I need to make a high-score list for this Javascript game

I hope you can give me a hand with this. My idea is to show a list of high-scores after the game is finished for a Doodle Jump project (javascript). The high-scores are presented successfully as you will see in my code, but the presentation is poor. Hence, I want to show them in a blank page, if possible using the same html. I will leave my code for you to reproduce the issue and help me. I thought about some document command, but you tell me.
Thanks in advance.

}
<ol id="highScores"></ol>
<div class="grid">
<div class="volumeIcon"></div>
</div>
I included what I think will reproduce the situation. Hope this helps you help me.

Why not just put:
<ol id = "highScores"></ol>
within a <div> and give that a class that has display: none initally? Like this:
<div class="high-scores-container">
<ol id = "highScores"></ol>
</div>
.high-scores-container {
display: none;
height: 100%;
}
Then when you run your showHighScores() function, grab the high-scores-container div and change the display to block and then at the same time, grab the grid div and set that to display: none. That will give you the effect of displaying your high scores on a separate page but you're just doing so with JS/CSS.

Ticker-style getting cut in Mobile View

The requirement is to sow the information continuously hence opted for a ticker style.
Now I am using an [ticker-style.css] along with [jquery.ticker.js]
It works fine in a Full Screen however while browsing in a Mobile/Tabler - the text is getting cut (see below screenshot) - I tried to play around the width however the rendering was not as expected.
Can you help here.
Thanks in advance.

The problem is that you are setting fixed widths for ticker elements.The ticker container has a width of 720px no matter what size the screen, and on screens < 767px the container for the scrolling text is just 230px.
Either change the CSS if it is your own, or if not you can add these rules after the Ticker CSS in included:
#media (max-width: 767px){
.ticker-wrapper.has-js,
.ticker,
.trending-tittle .ticker {
width: 100%!important;
}
}
This sets them to use the full width of the screen.

Jump to end of progress bar when complete

I have working but ugly solution.
Idea is:
Run progress bar before ajax call
Jump to end of progress bar when complete (or fail)
Wait at 90% if ajax call is not finished yet (when finish than jump to end)
There are at least three problems in my solution:
I have to reset progress bar 'width' in 3 places.
I must have public variable (widthProgressBar)
I cannot reuse function 'startProgress' in case I want to have two progress bars at same page.
This is my solution: http://jsfiddle.net/WQXXT/5403/
var widthProgressBarPing = 0;
// handles the click event, sends the query
function getSuccessOutput() {
widthProgressBar = 0;
startProgress("pingTestBar");
$.ajax({
url: '/echo/js/?js=hello%20world!',
complete: function(response) {
widthProgressBar = 99;
},
error: function() {
widthProgressBar = 99;
},
});
return false;
}
function startProgress(barId) {
var elem = document.getElementById(barId);
var id = setInterval(frame, 15);
function frame() {
if (widthProgressBar >= 90 && widthProgressBar < 99) {}
if (widthProgressBar >= 100) {
clearInterval(id);
} else {
widthProgressBar++;
elem.style.width = widthProgressBar + '%';
elem.innerHTML = widthProgressBar * 1 + '%';
}
}
}
.testProgress {
width: 100%;
background-color: #ddd;
}
.testProgressBar {
width: 0%;
height: 30px;
background-color: #4CAF50;
text-align: center;
line-height: 30px;
color: white;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
test success |
<div class="testProgress">
<div id="pingTestBar" class="testProgressBar"></div>
</div>

I believe this is the right approach, without changing unnecessary variables outside usage scope.
// handles the click event, sends the query
function getSuccessOutput() {
var bar = new Bar("pingTestBar");
$.ajax({
url: '/echo/js/?js=hello%20world!',
complete: function(response) {
bar.finish()
},
error: function() {
bar.finish()
},
});
return false;
}
function Bar(barId) {
var self = this;
self.w = 0;
var elem = document.getElementById(barId);
var id = setInterval(frame, 15);
this.finish = function(){
clearInterval(id);
self.w = 100;
changeElem()
}
function changeElem(){
elem.style.width = self.w + '%';
elem.innerHTML = self.w * 1 + '%';
}
function frame() {
if (self.w >= 90 && self.w < 99) {}
if (self.w >= 100) {
} else {
self.w++;
changeElem()
}
}
}
.testProgress {
width: 100%;
background-color: #ddd;
}
.testProgressBar {
width: 0%;
height: 30px;
background-color: #4CAF50;
text-align: center;
line-height: 30px;
color: white;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
test success |
<div class="testProgress">
<div id="pingTestBar" class="testProgressBar"></div>
</div>

Here's your code modified.
I eliminated the global var widthProgressBarPing by using the width of the barId element that's always there (var widthProgressBar = elem.style.width.slice(0, -4);).
// handles the click event, sends the query
function getSuccessOutput(barId) {
widthProgressBar = 0;
startProgress(barId);
$.ajax({
url: '/echo/js/?js=hello%20world!',
complete: function(response) {
widthProgressBar = 99;
},
error: function() {
widthProgressBar = 99;
},
});
return false;
}
function startProgress(barId) {
var elem = document.getElementById(barId);
var widthProgressBar = elem.style.width.slice(0, -4);
var id = setInterval(frame, 15);
function frame() {
if (widthProgressBar >= 90 && widthProgressBar < 99) {}
if (widthProgressBar >= 100) {
clearInterval(id);
} else {
widthProgressBar++;
elem.style.width = widthProgressBar + '%';
elem.innerHTML = widthProgressBar * 1 + '%';
}
}
}
.testProgress {
width: 100%;
background-color: #ddd;
}
.testProgressBar {
width: 0%;
height: 30px;
background-color: #4CAF50;
text-align: center;
line-height: 30px;
color: white;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
test success ||
<div class="testProgress">
<div id="pingTestBar" class="testProgressBar"></div>
</div>
By passing an argument to startProgress(barId) you can use the same function for different bars.
// handles the click event, sends the query
function getSuccessOutput(barId) {
widthProgressBar = 0;
startProgress(barId);
$.ajax({
url: '/echo/js/?js=hello%20world!',
complete: function(response) {
widthProgressBar = 99;
},
error: function() {
widthProgressBar = 99;
},
});
return false;
}
function startProgress(barId) {
var elem = document.getElementById(barId);
var widthProgressBar = elem.style.width.slice(0, -4);
var id = setInterval(frame, 15);
function frame() {
if (widthProgressBar >= 90 && widthProgressBar < 99) {}
if (widthProgressBar >= 100) {
clearInterval(id);
} else {
widthProgressBar++;
elem.style.width = widthProgressBar + '%';
elem.innerHTML = widthProgressBar * 1 + '%';
}
}
}
.testProgress {
width: 100%;
background-color: #ddd;
}
.testProgressBar {
width: 0%;
height: 30px;
background-color: #4CAF50;
text-align: center;
line-height: 30px;
color: white;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
test success ||
test success2
<div class="testProgress">
<div id="pingTestBar" class="testProgressBar"></div>
</div>
<div class="testProgress">
<div id="pingTestBar2" class="testProgressBar"></div>
</div>

[cut] There are at least three problems in my solution:
I have to reset progress bar 'width' in 3 places
I must have public
variable (widthProgressBar)
I cannot reuse function 'startProgress' in
case I want to have two progress bars at same page.
Simply initialize/reset once when getSuccessOutput() starts
Use the width attribute stored on each bar
Pass the "bar" as arguments, so you can use many bars as you need.
Anyway, you could use .animate() in order to show the progress, so you avoid to keep interval id and the code is more readable.
Please, take a look to following snippet:
function getSuccessOutput() {
//Reset all progress bars
$(".testProgressBar").width(0);
$(".testProgressBar").text("");
//Start requests
doRequest($("#pingTestBar"), 1200);
doRequest($("#pingTestBar2"), 1500);
doRequest($("#pingTestBar3"), 800);
}
function startProgress(bar) {
bar.animate(
{
width:'100%'
},
{
step: function() {
setText(bar);
},
duration: 2000
}
);
}
function complete(bar) {
console.log("Complete " + bar.attr('id'));
bar.finish().animate(
{
width:'100%'
},
{
step: function(){
setText(bar);
}
}
);
}
function setText(bar){
var text = bar.width() / bar.parent().width() * 100;
bar.text(text.toFixed(0));
}
function mockAjax(options) {
var that = {
done: function done(callback) {
if (options.success)
setTimeout(callback, options.timeout, options.response);
return that;
},
error: function error(callback) {
if (!options.success)
setTimeout(callback, options.timeout, options.response);
return that;
}
};
return that;
}
function doRequest(bar, duration){
var mock = {
ajax: function() {
return mockAjax({
success: true,
response: {},
timeout: duration
});
}
};
startProgress(bar);
mock.ajax()
.done(
function (response) {
complete(bar);
}
)
.error(
function (response) {
complete(bar);
}
);
}
.testProgress {
width: 100%;
background-color: #ddd;
}
.testProgressBar {
width: 0%;
height: 30px;
background-color: #4CAF50;
text-align: center;

Make all div.obstacles have the same function

I am making a simple game that if the characters touch the "obstacle" which is another div the character that touches it will slow down while they are collided.
I already have a code for this, but it is only working for my .obstacle1 div even if I tried using jquery.each or I'm just missing something.
Here is the code which is working only for .obstacle1
HTML
<div class="field">
<div id="char1" class="characters character1">char1</div>
<div id="char2" class="characters character2">char2</div>
<div id="char3" class="characters character3">char3</div>
<div class="obstacles obstacle1">1</div>
<div class="obstacles obstacle2">2</div>
</div>

}
.field-container {

Here is my fiddle.

Here's a fiddle with my suggested fix:
https://jsfiddle.net/40evn8pr/
The problem is that you're 'flattening' the obstacles jquery selection to a single value when you're directly asking for its offset/width/height. You should ask every element from the jquery selection what its offset is with an '$.each' loop to have every obstacle work.
$(document).ready(function(){
intervalCharacters = setInterval(function(){
moveChar();
},100);
function moveChar() {
$(".characters").each(function(){
move($(this));
});
}
var position = ["first","second","third"];
var counter = 0;
function checkIfFinish(thisChar) {
var position2 = position[counter];
counter++;
$(".result").append("<br>Position"+position2+ " counter" + counter + " : " + thisChar.attr("id"));
if(counter >= 3) {
clearInterval(interval);
}
}
/*--------------
OBSTACLES
---------------*/
var obstacle1 = $(".obstacles");
function checkIfCollidesChar(thisChar) {
var thisCharPosX = thisChar.offset().left;
var thisCharPosY = thisChar.offset().top;
var thisCharWidth = thisChar.outerWidth();
var thisCharHeight = thisChar.outerHeight();
var totalCharY = thisCharPosY + thisCharHeight;
var totalCharX = thisCharPosX + thisCharWidth;
var isCollision = false;
$.each(obstacle1, function(i, ob) {
var obstacle1CurrentPosX = $(ob).offset().left;
var obstacle1CurrentPosY = $(ob).offset().top;
var obstacle1Height = obstacle1.outerHeight();
var obstacle1Width = obstacle1.outerWidth();
var totalY = obstacle1CurrentPosY + obstacle1Height;
var totalX = obstacle1CurrentPosX + obstacle1Width;
if (!(totalY < thisCharPosY || obstacle1CurrentPosY > totalCharY || totalX < thisCharPosX || obstacle1CurrentPosX > totalCharX)) {
isCollision = true;
}
});
return isCollision;
}
/* -----
move the characters
---- */
var moveFromLeft = 0;
var maxPosition = 1500;
function move(thisChar) {
var _this = thisChar;
var currentPosition = _this.offset().left;
var charSpeed = Math.floor(Math.random() * (10 - 0 + 1)) + 0;
if(checkIfCollidesChar(_this)) {
if(_this.offset().left > maxPosition) {
moveFromLeft = maxPosition;
}else{
moveFromLeft = currentPosition + (charSpeed*.25);
}
}else{
if(_this.offset().left > maxPosition) {
moveFromLeft = maxPosition;
}else{
moveFromLeft = currentPosition + charSpeed;
}
}
_this.css({
"left" : moveFromLeft,
});
if(moveFromLeft > maxPosition) {
checkIfFinish(_this);
_this.css({
"left" : maxPosition+"px",
});
}
_this.html(moveFromLeft);
}
});

I think you are almost good. For your loop, you can use as model the
$(".characters").each(function(){
move($(this));
});
In your case, this would give :
$(".obstacles").each(function(){
var obstacle1 = $(this)
var obstacle1CurrentPosX = obstacle1.offset().left;
var obstacle1CurrentPosY = obstacle1.offset().top;
var obstacle1Height = obstacle1.outerHeight();
var obstacle1Width = obstacle1.outerWidth();
var totalY = obstacle1CurrentPosY + obstacle1Height;
var totalX = obstacle1CurrentPosX + obstacle1Width;
...
});

Javascript end game when click on image

Hey this is my first time on Stackoverflow!
I am building a small javascript html5 game where you click on objects kind of like whack-a-mole.. The goal is to kill as many "gem green" and " gem blue" as possible in 10 seconds, and when you click on the "gem red".. the game ends and plays a sound.
I got most things to work, except I can't find a way to make the game end when clicking on "gem red".. I have tried lots of functions and listeners.. but to no avail.. can anyone help me figure this out?

Alessio -
You only need a few minor changes to your code to make it work. The example below should help you get started in the right direction. Good luck.
Changes:
Add an endGame() function and move the stop game logic from the timer() function into it.
Add a line to the click() function to check for red gem clicks.
if (target.className.indexOf('red') > 0) endGame("Red Gem - You win!");
Declare the count, counter, and interval variables at the top of your Game object.
The code below also has a few minor CSS changes used for debugging which you can remove.

For starters, you shouldn't include a style sheet and your entire HTML file since neither is relevant and you should use a canvas element instead of this chaotic use of CSS and html elements, which would allow the size of your code to be halved. Furthermore, you should be able to fix this by just changing some global boolean variable to false when the red gem is clicked and when the boolean variable is false (this if statement belongs at the end of your game loop) you call Stop(arg)/clearInterval(arg). Given that your current code doesn't seem to have a global boolean variable indicating game state (using an enumeration would generally be a cleaner solution but a simple boolean seems to suit this case)
