获取页面参数search的几种方法

1.通过正则

function getUrlParams(url){  const reg = /([^&?#]+)=([^&?#]+)/g;  const obj = {};  url.replace(reg, (...arg) => {    const [, arg1, arg2] = arg;    obj[arg1] = arg2;  })  return obj;}

2.通过字符串拆分

function getUrlParams(Url){    var str = Url;    str = str.split('?')[1];    var arr = str.split("&");    var obj = new Object();    for (var i = 0; i < arr.length; i++) {        var tmp_arr = arr[i].split("=");        obj[decodeURIComponent(tmp_arr[0])] = decodeURIComponent(tmp_arr[1]);    }    return obj;}

3.通过原生格式化

// eg:window.location=http://www.baidu.com?id=10var params = new URLSearchParams(window.location.search);params.get('id')  //10
