正则表达式练习

Question

入参格式参考：

const sourceUrl = "https://www.taobao.com?a=1&b=2&c=3&d#name";

出参格式参考：

const params = {
  a: 1,
  b: 2,
  c: 3,
  d: null
};

"a=1&b=2&c=3&d".match(/\w+(=\d+)?/g)
// ["a=1", "b=2", "c=3", "d"]

第一步处理

var matched = sourceUrl.match(/(?<=\?)(.+)(?=#)/);
var matched = sourceUrl.match(/([^?]+)(?=#)/);
["a=1&b=2&c=3&d", "a=1&b=2&c=3&d", index: 23, 
input: "https://www.taobao.com?a=1&b=2&c=3&d#name", groups: undefined]

第二步处理

matched[1].match(/\w+(=\d+)?/g);
(4) ["a=1", "b=2", "c=3", "d"]
