如何使用JavaScript获取所有查询字符串值

function getQueryStringValues() {
  var queryString = window.location.search.substring(1);
  var params = queryString.split("&");
  var queryParams = {};

  for (var i = 0; i< params.length; i++) {
    var paramPair = params[i].split("=");
    var key = decodeURIComponent(paramPair[0]);
    var value = decodeURIComponent(paramPair[1] || '');
    queryParams[key] = value;
  }

  return queryParams;
}

var queryParams = getQueryStringValues();
console.log(queryParams);
