I want to implement a dropdown similar to the one on Booking.com in terms of functionality (I attach a screenshot), but I am encountering some issues and I can't figure out where I'm going wrong. Do you have any suggestions?
HTML
<div class="dropdown">
<input type="text" id="droptxt" class="list" readonly placeholder="Number of guests">
<div id="content" class="content">
<div class="list">
<input type="checkbox" id="rooms" class="list" value="Choose how many rooms" />
<label for="Choose how many rooms" class="list">Choose how many rooms </label>
<input type="hidden" class="list quantity" min="1" value="1" />
</div>
<div class="list">
<input type="checkbox" id="adults" class="list" value="Choose the number of adults" />
<label for="Choose the number of adults" class="list">Choose the number of adults </label>
<input type="hidden" class="list quantity" min="1" value="1" />
</div>
<div class="list">
<input type="checkbox" id="children" class="list" value="Choose the number of children" />
<label for="Choose the number of children" class="list">Choose the number of children </label>
<input type="hidden" class="list quantity" min="1" value="1" />
</div>
</div>
</div>
JavaScript
const txt = document.getElementById('droptxt');
console.log(txt);
const content = document.getElementById('content');
console.log(content);
const checkboxes = document.querySelectorAll('.list input[type="checkbox"]');
const quantity = document.querySelectorAll('.list input[type="number"]');
txt.addEventListener('click', function() {
content.classList.toggle('show');
});
// Close the dropdown if the user clicks outside of it
window.onclick = function(e) {
if (!e.target.matches('.list')) {
if (content.classList.contains('show')) content.classList.remove('show');
}
};
checkboxes.forEach(function(checkbox, index) {
checkbox.addEventListener('click', function() {
quantity[index].type = (checkbox.checked) ? 'number' : 'hidden';
calc();
});
});
quantity.forEach(function(input) {
input.addEventListener('input', calc);
});
function calc() {
let arr = [];
for (let i = 0; i < checkboxes.length; i++) {
if (checkboxes[i].checked) {
arr.push(quantity[i].value + ' x ' + checkboxes[i].value);
}
}
txt.value = arr.join(', ');
}
const quantity = document.querySelectorAll('.list input[type="number"]');
in this line you are selecting input[type="number"] but in your html there is no input which type is number. use this
const quantity = document.querySelectorAll('.list input[type="hidden"]');
it will solve your problem

I saw lots of similar question where you can extract the values of Checkboxes based on the check uncheck and add them to URL, but if we have different categories of checkbox group, separate them with &.
Example:
$(document).ready(function() {
var swapRelation = "";
$("input[type=checkbox]").click(function(e) {
var seasoning = "",
parentRelation = "",
tempArray = [];
$("input:checked").each(function() {
tempArray.push($(this).attr("name").replace(/\s/g, ''));
parentRelation = $(this).closest(".wrapper").find('.catName').text().trim();
parentRelation = parentRelation.replace(/\s/g, '');
});
if (tempArray.length !== 0) {
seasoning += `${parentRelation}=` + tempArray.toString();
// if (swapRelation == parentRelation) {
// // seasoning+=`&${parentRelation}=`+tempArray.toString();
// seasoning += `${parentRelation}=` + tempArray.toString();
// }else {
// }
//tempArray = [];
swapRelation = parentRelation;
}
console.log("example.com?" + seasoning);
});
});

Expected Result on multiple Selections:

You can use URLSearchParams to build your query string.
var usp = new URLSearchParams();
document.querySelectorAll('.wrapper').forEach((wrapperDiv)=> {
var category = wrapperDiv.querySelector('.catName').textContent;
var checkedBoxes = wrapperDiv.querySelectorAll('input[type="checkbox"]:checked');
var values = Array.from(checkedBoxes, cb=>cb.name).join('');
usp.append(category,values);
});
I'm working with HTML, JavaScript and CSS. The function objective is to create a border-radius attribute in a div element(id="surface"), and assign the value typed in inputs texts(class="chars_1") to it.
HTML
<div id="container">
<div class="input_wrapper" id="input_wrapper_tl">
<input type="text" id="input_tl" class="chars_1" value="0" onkeypress="changeSize()">
</div>
<div class="input_wrapper" id="input_wrapper_tr">
<input type="text" id="input_tr" class="chars_1" value="0" onkeypress="changeSize()">
</div>
<div class="input_wrapper" id="input_wrapper_br">
<input type="text" id="input_br" class="chars_1" value="0" onkeypress="changeSize()">
</div>
<div class="input_wrapper" id="input_wrapper_bl">
<input type="text" id="input_bl" class="chars_1" value="0" onkeypress="changeSize()">
</div>
<div id="surface">
<textarea id="code" readonly="readonly"></textarea>
<div id="options">
<input type="checkbox" checked="true" id="opt_webkit">
<label for="opt_webkit"> Webkit</label>
<input type="checkbox" checked="true" id="opt_gecko">
<label for="opt_gecko"> Gecko</label>
<input type="checkbox" checked="true" id="opt_css3">
<label for="opt_css3"> CSS3</label>
</div>
</div>
JavaScript Function
function changeSize(){
var surface = document.getElementById("surface");
var inputs = document.getElementsByClassName("chars_1");
var total = 0;
for(var x = 0; x == 3; x++){
total += Number(inputs[x].value);
}
surface.style.borderRadius = String(total)+"px";
}
First I selected both elements and assigned it to these 2 variable "surface" and "inputs". "total" being used in the "for structure" to go through every input element and select every value, and afterward convert to Number to the "total" variable.
The idea is to assign to the border-radius attribute the total variable value, which will be converted to a string so it can be recognized as a value.
Have a border
Fix the for loop for (var x = 0; x < inputs.length; x++) {
Here is an upgraded version
const changeSize = (e) => {
const tgt = e.target; // which input
if (tgt.classList.contains("chars_1")) { // ah, one of those
let total = [...document.querySelectorAll(".chars_1")].reduce(
(sum, input) => {
const val = input.value;
sum += val.trim() === "" || isNaN(val) ? 0 : +val; // only add if a number
return sum;
}, 0);
console.log(String(total) + "px")
document.getElementById("surface").style.borderRadius = String(total) + "px";
}
};
window.addEventListener("load", () => { // when page loads
document.getElementById("container").addEventListener("input", changeSize);
});
#surface {
border: 3px solid black;
}
<div id="container">
<div class="input_wrapper" id="input_wrapper_tl">
<input type="text" id="input_tl" class="chars_1" value="0">
</div>
<div class="input_wrapper" id="input_wrapper_tr">
<input type="text" id="input_tr" class="chars_1" value="0">
</div>
<div class="input_wrapper" id="input_wrapper_br">
<input type="text" id="input_br" class="chars_1" value="0">
</div>
<div class="input_wrapper " id="input_wrapper_bl ">
<input type="text" id="input_bl " class="chars_1" value="0">
</div>
<div id="surface">
<textarea id="code" readonly="readonly"></textarea>
<div id="options">
<input type="checkbox" checked="true" id="opt_webkit">
<label for="opt_webkit"> Webkit</label>
<input type="checkbox" checked="true" id="opt_gecko">
<label for="opt_gecko"> Gecko</label>
<input type="checkbox" checked="true" id="opt_css3">
<label for="opt_css3"> CSS3</label>
</div>
</div>
for(var x = 0; x == 3; x++)
that loop doesn't even execute,
change x==3 on x<3 or whatever you want to achive.
And I guess you must have border to change it's radious
I have the following HTML:
<div class="filters">
<div class="filter-label">6</div>
<div class="filter-inputs">
<input type="number" name="i1" id="i1" value="1" min="0" step="1" />
<input type="number" name="i2" id="i2" value="2" min="0" step="1" />
<input type="number" name="i3" id="i3" value="3" min="0" step="1" />
</div>
</div>
The question:
I'd like to, when any input is changed, I want to get that value and
the value of the other two text boxes and add them all together. Once
I have the total value, I need to then change the text of the label
with the new value.
I also have the following JavaScript (jQuery) to detect when a change has happened, but after that, I can't figure out how to loop through each input in the div and get the value.
$('.filter .filter-inputs input').on('input', function() {
var element = $(this);
// ...
});
I looked at loops like the jQuery each method but I've got no idea how to loop through each input inside the filter-inputs div.
You could create array from inputs using map and get methods and then calculate sum with reduce method.
let inputs = $('.filters input');
let label = $('.filter-label');
inputs.on('input', function() {
let sum = inputs.map(function() {
return $(this).val()
}).get().reduce((r, e) => r + +e, 0);
label.text(sum)
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="filters">
<div class="filter-label">6</div>
<div class="filter-inputs">
<input type="number" name="i1" id="i1" value="1" min="0" step="1" />
<input type="number" name="i2" id="i2" value="2" min="0" step="1" />
<input type="number" name="i3" id="i3" value="3" min="0" step="1" />
</div>
</div>
Or you could just create array with Array.from method and then use reduce method to sum values.
let inputs = $('.filters input');
let label = $('.filter-label');
inputs.on('input', function() {
label.text(Array.from(inputs).reduce((r, {value}) => r + +value, 0))
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="filters">
<div class="filter-label">6</div>
<div class="filter-inputs">
<input type="number" name="i1" id="i1" value="1" min="0" step="1" />
<input type="number" name="i2" id="i2" value="2" min="0" step="1" />
<input type="number" name="i3" id="i3" value="3" min="0" step="1" />
</div>
</div>
Use this script
$('.filter-inputs input').change(function(){
var total = 0;
$('.filter-inputs input').each(function(){
total += parseInt($(this).val());
});
$('.filter-label').html(total);
});
No problem!
$('.filter .filter-inputs input').on('input', function() {
//not needed:
//var element = $(this);
// Obtain numeric entries
var i1 = Number($("#i1").val());
var i2 = Number($("#i2").val());
var i3 = Number($("#i3").val());
// Calculate sum of entries
var total = i1 + i2 + i3;
// Populate label div with sum
$(".filter-label").html(String(total));
});
Good luck!
You don't need jQuery for this task http://jsfiddle.net/72e3jLc0/
let label = document.querySelector('.filter-label');
let inputs = document.querySelectorAll('.filter-inputs input');
inputs.forEach(input => {
input.addEventListener('change', e => {
label.innerText = parseInt(label.innerText) + parseInt(input.value);
});
});
Try using the following approach:
$(document).ready(function() {
var total=0;
$("input[type='number']").change(function() {
$(".results").html("");
var objects = $(".filters").find("input[type='number']");
for (var i = 0; i < objects.length; i++) {
total += parseInt($(objects[i]).val());
}
$(".filter-label").text(total);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="filters">
<div class="filter-label">6</div>
<div class="filter-inputs">
<input type="number" name="i1" id="i1" value="1" min="0" step="1" />
<input type="number" name="i2" id="i2" value="2" min="0" step="1" />
<input type="number" name="i3" id="i3" value="3" min="0" step="1" />
</div>
</div>
I know this is an old thread, but I would like to give my contribution.
The id can be replaced with document or "body", and input is not necessary if all your inputs have the class .form-control.
$("#id-of-overall-div-element").on("change", "input, .form-control", function () {
// Do something
});
I have more than 10 section that included three inputs in each section as follows:
<div class="product_quantity">
<div class="color-quantity">
<input onkeydown="return myFunction(event);" name="custom_small" class="custom_small" type="text">
<input onkeydown="return myFunction(event);" name="custom_medium" class="custom_medium" type="text">
<input onkeydown="return myFunction(event);" name="custom_large" class="custom_large" type="text">
</div>
<div class="color-quantity">
<input onkeydown="return myFunction(event);" name="white_small" class="custom_small" type="text">
<input onkeydown="return myFunction(event);" name="white_medium" class="custom_medium" type="text">
<input onkeydown="return myFunction(event);" name="white_large" class="custom_large" type="text">
</div>
</div>
I am calculating the product quantity from each section but its giving me the whole amount of products on the basis of amount entered in every input. but i want the amount of products in section separately
I am using jQuery to do so please check the code and recommend the changes as required:
jQuery(".color-quantity input").each(function () {
if (this.value) {
quantity += (this.value) * 1;
classname = jQuery(this).attr('class');
arr.push(classname);
}
if (quantity == '') {
quantity = 0;
}
});
You can get total off each section as an array like following.
var arr = $('.color-quantity').map(function () {
var total = 0;
$('input', this).each(function () {
total += this.value * 1;
});
//do some stuff
if (total < 50) {
$('.btn-cart').removeAttr("onclick");
}
return total;
}).get();
console.log(arr)
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="color-quantity">
<input type="text" value="1">
<input type="text" value="2">
<input type="text" value="3">
</div>
<div class="color-quantity">
<input type="text" value="4">
<input type="text" value="5">
<input type="text" value="6">
</div>
You might try a nested loop. first loop through the color-quantity divs, then through the inputs. like this:
jQuery(".color-quantity").each(function () {
var quantity = 0;
$(this).find('input').each(function() {
if (this.value) {
quantity += (this.value) * 1;
classname = jQuery(this).attr('class');
arr.push(classname);
}
if (quantity == '') {
quantity = 0;
}
});
// here is where you can get the total value for each div
});
I'm trying to sum the value of an input text changing dynamically with a radio that also changes dynamically. I'm doing something right but also something wrong because it doesn't sum when I want. The sum should show everytime the input text changes and not randomly disappear then you click a radio, just sum them.
the fiddle http://jsfiddle.net/7tFhx/
and the code
<form id="myForm" accept-charset="UTF-8">
<button type="button" class="btn-tt btn-primary btn-lg" disabled>1. Elige el color</button></br>

<input class="calc" id="fb1" type="radio" name="fb" value="10">

<img src="img/02.jpg"/>
</label>
<div>
Total: <span id="price">0</span>€
</div>
</form>
js:
$(function(){
var mecanismoMedida = ['100','200'];
var mecanismoPrecio = ['50','80'];
$('#ancho').on('input',function(){
var j = 1, i = 0;
value = parseInt(($("#ancho").val() / 8) + 1);
for(i = 0; i < mecanismoMedida.length; i++){
if($("#ancho").val() >= mecanismoMedida[i] && $("#ancho").val() <
mecanismoMedida[j]){
value += mecanismoPrecio[i];
break;
} else {
j++;
}
}
$("#price").text(this.value + value);
});
$('#myForm input[type="radio"]').on('change', function () {
var sum = 0;
$("#myForm").find("input[type='radio']:checked").each(function () {
sum += parseInt(this.value);
});
$("#price").text(sum);
});
});
If it's a simple sum you're after, you can simply run an update code on the keyup and change events of all input elements:
$("input").change(function(){update();}).keyup(function(){update();});
To update them, first you need to check and see which one of the two radio buttons are checked and get its value:
function update(){
var p = 0;
for(var i = 0; i < $(".calc").val(); i++)
{
if($($(".calc")[i]).prop("checked") == true)
{
p += parseInt($($(".calc")[i]).val());
}
}
After that, simply parse the values of the textboxes to integers and add them to the value of the radio button. I created a custom function to do this, because if the boxes are empty, parsing them returns NaN:
p = parseInt(p);
p += parseInt(val2($("#ancho")));
p += parseInt(val2($("#alto")));
p += parseInt(val2($("#cantidad")));
p = parseInt(p);
$("#price").html(p);
}
function val2(elm){
if(isNaN(parseInt($(elm).val())))
return 0;
else
return parseInt($(elm).val());
}
