字符串解析的方式

let queryParams = function(_url) {
  let params = {};
  let url = _url || location.search;
  let arr = (url.indexOf('?') > -1 ? url.substr(1) : url).split("&");
  let len = arr.length;
  for(let i=0;i<len;i++) {
    let item = arr[i] && arr[i].split('=');
    params[item[0]] = item[1]
  }
  return params;
}

let res =  queryParams('?name=zhansgan&age=25');

正则表达式

let queryParams = function(_url) {
  let params = {};
  let url = _url || location.search;
  let arr = (/^[?#]/.test(url) ? url.substr(1) : url).split("&");
  let len = arr.length;
  for(let i=0;i<len;i++) {
    let item = arr[i] && arr[i].split('=');
    params[item[0]] = item[1]
  }
  return params;
}

let res =  queryParams('name=zhansgan&age=215');
