获取路由参数工具函数

获取 url 中 msg=info 格式的键值对

方法一：输出所有路由参数的键值对

// 函数：
const getQuerys = (urls) => {
  let url = urls || location.href
  let res = {}
  try {
    const queryString = url ? url.split('?')[1] : window.location.search.slice(1);
    const queryStringArr = queryString.split('&');
    for (var i = 0; i < queryStringArr.length; i++) {
      const param = queryStringArr[i].split('=');
      const paramName = param[0];
      const paramValue = typeof (param[1]) === 'undefined' ? true : param[1];
      res[paramName] = paramValue;
    }
  } catch(err) {
    console.log(err)
  }
  console.log(res)
  return res
}

//使用：
let href = 'https://www.baidu.com/s?wd=你好&rsv_spt=1'
getQuerys(href);
// { wd: "你好", rsv_spt: "1" }

方法二：获取单个参数

const getQueryString = (urls,name) => {
  let url = urls || location.href
  const reg = new RegExp('(^|&)' + name + '=([^&]*)(&|$)', 'i');
  const search = url.split('?')[1]
  const r = search.match(reg) || [];
  return r[2];
}

const url = 'https://www.baidu.com/s?wd=你好&rsv_spt=1'
getQueryString(url,'wd')
// 你好

获取 url 中最后一个 / 后的字符串

const pathName = window.location.pathname
const index: number = pathName.lastIndexOf("\/");
const res: string = pathName.substring(index + 1, pathName.length);
