Sel*_*vin 6 state reactjs redux antd react-props
我antd在表单中使用设计。
在这里,我profilereducer通过使用shouldComponentUpdate方法来设置减速器的值。
class ProfileForm extends Component {
componentDidMount = () => {
this.props.actions.getprofile()
}
shouldComponentUpdate = (nextProps) => {
if (this.props.profile) {
this.props.form.setFieldsValue({
name: this.props.profile.name,
});
} else {
this.props.form.setFieldsValue({
firstname: 'loading',
});
}
}
render() {
const { getFieldDecorator, getFieldValue } = this.props.form;
<Form layout="vertical">
<FormItem label="First Name" >
{getFieldDecorator('name', { rules: [{ required: true, message: 'Required!', }], })(
<Input addonBefore={selectBefore} placeholder="First Name" />
)}
</FormItem>
</Form>
}
function mapStateToProps(state) {
return {
profile: state.profilereducer.profile,
}
}
function mapDispatchToProps(dispatch) {
return {
actions: bindActionCreators(actions, dispatch)
}
}
const Profile = Form.create()(ProfileForm);
export default connect(mapStateToProps, mapDispatchToProps)(Profile);
}

错误:
您在循环中设置状态,因此出现错误。这是处理它的更好方法.. 我只是将 selectBefore 作为一个变量(在你的代码中,我没有找到设置它)。如果你得到错误,将它更改为字符串..
componentDidMount = () => {
this.props.actions.getprofile()
}
renderBasicform(initialVal) {
const { getFieldDecorator, getFieldValue } = this.props.form;
return (
<Form layout="vertical">
<FormItem label="First Name" >
{getFieldDecorator('name', { initialValue: initialVal,rules: [{ required: true, message: 'Required!', }], })(
<Input addonBefore={selectBefore} placeholder="First Name" />
)}
</FormItem>
</Form>
);
}
render() {
if(!this.props.profile) {
return (
<div>
{this.renderBasicform("Loading")}
</div>
);
}
return (
<div>
{this.renderBasicform(this.props.profile.name)}
</div>
);
}
