Why my functionality doesn't work after conditionally innerHTML? - javascript

I have a few checkboxes which represent subjects. And I have two custom(radio) select. I want to change innerHTML of my first select due to checkbox:checked length. If selected chekboxes length less than 3 I want to render different select options else another select options. When page load it works fine but after recheck my checkboxes I can not select any option from my first chekbox. Can someone please look at and help me

In your javascript you have added eventListeners to all the select options when your page is loaded at first. But when you call the 'subjectChange' function, the innerHTMl is changed and new elements are added to your page but these new elements do not have eventListeners attached to them. You need to attach eventListeners to these elements as well. Like this :
function subjectChange (){
var subjectName = document.getElementsByName('subject-name');
var questionSel = document.getElementsByClassName('options-container')[0];
var checkBoxlength = 0;
for(var i = 0; i < subjectName.length; i++) {
if(subjectName[i].checked){
checkBoxlength++
}
}
if(checkBoxlength <= 3) {
questionSel.innerHTML = `
<label class="option">
<input type="radio" class="radio first" value="5" name="question" checked>
<span>5</span>
< /label>
<label class="option">
<input type="radio" class="radio first" value="10" name="question" checked>
<span>10</span>
</label>
`;
} else if(checkBoxlength >= 4) {
questionSel.innerHTML = `
<label class="option">
<input type="radio" class="radio first" value="5" name="question" checked>
<span>5</span>
</label>
<label class="option">
<input type="radio" class="radio first" value="10" name="question" checked>
<span>10</span>
</label>
<label class="option">
<input type="radio" class="radio first" value="15" name="question" checked>
<span>15</span>
</label>
`;
}
start(); //this will add eventListeners to all the elements again
}
function start(){
const selectBox = document.querySelectorAll('.select-box')
for(var i = 0; i < selectBox.length; i++) {
const selected = selectBox[i].querySelector('.selected');
const optionsContainer = selectBox[i].querySelector('.options-container');
const optionList = selectBox[i].querySelectorAll('.option');
selected.addEventListener('click', function(){
optionsContainer.classList.toggle("active");
})
optionList.forEach( o => {
var optionListItem= o.querySelectorAll('input[type="radio"]:checked + span');
optionListItem.forEach(e => selected.innerHTML = e.innerHTML)
o.addEventListener('click', function(){
var optionListItem= o.querySelectorAll('input[type="radio"]:checked + span');
optionListItem.forEach(e => selected.innerHTML = e.innerHTML)
optionsContainer.classList.remove('active')
var firstOptionList = document.querySelector('input[type="radio"]:checked');
var secondOptionList = document.querySelectorAll('.radio.second');
secondOptionList.forEach(e => {
e.removeAttribute('checked')
if(e.value == (firstOptionList.value * 2)){
//e.checked = true;
e.setAttribute('checked','');
var optionListItem2= document.querySelectorAll('input[type="radio"]:checked + span');
const selectedTwo = document.getElementsByClassName('selected');
optionListItem2.forEach(e => selectedTwo[1].innerHTML = e.innerHTML);
console.log(e)
}
})
})
})

Its Very simple,
Just Create And Put All Items into div#body
And You Have to use the event window.onclick
Then create if statement and check event.target.id == "body" ( To Check The Clicked Element is the div#body ( Not Its Children ) )
if (event.target.id == "body"){ /* Hiding Code */ }
Example
var w = window;
var a = document.getElementById("example");
var c = document.getElementById("okay");
var e = document.getElementById("yes-items");
a.addEventListener("click", check);
w.addEventListener("click", clickedBody);
function clickedBody(event){
if(event.target.id == "body"){
hideExplainIfOpened();
}
}
function check(){
if(c.checked){ showExplain();}
else{ hideExplain(); }
}
function hideExplainIfOpened(){
if(!e.classList.contains("d-none")){
hideExplain();
}
}
function showExplain(){ e.classList.remove("d-none"); }
function hideExplain(){ e.classList.add("d-none"); }

Showing a Result Table based on an array of Radio Buttons selected

I am new to coding. I'm trying to build an online form where there are a few questions that user will need to answer and questions are done in radio button options. Based on the array of radio buttons selected, I will then need to show the results on the same page. I'm thinking of using if..else statement but it doesn't seem to be working.
Here is my code:
<script>
function ShowHideDiv() {
if (document.getElementById("chkCitizen").checked ? && document.getElementById("chkMale").checked ?
&& document.getElementById("chkSingle").checked ? && document.getElementById("chkEmployed").checked ?
&& document.getElementById("chkNo").checked ? )
{
btn1.style.visibility = "visible";
var dvtext = document.getElementById("dvtext");
dvtext.style.display = "block" : "none";
}
else if (document.getElementById("chkCitizen") && document.getElementById("chkFemale")
&& document.getElementById("chkSingle") && document.getElementById("chkEmployed")
&& document.getElementById("chkNo")
{
btn1.style.visibility = "visible";
var dvtext = document.getElementById("dvtext");
dvtext.style.display = "block" : "none";
}
}
function resetFunction(){
document.getElementById("reliefChecker").reset();
}
</script>
Here's the full code with html and css:
<script>
function ShowHideDiv() {
if (document.getElementById("chkCitizen").checked && document.getElementById("chkMale").checked
&& document.getElementById("chkSingle").checked && document.getElementById("chkEmployed").checked

{
btn1.style.visibility = "visible";
var btn1 = document.getElementById("btn1");
var dvtext = document.getElementById("dvtext");
dvtext.style.display = "block" : "none";
}
else if (document.getElementById("chkCitizen").checked && document.getElementById("chkFemale").checked
&& document.getElementById("chkSingle").checked && document.getElementById("chkEmployed").checked
&& document.getElementById("chkNo").checked)
{
btn1.style.visibility = "visible";
var btn1 = document.getElementById("btn1");

You can try this one (as I understood, it works fine (if you have more questions, it can be done with loops) ).
HTML code is:

Add class to DIV element when quiz answer is correct or incorrect

I am trying to add a CSS class to a JavaScript created element, but am experiencing a reference error for the trackerMarker element. The tracker-marker DIVs are displaying on load, but are undefined when used in conjunction with the event listener.
I have tried using the createElement function inside and outside of the for loop.
I am not sure where the issue is. I am learning JS as I go, so any tips or suggestions are greatly appreciated.
function answerTracker() {
const answerTracker = document.querySelector(".tracker");
let questions = document.querySelectorAll(".container");
for (let i = 0; i < questions.length; i++) {
let trackerMarker = document.createElement("div");
trackerMarker.className = "tracker-marker";
answerTracker.appendChild(trackerMarker);
}
}
const runQuiz = (() => {
// Generate tracker
answerTracker();
let answers = document.querySelectorAll(".radio");
answers.forEach(function(answer) {
answer.addEventListener("click", (e) => {
let target = e.target;
let container = target.closest(".container");
let question = container.querySelector(".question");
let next = container.querySelector("button");
if (e.target.value == "t") {
trackerMarker.classList.add("correct");
} else {
trackerMarker.classList.add("incorrect");
}
if (next !== null && next !== "") {
next.style.display = "block";
}
question.style.display = "none";
});
});
})();

You never set trackerMarker inside runQuiz.
I used getElementsByClassName (because how you wrote your code) which will return an array of items which is not ideal. You should add an ID to your trackerMarker div and then use getElementById.
function answerTracker() {
const answerTracker = document.querySelector(".tracker");
let questions = document.querySelectorAll(".container");
for (let i = 0; i < questions.length; i++) {
let trackerMarker = document.createElement("div");
trackerMarker.className = "tracker-marker";
answerTracker.appendChild(trackerMarker);
}
}
const runQuiz = (() => {
// Generate tracker
answerTracker();
let answers = document.querySelectorAll(".radio");
answers.forEach(function(answer) {
answer.addEventListener("click", (e) => {
let target = e.target;
let container = target.closest(".container");
let question = container.querySelector(".question");
let next = container.querySelector("button");
let trackerMarker = document.getElementsByClassName('tracker-marker')[0];
// ^-- I added this line only
if (e.target.value == "t") {
trackerMarker.classList.add("correct");
} else {
trackerMarker.classList.add("incorrect");
}
if (next !== null && next !== "") {
next.style.display = "block";
}
question.style.display = "none";
});
});
})();

How to select all checkbox when i checked all check boxes

I want to select all checkbox checked when i select all checkboxes in my dropdown menu. I am a beginner js developer need help. This is my js code
var expanded = false;
function showCheckboxes() {
var checkboxes = document.getElementById("checkboxes");
if (!expanded) {
checkboxes.style.display = "block";
expanded = true;
} else {
checkboxes.style.display = "none";
expanded = false;
}
}
var selectallBox = document.getElementById('selectall');
var checkBoxes = document.querySelectorAll('.select-me');
selectallBox.addEventListener('click', function() {
for (var i = 0; i < checkBoxes.length; i++) {
if (checkBoxes[i] != selectallBox)
checkBoxes[i].checked = selectallBox.checked;
}
})
for (var i = 0; i < checkBoxes.length; i++) {
checkBoxes[i].addEventListener('click', function() {
selectallBox.checked = false;
})
}
document.querySelector('.close-check-box').addEventListener('click' , function(){
checkboxes.style.display = 'none'
})
This is my js fiddle:
https://jsfiddle.net/b9ueL3fw/

You can compare the total check box with the checked check box count, if both length are same then set check box checked property to true, otherwise set to false:
var selectedCount = document.querySelectorAll('.select-me:checked').length;
if(checkBoxes.length == selectedCount){
selectallBox.checked = true;
}
else{
selectallBox.checked = false;
}
var expanded = false;
var selectBox = document.querySelector('.selectBox')
selectBox.addEventListener('click', function(){
var checkboxes = document.getElementById("checkboxes");
if (!expanded) {
checkboxes.style.display = "block";
expanded = true;
} else {
checkboxes.style.display = "none";
expanded = false;
}
});
var selectallBox = document.getElementById('selectall');
var checkBoxes = document.querySelectorAll('.select-me');
selectallBox.addEventListener('click', function() {
for (let i = 0; i < checkBoxes.length; i++) {
if (checkBoxes[i] != selectallBox)
checkBoxes[i].checked = selectallBox.checked;
}
})
for (var i = 0; i < checkBoxes.length; i++) {
checkBoxes[i].addEventListener('click', function() {
var selectedCount = document.querySelectorAll('.select-me:checked').length;
if(checkBoxes.length == selectedCount){
selectallBox.checked = true;
}
else{
selectallBox.checked = false;
}
});
}
document.querySelector('.close-check-box').addEventListener('click' , function(){
checkboxes.style.display = 'none'
})

jQuery not reacting to number input

I have this code, where if I fill in specific input fields then it will 'enable' or in this case remove a class but when it comes to filling in an input field of a number it won't react to the input value of the number what is filled. I want it to when something is filled in then enable the button.
I'm setting up a validation that when not all the fields are filled in, you can't go to the next page but before that you need to fill in all the fields.

I want the result to be when I filled in everything and I filled something in the number input(example: '1') that it reacts to it immediately and enables the button or in this case adds a class.

Here's the code similar for your application.
It interacts with both "radio buttons" as well as "input box" & accordingly triggers the "Submit button".
function checkout() {
alert("It worked");
}
$(document).ready(function() {
//console.log("Document loaded !");
$("input").change(function() {
var snacksValue = $('input[name="snacks"]:checked').val();
var extrasValue = $('input[name="extras"]:checked').val();
var quantity = $('#input1').val();
if (snacksValue != undefined && extrasValue != undefined && quantity != '') {
//console.log("go");
$('#checkout').removeClass("disabled");
$('#checkout').addClass("enabled");
} else {
//console.log("error");
$('#checkout').removeClass("enabled");
$('#checkout').addClass("disabled");
}
});
});
