function getQueryVariable() {    let query = window.location.search.substring(1);    let vars = query.split("&");    let res = {};    for (let i = 0; i < vars.length; i++) {        let pair = vars[i].split("=");        if (pair[0] !== "") {            let val = decodeURIComponent(pair[1]);            if (val.includes("|")) {                val = val                    .split("|")                    .filter((item) => item !== "")                    .join(",");            }            if (val === "null") val = "";            res[pair[0]] = val;        }    }    return res;}
