Remove class using javascript
const removeClass = ($el, className) => {
const _removeClass = function(el) {
if (el.classList) {
el.classList.remove(className);
} else {
el.className = el.className.replace(
new RegExp('(^|\\b)' + className.split(' ').join('|') + '(\\b|$)', 'gi'),
' ',
);
}
};
if ($el.length === 1) {
_removeClass($el);
} else if ($el.length > 1) {
$el.forEach(function(item) {
_removeClass(item);
});
}
};
