未定义不是对象(评估"事件.目标名称")，当我尝试使注册验证表单反应本机时



undefined不是一个对象(正在评估"event.target-name"(，当我试图使注册验证的表单本地反应时这是我的代码，plzz帮助，非常感谢这是在线文件文档https://docs.google.com/document/d/1WeJtSFEV8zCCy5M_N1pN8SQUFMAmsoQ0-r36iDDunkM/edit?usp=sharing因为我不能上传我的代码不确定为什么

所有相同

您必须通过；name"；道具到您的TextInput组件，如下图所示：

<TextInput
value={this.state.input.username}
onChangeText={this.handleChange}
placeholder={'Tên Đăng Nhập'}
style={Styles.title}
blurOnSubmit={false}
returnKeyType="next"
onSubmitEditing={() => { this.secondTextInput.focus(); }}
id="username"
name="username"
/>

对其余的TextInputs组件执行此操作。

此外，修复您的"；handleChange"；方法，像这样：

handleChange(event) {
this.setState({
input: {
[event.target.name]: event.target.value
}
});
}

handleSubmit(event) {
event.preventDefault();
if (this.validate()) {

});
this.setState((prevState) => {
let errors = Object.assign({}, prevState.errors);
errors.username = null;
errors.password = null;
errors.email = null;
errors.confirm_password = null;
return { errors };
});
alert('Đã Đăng Ký');
}
