What is the best way to ensure that navigation takes up the full width of the screen in pixels when

Trying to use jQuery to set a specific pixel width for my Bootstrap navbar that spans the entire width of the browser window. However, encountering some bugs as the width needs to be recalculated whenever the browser is resized.

Currently, I have this code which sets the initial width of 'nav' as 'navsize', but it doesn't update properly upon window resize:

$(document).on('ready', function () {
    $(window).on('resize', function () {
        var navsize = $('nav').width();
        $('nav').css('width', navsize);
    }).trigger('resize');
});

I've also tried using $('nav').innerWidth() without success.

The resize function is triggered correctly as confirmed by testing with console.log().

This customization is necessary because I'm using StickyJS to keep my navigation bar fixed while scrolling, but the percentage-based width causes issues when the navbar leaves its container upon scroll.

Answer №1

This method is effective

    $(document).on('ready', function () {
    $(window).on('resize', function () {
        $('nav').css('width', 'calc(100% + 1px  - 1px)' );
        console.log( $('nav').width() );

        ///  Only use the code below if you want to specifically set the width in pixels
        $('nav').width($('nav').width());
    }).trigger('resize');
});

The console.log will display the width in pixels. This means that whenever you check the width in the future, it will be in pixels.

calc(100% + 1px - 1px) converts the width and sets it in px units, which can be easily read later on.

Is $('nav') really there?

I ran some tests on a simple bootstrap page and made a slight tweak to your code that seemed to do the trick.

Go to this page and open the console in your browser:

http://getbootstrap.com/examples/starter-template/

Copy and paste the code below, and you'll see that the width of the .navbar element gets logged when you resize the window:

$(window).on('resize', function () {
    var navsize = $('.navbar').width();
    console.log(navsize)
});

Cheers!

Although it would be more helpful to have the supporting HTML and CSS, I will make an educated guess based on the observed behavior.

Possible Explanation: It appears that one of the following scenarios is likely to be the cause.

You may have intended to use #nav, .nav, div.nav, or a similar selector instead of targeting a specific "nav" element
Your "nav" element may not be displaying as inline-block or block, which can vary across different browsers
You might be using the "nav" tag in a browser that does not support it (such as IE 8)
Your JavaScript library may not recognize the "nav" tag

Suggested Solution: Consider using JavaScript to reposition your navigation menu within the body of the document at a suitable scroll depth, ensuring that your html, body, and nav elements have a width of 100%

I hope this information proves useful for you.
