javascript - 如何从 react.js 中的 redux 存储向引导表插入数据?
问题描述
我在 redux 存储中有数据(数组)。我已经为它创建了动作和减速器,但是如何将已经存储在 redux 存储中的数据显示到我的引导表中?
我的功能组件有表:
const Contacts = function () {
return (
<div>
<table class="table table-dark">
<thead>
<tr>
<th scope="col">#</th>
<th scope="col">First</th>
<th scope="col">Last</th>
<th scope="col">Handle</th>
</tr>
</thead>
<tbody>
<tr>
<th scope="row">1</th>
<td>Mark</td>
<td>Otto</td>
<td>@mdo</td>
</tr>
</tbody>
</table>
</div>
)
}
我的 redux 商店:
从“redux”导入 {createStore} 从“redux-devtools-extension”导入 {composeWithDevTools}
常量初始状态 = {
contacts:[ { "id": 1, "name": "Leanne Graham", "username": "Bret", "email": "Sincere@april.biz", "address": { "street": "Kulas Light", "suite": "Apt. 556", "city": "Gwenborough", "zipcode": "92998-3874", "geo": { "lat": "-37.3159", "lng": "81.1496" } }, "phone": "1-770-736-8031 x56442", "website": "hildegard.org", "company": { "name": "Romaguera-Crona", "catchPhrase": "Multi-layered client-server neural-net", "bs": "harness real-time e-markets" } }, { "id": 2, "name": "Ervin Howell", "username": "Antonette", "email": "Shanna@melissa.tv", "address": { "street": "Victor Plains", "suite": "Suite 879", "city": "Wisokyburgh", "zipcode": "90566-7771", "geo": { "lat": "-43.9509", "lng": "-34.4618" } }, "phone": "010-692-6593 x09125", "website": "anastasia.net", "company": { "name": "Deckow-Crist", "catchPhrase": "Proactive didactic contingency", "bs": "synergize scalable supply-chains" } }, { "id": 3, "name": "Clementine Bauch", "username": "Samantha", "email": "Nathan@yesenia.net", "address": { "street": "Douglas Extension", "suite": "Suite 847", "city": "McKenziehaven", "zipcode": "59590-4157", "geo": { "lat": "-68.6102", "lng": "-47.0653" } }, "phone": "1-463-123-4447", "website": "ramiro.info", "company": { "name": "Romaguera-Jacobson", "catchPhrase": "Face to face bifurcated interface", "bs": "e-enable strategic applications" } }, { "id": 4, "name": "Patricia Lebsack", "username": "Karianne", "email": "Julianne.OConner@kory.org", "address": { "street": "Hoeger Mall", "suite": "Apt. 692", "city": "South Elvis", "zipcode": "53919-4257", "geo": { "lat": "29.4572", "lng": "-164.2990" } }, "phone": "493-170-9623 x156", "website": "kale.biz", "company": { "name": "Robel-Corkery", "catchPhrase": "Multi-tiered zero tolerance productivity", "bs": "transition cutting-edge web services" } } ] } const contactReducer =(state=initialState,action)=> { switch(action.type){ default: return state; } } const store=createStore(contactReducer,composeWithDevTools()) export default store;
解决方案
您可以使用react-redux
并获取状态。您可以在此处查看示例
import { useSelector } from 'react-redux'
const Contacts = function () {
//choose your reducer from store
const data = useSelector(state => state.yourReducerName)
//data for use
<tbody>
{data.map(contact => (
<tr>
<th scope="row">{contact.id}</th>
<td>{contact.name}</td>
<td>{contact.username}</td>
<td>{contact.email}</td>
</tr>
))}
</tbody>
}
