如何在没有 <Link> 标签的情况下使用 react-router-dom 发送参数
How to send params using react-router-dom without a <Link> tag
我正在将 react-router-dom v^6.0.0-beta.1 与 React v^17.0.1 一起使用,我通过点击一张卡片从一页导航到另一页卡片列表:

};
const handleSelect = () => {

};

我想发送用户点击的任何卡片的data.id
。
有什么方法可以使用 onClick 函数将 data.id
作为参数发送到这里:
<div key={data.id}>
<Card
css={css`
display: flex;
width: 500px;
height: 200px;
flex-direction: column;
//border: 2px solid black;
box-shadow: 0 3px 7px 0 rgba(30, 38, 46, 0.21);
cursor: pointer;
:hover {
transform: scale(
1.2
); /* (150% zoom - Note: if the zoom is too large, it will go outside of the viewport) */
}
`}
onClick={handleSelect}
>
并以某种方式发送到这里:
const handleSelect = () => {
navigate('../Player');
};
然后在另一个页面上使用该 ID?
编辑:
这就是我现在正在尝试的:
onClick={() => handleSelect(data.id)}
我认为这是正确的。然后在handleSelect函数中:
const handleSelect = (id: number) => {
history.push(pathname: '/Player',
state: {
id: id,
},)
}
但是我在这方面遇到了 3 个错误:Property 'push' does not exist on type 'History'.ts(2339)
和 Cannot find name 'pathname'.ts(2304)
以及 state
.
的相同错误
编辑 2:
我添加了 const history = useHistory();
并更新了 handleSelect 函数如下:
const handleSelect = (id: number) => {
history.push({
pathname: '/Player',
state: {
id: id,
},
});
};
一切似乎都很好,除了打字稿错误 Module '"react-router-dom"' has no exported member 'useHistory'.ts(2305)
。
使用这个:
onClick={()=>handleSelect(data.id)}
并按如下方式修改您的 handleSelect
:
const handleSelect = (id) => {
this.props.router.push({
pathname: '/pathname',
state: {
id: id
}
})
};
或使用useHistory
:
const handleSelect = (id) => {
history.push(pathname: '/YOUR PATH',
state: {
id: id,
},)
}
您的编辑部分:
- 导入 useHistory 并使用它:
import { useHistory } from "react-router-dom";
// in your component define a history variable
const history = useHistory();
// then use it whenever you want:
history.push({
pathname: '/your path', //change the value to whatever you want
state: {
id: id, // you can add other variables as well
},
});
- 现在您可以在目标组件中访问此变量:
在 class 组件中:
this.props.location
在功能组件中:
import { useLocation } from 'react-router-dom';
const location = useLocation();
let id = location.state.id;
在您的 handleSelect
方法中,您需要传递 data.id
参数。
onClick={handleSelect(data.id)}
并在您的处理程序中处理它。但是你必须像这样包装函数。
const handleSelect = (clickEvent) => (dataId) {
//dataId will be available to use here
navigate('../Player/');
};
然后我会看一下 useHistory
挂钩,因为 history 道具被认为是遗留的。
import React from 'react';
import { useHistory } from 'react-router-dom';
const Hello = () => {
const history = useHistory();
const handleClick = () => history.push('/goodbye');
return (
<button type="button" onClick={handleClick}>
Goodbye
</button>
);
};
export default Hello;
因此,当您推送到历史记录时 URL,您可以创建一个使用该参数的路由。像这样:
history.push('/yourURL/:dataId');
然后在该页面上,您可以下拉该参数,您的应用程序可以使用它。
