這裏是我的代碼附加一個循環內事件偵聽器中反應
import React,{ Component } from 'react';
import PTSearch from 'post-api-search';
export default class Navbar extends Component{
constructor(props) {
super(props);
this.state = {
source: []
};
this.sourceSearch();
}
sourceSearch() {
PTSearch({
category: "",
language: "en",
country: ''
}, "sources", (sources) => {
this.setState({
source: sources
});
});
}
loadSourceContent() {
alert(1);
}
renderSource(data){
return (
<li title={data.description} onClick={this.loadSourceContent} key={data.name}>{data.name}</li>
);
}
render(){
return (
<div>
<button id="menu-toggle" className="menu-toggle"><span>Menu</span></button>
<div id="theSidebar" className="sidebar">
<button className="close-button fa fa-fw fa-close"></button>
<div>
<img src="https://vignette.wikia.nocookie.net/clonewarsadventurescharacter/images/8/81/Superman-logo-transparent.png/revision/latest?cb=20131006162105" />
</div>
<ul className="source-list">
{ this.state.source.slice(0, 10).map(this.renderSource) }
</ul>
</div>
</div>
);
};
}
我想在這個代碼不爲我工作的li.But的每個元素添加一個onclick事件。問題是,當我點擊<li>
元素,它給loadsourcecontent
未定義的錯誤。
在此先感謝和抱歉,我的英語
