clicking seekbar restarts video instead of seeking

$('.video-player').each(function(_, videoPlayer) {
let eleVideoObj = $(videoPlayer).find("video");
let eleVideoSeekbar = $(videoPlayer).find(".video-seekbar");
let eleVideoProgress = $(eleVideoSeekbar).find(".progress");
let totalDurationInSeconds = 0;
let currentTimeInSeconds = 0;
let currentDuration = null;
let totalDuration = null;
$(eleVideoSeekbar).on('click', e => {
let tempSeekPosition =
e.pageX - videoPlayer.offsetLeft - eleVideoSeekbar['0'].offsetLeft;
let tempSeekValue = tempSeekPosition / eleVideoSeekbar['0'].clientWidth;
eleVideoObj['0'].currentTime = tempSeekValue * totalDurationInSeconds;
});
}
Ive been trying to look and see why it's restarting the video but i can't and haven't yet
I need to know why is causing this to happen because as you may have guessed it's going on my website
thanks in advance!

Ok i figured it out after messing with it and trying to figure it out
i removed the the videoPlayer instance now it goes
e.pageX - eleVideoSeekbar['0'].offsetLeft;
instead of
e.pageX - videoPlayer.offsetLeft - eleVideoSeekbar['0'].offsetLeft;
$('.video-player').each(function(_, videoPlayer) {
let eleVideoObj = $(videoPlayer).find("video");
let eleVideoSeekbar = $(videoPlayer).find(".video-seekbar");
let eleVideoProgress = $(eleVideoSeekbar).find(".progress");
let totalDurationInSeconds = 0;
let currentTimeInSeconds = 0;
let currentDuration = null;
let totalDuration = null;
$(eleVideoSeekbar).on('click', e => {
let tempSeekPosition =
e.pageX - eleVideoSeekbar['0'].offsetLeft;
let tempSeekValue = tempSeekPosition / eleVideoSeekbar['0'].clientWidth;
eleVideoObj['0'].currentTime = tempSeekValue * totalDurationInSeconds;
});```

Access parent object property of image element

I have a list of cats. Each cat object has a property cat.clicks that record the number of times the cat image has been clicked. The cat image's onclick calls the method cat.clickCat.
But of course 'this' in the clickCat method refers to the image element and not the cat object which contains the property 'clicks'.
How do I display and update the number of clicks on the image?
function Cat(src, name) {
this.src = src;
this.name = name;
this.clicks = 0; //property recording no. of clicks
}
Cat.prototype.createCatItem = function() {
let catDisplay = document.createElement("div");
catDisplay.id = "catDisplay"
let catName = document.createElement("h2");
let catImg = document.createElement("img");
let catCounter = document.createElement("div");
catCounter.id = "clicker";
catName.innerHTML = this.name;
catImg.src = this.src;
catImg.onclick = this.clickCat; //call the clickCat method
catDisplay.appendChild(catName);
catDisplay.appendChild(catImg);
catDisplay.appendChild(catCounter);
return catDisplay;
}
Cat.prototype.clickCat = function() {
this.clicks += 1; //how to access the object property clicks from this method?
let clickerDiv = document.getElementById("clicker")
clickerDiv.innerHTML = ''
clickerDiv.innerHTML = 'clicks = ' + this.clicks;
}
function App() {
this.cats = [];
}
App.prototype.add = function(cat) {
this.cats.push(cat)
}
App.prototype.listCats = function() {
let container = document.getElementById("container");
let ul = document.createElement("ul");
for (let i=0; i<this.cats.length; i++){
let li = document.createElement("li");
li.innerHTML = this.cats[i].name;
li.onclick = this.displayCat;
ul.appendChild(li);
}
container.appendChild(ul);
}
App.prototype.displayCat = function() {
let container = document.getElementById("container");
let catDisplay = document.getElementById("catDisplay")
let cats = app.cats;
let chosenCat = cats.filter(cat => cat.name === this.innerHTML);
let chosenCatItem = chosenCat[0].createCatItem();
container.removeChild(catDisplay);
container.appendChild(chosenCatItem);
console.log(chosenCat);
}
App.prototype.showFirstCat = function() {
let container = document.getElementById("container");
let catDisplay = document.getElementById("catDisplay")
let firstCat = app.cats[0].createCatItem();
container.appendChild(firstCat);
}
let app = new App;
let tea = new Cat("http://placehold.it/350x150", "tea");
let snowball = new Cat("http://placehold.it/350x200", "snowball");
let triksy = new Cat("http://placehold.it/350x300", "triksy");
let vera = new Cat("http://placehold.it/350x350", "vera");
let jon = new Cat("http://placehold.it/350x400", "jon");
app.add(tea)
app.add(snowball)
app.add(triksy)
app.add(vera)
app.add(jon)
app.listCats();
app.showFirstCat();
<div id="container">
<h1>My Cat Clicker</h1>
</div>

First of all .. beware of using this ... this always refer the object currently responsible to execute the scripts in browser ... so in your case the image is responsible for executing the click event and it has no property called clicks .. and that's why clicks is NaN
A good practice is preserve this into a variable to avoid the system replacement when executing (that=this)
Cat.prototype.createCatItem = function() {
let that=this; //preserving this value
let catDisplay = document.createElement("div");
catDisplay.id = "catDisplay"
let catName = document.createElement("h2");
let catImg = document.createElement("img");
let catCounter = document.createElement("div");
catCounter.id = "clicker";
catName.innerHTML = this.name;
catImg.src = this.src;
catImg.onclick = function() {
//alert(this);
that.clicks += 1; //how to access the object property clicks from this method?
let clickerDiv = document.getElementById("clicker")
clickerDiv.innerHTML = ''
clickerDiv.innerHTML = 'clicks = ' + that.clicks;
}
catDisplay.appendChild(catName);
catDisplay.appendChild(catImg);
catDisplay.appendChild(catCounter);
return catDisplay;
}
//Cat.prototype.clickCat = function() {
// this.clicks += 1; //how to access the object property clicks from this method?
// let clickerDiv = document.getElementById("clicker")
// clickerDiv.innerHTML = ''
// clickerDiv.innerHTML = 'clicks = ' + this.clicks;
//}

Reset values Issue

Building a dice game and you get 3 rolls. Once you finish your turn i'm trying to have a "reset" button that will reset the values back to the original spot so the "next person" can play. The values reset as I expected but when I "roll" none of the functions are taking place and i'm pretty new in js so i'm not sure what the problem is.
var playerScore = document.getElementById('firstPlayerScore');
var rollButton = document.getElementById('roll_button');

Here is a link to the live game since it's the only way I can describe the problem since I don't know what's not working. If you roll the dice a couple times the dice will get a blue border and be "saved" according to the rules. Now after you hit th restart button that doesn't happen anymore.
Thanks for the help in advance guys

Just add this to your restart()
function restart(){
...
shipExist = false;
capExist = false;
crewExist = false;
...
}

It's hard to replicate without a fiddle, but it seems that you are adding and removing the 'glowing' class using separate processes. Have you tried adding the glowing class the same way you are removing it?
element.classList.add("glowing")
See an example within a fiddle: https://jsfiddle.net/5tstf2f8/

Link rotating images in existing javascript

its been a while since I've dug my heals into JS and could use some help. Looking to modify this existing script to include a link for each rotating image... want to link the object called "text" to the same URL for each image. any ideas?
//cur_index = 1;
cur_index = Math.floor(Math.random()*6);
//var randomnumber=Math.floor(Math.random()*11)
num_image = 5;
//alert(cur_index);
interval = 300000; // 5min between rotations
function rotate(){
// if(cur_index > num_image)
// cur_index = 1;
if(cur_index == 0)
cur_index = 1;
var imag,text;
if(document.getElementById){
imag = document.getElementById("faceImage");
text = document.getElementById("faceText");
}else if(document.all) {
imag = document.all["faceImage"];
text = document.all["faceText"];
}else if(document.layers){
imag = document.layers["faceImage"];
text = document.layers["faceText"];
}
var imageUrl = "/path/face" + cur_index + ".jpg";
var textUrl = "/path/face" + cur_index + "_text.gif";
imag.src = imageUrl;
text.src = textUrl;
//cur_index++;
cur_index = Math.floor(Math.random()*6);
setTimeout('rotate()',interval);
}

(Javascript) SlideShow Not Working

Hello fellow stackoverflow members,
I've been trying to make a Slideshow. I've referenced from many other sites including this one but the pictures aren't showing up in the container element nor are the "prev" and "next" buttons functioning properly. I'd appreciate it if I got help! :)
my code:
var photos = newArray ();
photos[0] = "img/image(2).jpg";
photos[1] = "img/image(4).jpg";
photos[2] = "img/image(6).jpg";
photos[3] = "img/image(8).jpg";
photos[4] = "img/image(10).jpg";
photos[5] = "img/image(12).jpg";
photos[6] = "img/image(14).jpg";
photos[7] = "img/image(16).jpg";
photos[8] = "img/image(18).jpg";
photos[9] = "img/image(20).jpg";
photos[10] = "img/image(22).jpg";
photos[11] = "img/image(24).jpg"
//END OF PHOTOS ARRAY//
var i = 0;
var k = photos.length-1;
function next.onclick() {
var img= document.getElementById("image-container");
img.src = photos[i];
if (i < k ) {
i++;
}else {
i = 0; }
}
function prev.onclick() {
var img= document.getElementById("image-container");
img.src=photos[i];
if)i > 0) {i--;}
else {i = k; }
}
getImageArray = function(containerId) {
var containerElement = document.getElementById(container);
if (containerElement) {
var imageArray = containerElement.getElementById("container");
return photos[i];
} else {
return null;
}
}
this is what my slideshow looks like (it's broken)
http://prntscr.com/5dcfzq
The share button isn't important, I can make that work at least.
The main problem is that the pictures aren't showing and the back and foward buttons are messed up :'(
p.s ( I'm not sure if part of the reason is how I'm linking to the "next" or "back" functions with the div tag, because i'm this is how i'm doing it :
<div id = "back" onclick = "prev()"></div>

OK ... to summarize ...
1. var photos = newArray ();
There needs to be a space between new and Array, so ...
var photos = new Array();
2. function prev.onclick() { needs to be just function prev() {
3. Same with next.onclick() based on usage in HTML.
4. In prev() ... if)i > 0) {i--;} should be ...
if (i > 0) { i--; }
5. WRONG: Also in prev()' ... else should bei = k-1;`
6. DO NOT NEED Not sure why you have the getImageArray function at all.
7. This assumes there is an '' tag in the HTML.
UPDATE:
Here's the code that works ... this all goes in the body:
These are my assumptions in the body ...
<img id="image-container" />
<div id="back" onclick="prev()">Previous</div>
<div id="next" onclick="mext()">Next</div>
The script code MUST be at the end of the body ...
<script>
var photos = new Array ();
photos[0] = "img/image(2).jpg";
photos[1] = "img/image(4).jpg";
photos[2] = "img/image(6).jpg";
photos[3] = "img/image(8).jpg";
photos[4] = "img/image(10).jpg";
photos[5] = "img/image(12).jpg";
photos[6] = "img/image(14).jpg";
photos[7] = "img/image(16).jpg";
photos[8] = "img/image(18).jpg";
photos[9] = "img/image(20).jpg";
photos[10] = "img/image(22).jpg";
photos[11] = "img/image(24).jpg"
//END OF PHOTOS ARRAY//
// Here, I set the img variable so that it can be re-used.
// I also loaded the first image ...
var i = 0;
var k = photos.length-1;
var img = document.getElementById("image-container");
img.src = photos[i];
function next() {
img.src = photos[i];
if (i<k) {
i++;
} else {
i = 0;
}
}
function prev() {
img.src=photos[i];
if (i>0) {
i--;
} else {
i = k;
}
}
</script>
