моя функция поддерживает удаление param

function updateURLParameter(url, param, paramVal, remove = false) {
        var newAdditionalURL = '';
        var tempArray = url.split('?');
        var baseURL = tempArray[0];
        var additionalURL = tempArray[1];
        var rows_txt = '';

        if (additionalURL)
            newAdditionalURL = decodeURI(additionalURL) + '&';

        if (remove)
            newAdditionalURL = newAdditionalURL.replace(param + '=' + paramVal, '');
        else
            rows_txt = param + '=' + paramVal;

        window.history.replaceState('', '', (baseURL + "?" + newAdditionalURL + rows_txt).replace('?&', '?').replace('&&', '&').replace(/\&$/, ''));
    }
