What is wrong with this MDC range slider element?

What is wrong with this MDC range slider element? - javascript

The second slider (for the end of the range) does not work as expected. See the output in the console.
This code is more or less just a copy from https://m2.material.io/components/sliders/web#sliders and I have no idea what is wrong. So I would be grateful if someone could spot the error.
Here is the error I see in the console with the original file:

JavaScript is not working for another JavaScripted input fields

I am trying to auto sum input fields using JavaScript in a web page. My javascript function is partially working. However .change is triggered when it is manually changed but not if it is changed by another JavaScript function. How can I triggered it even when it is not manually change?

Kindly help me to find out the mistake or suggest a better solution.

The main issue is because setting the value of an input programmatically does not raise an event in the DOM - so your change event handler on the total fields in the last section never runs.
To correct this you can use jQuery's trigger() method to manually raise a change event on the field after setting its val().
Also, note that $('#totalall').val(allA); needs to be $('#totalall').val(alltotal); instead.
$(document).ready(function() { // working
$('#maleA,#femaleA').change(function() {
maleA = $('#maleA').val();
femaleA = $('#femaleA').val();
allA = Number(maleA) + Number(femaleA);
$('#totalA').val(allA).trigger('change');
}),
$('#maleB,#femaleB').change(function() {
maleB = $('#maleB').val();
femaleB = $('#femaleB').val();
allB = Number(maleB) + Number(femaleB);
$('#totalB').val(allB).trigger('change');
}),
$('#maleA,#maleB').change(function() {
maleA = $('#maleA').val();
maleB = $('#maleB').val();
allmale = Number(maleA) + Number(maleB);
$('#maletotal').val(allmale).trigger('change');
}),
$('#femaleA,#femaleB').change(function() {
femaleA = $('#femaleA').val();
femaleB = $('#femaleB').val();
allfemale = Number(femaleA) + Number(femaleB);
$('#femaletotal').val(allfemale).trigger('change');
}),
//problem is here
$('#maletotal,#femaletotal').change(function() {
allmale = $('#maletotal').val(); //feed by javascript
allfemale = $('#femaletotal').val(); //feed by javascript
alltotal = Number(allmale) + Number(allfemale);
$('#totalall').val(alltotal);
})
})

However, you can improve the code quality and extensibility by using common classes on the elements to group them by behaviour. This makes the JS much more succinct and will work for an infinite number of 'Section' blocks. Try this:
jQuery($ => {
let $inputs = $('.input');
let $totalMale = $('#overall-male');
let $totalFemale = $('#overall-female');
let $totalOverall = $('#overall-total');
let updateRowTotal = $row => {
let maleCount = parseInt($row.find('.male').val(), 10) || 0;
let femaleCount = parseInt($row.find('.female').val(), 10) || 0;
$row.find('.total').val(maleCount + femaleCount);
}
let updateOverallTotal = () => {
let maleCount = 0;
$inputs.filter('.male').each((i, el) => maleCount += (parseInt(el.value, 10) || 0));
$totalMale.val(maleCount);
let femaleCount = 0;
$inputs.filter('.female').each((i, el) => femaleCount += (parseInt(el.value, 10) || 0));
$totalFemale.val(femaleCount);
$totalOverall.val(maleCount + femaleCount);
}
$inputs.on('input', e => {
updateRowTotal($(e.currentTarget).closest('.row'));
updateOverallTotal();
});
})
input {
width: 70px;
text-align-last: center;
}

The change event triggers only on user action. You can either use .trigger is mentioned in the above answer or invoke the final method as below,
$(document).ready(function()
{
$('#maleA,#femaleA').change(function()
{
maleA = $('#maleA').val();
femaleA = $('#femaleA').val();
allA = Number(maleA)+Number(femaleA);
$('#totalA').val(allA);
changeAllTotal();
}),
$('#maleB,#femaleB').change(function()
{
maleB = $('#maleB').val();
femaleB = $('#femaleB').val();
allB = Number(maleB)+Number(femaleB);
$('#totalB').val(allB);
changeAllTotal();
}),
$('#maleA,#maleB').change(function()
{
maleA = $('#maleA').val();
maleB = $('#maleB').val();
allmale = Number(maleA)+Number(maleB);
$('#maletotal').val(allmale);
changeAllTotal();
}),
$('#femaleA,#femaleB').change(function()
{
femaleA = $('#femaleA').val();
femaleB = $('#femaleB').val();
allfemale = Number(femaleA)+Number(femaleB);
$('#femaletotal').val(allfemale);
changeAllTotal();
})
function changeAllTotal()
{
allmale = $('#maletotal').val(); //feed by javascript
allfemale = $('#femaletotal').val(); //feed by javascript
alltotal = Number(allmale)+Number(allfemale);
$('#totalall').val(alltotal);
}
})

Admittedly, the following might appear rather condensed. But it shows that the code can be done in a much shorter way enabling it to deal with even wider tables (without the need for ids).
const Asum=DOMArr=>DOMArr.reduce((a,c)=>((a+=+c.value),a),0); // summation utility function
// find arrays of males, females and their summation fields:
const males=$(".male").get(),msum =males.pop(), females=$(".female").get(),fsum=females.pop();
// take care of all summation fields leading to grand total: gtot
let tots = $(".total").get(), gtot=tots.pop();
tots = tots.map(t=>([t,$(t).closest(".row").find("input:not([readonly])").get()]));
$(document).on("input","input",function(){
[[msum,males],[fsum,females],...tots,[gtot,[msum,fsum]]].forEach(([e,a])=>e.value=Asum(a))
})
input {
width: 40px;
text-align-last: center;
}

</div>
</div>
Regrettably, it does not work:
So I switched my idea. Why not use flex-grid row to hold 2 stacked div: abcs and 123s?
<div class="row justify-content-start">
<div>
<div>
<b>aaaaaaaaaaaaaaa</b>
</div>
<div>
<b>bbb</b>
</div>
</div>
<div>
<div>
111
</div>
<div>
222
</div>
</div>
</div>
Actually, it works.
What bothers me is that the implementation is kind of lengthy and jumbled. Is there a better way to achieve the goal?
Hope for your help. :-)

As commented, you need a table layout:
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/css/bootstrap.min.css" >
<div class="d-table">
<div class="d-table-row ">
<div class="cls d-table-cell">
<b>aaaaaaaaaaaaaaa</b>
</div>
<div class="cls d-table-cell">
111
</div>
</div>
<div class="d-table-row">
<div class="cl d-table-cells">
<b>bbb</b>
</div>
<div class="cls d-table-cell">
222
</div>
</div>
<div class="d-table-row">
<div class="cls d-table-cell">
<b>ccccc</b>
</div>
<div class="cls d-table-cell">
33333333333
</div>
</div>
<div class="d-table-row">
<div class="cls d-table-cell">
<b>dddddddddd</b>
</div>
<div class="cls d-table-cell">

HTML broken Format with hidden divs

I am trying to put a web form together for work that after a selection from a drop down is made the correct questions with be revealed up to be filled out. I have the form working, however, my formatting is all out of whack. What I would like to do is keep everything in a nice straight line when displaying the questions without any gaps with the hidden text
When you Run the program you can see a space between the drop down and the questions 49 and 50 (if it is possible I would want to eliminate that gap), I also tried to hide a whole div If you were to select "Red" it will then separate question into 3 parts.
I have tried to cut the code down as much as I could. Here is the Fiddle
<!-- Main Content Area -->
<div class="main">
<div class="row">
<form> <!-- Form tag is only used to allow the Clear button at the bottom to clear the data entry area. -->
<!-- Begin left side data entry -->

<div class="row">

});
If this is something that is impossible with the way I am trying to build this, I welcome any suggestions that I can research to get to my final product. Thank you in advance.

The JS code fails to execute (or do anything) when I click the submit button

I'm just learning Javascript, and this is my first attempt to make something for myself, so forgive me if the solution is very simple. I'm trying to automate score keeping for a card game. When I click the submit button, nothing happens.
<div class="container body-content">
<div class="row mt-4 justify-content-center">
<div class="col-auto">
<img class="img-fluid logo" alt="cards" src="img/cards.png">
</div>
<div class="col-4">
<h1>Shayne's Golf Tally</h1>
</div>
</div>
<div class="row justify-content-center text-center round">
<div class="col">
<h2 id="round">Round: 0</h2>
</div>
</div>
<div class="row justify-content-center text-center mt-3">
<div class="col-3">
<h3 class="names">Shayne</h3>
<h3 id="shayne">0</h3>
</div>
<div class="col-3">
<h3 class="names">Amber</h3>
<h3 id="amber">0</h3>
</div>
</div>
<div class="row justify-content-center">
<div class="col-3 centered input-spacing">
<input class="form-control input-form" id="inputShayne">
</div>
<div class="col-3 centered input-spacing">
<input class="form-control input-form" id="inputAmber">
</div>
</div>
<div class="row justify-content-center text-center mt-4">
<div class="col">
<button class="btn btn-primary" onclick="tallyScore()">Submit</button>
</div>
</div>
</div>

And the javascript:
var round = 0;
var scoreShayne = 0;
var scoreAmber = 0;
function tallyScore() {
round += 1;
document.getElementById(round).innerHTML = "Round: " + round;
scoreShayne += document.getElementById("inputShayne").value;
scoreAmber += document.getElementById("inputAmber").value;
document.getElementById(shayne).innerHTML = scoreShayne;
document.getElementById(amber).innerHTML = scoreAmber;
}

some recommandations in this code, just to see ;)
// global values
var round = 0
, scoreShayne = 0
, scoreAmber = 0
;
// use constants to prevent the JS interpreter from recalculating each call
const hmi_round = document.getElementById('round')
, hmi_shayne = document.getElementById('shayne')
, hmi_amber = document.getElementById('amber')
, hmi_inputShayne = document.getElementById('inputShayne')
, hmi_inputAmber = document.getElementById('inputAmber')
;
function tallyScore()
{
hmi_round.textContent = "Round: " + ++round; // ++round is a direct increment (different from round++ )
hmi_shayne.textContent = scoreShayne += hmi_inputShayne.valueAsNumber; // HTML5 as valueAsNumber
hmi_amber.textContent = scoreAmber += hmi_inputAmber.valueAsNumber; // instead of parseInt(hmi_inputAmber.value)
hmi_inputShayne.value = "0"; // reset values for the next round
hmi_inputAmber.value = "0";
}

func is not defined at HTMLButtonElement.onclick

I'm trying to create a simple webpage using Flask, I'm trying to capture the text written in a textfield in a javascript variable and then display it on console, when the user presses a button.
Here is the code
HTML
<script type="text/javascript" language="javascript" src="{{url_for('static',filename='js/main.js')}}"></script>
<div class="container">
<div class="row">
<div class="col-md-3"></div>
<div class="col-md-6">
<input type="text" id="txtWord" name="search" placeholder="Search..." >
</div>
<div class="col-md-3"></div>
</div>
<div class="row">
<div class="col-md-3"></div>
<div class="col-md-6">
<input type="text" name="search" placeholder="# Result..." id="inputNumResults">
</div>
<div class="col-md-3"></div>
</div>
<div class="row">
<div class="col-md-4"></div>
<div class="col-md-4 text-center">
<br>
<button class="btn btn-success" type="button" id="buttonSearch" onclick="getText()">Search for words</button>
</div>
<div class="col-md-4"></div>
</div>
Javascript
function getText() {
var txt = document.getElementById('txtWord').innerHTML;
console.log(txt);
}

Here is working solution
<div class="row">
<div class="col-md-3"></div>
<div class="col-md-6">
<input type="text" id="txtWord" name="search" placeholder="Search..." >
</div>
<div class="col-md-3"></div>
</div>
<div class="row">
<div class="col-md-3"></div>
<div class="col-md-6">
<input type="text" name="search" placeholder="# Result..." id="inputNumResults">
</div>
<div class="col-md-3"></div>
</div>
<div class="row">
<div class="col-md-4"></div>
<div class="col-md-4 text-center">
<br>
<button class="btn btn-success" type="button" id="buttonSearch" onclick="gt()">Search for words</button>
</div>
<div class="col-md-4"></div>
</div>
<script>
function gt() {
var txt = document.getElementById("txtWord").value;
alert(txt);
}
</script>

I believe in Your case the problem is about order of loading this js file.
Always check what console displays, when I used "On load" load type it clearly returned an error that the function is not defined

You should simply clear your browser's cache. A full browser's cache can cause such a problem.

(function () {
function getText() {
var txt = document.getElementById('txtWord').value;
console.log(txt);
}
document.getElementById('buttonSearch').addEventListener('click', getText, true);
})();
<div class="container">
<div class="row">
<div class="col-md-3"></div>
<div class="col-md-6">
<input type="text" id="txtWord" name="search" placeholder="Search..." >
</div>
<div class="col-md-3"></div>
</div>
<div class="row">
<div class="col-md-3"></div>
<div class="col-md-6">
<input type="text" name="search" placeholder="# Result..." id="inputNumResults">
</div>
<div class="col-md-3"></div>
</div>
<div class="row">
<div class="col-md-4"></div>
<div class="col-md-4 text-center">
<button class="btn btn-success" type="button" id="buttonSearch">Search for words</button>
</div>
<div class="col-md-4"></div>
</div>
</div>

I was having the same problem using jQuery until I figure out that I declared the function inside the $(document).ready() method :
$(document).ready(function () {
function name(){} // not working
}
