Make static functions to be dynamic - javascript

I am doing an exercise to learn JavaScript. I am having issues making my program dynamic. What I want to do here is:
Create two input to let the user set up the new product data.
Create a button. This button will have assigned a click event that will: 1- Get the data from the inputs. 2- Create a new product row with the data we stored.
Be able to delete all items and decrease total price based on the price of reminding item. In case there is no item, total price should be 0.

JS:
// qty
function getQty() {
var qty = document.querySelector("#qty").value;
document.querySelector("#total").innerHTML = qty;
return qty;
}
getQty();
// qty2
function getQty2() {
var qty2 = document.querySelector("#qty2").value;
document.querySelector("#total2").innerHTML = qty2;
return qty2;
}
getQty();
// Price
function getPrice() {
var price = parseInt(document.querySelector("#product").innerHTML);
document.querySelector("#total").innerHTML = price * getQty();
}
getPrice();
// Price 2
function getPrice2() {
var price2 = parseInt(document.querySelector("#product2").innerHTML);
document.querySelector("#total2").innerHTML = price2 * getQty2();
}
getPrice2();
// total Price
function totalPrice2() {
var total = parseInt(document.querySelector("#total").innerHTML);
var total2 = parseInt(document.querySelector("#total2").innerHTML);
document.querySelector("#totalPrice").innerHTML = total + total2;
}
totalPrice2();
//Romove Item
function removeItem() {
var remove = document.querySelector("#itemSubject").remove("itemSubject");
// setTimeout(function() { alert("Your shopping cart is empty"); }, 1000);
}
removeItem();
function removeItem2() {
var remove = document.querySelector("#itemSubject2").remove("itemSubject2");
// setTimeout(function() { alert("Your shopping cart is empty"); }, 1000);
}
removeItem2();

For your getPrice() and getPrice2() functions, we can make them dynamic by changing the following:
var price = parseInt(document.querySelector("#product").innerHTML);
and
var price2 = parseInt(document.querySelector("#product2").innerHTML);
These lines looks for elements with static names, instead we should give all inputs a common class name and loop through them. That way, we don't have to rely on static element IDs. For example, if we gave each input the class 'quantityinput', we can do the following:
var elements = document.getElementsByClassName("quantityinput");
for(var i=0; i<elements.length; i++) {
// Select this element and get its quantity
var this_total = elements[i].value;
// Get the price for this element by selecting the price td, then its second child
var this_price = elements[i].parentElement.parentElement.parentElement.previousSibling.childNodes[2].value;
// Select the total label for this row
var this_total_label = elements[i].parentElement.parentElement.parentElement.childNodes[1];
// Now update the total label for this row by multiplying the price and the quantity
this_total_label.value = this_total * this_price;
}
Now we don't have to worry about a certain row missing, since we iterate through all existing rows. A similar approach can be taken when calculating the total price for all rows, just loop through each rows total price, add them together then assign the total to the total price label.

jQuery validation on dynamic table form not working on using blur

I am creating form dynamically which has n rows (coming from array having n elements). Form fields have two type of columns (text & number) which I have given different id.
Although JQuery validation is working but "validate parts button" is not responding correctly. From the code condition it should not be enabled in case text is not valid.
Thanks..!

Get value from an input with Jquery

I have found a lot of answers to this type of question but none are solving the problem.
I even have a very similar piece of code that works. However, this keeps giving a NaN. I have narrowed it down to not being able to get the value of
var or = parseFloat($(this).siblings("input[name='or']").val());
Here is what I have.
Any help is greatly appreciated!
<tbody>

With the guidance from Tyler Roper it was a simple fix having nothing to do with Javascript.
I was tired and testing things and tried to quickly convert a page into a table.
The terrible HTML was the cause. To fix it I simply changed to:
<form action="/weekly_reports/" method="POST">
<table id="office_weekly" class="table table-hover table-striped">
<thead>
<th>Office</th>
<th>Backpacks</th>
<th>Hotlines</th>
<th>Total</th>
</thead>
<tbody>
{% for i in t %}
<tr class="hotlines">
<td><strong>{{i.owner}}</strong><br>{{i.owner_id}}</td>
<td>
{{i.tot_itm}}<br>
Per Piece Profit: {{"${:,.2f}".format(i.item_prof)}}
</td>
<td>
Payable Hotlines <br><input type="text" name="hln" maxlength="4" value=""><br>
Per Hotline Profit: {{"${:,.2f}".format(i.hotline_prof)}}<br>
<input type="hidden" name="or" value="{{i.hotline_prof}}">
</td>
<td>
Total Backpack Profit: {{"${:,.2f}".format(i.tot_prof)}}
</td>
<td>Total Hotline Profit: <input type="text" name="hlnt" readonly /></td>
</tr>
{% endfor %}
<td><button type="submit" class="btn btn-link btn-xs btn-block">Submit Report</button></td>

best approach in adding a comma to a number like 123,456.78 in jquery

found this solution in this solution
function commaSeparateNumber(val){
while (/(\d+)(\d{3})/.test(val.toString())){
val = val.toString().replace(/(\d+)(\d{3})/, '$1'+','+'$2');
}
return val;
}
in this link add commas to a number in jQuery
I am trying to apply it in my project. it works in one column but it doesn't work in price and sub total
function commaSeparateNumber(val){
while (/(\d+)(\d{3})/.test(val.toString())){
val = val.toString().replace(/(\d+)(\d{3})/, '$1'+','+'$2');
}
return val;
}

Thank you so much in advance!
The problem is that parseFloat fails to correctly parse the value from the total cost textbox because it contains one or more ,. You need to remove the , from the string before parsing to float. You can remove any ,'s by calling .replace(/,/g,'') on the textbox value in the calculateSubTotal function.
It seems that for some values the function commaSeparateNumber doesn't work as expected. I removed it from the snippet below and replaced it with toLocaleString() which takes parameters for locale and minimum/maximum fraction digits .toLocalString("en-US", { maximumFractionDigits: 2}). Set the locale to one you know uses , to separate thousands. If you know that won't be an issue you can pass undefined for the locale.
Your snippet has been updated below:
var rowCount = 1;
$('#add').click(function() {
rowCount++;
$('#orders').append('<tr id="row'+rowCount+'"><td><input class="form-control product_price" type="number" data-type="product_price" id="product_price_'+rowCount+'" name="product_price[]" for="'+rowCount+'"/></td><input class="form-control" type="hidden" data-type="product_id" id="product_id_'+rowCount+'" name="product_id[]" for="'+rowCount+'"/><td><input class="form-control quantity" type="number" class="quantity" id="quantity_'+rowCount+'" name="quantity[]" for="'+rowCount+'"/> </td><td><input class="form-control total_cost" type="text" id="total_cost_'+rowCount+'" name="total_cost[]" for="'+rowCount+'" readonly/> </td><td><button type="button" name="remove" id="'+rowCount+'" class="btn btn-danger btn_remove cicle">-</button></td></tr>');
});
// Add a generic event listener for any change on quantity or price classed inputs

getTotalCost($(this).attr("for"));

var button_id = $(this).attr('id');
$('#row'+button_id+'').remove();
});
// Using a new index rather than your global variable i
function getTotalCost(ind) {
var qty = $('#quantity_'+ind).val();
var price = $('#product_price_'+ind).val();
var totNumber = (qty * price);
// .toLocaleString
var tot = totNumber.toLocaleString("en-US", { maximumFractionDigits: 2});
$('#total_cost_'+ind).val(tot);
calculateSubTotal();
}
function calculateSubTotal() {

How can validation be done after using the clone function in JavaScript?

I used JavaScript to clone and add rows. How can separate validation be done for each row?
var i = 0;
function cloneRow() {
var row = document.getElementById("clone");
var table = document.getElementById("data");
var selectIndex = 1;
var clone = row.cloneNode(true);
table.appendChild(clone);
clone.setAttribute("style", "");
}
function deleteRow(btn) {
var result = confirm("Do you Want to delete this ?");
if (result) {
var row = btn.parentNode.parentNode;
row.parentNode.removeChild(row);
}
}

I'd like to create this type of validation for every row or <tr>.
When the add button is clicked a new input is dynamically added. However when the form is submitted only the first input field is validated. How can I validate the dynamically added inputs?
If you want to separate the validation for each row - you should create a row constructor.
Basically when you clone a new row - you clone the constructor with all its methods inside.
var Row = function () {
this.name = "";
this.value = "";
//add more properties
}
Create the methods:
Row.prototype.verify = function () {
return this.name !== `undefined` && this.value !== `undefined`;
}
In your clone function you just have to call it:
var rowInstance = new Row();
And you can use it like that:
if (rowInstance.verify()) {
//if the row information is valid then do something
}

How to sum all array values using Angular

I am creating a dynamic form list and in row there is a subtotal value and what I need is to have a grand total. But my problem is I can't sum all the values.
Here's a bit of my code:
//i created a array that will hold all subtotals
$scope.grand_total = [];
//this function is visible in every row
$scope.subTotal = function($index) {
var total = 0;
angular.forEach($scope.quoteHeader.items[$index], function(value){
angular.forEach(value.items, function(v) {
total += v.unit * v.unit_price;
$scope.grand_total.push({
subtotal: total
});
});
});
return total;
}
//this will process the sum but It didn't work
function computeGrandTotal() {
var total = 0;
angular.forEach($scope.grand_total, function(value) {
console.log(value);
});
}
$scope.grandTotal = function() {
var total = 0.00;
computeGrandTotal(); //call the subtotal function
console.log(computeGrandTotal());
return total;
}

I hope you can help me with this. Thats all thanks :)
You need to store the total at the given index in the sub_total array then
var quotationList = angular.module('quotation_list', []);
quotationList.controller('quoteList', function($scope) {
$scope.quoteHeader = {};
$scope.quoteHeader = {
items: []
}
$scope.json_output = angular.fromJson($scope.quoteHeader); //display json view
$scope.addParticularHeader = function() {
$scope.quoteHeader.items.push({
particular_name: 'SAMPLE PARTICULAR TITLE',
child_label: {
items: []
}
});
}
$scope.removeQuoteHeader = function($index) {
$scope.quoteHeader.items.splice($index, 1);
}
$scope.addParent = function($index) {
//here we will append the new row
//console.log($scope.quoteHeader.items[$index].child_label);
$scope.quoteHeader.items[$index].child_label.items.push({
particular: 'Sample Particular Name',
unit: 1,
unit_label: 'sqm',
unit_price: 0.00,
unit_subtotal: 0.00,
sublevel: {
items: []
}
});
}
$scope.removeParent = function(parent_id, $index) {
$scope.quoteHeader.items[parent_id].child_label.items.splice($index, 1);
}
$scope.addSubLevel = function(parent_id) {
console.log(parent_id);
}
$scope.grand_total = [];
$scope.subTotal = function($index) {
var total = 0;
angular.forEach($scope.quoteHeader.items[$index], function(value) {
angular.forEach(value.items, function(v) {
total += v.unit * v.unit_price;
});
});
$scope.grand_total[$index] = total;
return total;
}
function computeGrandTotal() {
var total = 0;
//console.log($scope.grand_total);
angular.forEach($scope.grand_total, function(value) {
console.log('total', value);
total += value;
});
return total;
}
$scope.grandTotal = function() {
return computeGrandTotal();
}
});
