javascript - jQuery detect Bootstrap 3 state

Question

In Bootstrap 3, there are 4 states; extra small devices, small devices, medium devices, and large devices. How can I know the website is currently at which state with jQuery? So that I can do some processing like when it is in extra small devices, then run this function.

Thanks.

I made some changes to this for bootstrap 3, try this"

function findBootstrapEnvironment() {
    var envs = ["ExtraSmall", "Small", "Medium", "Large"];
    var envValues = ["xs", "sm", "md", "lg"];

    var $el = $('<div>');
    $el.appendTo($('body'));

    for (var i = envValues.length - 1; i >= 0; i--) {
        var envVal = envValues[i];

        $el.addClass('hidden-'+envVal);
        if ($el.is(':hidden')) {
            $el.remove();
            return envs[i]
        }
    };
}
