如何检测ReactJS onKeyPress事件中的“Shift Enter”？
可能吗 ？
https://jsfiddle.net/jacobgoh101/cyLqfcts/3/
class App extends React.Component {
constructor(props) {
super(props);
this.handleKeyPress = this.handleKeyPress.bind(this);
}
handleKeyPress(e) {
console.log(e.key);
$('#app').append("<br/>" + e.key);
}
render() {
return ( < textarea defaultValue = {
""
}
onKeyPress = {
this.handleKeyPress
}
/>
);
}
}
ReactDOM.render(<App/>,document.getElementById('app'));
解决方法
您的答案是检测到“输入”而不是“切换输入”.这应该有帮助！

if (e.key === 'Enter' && e.shiftKey) {
$('#app').append("<br/> Detected Shift+Enter")
}
}
render() {
return (
<textarea
defaultValue = {""}
onKeyUp={this.handleKeyPress}
/>
);
