Using jQuery, I have float values in fields with similar class names "score"and I just want to make a function that will add all float values in those fields and assign the result to "field5".
<input id="field1" type="text" class="score">2.5</input>
<input id="field2" type="text" class="score">6.02</input>
<input id="field3" type="text" class="score">1</input>
<input id="field4" type="text" class="score">4.03</input>
<input id="result" type="text" class="result"></input>
I made the script below but it doesn't work even though the function executes.
$(.score).on('change',function(){
var total = 0
$(this).each(function(){
total += this.value;
});
});
$('#result').val(total);
});
Lot of issues in your code:
JS:
$(".score").on('keyup', function () {
var total = 0
$(".score").each(function () {
total += parseFloat(this.value);
});
$('#result').val(total);
});
HTML
<input id="field1" type="text" class="score" value="1"/>
<input id="field2" type="text" class="score" value="1.2"/>
<input id="field3" type="text" class="score" value="1.4"/>
<input id="field4" type="text" class="score" value="3.1"/>
<input id="result" type="text" class="result" value=""/>
Demo: http://jsfiddle.net/GCu2D/839/
input is a self closing tag. You should use it like in this example
You should iterate on $(".score") instead of $(this) to get all input values. Latter will give only the current input's value.
Use parseFloat to convert the string type into float. By default you get string value from the .value. In order to add them, you need to convert them to float
Your selector $(.score) is invalid. Use $(".score") .
$('#result').val(total); should be inside the event handler.
First of all, I believe .change() is used with dropdowns. Try using .keydown() to detect a change in an input box.
There are a few errors in your code -
var total = 0;
Semicolon is missing.
$('#result').val(total);
This will assign the value and will not show it. If you wish to display teh value as well, use
$('#result').append(total);
$(document).ready(function(){
$(".score").on('change',function(){
var total = 0.00;
$(".score").each(function(){
if(undefined != $(this).val() && "" != $.trim($(this).val()))
total += parseFloat($(this).val());
});
$('#result').val(total);
});
});
I finally figured it out. Thanks guys!
function getResult(){
var total = 0;
$('.score').each(function(){
var checkval= parseFloat(this.value);
if(!isNaN(checkval)) total += checkval;
});
$('#result').val(total.toFixed(2));
}

I have inputs with class="amount". The # of inputs is dynamically controlled by the user - but I doubt that is important. I then have an input with id="total"
<form>
<input class="amount">
<input class="amount">
<input class="amount">
<input id="total">
</form>
I would like to sum the values in the inputs with .amount and place that sum with #total. I would like for this calculation to occur as changes happen in any of the ".amount" inputs. I am quite new to the use of JS and I am struggling with the cleanest way to approach solving this use case.
Thanks!
UPDATED ANSWER : You can check by running the snippet here.
$('.amount').on("input", function() {
let total = 0;
$('.amount').each(function() {
total += $(this).val()/1;
})
$('#total').val(total);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form>
<input class="amount" placeholder="One"><br/>
<input class="amount" placeholder="Two"><br/>
<input class="amount" placeholder="Three"><br/>
<input id="total" placeholder="Total" readonly>
</form>
HTML
<form id="form_input">
<input class="amount">
<input class="amount">
<input class="amount">
<input id="total">
</form>
Use following Step in j query
$(document).ready(function () {
$('#form_input').on("keyup", ".amount", function () {
var sum = 0;
$('.amount').each(function () {
sum += Number($(this).val());
});
$('#total').val(sum);
});
});
Then use this code in your delete row function
$(wrapper).on("click", ".remove_field", function(e) {
e.preventDefault();
$(this).closest('tr').remove();
i--;
var sum = 0;
$('.item_price').each(function () {
sum += Number($(this).val());
});
$('#Item_total_price').html(sum);
console.log(sum);
});

Using Jquery I need to add all values of input.
Using jquery each is there any way to use regix in element name
like
items[regix_goes_here][debit]
I need values of all input and I want them incremented using each.
My code
<input name="items[1][debit]" type="number">
<input name="items[341][debit]" type="number">
<input name="items[31][debit]" type="number">
<input name="items[431][debit]" type="number">
First, assign a class to your inputs, for example:
<input class="js-inc" name="items[1][debit]" type="number">
<input class="js-inc" name="items[341][debit]" type="number">
<input class="js-inc" name="items[31][debit]" type="number">
<input class="js-inc" name="items[431][debit]" type="number">
Now you can increment all of them, without even jquery. Use .value to access the value as a string. Use Number("..") to convert it to a number. Add one to it, and assign it back.
var inputs = document.querySelectorAll("input.js-inc")
inputs.forEach(function(input) {
input.value = Number(input.value) + 1
})
Here's a live example
If you want to sum all the values of inputs with name="items[X][Y]", you can filter them by testing if their name attribute matches this /items\[\d+\]\[debit\]/ Regex.
This is how should be your code:
var sum = 0;
$('input[type="button"]').click(function() {
$('input').each(function() {
if ($(this).attr('name') && $(this).attr('name').match(/items\[\d+\]\[debit\]/)) {
sum += $(this).val() ? parseInt($(this).val()) : 0;
}
});
console.log(sum);
});
Demo:
var sum = 0;
$('input[type="button"]').click(function() {
$('input').each(function() {
if ($(this).attr('name') && $(this).attr('name').match(/items\[\d+\]\[debit\]/)) {
sum += $(this).val() ? parseInt($(this).val()) : 0;
}
});
console.log(sum);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input name="items[1][debit]" type="number" value="2">
<input name="items[341][debit]" type="number" value="2">
<input name="items[31][debit]" type="number" value="2">
<input name="items[431][debit]" type="number" value="2">
<input type="button" value="SUM" />
I'm trying to do a simple calculation onblur with arrays but it's not firing. If I change it to a span or div it works fine. Why isn't it working with an input field?
I need it to be an input field because it's easier to store the values in a database.
<input type="text" class="input-small" name="partnumber[]">
<input type="text" class="input-small" name="partdescription[]" >
<input type="text" class="input-small" name="partprice[]" onblur="doCalc(); calculate(); ">
<input type="text" class="input-small" name="partquantity[]" onblur="doCalc(); calculate(); ">
<input type="text" readonly class="input-small parttotal" name="parttotal[]" >
Calculation
function doCalc() {
var total = 0;
$('tr').each(function() {
$(this).find('.parttotal').html($('input:eq(2)', this).val() * $('input:eq(3)', this).val());
});
$('.parttotal').each(function() {
total += parseInt($(this).text(),10);
});
}
Firstly, I wouldn't use inline events.. Here I've used delegated events, an advantage here if you dynamically add any more lines, it will still work..
Next make sure each line has some sort of wrapper for each line, here I've used a simple DIV. Yousr might be your TR..
The rest then becomes easy, as can be seen here, this example I've just included the price, qty & total, and done 2 lines for testing..
function calc() {
var h = $(this).closest('div');
var qty = h.find('[name="partquantity[]"]');
var price = h.find('[name="partprice[]"]');
var total = h.find('[name="parttotal[]"]');
total.val(qty.val() * price.val());
}
$('body').on('blur', '[name="partprice[]"],[name="partquantity[]"]', calc);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>
<input type="text" class="input-small" name="partprice[]">
<input type="text" class="input-small" name="partquantity[]">
<input type="text" readonly class="input-small parttotal" name="parttotal[]" >
</div>
<div>
<input type="text" class="input-small" name="partprice[]">
<input type="text" class="input-small" name="partquantity[]">
<input type="text" readonly class="input-small parttotal" name="parttotal[]" >
</div>
you can't use .html() to set the value of a textbox.
Change this line:
$(this).find('.parttotal').html($('input:eq(2)', this).val() * $('input:eq(3)', this).val());
to
$(this).find('.parttotal').val($('input:eq(2)', this).val() * $('input:eq(3)', this).val());
Note the change ('.parttotal').html becomes ('.parttotal').val
I was trying to solve another person's jQuery question and ran into an issue of my own.
In order to solve this question, I need to determine the number of text boxes that are empty. I thought the best solution would be to use the element[attribute='value'] selector but that didn't work.
alert($("input[val='']").length);
I always get 0, even when there are 3 other empty text boxes. Empty text boxes should have a value equal to an empty string.
Here is my fiddle
http://jsfiddle.net/04gqaLog/
HTML
<input type="text" /></br>
<input type="text" /></br>
<input type="text" /></br>
<input type="text" />
jQuery
$(document).ready(function() {
var sum = 0;
var boxesFilled = 0;
$("input").on("change", function() {
sum += +$(this).val();
boxesFilled += 1;
alert($("input[val='']").length);
});
});
The first issue is you are referring to the value attribute as val. Those are considered two distinct attributes.
The next issue is some input elements may not have a value attribute. Therefore, you will need to specifically check for that or check if the value is falsey
var emptyInputs = $('input').filter(function() {
return !$(this).val();
});
console.log(emptyInputs.length);
$(document).ready(function() {
var sum = 0;
var boxesFilled = 0;
$("input").on("change", function() {
sum += +$(this).val();
boxesFilled += 1;
var emptyInputs = $('input').filter(function() {
return !$(this).val();
});
console.log(emptyInputs.length);
});
});

Here i have problem with my code that i need to calculate multiply the first two textboxes. and that result will be appear into the last one, i mean third textbox as TotalAmount. Could you help me? here three textboxes appeared in single row with add button. when i submit the add button new created with three boxes again. I need to finish it in jquery of java script. please help me guys
First of all, remove the array-declaration, you're not using the the input fields as arrays. they are single values.
<INPUT name="Qty" id="Qty" type="text" class="south" />
<INPUT name="Amount" id="Amount" type="text" class="south"/>
<INPUT name="TotalAmount" id="TotalAmount" type="text" class="south" disabled="disabled"/>
And the jquery.
$(document).ready(function(){
qty = $("#Qty").val();
amount = $("Amount").val();
$("#Qty, #Amount").keyup(function(){
$("#TotalAmount").val((qty)*(amount));
});
});
Here is your JavaScript:
$(document).ready(function () {
var $quantity = $('#Qty\\[\\]'),
$amount = $('#Amount\\[\\]'),
$total = $('#TotalAmount\\[\\]'),
quantity,
amount;
$($quantity.add($amount)).keyup(function () {
quantity = Number($quantity.val().replace(/[^0-9,.]/g, ''));
amount = Number($amount.val().replace(/[^0-9,.]/g, ''));
$total.val(quantity * amount);
});
});
UPDATE Changed to keep the DOM ids the same in case they have to be that way. For an unmentioned reason as mentioned by #Ken Keenan.
