[jquery] How to get screen width without (minus) scrollbar?

I have an element and need it's width without(!) vertical scrollbar.

Firebug tells me body width is 1280px.

Either of these work fine in Firefox:

console.log($('.element').outerWidth() );
console.log($('.element').outerWidth(true) );

$detour = $('.child-of-element').offsetParent();
console.log( $detour.innerWidth() );

They all return 1263px, which is the value I'm looking for.

However all other browser give me 1280px.

Is there a cross browser way to get a fullscreen width without(!) vertical scrollbar?

None of these solutions worked for me, however I was able to fix it by taking the width and subtracting the width of the scroll bar. I'm not sure how cross-browser compatible this is.

You can use vanilla javascript by simply writing:

var width = el.clientWidth;

You could also use this to get the width of the document as follows:

var docWidth = document.documentElement.clientWidth || document.body.clientWidth;

You can also get the width of the full window, including the scrollbar, as follows:

var fullWidth = window.innerWidth;

However this is not supported by all browsers, so as a fallback, you may want to use docWidth as above, and add on the scrollbar width.

The safest place to get the correct width and height without the scrollbars is from the HTML element. Try this:

var width = document.documentElement.clientWidth
var height = document.documentElement.clientHeight

Browser support is pretty decent, with IE 9 and up supporting this. For OLD IE, use one of the many fallbacks mentioned here.

I experienced a similar problem and doing width:100%; solved it for me. I came to this solution after trying an answer in this question and realizing that the very nature of an <iframe> will make these javascript measurement tools inaccurate without using some complex function. Doing 100% is a simple way to take care of it in an iframe. I don't know about your issue since I'm not sure of what HTML elements you are manipulating.

Here are some examples which assume $element is a jQuery element:

// Element width including overflow (scrollbar)
$element[0].offsetWidth; // 1280 in your case

// Element width excluding overflow (scrollbar)
$element[0].clientWidth; // 1280 - scrollbarWidth

// Scrollbar width
$element[0].offsetWidth - $element[0].clientWidth; // 0 if no scrollbar

Try this :

$('body, html').css('overflow', 'hidden');
var screenWidth1 = $(window).width();
$('body, html').css('overflow', 'visible');
var screenWidth2 = $(window).width();
alert(screenWidth1); // Gives the screenwith without scrollbar
alert(screenWidth2); // Gives the screenwith including scrollbar

You can get the screen width by with and without scroll bar by using this code. Here, I have changed the overflow value of body and get the width with and without scrollbar.

Here is what I use

function windowSizes(){
    var e = window,
        a = 'inner';
    if (!('innerWidth' in window)) {
        a = 'client';
        e = document.documentElement || document.body;
    }
    return {
        width: e[a + 'Width'],
        height: e[a + 'Height']
    };  
}

$(window).on('resize', function () {
    console.log( windowSizes().width,windowSizes().height );
});
