Progress bar - jQuery to Pure Vanilla JS

I am trying to convert this small script to a pure vanilla JS.
The plain JS values are not calculated correctly.
What do I need to get to calculate the same value as in the jQuery version?
Pleaset scroll down in the jQuery fiddle to see what l mean.
$(document).scroll(function() {
var progressBar = $('progress'),
docHeight = $(this).height(),
winHeight = $(window).height(),
max = docHeight - winHeight,
value = $(window).scrollTop();
progressBar.attr('max', max);
progressBar.attr('value', value);
});
DEMO jQuery
And below, my pure JS which doesn't work :
var progressBar = function() {
var myBar = document.querySelector('progress'),
docHeight = document.clientHeight,
winHeight = window.clientHeight,
max = docHeight - winHeight,
value = window.scrollY;
myBar.setAttribute('data-max', myBar.getAttribute('max'));
myBar.setAttribute('max', max);
myBar.setAttribute('data-value', myBar.getAttribute('value'));
myBar.setAttribute('value', value);
};
document.addEventListener('scroll', progressBar);
window.addEventListener('resize', progressBar);
My attempt in vanilla
Thank you!!

You'll need to use different properties to access the document and window heights.
document.clientHeight should be document.body.clientHeight. The clientHeight property is designed to return the calculated heights of HTML elements. Using the body element fits within that design.
window.clientHeight should be window.innerHeight. Since window isn't an HTML element, it has its own height properties.
I also simplified the progress bar attribute-setting logic. Unless you have some external requirement to set the data-max and data-value attributes, you can remove those lines. If you do need to set those attributes, you can use the dataset property.
var progressBar = function() {
var myBar = document.querySelector('progress'),
docHeight = document.body.clientHeight,
winHeight = window.innerHeight,
max = docHeight - winHeight,
value = window.scrollY;
myBar.setAttribute('max', max);
myBar.setAttribute('value', value);
};
document.addEventListener('scroll', progressBar);
window.addEventListener('resize', progressBar);
See JSFiddle.

The clientHeight property doesn't exist on window or document. If you have a look at the JQuery docs:
$(window).height() returns height of browser viewport
$(document).height() returns the height of HTML document
There already a great answer on StackOverflow explaining the different ways to get the height. Looking at the JQuery source, the height of the window uses window.innerHeight. For the document it's using the max of:
document.body.scrollHeight
document.body.offsetHeight
document.documentElement.clientHeight
Putting it all together, it works AOK: https://jsfiddle.net/pd3dtvxn/7/

Get, set and reset height using browser size and resize

I'm still an amateur when it comes to JS, I would like to get the height of the browser window, and then get it to update on resize. Is this possible? (code below)
$(document).ready(function() {
var winHeight = $(window).height(),
winWidth = $(window).width();
$('#wrap_project_horizontal_gallery').css({
'height' : winHeight - 170
});
});
I've thought about using setInterval but there must be a better way. Thanks very much for the help
EDIT: This needs to happen without a page refresh

You could bind a method to the resize event in the window and recalculate your variables there, or resize the elements that need resizing.
$(document).ready(function(){
$(window).resize(function() {
// your code here
});
});
or using a handler
$(document).ready(function(){
$(window).resize(handle_window_resize);
});
function handle_window_resize() {
// your code here
}

You can use the jQuery .resize() method.
$(window).resize(function() {
var winHeight = $(window).height(),
winWidth = $(window).width();
$('#wrap_project_horizontal_gallery').css({
'height' : winHeight - 170
});
});

Get browser width and height after user resizes the window

Is there any way to get the browser width and height after a user has resized the window. For example if the window is 1920 by 1080 and the user changes the window to 500 by 500 is there any way to get those two new values in JavaScript or jquery?

Pure Javascript answer:
var onresize = function() {
//your code here
//this is just an example
width = document.body.clientWidth;
height = document.body.clientHeight;
}
window.addEventListener("resize", onresize);
This works fine on chrome. However, it works only on chrome. A slightly more cross-browser example is using the event target properties "outerWidth" and "outerHeight", since in this case the event "target" is the window itself. The code would be like this
var onresize = function(e) {
//note i need to pass the event as an argument to the function
width = e.target.outerWidth;
height = e.target.outerHeight;
}
window.addEventListener("resize", onresize);
This works fine in firefox and chrome
Hope it helps :)
Edit: Tested in ie9 and this worked too :)

If you need to know these values to do layout adjustments, I bet you plan on listening to those values. I recommended using the Window.matchmedia() API for that purpose instead.
It is much more performant and is basically the JS equivalent of CSS media queries.
Very quick example of use:
if (window.matchMedia("(max-width: 500px)").matches) {
/* the viewport is less than or exactly 500 pixels wide */
} else {
/* the viewport is more than 500 pixels wide */
}
You can also setup a listener that'll get called every time the state of the matches property changes.
See MDN for description and example of using a listener.

It's possible by listening to resize event.
$(window).resize(function() {
var width = $(window).width();
var height = $(window).height();
})

You can use the JQuery resize() function. Also make sure you add the same resize logic to reload event. If user reloads in the sized window your logic won't work.
$(window).resize(function() {
$windowWidth = $(window).width();
$windowHeight = $(window).height();
});
$(document).ready(function() {
//same logic that you use in the resize...
});

Practically, I use this and it helps me a lot:
var TO = false;
var resizeEvent = 'onorientationchange' in window ? 'orientationchange' : 'resize';
$(window).bind(resizeEvent, function() {
TO && clearTimeout(TO);
TO = setTimeout(resizeBody, 200);
});
function resizeBody(){
var height = window.innerHeight || $(window).height();
var width = window.innerWidth || $(window).width();
alert(height);
alert(width);
}

You can use the resize event, along with the height() and width() properties
$(window).resize(function(){
var height = $(window).height();
var width = $(window).width();
});
See some more examples here

Use jQuery resize method to listen window size change . inside callback you can get height and width.
$(window).resize(function(){
var width = $(window).width();
var height = $(window).height();
});

Simplest way to get real width and height of an element after window resize as the follow:
<div id="myContainer">
<!--Some Tages ... -->
</div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
$(function () {
$(window).resize(function () {
//The below two lines of codes more Important to clear the previous settings to get the current measure of width and height
$('#myContainer').css('height', 'unset');
$('#myContainer').css('width', 'unset');
var element = $('#myContainer');
var height = element.height();
var width = element.width();
//Below two lines will includes padding but not border
var innerHeight = element.innerHeight();
var innerWidth = element.innerWidth();
//Below two lines will includes padding, border but no margin
var outerHeight = element.outerHeight();
var outerWidth = element.outerWidth();
//Below two lines will includes padding, border and margin
var outerHeight = element.outerHeight(true);
var outerWidth = element.outerWidth(true);
});
});
</script>

You can use the event object to get the height and width, I use destructuring assignment and the target points to window:
const handleGetDim = ({ target }) => ({
width: target.innerWidth,
height: target.innerHeight,
});
window.addEventListener('resize', handleGetDim);

Use JQuery to resize container based on window size

I am trying to have a container div resize based on the dimensions of the window. The height to width ratio is the most important aspect here and I want to maximize the size of the container in whichever direction (height or width) that is most constraining given the ratio. I have tried a few things unsuccessfully with this being the most recent:
$(window).load(function() {
var h = $(window).height();
var w = $(window).width();
If((h/w)>0.61){
$('#container').css({'height': h, 'width':h*1.64}); }
else{ $('#container').css({'height': w/1.64, 'width':w}); }
})
What do I need to change to get the window to resize? Is there a better way to approach this?
Thanks in advance for any assistance. I am not at all familiar with javascript/JQuery and have been unable to find any useful info... this thing is driving me nuts...

You want to capture the resize event, so assuming your current code works to your likings
$(document).ready(function() {
$(window).resize(function() {
var h = $(window).height();
var w = $(window).width();
if((h/w)>0.61) {
$('#container').css({'height': h, 'width':h*1.64});
}
else {
$('#container').css({'height': w/1.64, 'width':w});
}
});
});
And let's avoid the capital I on the if

I typically use this:
function resize () {
var w = $(window);
var containerWrap = $('#container-wrap');
containerWrap.css({ width:w.width(), height:w.height()});
}
I'm not sure if that answers your ratio question.
EDIT:
This may be more helpful:
$(document).ready(function () {
var missionWrap = $('#mission-wrap');
var w = $(window);
w.on('load resize',function() {
missionWrap.css({ width:w.width(), height:w.height()});
});
});

javascript: Swap image & onClick

<img src="logo.jpg" class="myImage" alt="Logotyp" />
This is my javascript code:
$(function() {
var windowWidth = $(window).width();
if (windowWidth <= 480) {
$(".myImage").attr("src", "load.jpg");
}
});
The image logo.jpg becomes load.jpg when window width = 480. Works fine. But I want an onClick-function that says when you click load.jpg it becomes logo.jpg again. Can't seem to make it work. Suggestions?

$(".myImage").click(function(){
$(this).attr("src"," logo.jpg");
});

jsBin demo
You can:
create a var windowWidth
create a function "changeImg()" that will handle transformations depending on the windowWidth var value.
Than we use our function changeImg() wherever we want: we can do it also inside a $(window).resize() so the changes will be applied on manual re-size too.
Than on click we play dirty, we fool the windowWidth setting a huge number and call our changeImg function. Fun.
jQuery:
$(function() {
var windowWidth = $(window).width();
function changeImg(){
if (windowWidth <= 480) {
$(".myImage").attr("src", "http://www.rockettheme.com/distribution/download/file.php?avatar=63759_1251026504.jpg");
}else{
$(".myImage").attr("src", "http://screenshots.en.sftcdn.net/blog/en/2009/12/2t_firefox-logo.jpg");
}
}
changeImg();
$(window).resize(function(){
windowWidth = $(window).width(); // grab width while resizeing
changeImg();
});
$('img[alt=Logotyp]').on('click', function(){
windowWidth = 9876; // we fool the windowWidth
changeImg(); // we play dead and call our function :D
});
});

function myAlert() { alert("heelo wrold") };
$(.myImage).setAttribute ("onclick", "myAlert()");
Haven't tried this, but it seems right. ~Ben
