Stop loop iterations of functions with setTimeout

My problem is when I hover over something really fast, it executes the first function and then the second function when the mouse leave the text. The two functions are executed completely. I would like something like, if the mouse leave before a specific time, do something. For instance, change the text to "Fr"
$( "#nav6" ).hover(
function() {
navsix(6);
}, function() {
<!-- clearTimeout(TO) -->
nav6out(6);
}
);
function navsix(i) {
if (window.matchMedia("(min-width: 600px)").matches) {
var elem = document.getElementById("nav6");
var str = "Français";
var len = str.length + 1 - i;
var TO = setTimeout(function () {
elem.innerHTML = str.substring(0, len);
if (--i) navsix(i);
}, 50)
}
}
function nav6out(i) {
if (window.matchMedia("(min-width: 600px)").matches) {
var elem = document.getElementById("nav6");
var str = "Français";
len = i + 1
var TO = setTimeout(function () {
elem.innerHTML = str.substring(0, len);
if (--i) nav6out(i);
}, 50)
}
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="topnav-right"><a id="nav6" href="#Francais">Fr</a></div>

You're on the right track with clearTimeout(). I added clearTimeout() right before each of your setTimeout() functions and declared TO at the top.
var TO = "";
var hoverTimeout = "";
$("#nav6").hover(
function() {
hoverTimeout = setTimeout(function() {
navsix(6);
}, 200)
},
function() {
clearTimeout(hoverTimeout);
nav6out(6);
}
);
function navsix(i) {
if (window.matchMedia("(min-width: 600px)").matches) {
var elem = document.getElementById("nav6");
var str = "Français";
var len = str.length + 1 - i;
clearTimeout(TO);
TO = setTimeout(function() {
elem.innerHTML = str.substring(0, len);
if (--i) navsix(i);
}, 50)
}
}
function nav6out(i) {
if (window.matchMedia("(min-width: 600px)").matches) {
var elem = document.getElementById("nav6");
var str = "Français";
if (elem.innerHTML.length > 2) {
len = i + 1;
clearTimeout(TO);
TO = setTimeout(function() {
elem.innerHTML = str.substring(0, len);
if (--i) nav6out(i);
}, 50)
}
}
}

Combining two Javascript functions to one window.onload not working

I have two functions that I want to run on window.onload event but only the last function seems to work so far. One function is for an image slider and the other one retrieves data from a google spreadsheet cell.
function fun1() { //image slider
var ul;
var li_items;
var imageNumber;
var imageWidth;
var prev, next;
var currentPostion = 0;
var currentImage = 0;
function init() {
ul = document.getElementById('image_slider');
li_items = ul.children;
imageNumber = li_items.length;
imageWidth = li_items[0].children[0].clientWidth;
ul.style.width = parseInt(imageWidth * imageNumber) + 'px';
prev = document.getElementById("prev");
next = document.getElementById("next");
prev.onclick = function() {
onClickPrev();
};
next.onclick = function() {
onClickNext();
};
}
function animate(opts) {
var start = new Date;
var id = setInterval(function() {
var timePassed = new Date - start;
var progress = timePassed / opts.duration;
if (progress > 1) {
progress = 1;
}
var delta = opts.delta(progress);
opts.step(delta);
if (progress == 1) {
clearInterval(id);
opts.callback();
}
}, opts.delay || 17);
}
function slideTo(imageToGo) {
var direction;
var numOfImageToGo = Math.abs(imageToGo - currentImage);
direction = currentImage > imageToGo ? 1 : -1;
currentPostion = -1 * currentImage * imageWidth;
var opts = {
duration: 1000,
delta: function(p) {
return p;
},
step: function(delta) {
ul.style.left = parseInt(currentPostion + direction * delta * imageWidth * numOfImageToGo) + 'px';
},
callback: function() {
currentImage = imageToGo;
}
};
animate(opts);
}
function onClickPrev() {
if (currentImage == 0) {
slideTo(imageNumber - 1);
} else {
slideTo(currentImage - 1);
}
}
function onClickNext() {
if (currentImage == imageNumber - 1) {
slideTo(0);
} else {
slideTo(currentImage + 1);
}
}
}
function fun2() {
// Google spreadsheet js
google.load('visualization', '1', {
callback: function() {
var query = new google.visualization.Query('https://docs.google.com/spreadsheets/d/1sA7M5kG6Xo8YScD1Df38PIA_G0bvhGRdqoExXg0KJTs/gviz/tq?tqx=out:html&tq?gid=0&headers=0&range=A1:C');
query.send(displayData);
}
});
function displayData(response) {
numRows = response.getDataTable().getValue(0, 0);
document.getElementById('data').innerHTML = numRows;
}
}
var addFunctionOnWindowLoad = function(callback) {
if (window.addEventListener) {
window.addEventListener('load', callback, false);
} else {
window.attachEvent('onload', callback);
}
}
addFunctionOnWindowLoad(fun1);
addFunctionOnWindowLoad(fun2);
This is the answer I've tried link but I can't seem to figure out where I'm going wrong.

This is what I ended up doing, and now all the functions work.
var ul;
var li_items;
var imageNumber;
var imageWidth;
var prev, next;
var currentPostion = 0;
var currentImage = 0;
function init() {
ul = document.getElementById('image_slider');
li_items = ul.children;
imageNumber = li_items.length;
imageWidth = li_items[0].children[0].clientWidth;
ul.style.width = parseInt(imageWidth * imageNumber) + 'px';
prev = document.getElementById("prev");
next = document.getElementById("next");
prev.onclick = function() {
onClickPrev();
};
next.onclick = function() {
onClickNext();
};
}
function animate(opts) {
var start = (new Date());
var id = setInterval(function() {
var timePassed = (new Date()) - start;
var progress = timePassed / opts.duration;
if (progress > 1) {
progress = 1;
}
var delta = opts.delta(progress);
opts.step(delta);
if (progress == 1) {
clearInterval(id);
opts.callback();
}
}, opts.delay || 17);
//return id;
}
function slideTo(imageToGo) {
var direction;
var numOfImageToGo = Math.abs(imageToGo - currentImage);
// slide toward left
direction = currentImage > imageToGo ? 1 : -1;
currentPostion = -1 * currentImage * imageWidth;
var opts = {
duration: 1000,
delta: function(p) {
return p;
},
step: function(delta) {
ul.style.left = parseInt(currentPostion + direction * delta * imageWidth * numOfImageToGo) + 'px';
},
callback: function() {
currentImage = imageToGo;
}
};
animate(opts);
}
function onClickPrev() {
if (currentImage === 0) {
slideTo(imageNumber - 1);
} else {
slideTo(currentImage - 1);
}
}
function onClickNext() {
if (currentImage == imageNumber - 1) {
slideTo(0);
} else {
slideTo(currentImage + 1);
}
}
window.onload = init;
function addLoadEvent(func) {
var oldonload = window.onload;
if (typeof window.onload != 'function') {
window.onload = func;
} else {
window.onload = function() {
if (oldonload) {
oldonload();
}
func();
}
}
}
function fun2() {
// Google spreadsheet js
google.load('visualization', '1', {
callback: function() {
var query = new google.visualization.Query('https://docs.google.com/spreadsheets/d/1sA7M5kG6Xo8YScD1Df38PIA_G0bvhGRdqoExXg0KJTs/gviz/tq?tqx=out:html&tq?gid=0&headers=0&range=A1:C');
query.send(displayData);
}
});
function displayData(response) {
numRows = response.getDataTable().getValue(0, 0);
document.getElementById('data').innerHTML = numRows;
}
}
addLoadEvent(fun2);
addLoadEvent(function() {
});

I found this function a while ago and believe it or not, I still need to use it every so often. addEventLoad() Just call addEventLoad while passing the function to load.
"The way this works is relatively simple: if window.onload has not already been assigned a function, the function passed to addLoadEvent is simply assigned to window.onload. If window.onload has already been set, a brand new function is created which first calls the original onload handler, then calls the new handler afterwards."
This snippet will load 3 functions on window.onload
Snippet
function addLoadEvent(func) {
var oldonload = window.onload;
if (typeof window.onload != 'function') {

oldonload();
}
func();
}
}
}
function alert1() {
alert("First Function Loaded");
}
function alert2() {
alert("Second Function Loaded");

function alert3(str) {
alert("Third Function Loaded; Msg: " + str);
}
addLoadEvent(alert1);
addLoadEvent(alert2);
addLoadEvent(function() {

Toggle class on HTML element without jQuery

I have a section on my website which holds all the content, but I want a "sidebar" with hidden content to smoothly appear from the left at the push of an external button.
CSS transitions can handle the smoothness no problem, and jQuery toggle() can switch between classes to move the hidden div in and out of the screen.
How can I get the same effect without using jQuery?

You can toggle classes using the classList.toggle() function:
var element = document.getElementById('sidebar');
var trigger = document.getElementById('js-toggle-sidebar'); // or whatever triggers the toggle
trigger.addEventListener('click', function(e) {
e.preventDefault();
element.classList.toggle('sidebar-active'); // or whatever your active class is
});
That should do everything you need - if you have more than one trigger I'd recommend using document.querySelectorAll(selector) instead.

You can implement it only by CSS3:
<label for="showblock">Show Block</label>
<input type="checkbox" id="showblock" />
<div id="block">
Hello World
</div>
And the CSS part:
#block {
background: yellow;
height: 0;
overflow: hidden;
transition: height 300ms linear;
}
label {
cursor: pointer;
}
#showblock {
display: none;
}
#showblock:checked + #block {
height: 40px;
}
The magic is the hidden checkbox and the :checked selector in CSS.
Working jsFiddle Demo.

HTML ONLY
You can use <summary>. The following code doesn't have any dependency.
No JavaScript, CSS at all, HTML only.
<div class="bd-example">
<details open="">
<summary>Some details</summary>
<p>More info about the details.</p>
</details>
<details>
<summary>Even more details</summary>
<p>Here are even more details about the details.</p>
</details>
</div>
For more detail, go to MDN official docs.

you can get any element by id with javascript (no jquery) and the class is an attribute :
element.className
so have this as a function:
UPDATE:
since this is becoming a somewhat popular I updated the function to make it better.
function toggleClass(element, toggleClass){
var currentClass = element.className || '';
var newClass;
if(currentClass.split(' ').indexOf(toggleClass) > -1){ //has class
newClass = currentClass.replace(new RegExp('\\b'+toggleClass+'\\b','g'), '')
}else{
newClass = currentClass + ' ' + toggleClass;
}
element.className = newClass.trim();
}

left: function (timePercent, frame) {
var endPoint = 128,
startPoint = 0,
pathLength = endPoint - startPoint,
base = 64, //slope of the curve
currentPos = Math.floor(startPoint + (Math.pow(base, timePercent) - 1) / (base - 1) * pathLength);
return currentPos + "px";
}

element.style.left = "128px";

Jquery stopped working

I'm developping this mobile app and I'm usint this (https://github.com/krisrak/appframework-templates/blob/master/template-CarouselViewApp.html) as a carousel to change through content on a page. http://jsfiddle.net/nafis56/qCkqb/
So for this I need to mess around in HTML, CSS and Jquery. Unfortonetly I'm still very green at javascript so I need your help. I changed an ID to a Class because I need to call it more than once in the same page. In the original template I refeered to, it comes as an ID. So I did this to change it:
Changed matching code on html to call it as a Class.
<div class="panel" title="Desiree Charms" id="desiree_charms" style="overflow: hidden;"
data-appbuilder-object="page">
<div class="carousel">
<div class="carousel_page">
<h2>Desiree Charms</h2>
<p><img src="images/desiree_charms.jpg" style="width: 85%; height: 85%; display: block; margin-left: auto; margin-right: auto "
data-appbuilder-object="image" class="" title="">
</p>
</div>
<div class="carousel_page">
<h2>Page Two</h2>
<p>Text and images for Page Two goes here. Swipe to go to the
next page.</p>
</div>
</div>
<div class="carousel_dots"></div>
</div>
also this on the html.
<script>
$.ui.autoLaunch = false;
$.ui.animateHeaders = false;
$(document).ready(function(){
$.ui.launch();
});
$.ui.ready(function(){
carouselSetup();
});
function carouselSetup(){
// set size of carousel
$(".carousel").width($(".carousel").closest(".panel").width());
$(".carousel").height($(".carousel").closest(".panel").height()-25);
var options={
vertical:false, // page up/down
horizontal:true, // page left/right
pagingDiv:"carousel_dots", // div to hold the dots for paging
pagingCssName:"carousel_paging", //classname for the paging dots
pagingCssNameSelected: "carousel_paging_selected", //classname for the selected page dots
wrap:true //Creates a continuous carousel
}
var carousel = $(".carousel").carousel(options);
}
Changed # to . on Css.
.carousel {
overflow:hidden;
margin:0 -10px;
}
.carousel_page {
overflow: auto;
-webkit-scrolling:touch;
padding:0 10px;
}
.carousel_dots {

margin-right: auto;
clear: both;

Now, on the CSS file when I change .carousel_dots to #carousel_dots as it was originally. The carousel starts working. The problem is I need it as a class not an ID.
I'm pretty sure the problem is in the jquery, somewhere in there I need to set carousel_dots as a class and not an ID, but where?
Any help will be much apreciated, thanks.

jQuery is designed to trigger on HTML selectors, either elements, ID's or Class's. It's very common for it to trigger on ID's because, as you identified, they occur once and that isolates the action to that particular item.
I know that you changed the ID's to Class's because you want to use the CSS class multiple times. You can do this by using Class's. But, to maintain the jQuery logic, you should not change the ID's to Class's for that purpose. Use the ID's to synch with jQuery. Use Class's to control your CSS.
It's difficult to advise you regarding the case you displayed because you didn't identify the initial status and exactly how you changed it. If you can do that, we can be specific about what changes you should make. Good luck.

I want to make countdown then capatcha

Hi
I got countdown code
<script type="text/javascript">
window.onload = function() {
countDown('my_div1', '<form>1+1=<input name="d" type="text" /></form>', 10);
}
function countDown(elID, output, seconds) {
var elem = document.getElementById(elID),
start = new Date().getTime(), end = start+seconds*1000,
timer = setInterval(function() {
var now = new Date().getTime(), timeleft = end-now, timeparts;
if( timeleft < 0) {
elem.innerHTML = output;
clearInterval(timer);
}
else {
timeparts = [Math.floor(timeleft/60000),Math.floor(timeleft/1000)%60];
if( timeparts[1] < 10) timeparts[1] = "0"+timeparts[1];
elem.innerHTML = "Time left: "+timeparts[1];
}
},250);
}
</script>
I want when the countdown end appear CAPTCHA or question if this right, then continue to link

try to put the countdown function here
window.onload = function() {
countDown('my_div1', //here// , 10);
}

Assume that your countdown coding is working fine and you have a div in which captcha is stored say div id = "captchadiv",
<script type="text/javascript">
window.onload = function() {
//////////////////////////////////////////////////////
set the visibility of the captcha hidden here.
//////////////////////////////////////////////////////
countDown('my_div1', '<form>1+1=<input name="d" type="text" /></form>', 10);
}
function countDown(elID, output, seconds) {
var elem = document.getElementById(elID),
start = new Date().getTime(), end = start+seconds*1000,
timer = setInterval(function() {
var now = new Date().getTime(), timeleft = end-now, timeparts;
if( timeleft < 0) {
elem.innerHTML = output;
clearInterval(timer);
//////////////////////////////////////////////////////
set visibility of captchadiv to visibile.
//////////////////////////////////////////////////////
}
else {
timeparts = [Math.floor(timeleft/60000),Math.floor(timeleft/1000)%60];
if( timeparts[1] < 10) timeparts[1] = "0"+timeparts[1];
elem.innerHTML = "Time left: "+timeparts[1];
}
},250);
}
//////////////////////////////////////////////////////
add a function here to validate the captcha.
If validation succeeds, do success action.
If validation fails, set captcha visibility to hidden and again call the counttDown function.
