ReactJS: element.ScrollLeft does not change value after resizing window

I have a state called scrollStatus, where I track the current scroll position of a div, and I set its value using a ref and element.scrollLeft when scrolling:
const scrollHandle = () => {
setScrollStatus(container.current?.scrollLeft);
console.log(scrollStatus);
}
So when doing console.log I get a different value of scrollStatus, which is what I want:
When I resize the window by a large margin (let's say from desktop to mobile view), the scroll value will change drastically, which I expected for it to happen since my container's width is percentage based.
Here in the console, you can see the value changed to 375 after I resize the window to mobile view:
However, when I try to scroll again after resizing the window, the value of scrollStatus doesn't change. It retains the current position value after I resize the window:
(The value still won't change even if I resize the window again)
Any idea what's going on here and how to fix it?

setting top and left with offset()

I am trying to position an element using offset() but I'm not sure what is going on:
This is default offset position:
element.offset().top
‌770
element.offset().left
‌1822.796875
Then I try setting it manually
element.offset({top: 674, left: 1722 })
And the output:
element.offset().top
‌-1341
element.offset().left
1722
Top position is -1341 ? and then I tried setting just top property:
element.offset({top:674})
element.offset().top
‌674
and this works ? What is going on, why I can't set both properties at the same time?
UPDATE: I just figured that this might be important: there is also iframe element on the page that has a scrollbar. So everything with offfset work fine, until I scroll down the window of the iframe element. But after scrolling down and then calling offset() it works.

Since there is no shared fiddle, I'm assuming your scenario.
Assuming your element is hidden and you are setting its offset and then making it as visible. in this case your offset settings will not work.
Try to follow these steps.
Make that element visible. (maybe by using element.show())
Set the offset now.

jQuery/JS, iOS 4 and $(document).height() problems

I've run into an odd issue with what appears to be various versions of Webkit browsers. I'm trying to position an element on the center of the screen and to do the calculations, I need to get various dimensions, specifically the height of the body and the height of the screen. In jQuery I've been using:
var bodyHeight = $('body').height();
var screenHeight = $(window).height();
My page is typically much taller than the actual viewport, so when I 'alert' those variables, bodyHeight should end up being large, while screenHeight should remain constant (height of the browser viewport).
This is true in
- Firefox
- Chrome 15 (whoa! When did Chrome get to version 15?)
- Safari on iOS5
This is NOT working in:
- Safari on iOS4
- Safari 5.0.4
On the latter two, $(window).height(); always returns the same value as $('body').height()
Thinking it was perhaps a jQuery issue, I swapped out the window height for window.outerHeight but that, too, does the same thing, making me think this is actually some sort of webkit problem.
Has anyone ran into this and know of a way around this issue?
To complicate things, I can't seem to replicate this in isolation. For instance: http://jsbin.com/omogap/3 works fine.
I've determined it's not a CSS issue, so perhaps there's other JS wreaking havoc on this particular browser I need to find.

I've been fighting with this for a very long time (because of bug of my plugin) and I've found the way how to get proper height of window in Mobile Safari.
It works correctly no matter what zoom level is without subtracting height of screen with predefined height of status bars (which might change in future). And it works with iOS6 fullscreen mode.
Some tests (on iPhone with screen size 320x480, in landscape mode):
// Returns height of the screen including all toolbars
// Requires detection of orientation. (320px for our test)
window.orientation === 0 ? screen.height : screen.width
// Returns height of the visible area
// It decreases if you zoom in
window.innerHeight
// Returns height of screen minus all toolbars
// The problem is that it always subtracts it with height of the browser bar, no matter if it present or not
// In fullscreen mode it always returns 320px.
// Doesn't change when zoom level is changed.
document.documentElement.clientHeight
Here is how height is detected:
var getIOSWindowHeight = function() {
// Get zoom level of mobile Safari
// Note, that such zoom detection might not work correctly in other browsers
// We use width, instead of height, because there are no vertical toolbars :)
var zoomLevel = document.documentElement.clientWidth / window.innerWidth;
// window.innerHeight returns height of the visible area.
// We multiply it by zoom and get out real height.
return window.innerHeight * zoomLevel;
};
// You can also get height of the toolbars that are currently displayed
var getHeightOfIOSToolbars = function() {
var tH = (window.orientation === 0 ? screen.height : screen.width) - getIOSWindowHeight();
return tH > 1 ? tH : 0;
};
Such technique has only one con: it's not pixel perfect when page is zoomed in (because window.innerHeight always returns rounded value). It also returns incorrect value when you zoom in near top bar.
One year passed since you asked this question, but anyway hope this helps! :)

I had a similar problem. It had to do with 2 thing:
Box-sizing CSS3 property:
In the .height() jQuery documentation I found this:
Note that .height() will always return the content height, regardless of the value of the CSS box-sizing property. As of jQuery 1.8, this may require retrieving the CSS height plus box-sizing property and then subtracting any potential border and padding on each element when the element has box-sizing: border-box. To avoid this penalty, use .css( "height" ) rather than .height().
This may apply to $('body').height().
Document ready vs Window.load
$(document).ready() is run when the DOM is ready for JS but it's possible that images haven't finished loading yet. Using $(window).load() fixed my problem. Read more.
I hope this helps.

It is 2015, we are at iOS 8 now. iOS 9 is already around the corner. And the issue is still with us. Sigh.
I have implemented a cross-browser solution for the window size in jQuery.documentSize. It stays clear of any kind of browser sniffing and has been heavily unit-tested. Here's how it works:
Call $.windowHeight() for the height of the visual viewport. That is the height of the area you actually see in the viewport at the current zoom level, in CSS pixels.
Call $.windowHeight( { viewport: "layout" } ) for the height of the layout viewport. That is the height which the visible area would have at 1:1 zoom - the "original window height".
Just pick the appropriate viewport for your task, and you are done.
Behind the scenes, the calculation roughly follows the procedure outlined in the answer by #DmitrySemenov. I have written about the steps involved elsewhere on SO. Check it out if you are interested, or have a look at the source code.

Try this :
var screenHeight = (typeof window.outerHeight != 'undefined')?Math.max(window.outerHeight, $(window).height()):$(window).height()

A cross browser solution is set that by jQuery
Use this property:
$(window).height()
This return a int value that represents the size of visible screen height of browser in pixels.

Using Javascript to resize a div to screen height causes flickering when shrinking the browser window

The Background:
I tried to solve the StackOverflow question yet another HTML/CSS layout challenge - full height sidebar with sticky footer on my own using jQuery. Because the sidebar in my case may be longer than the main content it matches the case of comment 8128008. That makes it impossible to have a sidebar longer than the main content and having a sticky footer without getting problems when shrinking the browser window.
The status quo:
I have a html page with a div, which is automatically stretched to fill the screen. So if there is empty space below the element, I stretch it downwards:
But if the browser viewport is smaller than the div itself, no stretching is done but the scrollbar shows up:
I've attached jQuery to the window's resize event to resize the div, if the browser window is not to small and remove any resizing in the other case. This is done by checking if the viewport is higher or smaller than the document. If the viewport is smaller than the document, it seems like the content is larger than the browser window, why no resizing is done; in the other case we resize the div to fill the page.
if ($(document).height() > $(window).height()) {
// Scrolling needed, page content extends browser window
// --> No need to resize the div
// --> Custom height is removed
// [...]
} else {
// Window is larger than the page content
// --> Div is resized using jQuery:
$('#div').height($(window).height());
}
The Problem:
Up to now, everything runs well. But if I shrink the browser window, there are cases, where the div should be resized but the document is larger than the window's height, why my script assumes, that no resizing is needed and the div's resizing is removed.
The point is actually, that if I check the document's height using Firebug after the bug appeared, the height has just the value is was meant to have. So I thought, the document's height is set with a little delay. I tried to run the resize code delayed a bit but it did not help.
I have set up a demonstration on jsFiddle. Just shrink the browser window slowly and you'll see the div "flickering". Also you can watch the console.log() output and you will notice, that in the case of "flickering" the document's height and the window's height are different instead of being equal.
I've noticed this behavior in Firefox 7, IE 9, Chrome 10 and Safari 5.1. Can you confirm it?
Do you know if there is a fix? Or is the approach totally wrong? Please help me.

Ok -- wiping my old answer and replacing...
Here's your problem:
You are taking and comparing window and document height, without first taking into consideration the order of events here..
Window loads
Div grows to window height
Window shrinks
Document height remains at div height
Window height is less than div height
At this point, the previously set height of the div is keeping document height greater than the window height, and this logic is misinterpreted:
"Scrolling needed, no need to extend the sidebar" fires, erroneously
Hence the twitch.
To prevent it, just resize your div along with the window before making the comparison:
(function () {
var resizeContentWrapper = function () {
console.group('resizing');
var target = {
content: $('#resizeme')
};
//resize target content to window size, assuming that last time around it was set to document height, and might be pushing document height beyond window after resize
//TODO: for performance, insert flags to only do this if the window is shrinking, and the div has already been resized
target.content.css('height', $(window).height());
var height = {
document: $(document).height(),
window: $(window).height()
};
console.log('height: ', height);
if (height.document > height.window) {
// Scrolling needed, no need to externd the sidebar
target.content.css('height', '');
console.info('custom height removed');
} else {
// Set the new content height
height['content'] = height.window;
target.content.css('height', height['content']);
console.log('new height: ', height);
}
console.groupEnd();
}
resizeContentWrapper();
$(window).bind('resize orientationchange', resizeContentWrapper);
})(jQuery);
Per pmvdb's comment, i renamed your $$ to "target"

$(window).bind('resize',function(){
$("#resizeme").css("height","");
if($("#resizeme").outerHeight() < $(window).height()){
$("#resizeme").height($(window).height());
$("body").css("overflow-y","hidden");
}else{
$("body").css("overflow-y","scroll");
}
});

Maybe I am misunderstanding the problem, but why are you using Javascript? This seems like a layout (CSS) issue. My solution without JS: http://jsfiddle.net/2yKgQ/27/

How do I find the current window offset using javascript?

When I open a page, the window offset would be 0 but when i scroll through the page, the offset of the window would increase correspondingly? How can I find the window's offset at any particular point of my web page?

You can get the scroll offset of the window by using window.scrollX & window.scrollY. See the MDN article on scrollY for more information.
window.scrollY; // the current vertical scroll offset of the window
Just thought I would provide the non-jQuery version.

I don't know if I get the question, but for getting scroll offset use:
var scrollOffset = $(window).scrollTop();

The .offset() method is undefined for window object or window element therefore you
should use the .scrollTop() method to solve your issue :)
