在这个示例中,我们在App组件中使用了useState和useEffecthooks 来获取 URL 查询参数,并将获取到的参数存储到了组件的状态中。在页面上,我们则通过遍历params对象来展示每个查询参数的内容。 总的来说,getQueryParams方法是 React Router 提供的一个方便的工具,它可以帮助我们轻松地获取 URL 查询参数,并在我们的应用程序中进行处理和使用。
const paramValue = urlParams.get('paramName'); 使用第三方库:除了React Router,还有一些第三方库可以帮助我们在React中获取URL参数,例如query-string库。该库提供了一些方便的API来解析URL查询参数。以下是一个使用query-string库的示例代码: 代码语言:txt 复制 import queryString from 'query-string'; const par...
const searchParams =newURLSearchParams(search.substring(1)); useEffect(() => { if(searchParams?.get('reportCode')) { individualReportDs?.queryDataSet?.reset(); individualReportDs?.queryDataSet?.create({ reportCode: searchParams.get('reportCode') }, 0); } individualReportDs.query(); }, ...
import { useLocation } from 'react-router-dom'; function SearchResults() { const location = useLocation(); const queryParams = new URLSearchParams(location.search); const searchQuery = queryParams.get('q'); return ( Search Results for: {searchQuery} {/* ... */} ); } 获取路由参数 ...

方式4：react-query/swr 使用 react-query或swr，可以为我们处理缓存、重试、重复查询等等。我不必维护自己的自定义Hook了。而且每个 HTTP 调用都需要很少的代码：import React from"react";import { getUsers } from"./services/userService";import { useQuery } from"react-query";exportdefaultfunctionReactQuery...
this.props.match.params 跳转:<Link to={`/content/${value.aid}`}>{value.title}</Link> react get传值 1、获取 this.props.location.search*/ 2、案例实现路由配置 import React, { Component }from'react'; import { BrowserRouterasRouter, Route, Link }from"react-router-dom"; ...
case, so React URL Query provides a succinct way of describing URL query parameters through itsurlPropsQueryConfig. You can just describe the type and names of the query parameters, and the decoded query params along with their change handlers will be passed in as props to the wrapped ...
{/* 一、传递params参数 */}this.props.history.push(`/home/message/detail/${id}/${title}`) {/* 二、传递search参数(类似Ajax的query) */}this.props.history.push(`/home/message/detail/?id=${id}&title=${title}`) {/* 三、传递state参数 */}this.props.history.push(`/home/message/detail...
import { useQuery } from '../hooks/useQuery' const query = useQuery() const name = query.get('name')复制代码 1. 2. 3. 现在我们试着用props取query,原理和上面一样,所以建议使用上面的方法 const nameParams = new URLSearchParams(props.location.search)console.log(nameParams.get('name'));...
