我试图获取内部输入元素的值,但每次出现此错误时都会:
未捕获的TypeError:this.containerInput.gatValue不是函数
是什么
class Input extends Component {
getValue() {
return this.textInput.value;
}
render() {
return (
<input type="text" ref={(input) => this.textInput = input} />
);
}
}
class Container extends Component {
getValue() {
return this.containerInput.gatValue();
}
render() {
return (
<Input ref={(input) => this.containerInput = input} />
);
}
}
class View extends Component {
constructor(props) {
super(props);
this.buttonClick = this.buttonClick.bind(this);
}
buttonClick(e) {
console.log(this.viewInput.getValue());
}
render() {
return (
<div>
<Container ref={(input) => this.viewInput = input} />
<button onClick={this.buttonClick}>Get Value</button>
<span></span>
</div>
);
}
}
ReactDOM.render(
<View />,
document.getElementById('root')
);
答案 0 :(得分:2)
您的意思是this.containerInput.getValue()还是this.containerInput.textInput.value?
