【问题描述】:
我正在使用 React.js 构建一个搜索引擎,我可以在其中使用他们的 API 查找 GIPHY gif。每次我输入一个单词(任何单词)时,它总是加载相同的 gif,当我擦除和写入另一个单词时,gif 不会更新。
index.js:
import React from 'react'; //react library
import ReactDOM from 'react-dom'; //react DOM - to manipulate elements
import './index.css';
import SearchBar from './components/Search';
import GifList from './components/SelectedList';
class Root extends React.Component { //Component that will serve as the parent for the rest of the application.
constructor() {
super();
this.state = {
gifs: []
}
this.handleTermChange = this.handleTermChange.bind(this)
}
handleTermChange(term) {
console.log(term);
let url = 'http://api.giphy.com/v1/gifs/search?q=${term.replace(/\s/g, '+')}&api_key=aOfWv08Of7UqS6nBOzsO36NDvwYzO6io';
fetch(url).
then(response => response.json()).then((gifs) => {
console.log(gifs);
this.setState({
gifs: gifs
});
});
};
render() {
return (
<div>
<SearchBar onTermChange={this.handleTermChange} />
<GifList gifs={this.state.gifs} />
</div>
);
}
}
ReactDOM.render( <Root />, document.getElementById('root'));
search.js
import React, { PropTypes } from 'react'
import './Search.css'
class SearchBar extends React.Component {
onInputChange(term) {
this.props.onTermChange(term);
}
render() {
return (
<div className="search">
<input placeholder="Enter text to search for gifs!" onChange={event => this.onInputChange(event.target.value)} />
</div>
);
}
}
export default SearchBar;
Giflist:
import React from 'react';
import GifItem from './SelectedListItem';
const GifList = (props) => {
console.log(props.gifs);
const gifItems = props.gifs && props.gifs.data && props.gifs.data.map((image) => {
return <GifItem key={image.id} gif={image} />
});
return (
<div className="gif-list">{gifItems}</div>
);
};
export default GifList;
GifItem:
import React from 'react';
const GifItem = (image) => {
return (
<div className="gif-item">
<img src={image.gif.images.downsized.url} />
</div>
)
};
export default GifItem;
我似乎找不到问题出在哪里。是不是因为this.handleTermChange = this.handleTermChange.bind(this)之后没有“更新”状态?
欢迎任何帮助 :) 谢谢!

你能显示
GifList组件吗? -
