Following is my javascript function, I want to use variable selected outside function, but I am getting selected not defined error in console of inspect element.

function showMe(pause_btn) {
    var selected = [];
    for (var i = 0; i < chboxs.length; i++) {
        if (chboxs[i].checked) {
            selected.push(chboxs[i].value);
        }
    }
}
