从“react-router-dom”导入 { useSearchParams }; // 当前路径是/foo?id=12 函数Foo() { const [searchParams, setSearchParams] = useSearchParams(); 安慰。日志(searchParams.get(“id”)); // 12 设置搜索参数({ 名称:“富”, }); // /foo?name=foo 返回 foo</ div > ; } 复制代码 五...
import { useLocation } from "react-router-dom"; import qs from "query-string"; const { search } = useLocation(); //search参数 => {age: "20", name: "zhangsan"} //接收参数方法2: import { useSearchParams } from "react-router-dom"; const [searchParams, setSearchParams] = useSearchP...
import{useParams}from"react-router-dom";exportdefaultfunctionUserDetail(){letparams=useParams();returnUser:{params.id};} useSearchParams相对复杂,他返回的是一个当前值和set方法 let[searchParams,setSearchParams]=useSearchParams(); 使用时可以用searchParams.get("id")来获取参数,同时页面内也可以set...
import { useSearchParams } from "react-router-dom"; // 因是hook,必须写在组件的顶部执行,useSearchParams() 返回的是数组const [params] = useSearchParams();// 通过 get 方法获取目标参数const name = params.get("name") || "";const if_login = params.get("if_login") || false; 登录状态...
使用useSearchParamshook 来访问和修改查询参数。其用法和useState类似,会返回当前对象和更改它的方法 使用setSearchParams时,必须传入所有的查询参数,否则会覆盖已有参数 import{useSearchParams}from"react-router-dom";// 当前路径为 /foo?id=12functionFoo(){const[searchParams,setSearchParams]=useSearchParams();...
import {useParams} from "react-router-dom"; const {id} = useParams(); 如果传递的是search参数(例如:detail?id=1&name=李四)需要使用useSearchParams获取search参数 import {useSearchParams} from "react-router-dom" const [searchParams] = useSearchParams(); const id = searchParams.get("id");...
