so i have data from api and mapped over them to present these images:
so i'm trying to do this project and now i'm basically stuck i'm not very good in react and css but i'm learning, and i want to do now is to add remove functionality. i have created a function that removes the picture from the data when i click on the image but what i want is when i hover over the image a red cross will appear and when i press the red cross i can trigger the function and delete the image
code:
import React,{useState,useEffect,useReducer} from 'react';
import axios from 'axios';
import {useForm} from 'react-hook-form';
const Data = () => {
const [photo,setPhoto] = useState([])
useEffect(() => {
axios.get("https://jsonplaceholder.typicode.com/photos").then(
result => {
setPhoto(result.data)
}
)
},[])
const [Url,setUrl] = useState()
const[photoId,setPhotoId] = useState()
const showPicture = (url,id) => {
setUrl(url)
setPhotoId(id)
}
const handleDelete = id => {
setUrl(null);
setPhoto(prevState => prevState.filter(x => x.id !== id));
};
const {register,handleSubmit,errors} = useForm();
const [links,setLinks] = useState({
link:'',
thumbnailLink:'',
title:''
})
const onSubmit = (data) => {
console.log(data)
};
return(
<div>
<div><img src={Url} onClick={() => handleDelete(photoId)}></img></div>
<div>Posts</div>
{/* <p>enter album Id to see the magic</p><input type="text" value={albumId} onChange={e => setAlbumId(e.target.value)}></input>
<button type="button" onClick={handleClick}>Fetch Album</button> */}
<div className="container">
<div>{photo.slice(0,3).map(p =>
<div key={p.id}>
<img src={p.thumbnailUrl} thumbnailUrl={p.thumbnailUrl} onClick={() => showPicture(p.url,p.id)}></img>
<div>{p.title}</div>
</div>
)}</div>
</div>
<form onSubmit={handleSubmit(onSubmit)}>
<input type="url" placeholder="link" name="link" ref={register}/>
<input type="url" placeholder="thumbnail url" name="thumbnail" ref={register}/>
<input type="text" placeholder="title" name="title" ref={register}/>
<input type="submit" />
</form>
</div>
)
}
export default Data;
Use css :hover
to display button upon hover. Write a handler for delete and pass the index
to it and use array splice
to remove photo.
Working demo (hover & close functionality)
Delete Handler
const handleImageDelete = id => {
const updatedPhotos = [...photo];
updatedPhotos.splice(id, 1);
setPhoto(updatedPhotos);
};
JSX
<div>
<div className="container">
<div>
{photo.slice(0, 3).map((p, i) => (
<div className="image" key={p.id}>
<img
alt=""
key={p.id}
src={p.thumbnailUrl}
thumbnailUrl={p.thumbnailUrl}
onClick={() => showPicture(p.url, p.id)}
/>
<div
className="delete"
type="button"
onClick={() => handleImageDelete(i)}
>
X
</div>
<div>{p.title}</div>
</div>
))}
</div>
</div>
</div>
