为了使其正常工作,我更改了formfilter.js实现:
import React, { Component } from "react";
import * as Animated from "react-select/lib/animated";
import AsyncSelect from "react-select/lib/Async";
class FormFilter extends Component {
constructor(props) {
super(props);
this.state = {
inputValue: "",
selectedOption: "",
genres: []
};
}
selectGenreHandleChange = newValue => {
const inputValue = newValue.replace(/\W/g, "");
this.setState({ inputValue });
console.log(inputValue);
};
componentDidMount() {
this.genresOption();
}
filterGenres = inputValue => {
const genres = this.genresOption();
//HERE - return the filter
return genres.filter(genre =>
genre.label.toLowerCase().includes(inputValue.toLowerCase())
);
};
promiseOptions = inputValue => {
return new Promise(resolve => { // HERE - you have to return the promise
setTimeout(() => {
resolve(this.filterGenres(inputValue));
}, 1000);
});
};
genresOption() {
const options = [];
const genres = this.props.genresList.genres; //HERE - array is genres in genresList
if (genres && genres instanceof Array) {
genres.map(genre => options.push({ value: genre.id, label: genre.name}));
}
return options;
}
render() {
const { inputValue } = this.state;
if (this.state.genres) console.log("state", this.state.genres);
if (this.props.genresList)
console.log("Movies props", this.props.genresList);
return (
<div className="filter_form">
<span className="search_element full">
<label htmlFor="genres">Genres</label>
<AsyncSelect
className="select genres"
classNamePrefix="tmdb_select"
isMulti
isSearchable="true"
isClearable="true"
cacheOptions
components={Animated}
value={inputValue}
defaultOptions
onInputChange={this.selectGenreHandleChange}
loadOptions={this.promiseOptions}
/>
</span>
</div>
);
}
}
export default FormFilter;
我写了一个评论“这里-某物”让你知道我改变了什么。没有大问题:)
