Parsing BTC jQuery calculator to USD

I have this investment calculator in javascript/jquery. It calculates the profit someone would have, based on specific plans. It's written to work with bitcoin values, which goes like this 0.36000000 BTC. I just need to parse it to 3,6 format.

Got it working, thank you. Just changed the number of toFixed(n)

$.getJSON( "https://api.coindesk.com/v1/bpi/currentprice/usd.json",
function( data) {
var amountInBtc = 0.005; //convert 0.005 btc to usd
var exchangeRate = parseInt(data.bpi.USD.rate_float);
var amount = amountInBtc * exchangeRate;
console.log(amount);

Solve mathematical function in javascript

I have created this function for a shopping basket. To be simple, i have x products with (2 checkbox + quantity input) for each.
The first checkbox add +3, second +8, to the product price. It's like (3+8+price)*quantity. At the end of the page, i have the total result (like product1 + product2...Etc)
The problem is: If i'm posting the form with new quantities, and going back to the page, i have the default result (total price) (of course, checkbox are checked + new quantity with PHP).
Here is my function:
$(function(){
var item_prices = 0;
var total_item_prices = 0;
var total_unique_item_prices = 0;
var total_price = 0;
$.each($('*[data-item-price]'), function(index, element) {
var item_price = $(element).data("item-price");
total_unique_item_prices = parseInt($('[data-total]').html()) + item_price;
total_price = total_unique_item_prices;
$('[data-total]').html(total_unique_item_prices);
})
$.each($('*[data-item-price]'), function(index, element) {
var item_price = $(element).data("item-price");
var price_of_options = 0;
var quantity = parseInt($(element).find('input[data-quantity]').val());
$.each($(element).children().find("[data-price]"), function(index, element2) {
$(element2).click(function(){
var actual_price = parseInt($('[data-total]').html());
var actual_item_price = parseInt($(element).find('[data-item-total]').html());
var price = $(element2).data("price");
if ($(element2).is(':checkbox') && $(element2).is(':checked')) {
price_of_options += price;
$(element).find('[data-item-total]').html(actual_item_price + (price * quantity));
$('[data-total]').html(actual_price + (price * quantity));
}
else {
price_of_options -= price;
$(element).find('[data-item-total]').html(actual_item_price - (price));
$('[data-total]').html(actual_price - (price * quantity));
}
})
})
$(element).find('input[data-quantity]').bind('keyup mouseup', function () {
var new_quantity = parseInt($(element).find('input[data-quantity]').val());
var quantity_dif = new_quantity - quantity;
var actual_price = parseInt($('[data-total]').html());
if (quantity_dif > 0) {
quantity_dif = new_quantity - quantity;
$(element).find('[data-item-total]').html((item_price + price_of_options) * new_quantity);
$('[data-total]').html(actual_price + ((item_price + price_of_options) * quantity_dif));
}
else {
quantity_dif *= -1;
quantity = parseInt($(element).find('[data-quantity]').val());
$(element).find('[data-item-total]').html((item_price + price_of_options) * new_quantity);
$('[data-total]').html(actual_price - ((item_price + price_of_options) * quantity_dif));
}
quantity = parseInt($(element).find('[data-quantity]').val());
})
})
})
As I said, code is working: https://jsfiddle.net/redbean/4dy38ye4/1/ Just not when i'm reloading the webpage.
I'm not english, be kind about this. I'm trying to do the best to be clear!

math function wont work

I have a text input called "textmoney". In my jQuery i have a variable called "dailyE". This var is basically "textmoney".val / 365. This whould show an estimated amount made daily. What i can't get to work is my "stats", which basically show statistics of the number inputted in "textmoney". I can't get it to display a simple math function in statFunction. I've tried to fix this for a while now.
here is my jQuery:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script>
$(document).ready(function() {
var $demo = $('#demo');
var $textMoney = $('#textmoney');
var $moneydiv = $('#moneydiv');
var $stat = $('#stat');
var dailyE = $textMoney.val() / 365;
var $second = (dailyE / 24) / 60 / 60 / 60;
var $minute = (dailyE / 24) / 60 / 60;
var $hour = (dailyE / 24);
var $day = dailyE;
var $week = dailyE * 7;
var $month = (dailyE * 7) * 30;
var $year = (dailyE * 7) *30 *12;
var $secondp = $('#second');
var $minutep = $('#minute');
var $hourp = $('#hour');
var $dayp = $('#day');
var $weekp = $('#week');
var $monthp = $('#month');
var $yearp = ('#year');
$('#stat').hide();
function getmoney(){
var money = $textMoney.val();
if (isNaN(money) || money === '') {
$demo.text('You aint enter no $$$$$$');
} else {
var dailyE = $textMoney.val() / 365;
$demo.text('$' + dailyE + ' per day');
}
}
function statFunction() {
$stat.show();
$secondp.text("$second");
}
// on enter key
$textMoney.keydown(function(e) {
if (e.which === 13) {
getmoney();
$('#stat').show();
} else if ($(this).val() === '') {
$demo.text('');
$('#stat').hide();
}
}).mouseover(function() {
$(this).css('border', '1px solid black');
}).mouseout(function() {
$(this).css('border', '1px solid grey');
});
// on click
$moneydiv.click(function(){
getmoney();
$('#stat').show();
});
$stat.click(function() {
statFunction();
})
});
</script>

missing $ for var $yearp = ('#year');
Please correct it as
var $yearp = $('#year');

How to "echo" or show pictures from Javascript

I'm trying to use the below code to reflect different pictures of the moon into an HTML doc. Of course i've added the Jquery and Javascript tags.
I've been looking at this for hours and trying different things but I can't find out what to put into HTML code that will actually show or echo the pictures.
What should I put into the "moonImage.src = "pix/moon" + truncPhase + ".png";" part of the code? I don't understand how to essentially echo the photos. Help please?:

ok, well thats then easy.
first of all, you might want to check out jquery. with jquery it would be something like this.
<img src="" id="my_image" />
in javascript then (with jquery)
// the `myLinkToImage` is hopefully the variable of your path
$("#my_image").attr("src", myLinkToImage);
as you can see I´m using #. That is a typical jQuery Selector. You might check out more of them here
in javascript without jquery
document.getElementById("my_image").src = myLinkToImage;

Calculation of per unit of Electricity [closed]

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center.

I think this will do :)

Your code needs to be separated - as well comments are useful to help others understand the purpose of your code. Here's a working example of one:
function check()
{ var initialRate = 4; // electricity charged at this rate below 200
var standardRate = 5; // amount of electricity between 200 and 400 charged at this rate
var overageRate = 6; // the part of electricity usage over 400 at this rate
var electricityUsage = +document.getElementById('bill').value; // convert String to Number
if (isFinite(electricityUsage) || electricityUsage < 0) {
alert('The number entered was invalid, or was less than 0.');
return;
}
// calculates the total
alert(
electricityUsage > 400
? initialRate * 200 + standardRate * 200 + overageRate * (electricityUsage - 400)
: electricityUsage > 200
? initialRate * 200 + standardRate * (electricityUsage - 200)
: initialRate * electricityUsage
);
}

Try this:
function check()
{
// Algorithm
// Slabs : 200 | 400 | ...
// Amoun : 4 | 5 | 6
slabs = [200, 400]
rate = [4, 5, 6]
var total = document.getElementById('bill').value;
// Over the head
if (total > slabs[1]) {
amount = slabs[0] * rate[0] + (slabs[1] - slabs[0]) * rate[1] + (total - slabs[1]) * rate[2];
} else if (total > slabs[0]) {
amount = slabs[0] * rate[0] + (total - slabs[0]) * rate[1];
} else {
amount = total * rate[0];
}
alert("Total charge: " + amount);
}

I think I have it at last. There are three charge-bands and you need to know what portion of a value is in each band. Then you need to apply appropriate multipliers to the amount in each band.
If I'm right, then the code is painfully simple :
function check() {
var a = Number(document.getElementById('bill').value);
var n = 200;
var tot1 = Math.min(n, a);
a = a - n;
var tot2 = Math.max(0, Math.min(n, a));
a = a - n;
var tot3 = Math.max(0, a);
return tot1 * 4 + tot2 * 5 + tot3 * 6;
}
If there were more bands then we would do the calcs in a loop but for three bands this is adequate.
Note: The function returns the calculated total.

See this: Sample
function check()
{
var tot = 0,tot1=0,tot2=0,tot3=0;
var a = document.getElementById('bill').value;
tot1 = (a<=200) ? (a * 4) : 800;
tot2 = (a<=400) ? ((a-200) * 5): 1000;
tot3 = (a-400) > 0 ? ((a-400) * 6): 0;
tot = tot1 + tot2 + tot3;
var msg = "Total Charge: "+tot+"\n Details\n < 200 : "+tot1;
msg += (tot2 != 0) ? "\n200 to 400 : "+tot2 : "";
msg += (tot3 != 0) ? "\n>400 : "+ tot3 : "";
alert(msg);
}
