JS 獲取url問號后面的所有參數

var params = (function oneValues() {
    var query = location.search.substr(1)
    query = query.split('&')
    var params = {}
    for (let i = 0; i < query.length; i++) {
        let q = query[i].split('=')
        if (q.length === 2) {
            params[q[0]] = q[1]
        }
    }
    return params  //返回?號后面的參數名與參數值的數組
}());
