Check the current visibility of bootstrap 3 breakpoints.

Why another breakpoint check for bootstrap 3?

The plugin I have created for simple reasons:

I needed something that works and is easy to integrate into existing projects (in my daily work)
I did not want to create a new code in each project. A plugin repository is mostly stable
Bootstrap did not provide its own Javascript API for this
I had fun doing it^^

Installation

You can download the plugin manually or install by composer. ... and the plugin requires jQuery. ;) jQuery must be properly integrated into the page.

Install via Composer (recommended for php projects)

If you do not have Composer, you may install it by following the instructions at getcomposer.org.

You can then install the package using the following command:

php composer.phar require --prefer-dist cakebake/jquery-breakpoint-check "*"

or add

"cakebake/jquery-breakpoint-check": "*"

to the require section of your composer.json file and run php composer.phar update.

Manual Installation

Download:

Include one of the two javascript files from the folder js after jQuery include. For productive projects, you can use the jquery-breakpoint-check.min.js version. For more details see file test.html.

Example:

<script src="js/jquery-breakpoint-check.min.js"></script>

Usage

Is the current screen resolution xs breakpoint?

if ($.isXs()) {
    alert('Is xs breakpoint :)');
}

Is the current screen resolution sm breakpoint?

if ($.isSm()) {
    alert('Is sm breakpoint :)');
}

Is the current screen resolution md breakpoint?

if ($.isMd()) {
    alert('Is md :)');
}

Is the current screen resolution lg breakpoint?

if ($.isLg()) {
    alert('Is lg breakpoint :)');
}

Is the current screen resolution custom breakpoint?

Create a CSS-Class with visibility for your custom breakpoint. For example:

.visible-grid-float-breakpoint {
    @media (min-width: @grid-float-breakpoint-max) {
        display: none;
        visibility: hidden;
    }
}

if ($.isBreakpoint('grid-float-breakpoint')) {
    alert('It is my custom breakpoint :)');
}

Check the current breakpoint on screen resize.

$(window).resize(function () {
    if ($.isXs()) {
        alert('Is xs breakpoint :)');
    } else if ($.isSm()) {
        alert('Is sm breakpoint :)');
    } else if ($.isMd()) {
        alert('Is md :)');
    } else if ($.isLg()) {
        alert('Is lg breakpoint :)');
    }
}).resize();

Hide a div on xs and lg breakpoint.

$(window).resize(function () {
    var selector = $("div.selector");
    if ($.isXs() || $.isLg()) {
        selector.hide();
    } else {
        selector.hide();
    }
}).resize();
