerRegular;
}
...
}
if(fries.checked){
...
}
if(drinks.checked){
...
}
Additionally, you are doing all of this adding to total, and then not doing anything with it.
Move this:
var outputArea = document.getElementById('txtTotal');
outputArea.innerHTML = total + divBurgers + divFries + divDrinks;
to the bottom of the function (and get rid of all the divBurgers, divFries stuff):
var outputArea = document.getElementById('txtTotal');
outputArea.innerHTML = total;
The next problem is that nowhere is the price actually being added. When you getElementById(), that value does not magically become the price that is in parenthesis. You need to replace total = total + radBurgerRegular with the price:
if(burgers.checked){
if(radBurgerRegular.checked){
total = total + 4.19;
}
...
}
lastly, you want to change the display area to a span instead of an input. change:
Total Meal Cost: <input type="text" name="txtTotal" id="txtTotal" />
to:
Total Meal Cost: <span id="txtTotal"></span>
and that should do it!
EDIT:
last thing, you need to change the following lines:
var burgers = document.getElementById('divBurgers');
var fries = document.getElementById('divFries');
var drinks = document.getElementById('divDrinks');
to this:
var burgers = document.getElementById('chkBurgers');
var fries = document.getElementById('chkFries');
var drinks = document.getElementById('chkDrinks');
because a div cannot be "checked" and will always return undefined (false).
Total is undefined in init.
Replace
var outputArea = document.getElementById('txtTotal');
outputArea.innerHTML = total
with
var outputArea = document.getElementById('txtTotal');
outputArea.innerHTML = 0;
Or possibly a better option is to initialize total.
total = 0;
var outputArea = document.getElementById('txtTotal');
outputArea.innerHTML = total;
The problem is inside the function ComputeTotal.
I propose you to take a look to the following implementation:
var total;
var outputArea;
var btnCompute;
function ToggleBurgers() {
var checkbox = document.getElementById('chkBurgers');
var burgers = document.getElementById('divBurgers');
if (checkbox.checked) {
burgers.style.visibility = 'visible';

}
}
function ToggleFries(){
var checkbox = document.getElementById('chkFries');
var fries = document.getElementById('divFries');
if (checkbox.checked) {
fries.style.visibility = 'visible';
} else {
fries.style.visibility = 'hidden';
}
}
function ToggleDrinks(){
var checkbox = document.getElementById('chkDrinks')
var drinks = document.getElementById('divDrinks');
if (checkbox.checked) {
drinks.style.visibility = 'visible';
}else {
drinks.style.visibility = 'hidden';
}
}
function ComputeTotal() {
var total = 0;
var burgersCost = 0;
var friesCost = 0;
var drinksCost = 0;
if (document.getElementById('chkBurgers').checked) {
var burgersObj = document.querySelector('input[name="radBurgers"]:checked');
var burgersValFromLabel = document.querySelector('label[for="' + burgersObj.id + '"]').textContent;
burgersCost = burgersValFromLabel.substring(burgersValFromLabel.lastIndexOf("(")+1,burgersValFromLabel.lastIndexOf(")"));
}
if (document.getElementById('chkFries').checked) {
var friesObj = document.querySelector('input[name="radFries"]:checked');
var friesValFromLabel = document.querySelector('label[for="' + friesObj.id + '"]').textContent;
friesCost = friesValFromLabel.substring(friesValFromLabel.lastIndexOf("(") + 1, friesValFromLabel.lastIndexOf(")"));
}
if (document.getElementById('chkDrinks').checked) {
var drinksObj = document.querySelector('input[name="radDrinks"]:checked');
var drinksValFromLabel = document.querySelector('label[for="' + drinksObj.id + '"]').textContent;

Within my set of price lists, I have radio buttons to select one option. That option then gets added to the total. I then want to have a number of checkboxes that you can select additional multiple options. However, the script only returns £NaN instead of the actual figure. As far as I am aware, I have assigned prices under the array correctly.
I'm stumped and can't find out why it isn't calculating.
As requested, I've included the code in one element. (full code is on codepen: https://codepen.io/Amnesia180/pen/RwKQOKP)
var burger_prices = new Array();
burger_prices["1x3oz"]=2;
burger_prices["2x3oz"]=3;
function getBurgerSizePrice()
{
var burgerSizePrice=0;
var theForm = document.forms["custom-burger"];
var selectedBurger = theForm.elements["burger-meat"];
for(var i = 0; i < selectedBurger.length; i++)
{
//if the radio button is checked
if(selectedBurger[i].checked)
{
burgerSizePrice = burger_prices[selectedBurger[i].value];
break;
}
}
return burgerSizePrice;
}
var burger_Sauces = new Array();
burger_Sauces["burgersauce"]=2;
burger_Sauces["spicyketchup"]=2;
function getBurgerSaucesPrice() {
var BurgerSaucesPrice = 0;
var theForm = document.forms["custom-burger"];
var selectedSauces = theForm.elements["selectedSauces"];
for (var i = 0; i < selectedSauces.length; i++) {
if(selectedSauces[i].checked){
BurgerSaucesPrice += burger_Sauces[selectedSauces[i].value];
break;
}
}
return BurgerSaucesPrice;
}
function calculateTotal()
{
var burgerPrice = getBurgerSizePrice() + getBurgerSaucesPrice();
var divobj = document.getElementById('totalPrice');
divobj.style.display='block';
divobj.innerHTML = "Total Price For the Burger £"+burgerPrice;
}

You're trying to access value on input elements but that doesn't exist as it's attribute in your HTML. You can just use the id attribute instead since those map with the keys in burger_Sauces object.
Note: you were seeing NaN because .value was returning undefined and a number operation on undefined results in NaN. Also you might want to calculate burger sauces price only when a burger patty is selected. I haven't added that check but just a heads up.
var burger_prices = {};
burger_prices["1x3oz"]=2;
burger_prices["2x3oz"]=3;
function getBurgerSizePrice()
{
var burgerSizePrice=0;
var theForm = document.forms["custom-burger"];
var selectedBurger = theForm.elements["burger-meat"];
for(var i = 0; i < selectedBurger.length; i++)
{
//if the radio button is checked
if(selectedBurger[i].checked)
{
burgerSizePrice = burger_prices[selectedBurger[i].value];
break;
}
}
return burgerSizePrice;
}
var burger_Sauces = {}
burger_Sauces["burgersauce"]=2;
burger_Sauces["dirtymayo"]=2;
burger_Sauces["spicyketchup"]=2;
function getBurgerSaucesPrice() {
var BurgerSaucesPrice = 0;
var theForm = document.forms["custom-burger"];

if(selectedSauces[i].checked){
BurgerSaucesPrice += burger_Sauces[selectedSauces[i].id];
}
}
return BurgerSaucesPrice;
}
function calculateTotal()
{
var burgerPrice = getBurgerSizePrice() + getBurgerSaucesPrice();

Your code almost worked. Your only problem was this line:
BurgerSaucesPrice += burger_Sauces[selectedSauces[i].value];
You should have typed it:
BurgerSaucesPrice += burger_Sauces[selectedSauces[i].id]; /* use id not value */
You also forgot to assign a value for dirtymayo, so I decided to choose an arbitrary value for it.
burger_Sauces["dirtymayo"]=3;
And lastly, you had a break in the for loop that calculates the Sauce total. That will cause it to stop counting all other selected sauces after it counts the first selected on. So I had to comment that break out.
// break; // you should continue to check for other sauces
My guess is that you copied the logic from the radio button group (which makes sense to exit from for loop once you encountered the first selected option), and then forgot to remove the break from the checkbox group.
var burger_prices = new Array();
burger_prices["1x3oz"]=2;
burger_prices["2x3oz"]=3;
function getBurgerSizePrice()
{
var burgerSizePrice=0;
var theForm = document.forms["custom-burger"];
var selectedBurger = theForm.elements["burger-meat"];
for(var i = 0; i < selectedBurger.length; i++)
{
//if the radio button is checked
if(selectedBurger[i].checked)
{
burgerSizePrice = burger_prices[selectedBurger[i].value];
break;
}
}
return burgerSizePrice;
}
var burger_Sauces = new Array();
burger_Sauces["burgersauce"]=2;
burger_Sauces["spicyketchup"]=2;
burger_Sauces["dirtymayo"]=3;
function getBurgerSaucesPrice() {
var BurgerSaucesPrice = 0;
var theForm = document.forms["custom-burger"];
var selectedSauces = theForm.elements["selectedSauces"];

if(selectedSauces[i].checked){
BurgerSaucesPrice += burger_Sauces[selectedSauces[i].id]; /* use id not value */
// break; // you should continue to check for other sauces

return BurgerSaucesPrice;

I get always red background and if the answer is correct, maybe document.getElementByName("0").value is not getting a number to make true the condition
var radio1 = document.getElementByName("0").value;
if (answers[0] == radio1) {
document.getElementById("0").style.backgroundColor="#00FF00";
} else {
document.getElementById("0").style.backgroundColor="#e83f3f";
}
var radio1 = document.getElementByName("0").value;
if (answers[0] == radio1) {
Probably your error is in this line of code, the id="0" is a div and you are trying to get the value of it, this might result into undefined and the value answer[0] is 1, thus 1 is not equal to radio1, thus it is always getting into the else block.

I have a college assignment to complete which requires me to calculate the price of a hotel and multiply it by the number of days plus any extras to be added to the price of the hotel.
Unfortunately, the code I've provided doesn't work and I'm not sure how I can multiply the hotel price with the holiday duration... If anyone can help me with this problem, I would gladly appreciate the help.
Here is the html code for my assignment:

<input type="radio" name="range" value="0-999">0-1000
<input type="radio" name="range" value="1000-2000">1000-2000
Basically if you select a category from checkbox lets say shoes, then divs only with shoes should get displayed. Then if you filter the results with price, some starting and ending limit, it should show shoes category divs falling in that specific range, Not out of that range.
And in between if you select brand checkbox also.then it should match for all the three checkboxes that is from category and brand and price range
For example:- we selected shoes checkbox, it should show shoe divs; then if we select range as 1000-2000, then it should show shoe1 and shoe2 and not shoe3.
if u select shoe category and then if you select brand checkbox as well.it should filter out on both checkbox basis,and then it should look for price range and match the results,filter the divs.
Please help on this.
<script type="text/javascript">
$("input.category").prop("checked", true).change(function (e) {
$("input[name=range]:checked").trigger("change");
});
$("input.brand").prop("checked", true).change(function (e1) {
$("input[name=range]:checked").trigger("change");
});
$("input[name=range]").change(function (e) {
var toggle = this.checked;
var range = this.value.split('-');
var rangeFrom = parseInt(range[0]);
var rangeTo = parseInt(range[1]);
$(".content[data-price]").each(function(){
var $this = $(this);
var categoryActive = $("#" + $this.data("category")).prop("checked");
var brandActive = $("#" + $this.data("brand")).prop("checked");
var price = parseFloat($this.data('price'));
$this.toggle(price >= rangeFrom && price <= rangeTo && categoryActive);
$this.toggle(price >= rangeFrom && price <= rangeTo && $("#" + $this.data("brand")).prop("checked"));
});
});
</script>
i tried this script with my one buddy's help.
Thanks and Google if You can help on this
you can do something like this :
$("#shoes").click(function (e) {
$('.content[data-category=shoes]').toggle();
});
