我有以下组件,我试图将TextInput元素的onSubmitEditing函数设置为名为func的自定义函数。我希望它将TextInput框的内容作为函数的输入。如何才能做到这一点?以下是我尝试这样做的失败:
export default class Component4 extends Component {
func(input){
// will add stuff here later
}
render(){
return (
<View style={{padding: 30}}>
<TextInput placeholder="default" onSubmitEditing=this.func/>
</View>
);
}
}
PS:
感谢大家到目前为止的帮助,我已经设法让它部分工作,现在是我的代码:
export default class Component4 extends Component {
constructor(props) {
super(props);
this.state = {thing: 'asdf'};
}
func(input){
this.state.thing = input;
// I will eventually do more complicated stuff here
}
render(){
return (
<View style={{padding: 30}}>
<TextInput placeholder="default" onSubmitEditing={this.func}/>
<Text>{this.state.thing}</Text>
</View>
);
}
}
这给出了一个错误,我试图让它设置为state.thing 输入。感谢

state={

}
Func(e){
text:e.target.value
}
onSubmitChange={this.func}
不要忘记绑定 func 功能
