How to upload useState and submit it to Firestore using single click-CodePudding

const favAnime = async (anime) => {
        setFavani(anime.title)
        setImg(anime.image_url)
        setScore(anime.score)
        setEpisodes(anime.episodes)
        setSynopsis(anime.synopsis)
        setUrl(anime.url)

      const addAnime= await addDoc(collection(db,"Users", uid,"fav"),{
        favani,img,score,episodes,synopsis,url
      })
  }

When I submit, the states updates but firebase receives empty state value, I did add the if function to upload to firebase only when state is not empty but it ended up submitting data of previous click

<div className={styles.grid}>
      {data.map(function(anime){  
        if(data){
        
      return <div className={styles.card}>
          <img src={anime.image_url}/>
        <div className={styles.wrap}>
          <h1>{anime.title}</h1>
          <p>Score: {anime.score}</p>
          <button onClick={()=>{favAnime(anime)}}>add</button>
        </div>
        </div>}})}
    </div>

CodePudding user response：

just add Promise of a timeout to wait until your state updates. modify your function like this

const favAnime = async (anime) => {
        setFavani(anime.title)
        setImg(anime.image_url)
        setScore(anime.score)
        setEpisodes(anime.episodes)
        setSynopsis(anime.synopsis)
        setUrl(anime.url)

      await new Promise((resolve) => setTimeout(resolve, 350))

      const addAnime= await addDoc(collection(db,"Users", uid,"fav"),{
        favani,img,score,episodes,synopsis,url
      })
  }

or you can use data directly from anime parameter

const favAnime = async (anime) => {
  setFavani(anime.title);
  setImg(anime.image_url);
  setScore(anime.score);
  setEpisodes(anime.episodes);
  setSynopsis(anime.synopsis);
  setUrl(anime.url);

  const addAnime = await addDoc(collection(db, 'Users', uid, 'fav'), {
    favani: anime.title,
    img: anime.image_url,
    score: anime.score,
    episodes: anime.episodes,
    synopsis: anime.synopsis,
    url: anime.url
  });
};
