es6解析地址栏参数

上函数：

function qs(search) {
  if(typeof search !== "string" || !search) return search;
  return search.split("&").reduce((res, cur) => {
    const arr = cur.split("=");
    return Object.assign({[arr[0]]: arr[1]}, res)
  }, {})
}

const search = location.search.replace(/^\?/, "");
console.log("result:", qs("a=content&q=123"));
result: {a: content, q: 123}
然后利用解构就可以取值了~~
