my javascript isn't the best. I have some code here in the form of a calculator:
https://jsfiddle.net/yadL05aL/
my javascript:
// Get a list of your products and pop them into a dropdownlist
function GetProducts() {
var products = V12.getFinanceProducts();
var ddlProducts = document.getElementById('productsList');
for (var i = 0; i < products.length; i++) {
var newItem = new Option(products[i].name, products[i].productId);
ddlProducts.appendChild(newItem);
}
}
// Get details of repayments for the product selected
function CalculateRepayments() {
var productId = $('#productsList').val(); // selected product
var financeProduct = V12.getFinanceProduct(productId); // get the object
var cashPrice = $('#cashPrice').val();
var depositFactor = $('#deposit').val();
var deposit = cashPrice * (depositFactor / 100);
var payments = V12.calculate(financeProduct, cashPrice, deposit);
PopulateDescription(payments);
}
function UpdateLoanInfo() {
$('#cashPrice').val($('#cpRange').val());
$('#deposit').val($('#depRange').val());
CalculateRepayments();
}
// Show repayment plan details in the description
function PopulateDescription(payments) {
$('#lblFinalPayment').html('');
$('#lblDeposit').html('£' + payments.deposit);
$('#lblInitPayments').html('£' + payments.initialPayments);
$('#lblTotalRepayable').html('£' + payments.amountPayable);
$('#lblInterest').html(payments.apr + '%');
if (payments.initialPayments != payments.finalPayment && payments.finalPayment > 0) {
$('#lblMonths').html(payments.months - 1);
$('#lblFinalPayment').html(' and a final payment of £' + payments.finalPayment);
} else {
$('#lblMonths').html(payments.months);
}
}
// Firing this will loop through your V12 products and grab the product with the lowest
// possible monthly payments.
function GetLowestMonthlyPayments() {
var products = V12.getFinanceProducts();
var lowestMonthlyPayment = 0;
var lowestMonthlyPaymentProductId = 0;
for (var i = 0; i < products.length - 1; i++) {
var product = V12.getFinanceProduct(products[i].productId);
var cashPrice = $('#cashPrice').val();
var depositFactor = $('#deposit').val();
var deposit = cashPrice * (depositFactor / 100);
var payments = V12.calculate(product, cashPrice, deposit);
var monthlyPayment = payments.initialPayments;
if (parseFloat(lowestMonthlyPayment) > parseFloat(monthlyPayment) || lowestMonthlyPayment == 0) {
lowestMonthlyPayment = payments.initialPayments;
lowestMonthlyPaymentProductId = product.productId;
}
}
$("#productsList").val(lowestMonthlyPaymentProductId);
CalculateRepayments();
}
// Ready up our events
(function ($) {

});
$('#cpRange, #depRange').on("input", function () {

$('#lowestMonthlyPayments').click(function () {

});
$('#cashPrice, #deposit').keyup(function () {
var cp = $('#cashPrice').val();
var dep = $('#deposit').val();
$('#cpRange').val(cp);
$('#depRange').val(dep);
CalculateRepayments();
});
//spinner//
$('<div class="quantity-nav"><div class="quantity-button quantity-up">+</div><div class="quantity-button quantity-down">-</div></div>').insertAfter('.quantity input');
$('.quantity').each(function() {
var spinner = jQuery(this),
input = spinner.find('input[type="number"]'),
btnUp = spinner.find('.quantity-up'),
btnDown = spinner.find('.quantity-down'),
min = input.attr('min'),
max = input.attr('max');
btnUp.click(function() {
var oldValue = parseFloat(input.val());
if (oldValue >= max) {
var newVal = oldValue;
} else {
var newVal = oldValue + 100;
}
spinner.find("input").val(newVal);
spinner.find("#cpRange").val(cp);
spinner.find("#depRange").val(dep);
spinner.find("input, #cashPrice").trigger("change");
});
btnDown.click(function() {
var oldValue = parseFloat(input.val());
if (oldValue <= min) {
var newVal = oldValue;
} else {
var newVal = oldValue - 100;
}
spinner.find("input").val(newVal);
spinner.find("input").trigger("change");
});
});
})(jQuery);
what I am trying to achieve is when you click on the plus and minus buttons in the cash price input, the bottom labels reflect the decrease or increment changes to the deposit / monthly repayments & APR.
Can anyone please point me in the right direction?
Kind regards

I did not want to post this long question, but I am lost and do not know what to do. Thanks and sorry.
I'm having a problem when trying to multiply the totalPallets by the price-per-pallet ($25) and then showing that in the productSubTotal box. With the code as it is right now, the quatity total shows but when I try to get the price result, it doesn't show the operation. Also, if I try changing anythung from the code, the whole thing breaks down. I'll be thankful if anyone could help me. Thanks

I want to retrieve a random row from the table of meals, how is the way to do that?
My code :
var transaction = db.transaction(["meals"], "readonly");
var store = transaction.objectStore("meals");
var index = store.index("time"); // to search in the field time type
range = IDBKeyRange.only(3); // 3 means it is a lunch
index.openCursor(range).onsuccess = function (e) {
var dt = event.target.result;
if (dt) {
var s = dt.value['fno1'];
}
};
Instead of advancing one row at a time until you hit your random result, what about using advance(n) to jump up a random set? Here is a complete example. It assumes two buttons to seed data and to call the random selection. I'm going to be blogging this Monday.
/* global $,document,indexedDB,console */
/**
* Returns a random integer between min and max
* Using Math.round() will give you a non-uniform distribution!
*/
function getRandomInt (min, max) {
return Math.floor(Math.random() * (max - min + 1)) + min;
}
$(document).ready(function() {
var db;
var openRequest = indexedDB.open("randomidb",1);
openRequest.onupgradeneeded = function(e) {
var thisDB = e.target.result;
console.log("running onupgradeneeded");
if(!thisDB.objectStoreNames.contains("notes")) {
thisDB.createObjectStore("notes", {autoIncrement:true});
}
};
openRequest.onsuccess = function(e) {
console.log("running onsuccess");
db = e.target.result;
$("#seedButton").on("click", function() {
var store = db.transaction(["notes"],"readwrite").objectStore("notes");
for(var i=0; i<10; i++) {
var note = {
title:"Just a random note: "+getRandomInt(1,99999),
created:new Date()
};
var request = store.add(note);
request.onerror = function(e) {
console.log("Error",e.target.error.name);
//some type of error handler
};
request.onsuccess = function(e) {
console.log("Woot! Did it");
};
}
});
$("#randomButton").on("click", function() {
//success handler, could be passed in
var done = function(ob) {
console.log("Random result",ob);
};
//ok, first get the count
var store = db.transaction(["notes"],"readonly").objectStore("notes");
store.count().onsuccess = function(event) {
var total = event.target.result;
var needRandom = true;
console.log("ok, total is "+total);
store.openCursor().onsuccess = function(e) {
var cursor = e.target.result;
if(needRandom) {
var advance = getRandomInt(0, total-1);
console.log("going up "+advance);
if(advance > 0) {
needRandom = false;
cursor.advance(advance);
} else {
done(cursor);
}
} else {
done(cursor);
}
};
};
});
};
});
OK, I have developed this solution and it works just perfect to retrieve random row from table:
var transaction = db.transaction(["meals"], "readonly");
var store = transaction.objectStore("meals"); // name of table
var index = store.index("time"); // time is name of field and it is a number
range = IDBKeyRange.only(2); // query when time = 2
var y = 1;
var z = true;
var x = 0; // it will equal the random number
index.openCursor(range).onsuccess = function (e) {
var dt = event.target.result;
if (z) {
x = RandInt(1, dt.key); // get random number between 1 and count of rows
z = false; // to only make the above line one time only
}
if (dt) {
if (x == y) {
var s = dt.value['fno1'];
}
else
{ y += 1; dt.continue();}
}
};
Function to get the random number between two values :
function RandInt(min, max) {
return Math.floor(Math.random() * (max - min + 1) + min);
}
I am using NoUiSlider in some pages which could have 3, 4 or 5 sliders (http://refreshless.com/nouislider/).
I need to set the sliders to have a total value which is constrained to 100, so that if I raise the value of a slider, the others should lower a little and vice-versa, but I really don't know how to do it.
Can anyone help me please? Thanks!
jQuery code:
$(".slider.tied").each(function() {
var context = $(this).addClass("noUiSlider");
var input = context.prev(".amount"); // the input containing the actual slider value
var val = input.val();
var min = input.data("min");
var max = input.data("max");
context.noUiSlider({
range: [min, max],
start: val,
step: 1,
handles: 1,
slide: function() {
var value = $(this).val();
input.val(value);
}
});
});
A possible solution:
var init = true;
var elements = $(".multislider").children(".slider.tied").length;
var MAX = 100;
var initValue = (MAX / elements) >> 0;
var InitMod = MAX % elements;
$(".slider.tied").each(function() {
var slidersTied = $(".slider.tied");
var context = $(this);
var input = context.prev(".amount");
var val = input.data('answer');
var min = input.data('min');
var max = input.data('max');
var range = 1;
var proceed = false;
$(this).empty().slider({
value: val,
min: min,
max: max,
range: range,
animate: "slow",
create: function(event, ui){
if (InitMod > 0) {
$(this).slider('value', initValue + 1);
$(this).prev('.amount').val(initValue + 1);
InitMod = InitMod - 1;
}
else
{
$(this).slider('value', initValue);
$(this).prev('.amount').val(initValue);
}
},
slide: function(e, ui) {
// Update display to current value
$(this).prev('.amount').val(ui.value);
var current = ($(this).index() / 2) >> 0;
var total = 0;
var counter = 0
slidersTied.not(this).each(function() {
total += $(this).slider("option", "value");
counter += 1;
});
total += ui.value;
if (total != MAX){
proceed = true;
}
var missing = MAX - total;
console.log("missing: " + missing);
counter = 0;
if(proceed) {
//load elements array
var elements = [];

Here's a fiddle:

Take care of setting the value of MAX variable to desired value (the sum of all slider's value together...
I meet a trouble with a function. actually I need to make this function to perform a calculation on some text fields. When I worked on a single line no problems. But recently, someone asked to make a table with multiple lines (one line can be added dynamically) so, I do the following function so that it can not only duplicate line but id change all the fields concerned, so I add class to these fields. therefore I proceed as follows:
function clone(line) {
newLine = line.cloneNode(true);
line.parentNode.appendChild(newLine);
var tab = document.getElementsByClassName('libelle_debours')
var i = -1;
while (tab[++i]) {
tab[i].setAttribute("id", "_" + i);
};
var cab = document.getElementsByClassName('ht_no_tva')
var j = -1;
while (cab[++j]) {
cab[j].setAttribute("id", "_" + j);
};
var dab = document.getElementsByClassName('ht_tva')
var k = -1;
while (dab[++k]) {
dab[k].setAttribute("id", "_" + k);
};
var eab = document.getElementsByClassName('taux')
var l = -1;
while (eab[++l]) {
eab[l].setAttribute("id", "_" + l);
};
var fab = document.getElementsByClassName('tva')
var m = -1;
while (fab[++m]) {
fab[m].setAttribute("id", "_" + m);
};
}
function delRow() {
var current = window.event.srcElement;
//here we will delete the line
while ((current = current.parentElement) && current.tagName != "TR");
current.parentElement.removeChild(current);
}
The problem in fact is the second function that is used to make the calculation:
function calcdebours() {
var taux = document.getElementById('debours_taux_tva').value;
var ht_no_tva = document.getElementById('debours_montant_ht_no_tva').value;
var ht_tva = document.getElementById('debours_montant_ht_tva').value;
var tva = Math.round((((ht_tva) * (taux)) / 100) * 100) / 100;;
if (taux == '') {
taux = 0;
}
if (ht_no_tva == '') {
ht_no_tva = 0;
}
if (ht_tva == '') {
ht_tva = 0;
}
document.getElementById('debours_montant_tva').value = tva;
document.getElementById('debours_montant_ttc').value = (tva) + parseFloat(ht_tva) + parseFloat(ht_no_tva)
}
function
montant_debours() {
var ttc = document.getElementById('debours_montant_ttc').value;
var ttc2 = document.getElementById('debours_montant_ttc2').value;
if (ttc == '') {
var ttc = 0;
} else {
var ttc = document.getElementById('debours_montant_ttc').value;
}
if (ttc2 == '') {
var ttc2 = 0;
} else {
var ttc2 = document.getElementById('debours_montant_ttc2').value;
}
tx = parseFloat(ttc) + parseFloat(ttc2);
document.getElementById('ttc_cheque').value = Math.round(tx * 100) / 100;
}
As Id are not the same, do I have to create as many functions
there are lines?
Is it possible to fit a single function to process each line?
If so can you tell me how?
If I'm not mistaken you can use for loop and append increment to the end of element's id. Like this:
trs = document.getElementById('container Id').getElementsByTagName('tr');
For (var i = 1, i <= trs.length; i++)
{
var el = document.getElementById('debours_montant_ttc' + i);
}
