I am getting a file not found undefined Error in Jquery - javascript

Hello I am creating a game similar to Simon. Where a user has to memorize a random color generated by the random color generator. When a button is clicked it is supposed to play a sound. I am able to play all the sounds when I click the buttons. I created a function that recognizes when the enter key is pressed to start the game. The game generates a random color with a corresponding sound and the user is supposed to click the same color. I am getting a ERROR NOT FOUND sounds/undefined.mp3 and also a DOM Exception: no supported source was found. It seems not to be able to find the right file.
function nextSequence() {
level = level + 1;
randomNumber = Math.floor(Math.random * 4);
randomChosenColor = buttonColors[randomNumber];
gamePattern.push(randomChosenColor);
console.log(gamePattern);
//$("#" + randomChosenColor).fadeOut(100).fadeIn(100).fadeOut(100).fadeIn(100);
animatePress(randomChosenColor);
playSound(randomChosenColor);
// animatePress(randomChosenColor);
}
$(".btn").click(function() {
var userChosenColor = $(this).attr("id");
userClickedPattern.push(userChosenColor);
console.log(userClickedPattern);
playSound(userChosenColor);
animatePress(userChosenColor);
});
function playSound(variable) {
$("#" + variable).ready(function() {
var audio = new Audio("sounds/" + variable + ".mp3");
audio.play();
});
}
$(document).on('keypress', function(e) {
if(e.which == 13) {
var h1header = document.getElementById("level-started").innerHTML = "Level " + level;
nextSequence();
started = true;
}
});

How to prevent content(Tasks) to disappear after REFRESHING

I am trying to make a simple To-Do like application. I want the "Tasks" which I add to remain even after closing the window or at least after refreshing. I tried to achieve that using MongoDB but I couldn't.
I think a simpler way to achieve this is by using arrays but I am not able to understand how to do that.
Please suggest me some way to achieve the above results....
let div = document.getElementById('tasks');
let add = document.getElementById('add');
let newTask = document.getElementById('newTask');
let c = 0;
add.addEventListener("click", function () {
let cbox = document.createElement("input");
let d = document.createElement("div");
let newt = newTask.value;
newTask.value = null;
cbox.type = "checkbox";
cbox.id = "check";
div.append(d);
d.id = "nd";
d.append(cbox);
d.append(newt);
c += 1;
if (c === 12) {
add.disabled = true;
newTask.value = "Stack Overflow";
}
});

You can use localStorage to save data in browser storage.
here's link to documentation for localStorage .
//to set data in local storage
localStorage.setItem('myCat', 'Tom')
//to get data from localStorage
const cat = localStorage.getItem('myCat');
//to remove data from localStorage
localStorage.removeItem('myCat');
//for object you can stringify them
var myObj = [{name:"test", time:"Date 2017-02-03T08:38:04.449Z"}];
localStorage.setItem('item', JSON.stringify(myObj));
//Then when you want to retrieve data, you need to parse the string to object again.
var getObj = JSON.parse(localStorage.getItem('item'));

queryselector can not find id

I am trying to query a cloned element in my dom and queryselector can not find it. Specifically #reply_form brings up nothing despite the id being used in the template. I've also tried ("#reply_form"+post_id) since I re id it at the bottom before pushing it to the dom and nothing. I'm all out of ideas.
Here is the code:
<template id="reply_template">
<div class="lk">
<img class="profile_image" />
<div>
<div class="user">
<div class="reply_author"></div>
<div class="reply-body"></div>

When using getElementById you don't need to pass # in the string. check following snippet.
function open_form(post_id) {
console.log("reply" + post_id)
document.getElementById("reply" + post_id).classList.toggle("blue");
document.getElementById("reply_form" + post_id).classList.toggle("open");
document.getElementById("vl" + post_id).classList.toggle("open");
}
.like-comment,
.reply_comment {
cursor: pointer;
}
.vl {

Javascript for hiding the image and changing the text is not working

This is my code here:
I want to hide the image when the mouse rolls over and only display text.Then again, when the mouse moves away, the image should be visible.
The text property is working just fine but image is having issues.
It completely disappears after clicking.
function updated1(element){
document.getElementById("d1").innerHTML = "web deveopment and designing, html css js and bootstrap";
document.getElementById("d1").style.borderRadius = "4.5%";
document.getElementById("imgd1").style.visibility = 'hidden';
}
function undod1(){
document.getElementById("d1").innerHTML = "WEB DEVELOPMENT";
document.getElementById("d1").style.borderRadius = "0%";
document.getElementById("imgd1").style.visibility = 'visible';
}

when you set innerHTML you are wiping out your image
function updated1(element){
document.getElementById("d1").innerHTML = "web deveopment and designing, html css js and bootstrap";

document.getElementById("imgd1").style.visibility = 'hidden';

Your problem is this part
document.getElementById("d1").innerHTML = "...";
Because this code removes all the children from the parent and inserts the text. So basically, when your mouse leaves, there is no image there to make it visible. You don't need that much Javasctipt to create the effect you desire. Better HML, more CSS and less JS:
<section
id="d1"
class="col-md-4 col-md-push-4 col-xs-12"
onmouseover="updated1(this)"
onmouseleave="undod1()"
>
<p class="message">WEB DEVELOPMENT<p>
<img id="imgd1" src="https://miro.medium.com/max/1200/1*pE2fOVDikEUwiQJlh4ggzg.jpeg" height="90%" width="90%">
</section>
#d1:hover {
border-radius: 4.5%;
}
img {
opacity: 1
}
#d1:hover img {
opacity: 0
}
let message = "WEB DEVELOPMENT";
let parent = document.querySelector("#d1");
let item = document.querySelector(".message");
function updated1(element){
item.innerText = "web deveopment and designing, html css js and bootstrap";
}
function undod1(){
item.innerText = message;
}
If you try doing something more complex than you asked, try to add/remove classes to change style instead of adding styles in Javascript. This is an easier and cleaner way to change styles.

Password Generator does not work until I move slider

Problem: My password generator will not work until I move my slider. However, I would like the value to default to 8. So if someone loads page, and clicks generate PW, a random pw of 8 would populate.
//generate a password function
function passwordGenerator () {
// Length of the password?
var passwordLength = document.getElementById('num').value;
// characters options for PW

I have played with HTML and JS. I have tried to create a var num = 8;
no luck.
Does anyone have any ideas on how I can do this?
At the start of your passwordGenerator function:
var passwordLength = document.getElementById('num').value;
This element (<span id="num">8</span>) doesn't have a value attribute, so your function will try to generate a password with a length equal to undefined.
You should get the value from your slider instead:
var passwordLength = document.getElementById('slider1').value;
You can also simplify your function sliderMove function:
function sliderMove() {
document.getElementById('num').textContent = document.getElementById('slider1').value;
}

Highlight comment and remove class when delete button is clicked

I am new to web development and currently learning jQuery from codecademy.

I have created a fiddle to provide something close to the desired functionality. I'm not sure what you mean by "highlight" the comment, but what you are looking for is event delegation. Using jQuery's .on() function, you can listen for events on dynamically created elements:
$('body').on('click', '.btnDelete', function(){
$(this).closest('li').remove();
});
See this jsFiddle: http://jsfiddle.net/voveson/5gL44z6m/2/
And for more info on how the .on() function works, see here.
