How to change multiple table rows' dates with one start date

Now, when a start date is selected in each row and click ok, an end date will display accordingly. So each table row has to manually click a button to show the end date.
Im wondering is it possible that if i only select one start date and click ok,
not only the first row end date is shown, but also 2nd , 3rd... etc rows' start date and end date will be automatically show accordingly to the interval days
PS: Please note that the number of rows are dynamic, coming from database and the total no of row is unknown.
Any ideas will be greatly appreciated. Thank you !!
(function($, window, document, undefined){
$(".addSkip").click(function() {
// row instance to use `find()` for the other input classes
var $row = $(this).closest('tr');
var date = new Date($row.find(".start_date").val()+" 0:00:00"),
days = parseInt($row.find(".days").val(), 10);
console.log(date.getDate());
console.log(days);
if (!isNaN(date.getTime())) {
date.setDate(date.getDate() + days);
$row.find(".end_date").val(date.toInputFormat());
} else {
alert("Invalid Date");
}
});
Date.prototype.toInputFormat = function() {
var yyyy = this.getFullYear().toString();
var mm = (this.getMonth()+1).toString(); // getMonth() is zero-based
var dd = this.getDate().toString();
return yyyy + "-" + (mm[1]?mm:"0"+mm[0]) + "-" + (dd[1]?dd:"0"+dd[0]); // padding
};
})

I've removed the "ok" button in favour of a simpler change event (both on date_start and days) and added the logic for your need! if something is not clear, don't esitate to ask clarifications ;)
(function($, window, document, undefined){
$('input.start_date, input.days').on('change',function() {
var $row = $(this).closest('tr'),
$start = $row.find('.start_date'),
$end = $row.find('.end_date'),
$other = $row.find('.otherfield'),
$interval = $row.find('.days'),
date = new Date($start.val()+" 0:00:00"),
days = parseInt($interval.val(), 10);
console.log(date.getDate());
console.log(days);
if (!isNaN(date.getTime())) {
date.setDate(date.getDate() + days);
$end.val(date.toInputFormat());
$other.val(date.toInputFormat());
$row.next('tr')
.find('.start_date').val(date.toInputFormat()).trigger('change');
} else {
console.log("Invalid Date");
}
});
Date.prototype.toInputFormat = function() {
var yyyy = this.getFullYear().toString();
var mm = (this.getMonth()+1).toString(); // getMonth() is zero-based
var dd = this.getDate().toString();
return yyyy + "-" + (mm[1]?mm:"0"+mm[0]) + "-" + (dd[1]?dd:"0"+dd[0]); // padding
};
})

In jquery, you can do something like this to find multiple element:
$row.find("*[class^=".end_date"]")
For more details, refer jquery selectors

But I need to calculate All Subtotal

Some issues:
If you add rows, you'll have to avoid that you get duplicate id property values in your HTML. It is probably easiest to just remove them and identify the input elements via their names, which does not have to be unique
It is bad practice to assign to a non-declared variable. Use var, and in the case of functions, you can just use the function calculate() { syntax.
Make the subtotal input elements read-only by adding the readonly attribute, otherwise the user can change the calculated total.
Instead of responding on blur events, you'll get a more responsive effect if you respond to the input event. And I would advise to bind the event handler via JavaScript, not via an HTML attribute.
I would fix some spelling errors in your elements (but maybe they make sense in your native language): Quantity with an 'a', UnitPrice without the 'e'.
You can use querySelectorAll to select elements by a CSS selector, and then Array.from to iterate over them.
See below snippet with 2 rows:
function calculate(){
var unitPrices = document.querySelectorAll('[name=UnitPrice\\[\\]]');
var quantities = document.querySelectorAll('[name=Quantity\\[\\]]');
var subTotals = document.querySelectorAll('[name=SubTotal\\[\\]]');
var grandTotal = 0;
Array.from(subTotals, function (subTotal, i) {
var price = +unitPrices[i].value * +quantities[i].value;
subTotal.value = price;
grandTotal += price;
});
// Maybe you can also display the grandTotal somehwere.
}
document.querySelector('form').addEventListener('input', calculate);
input { max-width: 7em }

How to get Addition of multiple textbox's values in another single textbox using jQuery?

Newbie in jquery, need some help with this description.
Suppose, I have 1 textbox that contain the result of Addition of another 2 textbox's.
<input type="text class="tb1">
<input type="text class="tb2">
<input type="text class="result" id="result1">
like this.
Suppose I have 5 textbox's that contain their individual 2 textbox's addition results.
Each Result textbox generate result automatically using jquery script.
So, I have 5 result textbox's with their respective addition result.
Now, I want to sum of the values in all 5 result texbox's again in another textbox when i click on checkbox automatically by using jquery or javascript script.
How can I achive this task ?
refer image for understanding of question.

Assuming that the number 5 of the text boxes remains the same here is a solution for your problem. ( Without validations )
$("#add").click(function() {
$("#result1").val(parseInt($("#box1").val()) + parseInt($("#box2").val()));
$("#result2").val(parseInt($("#box3").val()) + parseInt($("#box4").val()));
$("#result3").val(parseInt($("#box5").val()) + parseInt($("#box6").val()));
$("#result4").val(parseInt($("#box7").val()) + parseInt($("#box8").val()));
$("#result5").val(parseInt($("#box9").val()) + parseInt($("#box10").val()));
});
$( "#final-check" ).change(function() {
var finalResult = 0;
for (var i = 1; i <= 5; i++) {
finalResult = finalResult + parseInt($("#result" + i).val());
}
$("#final-result").val(finalResult);
});

Calculating Subtotals for Category Sections Using Class Names

I'm working on a project that is based on an Excel spreadsheet, where I need to calculate budgets, etc. There are various categories in my table, and I need to calculate the subtotal of each category. Here's a screenshot to make it more clear:
http://i.imgur.com/loyLbW7.png
My problem is, I'm not sure how to calculate the subtoal for each category. Right now, I have $('.subcat100 .budget').each(function(). The class "subcat100" is attached to the tr and changes for each category section (subcat100, subcat200, subcat300, etc.). The numerical value is based off the sub category number stored in database. How would I pull all of these classes and iterate through them?
jQuery:
$(document).ready(function() {
$('input[name="txtQuantity[]"],input[name="txtUnitCost[]"]').change(function(e) {
var budget = 0;
var $row = $(this).parent().parent();
var quanity = $row.find('input[name="txtQuantity[]"]').val();
var unitcost = $row.find('input[name="txtUnitCost[]"]').val();
budget = parseFloat(quanity * unitcost);
var decimal = budget.toFixed(2);
$row.find('.budget').val(decimal);
var sum = 0;
$('.subcat100 .budget').each(function() {
var budgets = $(this).val();
console.log(budgets);
if (IsNumeric(budgets)) {
sum += parseFloat(budgets, 10);
}
});
$('.subcat100 .budgetsubtotal').val(sum);
});
function IsNumeric(input) {
return (input - 0) == input && input.length > 0;
}
});

Well, I ended up doing this:
var itemcodes = <?php echo json_encode($arrItemCodes);?>;
$('input[name="txtQuantity[]"],input[name="txtUnitCost[]"]').change(function(e) {
var budget = 0;
var $row = $(this).parent().parent();
var quanity = $row.find('input[name="txtQuantity[]"]').val();
var unitcost = $row.find('input[name="txtUnitCost[]"]').val();
budget = parseFloat(quanity * unitcost);
$row.find('.budget').val(budget.toFixed(2));
$.each(itemcodes, function(intIndex, objValue) {
var sum = 0;
$('.subcat' + objValue + ' .budget').each(function() {
var budgets = $(this).val();
console.log(budgets);
if (IsNumeric(budgets)) {
sum += parseFloat(budgets, 10);
}
});
$('.subcat' + objValue + ' .budgetsubtotal').val(sum.toFixed(2));
});
});
Open to other suggestions!

Is it posible to get all the values of the text boxes with the same name?

I have a doubt in javascript. Is it posible to get the values of text boxes with the same name ?
for example
<INPUT TYPE="text" NAME="inputbox" VALUE="">
<INPUT TYPE="text" NAME="inputbox" VALUE="">
these text boxes have same name, how can i get its values by name ?
OK, lemme come to the real problem i got, hope am explaining correctly.
I have a series of text boxes which i gotta validate now. Its not a big deal to validate textboxe normally.
But this is an array of text boxes where the id of the text boxes will be available only when the fields are added dynamically by clicking on the + button. when the press button is clicked the whole set of text boxes will appear. as many times its clicked, it will get added.
So its imposible to get the values to validate with the ID, so i tried by name.

It's quite simple,
document.getElementsByName("inputBox");

You can use a multitude of different methods.
1) Manual traversal of childNodes etc, and checking for nodeName. This is pretty involved and requires a lot of boring code, so I won't write an example of that here.
2) document.getElementsByTagName. This can also be used on DOM nodes, so you can do something like document.getElementById("my_form").getElementsByTagName("input"), depending on how the rest of the DOM looks of course.
3) document.querySelectorAll("input"). The string argument is a full CSS selector. Some older browsers doesn't support this though.

Here is example for you with your code:
<div id="inputs">
<INPUT TYPE="text" NAME="inputbox" VALUE="asd">
<INPUT TYPE="text" NAME="inputbox" VALUE="efs">
</div>
<script>
$(document).ready(function () {
var howmany = $('#inputs').children("input").length;
alert(howmany);
for( i=0; i<= howmany-1; i++ ) {
var input = $("#inputs").children("input").eq(i).attr('VALUE');
alert(input);
}
});
</script>
