//under ES6 
const getUrlParamAsObject = (url = window.location.href) => {
    let searchParams = url.split('?')[1];
    const result = {};
    //in case the queryString is empty
    if (searchParams!==undefined) {
        const paramParts = searchParams.split('&');
        for(let part of paramParts) {
            let paramValuePair = part.split('=');
            //exclude the case when the param has no value
            if(paramValuePair.length===2) {
                result[paramValuePair[0]] = decodeURIComponent(paramValuePair[1]);
            }
        }

    }
    return result;
}
