I have a simple voting system (Yes or No) if you click Yes the state needs to be a string up and if you click No the state needs to be down, i need to set local storage in order to prevent the user from keeping voting, do i have to do this in useEffect or just in the voteHandler method, is there an alternative of the local storage ?
Here is my code :
import React, { useState, useContext } from 'react';
import {AnswerContext} from './AnswerWrapper';
const AnswerItem = (props) => {
let indexPlus;
const indexCount = (index) => {
indexPlus = index;
return indexPlus;
}
const { active, setActive } = useContext(AnswerContext)
const [vote, setVote] = useState();
const voteHandler = (e, index, value) => {
e.preventDefault();
localStorage.setItem('myVoteInLocalStorage', value);
setActive(index);
setVote(value)
// I am sending this to a parent component
props.onVote ({
vote : value,
answerID : index
})
}
return (
<div>
<button onClick={(e) => voteHandler(e, props.index, 'up')}>Yes <span>({props.ups !== null ? props.ups : 0 })</span></button>
<button onClick={(e) => voteHandler(e, props.index, 'down')}>No <span>({props.downs !== null ? props.downs : 0 })</span></button>
</div>
)
}
export default AnswerItem;
