These are the properties of each of the movie card
这就是onKeyPress:
onKeyPress={ onFavoritesSearch(event.target.value)}
我需要将该值传递到我的函数中,这就是我到目前为止的内容:
onFavoritesSearch = (event) => {
if (event.key === "Enter") {
this.state.sortedFavorites.filter(movie => movie.title.indexOf(event.target.value) === 0)
}
}
如何在函数内部传递输入值?
答案 0 :(得分:1)
您应该在课堂上尝试以下方法:
filterFavoriteMovies = (search) => {
this.state.favorites.filter(movie => movie.title.indexOf(search) === 0)
}
然后将其命名为this.filterFavoriteMovies(evt.target.value)
尽管我建议您在函数中全部处理,但不建议在JSX(reason from the official docs)中声明函数
它看起来像这样:
filterFavoriteMovies = (event) => {
if (event.key === "Enter") {
this.state.favorites.filter(movie => movie.title.indexOf(event.target.value) === 0)
}
}
在您的JSX中,例如:onKeyPress={this.filterFavoriteMovies}
