Responsive Bootstrap Toolkit

Responsive Bootstrap Toolkit provides an easy way of breakpoint detection in JavaScript, detecting changes in currently active breakpoint, as well as executing any breakpoint-specific JavaScript code. Despite the name, you can use it also with Foundation, or any other framework.

Current version: 2.6.3

Demo

Live example available on CodePen. Hosted along with repository are the following usage examples:

Basic usage:

// Wrap IIFE around your code
(function($, viewport){
    $(document).ready(function() {

        // Executes only in XS breakpoint
        if(viewport.is('xs')) {
            // ...
        }

        // Executes in SM, MD and LG breakpoints
        if(viewport.is('>=sm')) {
            // ...
        }

        // Executes in XS and SM breakpoints
        if(viewport.is('<md')) {
            // ...
        }

        // Execute code each time window size changes
        $(window).resize(
            viewport.changed(function() {
                if(viewport.is('xs')) {
                    // ...
                }
            })
        );
    });
})(jQuery, ResponsiveBootstrapToolkit);

Execute code on window resize

Allows using custom debounce interval. The default one is set at 300ms.

$(window).resize(
    viewport.changed(function() {

      // ...

    }, 150)
);

Get alias of current breakpoint

$(window).resize(
    viewport.changed(function() {
        console.log('Current breakpoint: ', viewport.current());
    })
);

Using with Foundation

Instead of Bootstrap's aliases xs, sm, md and lg, Foundation uses: small, medium, large, and xlarge.

(function($, viewport){

    viewport.use('Foundation');

    if(viewport.is('small')) {
        // ...
    }

})(jQuery, ResponsiveBootstrapToolkit);

Note: Currently, only Foundation 5 visibility classes are supported. If you'd like to support older version of any framework, or provide your own visibility classes, refer to example below.

Providing your own visibility classes

(function($, viewport){

    var visibilityDivs = {
        'alias-1': $('<div class="device-alias-1 your-visibility-class-1"></div>'),
        'alias-2': $('<div class="device-alias-2 your-visibility-class-2"></div>'),
        'alias-3': $('<div class="device-alias-3 your-visibility-class-3"></div>')
    };

    viewport.use('Custom', visibilityDivs);

    if(viewport.is('alias-1')) {
        // ...
    }

})(jQuery, ResponsiveBootstrapToolkit);

Note: It's up to you to create media queries that will toggle div's visibility across different screen resolutions. How? Refer to this example.
