I need to implement a functionality in React that removes a specific CSS class from an item when clicking on that item's button, triggering the appearance of a menu. Here is my code snippet.
import "./Homepage.css"
import React, { useState, useEffect, useRef } from "react"
// import { FontAwesomeIcon } from "@fortawesome/react-fontawesome"
// import { faArrowDown } from "@fortawesome/free-solid-svg-icons"
import { Link } from "react-router-dom"
import useFetch from "./useFetch"
import Axios from "axios"
export default function Homepage() {
const [body, setBody] = useState("")
const [sortedData, setSortedData] = useState("")
const [data, setData] = useState("")
const [css, setCss] = useState("")
const [flash, setFlash] = useState(null)
const posts = useFetch("http://localhost:5000/api/data")
const firstRender = useRef(true)
useEffect(() => {
let test = JSON.parse(window.localStorage.getItem("user"))
console.log(test)
setData(posts)
}, [posts])
useEffect(() => {
if (firstRender.current) {
firstRender.current = false
return
}
data.sort(function (a, b) {
return new Date(b.date) - new Date(a.date)
})
setSortedData(data)
}, [data])
const handleSubmit = (e) => {
e.preventDefault()
Axios.post("http://localhost:5000/api/react-create-post", { text: body }, { withCredentials: true })
.then((res) => {
setSortedData((prevArray) => [res.data.post, ...prevArray])
setFlash("Successfully created post.")
setCss("success-msg")
setBody("")
})
.catch((err) => {
setCss("error-msg")
setFlash("Field cannot be left blank.")
})
}
const handleClick = (e) => {
e.preventDefault()
e.target.parentElement.children[1]
}
return (
<div>
<center>
<div className="create-container">
<div className="posts-title">Create Post</div>
<form id="theForm" onSubmit={(e) => handleSubmit(e)}>
<textarea onChange={(e) => setBody(e.target.value)} value={`${body}`} id="theInput" className="post-input" name="text" type="text"></textarea>
<button className="submit-btn">POST</button>
</form>
</div>
<div id="postsContainer" className="posts-container">
<div className="posts-title">Latest Posts</div>
{flash ? <div className={css}>{flash}</div> : console.log()}
<div id="postInput">
{sortedData &&
sortedData.map((item) => {
return (
<div className="post-container" key={item._id}>
<Link className="a" to={`/user/${item.author}`}>
<h3 className="author">{item.author}</h3>
</Link>
<div className="date">{item.date.toLocaleString()}</div>
<div className="options-cont">
<button onClick={(e) => handleClick(e)} id="optionsBtn" className="options-btn">
<i className="fas fa-ellipsis-v"></i>
</button>
<button data-author={`${item.author}`} data-id={`${item._id}`} data-text={`${item.body}`} id="editBtn" className="edit inside-btn invisible">
Edit
</button>
<button data-author={`${item.author}`} data-id={`${item._id}`} id="deleteBtn" className="delete inside-btn invisible">
Delete
</button>
<br></br>
</div>
<p className="body-text">{item.body}</p>
</div>
)
})}
</div>
</div>
</center>
</div>
)
}
In my understanding, setting the state as the className will affect all items in the "sortedData" array rather than just one item. I only want the menu for a specific item to appear.
