我有一个问题我无法解决尝试使用redux-form。我正在尝试Erikras样板。我希望表单是一个组件,而父级调用handleSubmit(目前使用console.log来确认它是否有效)。在这里,两个:
import React, {Component, PropTypes} from 'react';
import Helmet from 'react-helmet';
import {initialize} from 'redux-form';
import {connect} from 'react-redux';
import * as membersActions from 'redux/modules/members';
import {isLoaded, loadMembers} from 'redux/modules/members';
import { DashboardList } from 'components';
import { DashboardHeader } from 'components';
import { DashboardAdding } from 'components';
import { asyncConnect } from 'redux-async-connect';
@asyncConnect([{
deferred: true,
promise: ({store: {dispatch, getState}}) => {
if (!isLoaded(getState())) {
return dispatch(loadMembers());
}
}
}])
@connect(
state => ({
members: state.members.data,
error: state.members.error,
loading: state.members.loading
}),
{...membersActions, initialize })
export default class Dashboard extends Component {
static propTypes = {
initialize: PropTypes.func.isRequired,
members: PropTypes.array,
loadMembers: PropTypes.func.isRequired
}
handleSubmit = (data) => {
console.log(data);
this.props.initialize('dashAdding', {});
}
handleInitialize = () => {
this.props.initialize('dashAdding', {
pseudo: 'Pibo',
email: 'pibirino@gmail.com'
});
}
render() {
const {members} = this.props;
return (
<div className="container">
<h1>Dashboard</h1>
<Helmet title="Dashboard"/>
<DashboardHeader />
<div>
<DashboardList members={members}/>
<h3>Ici commence le form</h3>
<div style={{textAlign: 'center', margin: 15}}>
<button className="btn btn-primary" onClick={this.handleInitialize}>
<i className="fa fa-pencil"/> Initialize Form
</button>
</div>
</div>
<DashboardAdding onSubmit={this.handleSubmit}/>
<p>Bleeeeah!!</p>
</div>
);
}
}
这里的孩子:
import React, {Component, PropTypes} from 'react';
import {reduxForm} from 'redux-form';
import {connect} from 'react-redux';
import {bindActionCreators} from 'redux';
import memberValidation from './memberValidation';
@reduxForm({
form: 'dashAdding',
fields: ['pseudo', 'email'],
validate: memberValidation
})
export default class DashboardAdding extends Component {
static propTypes = {
fields: PropTypes.object.isRequired,
handleSubmit: PropTypes.func.isRequired,
resetForm: PropTypes.func.isRequired
}
render() {
const {
fields: { pseudo, email},
handleSubmit,
resetForm
} = this.props;
const renderInput = (field, label) =>
<div className={'form-group' + (field.error && field.touched ? ' has-error' : '')}>
<label htmlFor={field.name} className="col-sm-2">{label}</label>
<div className={'col-sm-8 '}>
<input type="text" className="form-control" id={field.name} {...field}/>
</div>
</div>;
return (
<div>
<form className="form-horizontal" onSubmit={handleSubmit}>
{renderInput(pseudo, 'Full Name')}
{renderInput(email, 'Email', true)}
<div className="form-group">
<div className="col-sm-offset-2 col-sm-10">
<button className="btn btn-success" onClick={handleSubmit}>
<i className="fa fa-paper-plane"/> Submit
</button>
<button className="btn btn-warning" onClick={resetForm} style={{marginLeft: 15}}>
<i className="fa fa-undo"/> Reset
</button>
</div>
</div>
</form>
</div>
);
}
}
所以...它不起作用我想我缺少一些重要的知识。我认为原因是因为表单组件是哑的,并且它没有调度功能。所以,我尝试从特定文件夹中添加这个(以几种不同的方式多次)导入动作创建者:
@connect(() => ({}),
dispatch => actionCreators( dispatch)
)
但我仍然没有得到我想要的东西。有什么问题?
答案 0 :(得分:0)
所以,最后我自己找到了答案。事实上,我决定不使用@connect,whitch已弃用(尽管它仍在样板文件中使用)并使用connect,如redux-form文档的示例中所示。唯一的变化涉及父母,但我会发布他们两个以防我错过了什么。以下代码效果很好。
以下是代码:
import React, {Component, PropTypes} from 'react';
import Helmet from 'react-helmet';
import {initialize} from 'redux-form';
import {connect} from 'react-redux';
import * as membersActions from 'redux/modules/members';
import {isLoaded, loadMembers} from 'redux/modules/members';
import { DashboardList } from 'components';
import { DashboardHeader } from 'components';
import { DashboardAdding } from 'components';
import { asyncConnect } from 'redux-async-connect';
@asyncConnect([{
deferred: true,
promise: ({store: {dispatch, getState}}) => {
if (!isLoaded(getState())) {
return dispatch(loadMembers());
}
}
}])
class Dashboard extends Component {
static propTypes = {
members: PropTypes.array,
error: PropTypes.string,
loading: PropTypes.bool,
addMember: PropTypes.func,
initialize: PropTypes.func.isRequired,
newMemberData: PropTypes.object
}
handleSubmit = (data, dispatch) => {
dispatch(addMember(JSON.stringify(data)));
this.props.initialize('dashboardForm', {});
}
handleInitialize = () => {
this.props.initialize('dashboardForm', {
pseudo: 'Pibo',
email: 'pibirino@gmail.com'
});
}
render() {
const {members} = this.props;
return (
<div className="container">
<h1>Dashboard</h1>
<Helmet title="Dashboard"/>
<DashboardHeader />
<div>
<DashboardList members={members}/>
<h3>Ici commence le form</h3>
<div style={{textAlign: 'center', margin: 15}}>
<button className="btn btn-primary" onClick={this.handleInitialize}>
<i className="fa fa-pencil"/> Initialize Form
</button>
</div>
</div>
<DashboardAdding onSubmit={this.handleSubmit}/>
</div>
);
}
}
function mapStateToProps(state) {
return {
members: state.members.data,
error: state.members.error,
loading: state.members.loading,
newMemberData: state.addSingleMember.data
};
}
function matchDispatchToProps(dispatch) {
return bindActionCreators({
addActions,
initialize: initialize
}, dispatch);
}
export default connect(mapStateToProps, matchDispatchToProps)(Dashboard);
...和子组件:
import React, {Component, PropTypes} from 'react';
import {reduxForm} from 'redux-form';
import memberValidation from './memberValidation';
class DashboardAdding extends Component {
static propTypes = {
fields: PropTypes.object.isRequired,
handleSubmit: PropTypes.func.isRequired,
resetForm: PropTypes.func.isRequired
}
render() {
const {
fields: { pseudo, email},
handleSubmit,
resetForm
} = this.props;
const renderInput = (field, label) =>
<div className={'form-group' + (field.error && field.touched ? ' has-error' : '')}>
<label htmlFor={field.name} className="col-sm-2">{label}</label>
<div className={'col-sm-8 '}>
<input type="text" className="form-control" id={field.name} {...field}/>
{field.error && field.touched && <div className="text-danger">{field.error}</div>}
</div>
</div>;
return (
<div>
<form className="form-horizontal" onSubmit={handleSubmit.bind(this)}>
{renderInput(pseudo, 'Pseudo')}
{renderInput(email, 'Email', true)}
<div className="form-group">
<div className="col-sm-offset-2 col-sm-10">
<button className="btn btn-success" onClick={handleSubmit}>
<i className="fa fa-paper-plane"/> Submit
</button>
<button className="btn btn-warning" onClick={resetForm} style={{marginLeft: 15}}>
<i className="fa fa-undo"/> Reset
</button>
</div>
</div>
</form>
</div>
);
}
}
export default reduxForm({
form: 'dashboardForm',
fields: ['pseudo', 'email'],
validate: memberValidation,
asyncBlurFields: ['email']
})(DashboardAdding);
addMember函数显然包含一个promise。 我希望它会帮助某人: - )
