所以我代码中的所有内容都按预期工作,仅在第二次或什至在第三次单击按钮时才发送发帖请求...我猜测这与我更新的方式有关redux状态,但是我的大脑呆滞了,有人可以指出我的错误在哪里吗?
干杯!
class AddressScreen extends Component {
state = {
usersNickOrName: "",
usersAddress: "",
usersPhoneNumber: ""
};
onPressHandler = () => {
this.props.deliveryInfo(
this.state.usersNickOrName,
this.state.usersAddress,
this.state.usersPhoneNumber
);
let uid = this.props.uid;
axios.post(
`.../users/${uid}/info.json`,
{
nameOrNick: this.props.name,
address: this.props.address,
phoneNum: this.props.phoneNum
}
);
this.props.navigator.pop();
};
render() {
return (
<View style={styles.container}>
<AnimatedForm delay={100} distance={10}>
<AnimatedInput
onChangeText={text => {
this.setState({ usersNickOrName: text });
}}
/>
<AnimatedInput
onChangeText={text => {
this.setState({ usersAddress: text });
}}
/>
<AnimatedInput
onChangeText={text => {
this.setState({ usersPhoneNumber: text });
}}
/>
<Animated.View style={styles.buttonView}>
<TouchableOpacity
style={styles.button}
onPress={this.onPressHandler}
>
<Text style={{ color: "#fff" }}>Dodaj Info</Text>
</TouchableOpacity>
</Animated.View>
</AnimatedForm>
</View>
);
}
}
const mapStateToProps = state => {
return {
name: state.usersNickOrName,
address: state.usersAddress,
phoneNum: state.usersPhoneNumber,
uid: state.userUid
};
};
const mapDispatchToProps = dispatch => {
return {
deliveryInfo: (usersName, usersAddress, phoneNum) =>
dispatch(deliveryInfo(usersName, usersAddress, phoneNum))
};
};
export default connect(
mapStateToProps,
mapDispatchToProps
)(AddressScreen);
编辑:
我所做的是,我已将redux更新状态放入componentWillUpdate中,并将其从onPressHandler中删除。现在,它的工作几乎像预期的一样,例如,如果我输入London Str。 36它将发布请求London Str。 3,它不会将最后一个字母或数字发送到服务器...怎么了?
componentWillUpdate() {
this.props.deliveryInfo(
this.state.usersNickOrName,
this.state.usersAddress,
this.state.usersPhoneNumber
);
}
答案 0 :(得分:0)
根据我在您的实现中看到的内容,the post request
将始终由按钮(TouchableOpacity
)调用。为防止这种情况发生,您可以采取的措施是实施一项功能,该功能将在尝试触发post request
之前检查是否存在正在进行的a new post request
。
