How to to use an output result in a new calculation? - javascript

I have a code with two calculations
x = a * b * e
and the sum from it (x) shall be added together with c and d
y = c + d + x
how do I do that? The other code I succeeded with, but not to get the sum of X to be added together with C and D
my code looks like below
<form oninput="x.value=(parseFloat(a.value.replace(',','.'))*parseFloat(b.value.replace(',','.'))*parseFloat(e.value.replace(',','.'))).toFixed(2).toString().replace(/\B(?<!\.\d*)(?=(\d{3})+(?!\d))/g, ' ').replace(/[.]/,',');y.value=(parseFloat(c.value.replace(',','.'))+parseFloat(d.value.replace(',','.'))+parseFloat(x.value.replace(',','.'))).toFixed(2).toString().replace(/\B(?<!\.\d*)(?=(\d{3})+(?!\d))/g, ' ').replace(/[.]/,',')">
<table>

javascript: Auto calculate price upon entering quantity in input box

In my program I am trying to auto calculate total price when user enter quantity in input box. For that I performed below script. but due to some error my script doesn't working as per expectation and when I enter quantity, total price doesn't get updated. Can anyone tell me what's wrong in my code. I want to perform this script without jquery.
code:
<!DOCTYPE html>
<html>
<head>
<title>form</title>
</head>
<body>
<form action="" method="POST" name="myForm" id="myForm">
<table bgcolor="pink" align="center" border="2px">

</form>
<script>
function calculate() {
var f = document.forms['myForm'];
for(var i=0;i<4;i++){
var qty = document.getElementByName('qty'+i);
document.getElementById('total'+i).value = newValue;
}
}
</script>
</body>
</html>
There is no document.getElementsById, you should name your different quantities and total price fields with distinct names and traverse thru them using document.getElementById('qty'+i);

in above jsfiddle all ENTER SANCTIONED SEATS sum will not be greater then "Enter total number of sanctioned seats" in onchange.
You need to use jquery keyup event as I mentioned in fiddle.
Please check this fiddle
Here I just made textbox value blank if sum of three sanctioned seats are greater than total.
Also i have cleare 3 textbox if you chane total textbox
Open this link : https://jsfiddle.net/5y6na3wr/7/
$(document).ready(function(){
$(".seats").on('keyup',function(){
var total = parseInt(0) ;
$( ".seats" ).each(function( index ) {
if($(this).val()){
total = total + parseInt($(this).val());
}
});
if(total > $("#sanctionedSeatsSummary").val()){
alert("total sanctioned Seats are greater then given sanctioned Seats");
}
});

You can target the form using id and add remove class to show hide the form.
<style>
.hidden {
display:none;}
</style>
<script type="text/javascript">
function showHide() {
var hiddeninput = document.getElementById("form1");
if (hiddeninput.classList.contains("hidden")) {
hiddeninput.classList.remove("hidden");
}
else {
hiddeninput.classList.add("hidden");
}
}
</script>
Given that you're hiding the element with a class, you can show and hide it by removing and re-adding the class. The classList.toggle method* will do that:
function hide(id) {
var el = document.getElementById(id);
if (el && el.classList) {
el.classList.toggle('hidden');
}
}
<style type="text/css">
.hidden {
display: none;
}
</style>
<body>
<input id="foo"><br>
<button onclick="hide('foo')">Hide input</button>
</body>
* Note that the reference to MDN includes a polyfill for Element.classList to support older browsers.
how about this... ??
function showHide() {
var button = document.getElementById("butt");
var hiddeninput = document.getElementsByClassName("hidden");
var form1 = document.getElementById("form1");
if (form1 && form1.style.display=="none") {
form1.style.display = "block";
} else {
form1.style.display = "none";

You can use jQuery for that.
For hiding do that in the onClick event on the button.
$( ".target" ).hide();
For showing
$( ".target" ).show();

Generate Array of numbers from sudoku table HTML table

I have a simple HTML table setup to look like a sudoku board. Each cell is a input with type = number.
I want to use jQuery to extract all of the numbers from each cell and generate an array of arrays. The array will be formatted like this:
array = [ [1,2,3,4,5,6,7,8,9],
[2,3,4,5,6,7,8,9,1],
[3,4,5,6,7,8,9,1,2],
[1,2,3,4,5,6,7,8,9],
[2,3,4,5,6,7,8,9,1],
[3,4,5,6,7,8,9,1,2],
[1,2,3,4,5,6,7,8,9],
[2,3,4,5,6,7,8,9,1],
[3,4,5,6,7,8,9,1,2]]
Here is a fiddle of my general set up: Sudoku Board Fiddle
the css is taken from this answer sudoku css
Essentially the HTML is set up like this:
<table id='#table'>
<tr id="row1">
<td>
<input type="number" /> </td>
<td>
<input type="number" /> </td>
<td>
<input type="number" /> </td>
<td>
<input type="number" /> </td>
<td>
<input type="number" /> </td>
<td>
<input type="number" /> </td>
<td>
<input type="number" /> </td>
<td>
<input type="number" /> </td>
<td>
<input type="number" /> </td>
</tr>
.... x9 rows
</form>
I want to make a function with jQuery that on the click of a button, it converts each row into an array and puts each array into one array.
My approach:
Use jQuery to select the table. Loop through each table row. Nest a loop to loop over each input and append each value to arrays.
This is what I have so far (it does not work at all. It just logs an empty array, even if I populate the table with values).
var array = [];
$('button').on('click', function(){
event.preventDefault();
$('table').children('tr').each(function(){
$(this).find('input').each(function(){
array.push($(this).val());
});
});
alert(array);
});
You should have another array for each tr and after all td iterations, push that array in main array
Fiddle here
$('button').on('click', function() {
event.preventDefault();
var array = [];
$('#table').find('tr').each(function() {
var arr = [];
$(this).find('input').each(function() {

<button>Generate Array</button>
There are a couple of problems with your code. First, you're trying to find an element with the ID table (that's what #table targets). You don't have an element with the ID of table, so that instantly doesn't work. So you either need to give you table an ID, or change your selector to get the table. I'll suggest the latter, for now.
$('table')...
Secondly, instead of using .children(), try using the $(selector, parent) shorthand. .children() is awkward in the case of tables; it only selects direct children, and a TR is not a direct child (tbody is the direct child, even if you don't declare it in your markup). I avoid using .children(). If anything, use .find().
$('tr', 'table').each(function() { ... });
Thirdly, you are using event.preventDefault(), but you haven't passed the event paramter to your callback. You need to pass the event, like so:
$('tr', 'table').each(function(event) { ... });
You will still only end up with a 1-dimensional array, not a 2-d array like you'd require, but this fixes the problems you had with your initial code.
First point is, you haven't added id for table element. But you are taking reference of table id in function.That is how it was in fiddle code.
JS Code:
var array = [];
$('button').on('click', function(){
// event.preventDefault();
$('#table').find('tr').each(function(){
var newarr=[];
$(this).find('td input').each(function(){
newarr.push($(this).val());
console.log('newarr:'+newarr);
});
array.push(newarr);
});
console.log(array);
});
I have updated and code and the final result is printing in console.
Check it.
var array = [];
$('button').on('click', function(){
event.preventDefault();
array = [];
$('#table').find("tr").each(function(){
var row = [];
$(this).find('input').each(function(){
row.push($(this).val());
});
array.push(row);
});
console.log(array);
});
