将对象添加到URL中作为参数

  1. const params2Url = (uri, params) => {
  2.   const paramsArray = [];
  3.   Object.keys(params).forEach(
  4.     (key) => params[key] && paramsArray.push(`${key}=${params[key]}`)
  5.   );
  6.   if (uri.search(/\?/) === -1) {
  7.     uri += `?${paramsArray.join("&")}`;
  8.   } else {
  9.     uri += `&${paramsArray.join("&")}`;
  10.   }
  11.   return uri;
  12. };
  13. let params = {
  14.   keyword: "t",
  15.   page: 1,
  16.   size: 2,
  17. };
  19. params2Url('/datasource/check/p', params)

提取出url 里的参数并转成对象

  1. function getUrlParams(url){
  2.   let reg = /([^?&=]+)=([^?&=]+)/g
  3.   let obj = { }
  4.   url.replace(reg, function(){
  5.       obj[arguments[1]] = arguments[2]
  6.   })
  7.   // 或者
  8.   const search = window.location.search
  9.   search.replace(/([^&=?]+)=([^&]+)/g, (m, $1, $2)=>{obj[$1] = decodeURIComponent($2)})
  11.   return obj
  12. }
  13. let url = 'https://www.junjin.cn?a=1&b=2'
  14. console.log(getUrlParams(url)) // { a: 1, b: 2 }
