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);

I have a banner image that is only visible when i set a fixed height, i want to make it responsive so the only way i thought of doing that is calculating the height of the image with the width of the window.
the function to calculate the height is: windowWidth/1.845
how do i apply that function to a div css with jquery/javascript?
i tried this function but it didn't work
$(document).ready(function(){
var originalWidth = $( window ).width();
var newHeight = originalWidth/+(1.845)
;
function resize() {
$("#ei-slider").css("height", newHeight);
}
$(".target").each(resize);
$(document).resize(function(){
$("ei-slider").each(resize);
});
});
Try adding () when you call your function resize
$(".target").each(resize());
$(document).resize(function(){
$(".ei-slider").each(resize());
});
Also, you miss the point before ei-slider
And I highly recommend to you to use backstretch jquery plugin.

Why is the image only visible when you set a fixed height? An image would be "responsive" automatically if you were to do this in your CSS.
img {
max-width: 100%;
width: 100%;
}
However if you need to do other things in the resize you probably want to listen for resizes on window and not document.
$(document).ready(function () {
var $window = $(window);
var originalWidth = $window.width();
var newHeight = originalWidth / 1.845;
function resize() {
// This will be .target or .ei-slider based on where it's called.
$(this).css("height", newHeight);
};
$(".target").each(resize);
$window.on('resize', function(){
$(".ei-slider").each(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
});
});
I need to get the height of an image and apply the height to another div. This is easy using
$(window).load(function() {
var img_height = $('#image').height();
$('.some_div').css('height', img_height);
});
however... the image is set to width 100% and changes size when re-sizing the browser window. Is it possible to get the live height of the image?
$(window).resize(function () {
var image_height = $('img').height();
$('div').css({
'height': image_height
});
});
Here's a JSFiddle which uses the Console to report back the image height.
You can use window resize callback
$(window).resize(function(){
var img_height = $('#image').height();
$('.some_div').css('height', img_height);
})
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()});
});
});
I am making a login page in which I use a little javascript and jquery to vertically align the login box.
I also have an event on resize() to put the box in the middle again.
But, with resize(), everytime the user resize the window, the function is fired and this is a kind of ugly :))
So, I would like to know if there is a way to fire the function only on vertical resize.
Thank you
It will fire every time, but you can track the width to check for only vertical resizing:
// track width, set to window width
var width = $(window).width();
// fire on window resize
$(window).resize(function() {
// do nothing if the width is the same
if ($(window).width()==width) return;
// update new width value
width = $(window).width();
// ... your code
});
Instead of comparing heights for each situation where you want to detect vertical resize, you can create reusable events for horizontal and vertical resizing like this:
// Horizontal and vertical window resize events.
(function () {
var win = jQuery(window),
prev_width = win.width(),
prev_height = win.height();
win.on('resize', function () {
var width = win.width(),
height = win.height();
if (width !== prev_width) {
win.trigger('hresize');
}
if (height !== prev_height) {
win.trigger('vresize');
}
prev_width = width;
prev_height = height;
});
})();
That way you can just drop that code in place once, and then use the events like this:
$(window).on('hresize', function () {
// handle horizontal resizing
});
$(window).on('vresize', function () {
// handle vertical resizing
});
Got better solution:
$('#element').resizable({
stop: function( event, ui ) {
$('#element').height(ui.originalSize.height);
}
});
As a complement to Doublesharp's useful answer:
In my case, window.outerWidth worked better, and was stable to vertical resizes.
Indeed, I had some troubles with $(window).width() : it (strangely!) happened to be modified also when I only resized vertically.
