vue3获取url地址参数的示例详解

import { useRouter, useRoute } from 'vue-router';
setup() {
	 let router = useRouter();
     let route = useRoute();
 
 }
 function GetRequest(value) {
    var url = decodeURI(window.location.search); //?id="123456"&name="www";
    var object = {};
    if (url.indexOf("?") != -1)//url中存在问号，也就说有参数。  
    {
      var str = url.substr(1);  //得到?后面的字符串
      var strs = str.split("&");  //将得到的参数分隔成数组[id="123456",name="www"];
      for (var i = 0; i < strs.length; i++) {
        object[strs[i].split("=")[0]] = strs[i].split("=")[1];//得到{id:'123456',name:'www'}
      }
    }
    return object[value];
  }

import { createRouter, createWebHistory } from 'vue-router'
